-# RadioLib as Tock application
-
-[Tock](https://github.com/tock/tock) is an embedded operating system designed
-for running multiple concurrent, mutually distrustful applications on Cortex-M
-and RISC-V based embedded platforms.
-
-RadioLib can be built as a Tock application using
-[libtock-c](https://github.com/tock/libtock-c). This is an example of running
-RadioLib as a Tock application.
-
-This has been tested on the
-[SparkFun LoRa Thing Plus - expLoRaBLE board] (https://github.com/tock/tock/tree/master/boards/apollo3/lora_things_plus)
-but will work on any LoRa compatible Tock board (currently only the
-expLoRaBLE board).
-
-The RadioLib example can be built with:
-
-```shell
-$ git clone https://github.com/jgromes/RadioLib.git
-$ cd RadioLib/examples/NonArduino/Tock/
-$ ./build.sh
-```
-
-Then in the Tock repo you can flash the kernel and app with:
-
-```shell
-$ make flash; APP=RadioLib/examples/NonArduino/Tock/build/tock-sx1261.tbf make flash-app
-```

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.

-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include

-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.

-=============
-
-This directory contains libraries and example applications for developing
-Tock apps that sit above the kernel.
-
-
-Prerequisites
--------------
-
-1. If you have not yet done so, it might be a good idea to start with
-   the [TockOS getting started
-   guide](https://github.com/tock/tock/blob/master/doc/Getting_Started.md),
-   which will lead you through the installation of some tools that
-   will be useful for developing and deploying applications on
-   TockOS. In particular, it will give you a rust environment
-   (required to install `elf2tab`) and `tockloader`, which you need to
-   deploy applications on most boards.
-
-   And it will of course give you a board with TockOS installed which
-   you can use to run the applications found in this repository.
-
-   So, if you haven't been there before, just head over there until it
-   sends you back here.
-
-1. Clone this repository.
-
-    ```
-    $ git clone https://github.com/tock/libtock-c
-    $ cd libtock-c
-    ```
-
-1. The main requirement to build the C applications in this repository is having
-   cross compilers for embedded targets. You will need an `arm-none-eabi`
-   toolchain for Cortex-M targets.
-
-   **MacOS**:
-   ```
-   $ brew tap ARMmbed/homebrew-formulae && brew update && brew install arm-none-eabi-gcc
-   ```
-
-   **Ubuntu (18.04LTS or later)**:
-   ```
-   $ sudo apt install gcc-arm-none-eabi
-   ```
-
-   **Arch**:
-   ```
-   $ sudo pacman -Syu arm-none-eabi-gcc arm-none-eabi-newlib
-   ```
-
-   **Fedora**:
-   ```
-   $ sudo dnf install arm-none-eabi-newlib arm-none-eabi-gcc-cs
-   ```
-
-2. Optional: libtock-c also includes support for building for ***RISC-V
-   targets***. These are not included by default since obtaining the toolchain
-   can be difficult (as of July 2022). You will need a RISC-V toolchain that
-   supports rv32 targets (64 bit toolchains support rv32 if compiled with
-   multilib support). Some toolchains that can work:
-
-   - riscv64-none-elf
-   - riscv32-none-elf
-   - riscv64-elf
-   - riscv64-unknown-elf
-   - riscv32-unknown-elf
-
-   To actually build for the RISC-V targets, add `RISCV=1` to the make command:
-
-       $ make RISCV=1
-
-   **MacOS**:
-   ```
-   $ brew tap riscv/riscv && brew update && brew install riscv-gnu-toolchain
-   ```
-
-   **Ubuntu (21.10 or later)**:
-   ```
-   $ sudo apt install gcc-riscv64-unknown-elf picolibc-riscv64-unknown-elf
-   ```
-
-   **Ubuntu (21.04 or earlier)**:
-
-   Unfortunately, older Ubuntu does not provide a package for RISC-V libc. We
-   have created a .deb file you can use to install a suitable libc based on
-   newlib:
-   ```
-   $ wget http://cs.virginia.edu/~bjc8c/archive/newlib_3.3.0-1_amd64.deb
-   $ sudo dpkg -i newlib_3.3.0-1_amd64.deb
-   ```
-
-   If you would rather compile your own newlib-based libc, follow the steps
-   below. Section [newlib-nano](newlib-nano) describes some extra config options
-   to build a size optimised newlib.
-   ```
-   # Download newlib 3.3 from https://sourceware.org/newlib/
-   $ wget ftp://sourceware.org/pub/newlib/newlib-3.3.0.tar.gz
-   $ tar -xvf newlib-3.3.0.tar.gz
-   $ cd newlib-3.3.0
-   # Disable stdlib for building
-   $ export CFLAGS=-nostdlib
-   # Run configure
-   $ ./configure --disable-newlib-supplied-syscalls --with-gnu-ld --with-newlib --enable-languages=c --target=riscv64-unknown-elf --host=x86 --disable-multi-lib --prefix /usr
-   # Build and then install
-   $ make -j8
-   $ sudo make install
-   ```
-
-   Alternatively, you may use a pre-compiled toolchain that we created with
-   Crosstool-NG.
-   ```
-   $ wget http://cs.virginia.edu/~bjc8c/archive/gcc-riscv64-unknown-elf-8.3.0-ubuntu.zip
-   $ unzip gcc-riscv64-unknown-elf-8.3.0-ubuntu.zip
-   # add gcc-riscv64-unknown-elf-8.3.0-ubuntu/bin to your `$PATH` variable.
-   ```
-
-   **Arch**:
-   ```
-   $ sudo pacman -Syu riscv64-elf-gcc riscv32-elf-newlib arm-none-eabi-newlib riscv64-elf-newlib
-   ```
-
-   **Fedora**:
-
-   **dnf** does not contain the `riscv-gnu-toolchain`, an alternative is to
-   compile from source. Start with some of the tools we need to compile the
-   source.
-   ```
-   $ sudo dnf install make automake gcc gcc-c++ kernel-devel  texinfo expat expat-devel
-   $ sudo dnf group install "Development Tools" "C Development Tools and Libraries"
-   ```
-   Get `riscv-gnu-toolchain`,  [summarised instructions as stated
-   here](https://github.com/riscv-collab/riscv-gnu-toolchain/blob/master/README.md)
-   ```
-   $ git clone https://github.com/riscv/riscv-gnu-toolchain
-   $ cd riscv-gnu-toolchain/
-   ```
-   **Note: add /opt/riscv/bin to your PATH**, then,
-   ```
-   $ ./configure --prefix=/opt/riscv --enable-multilib
-   ```
-   `--enable-multilib` ensures that "the multilib compiler will have the prefix
-   riscv64-unknown-elf- or riscv64-unknown-linux-gnu- but will be able to target
-   both 32-bit and 64-bit systems."
-   ```
-   $ sudo make         [might need elevated privileges writing to `/opt/`]
-   ```
-   additionally, with
-   ```
-   $ sudo make linux
-   ```
-   you can also build `riscv64-unknown-linux-gnu`, which can be useful with tock
-   where `riscv64-unknown-linux-gnu-objcopy` is used.
-
-   After the the source has been compiled and copied to `/opt/riscv` and
-   `/opt/riscv/bin`has appended to the PATH, the toolchain is ready to be used.
-
-
-   **newlib-nano**:
-
-   newlib can require a large amount of memory, especially for printing.
-   If this is a concern you can instead use a more size optimised version.
-   As of August 2020 there are a few options for this.
-
-   - See if the version of newlib from your distro already has the flags below
-     enabled. If it does it's already size optimsed.
-   - See if your distro pacakges a newlib-nano (Debian does this) that will
-     already include the flags below.
-   - See if your distro packages picolibc, which is a optimised fork of newlib.
-   - You can compile newlib with these extra flags:
-        ```
-          --enable-newlib-reent-small \
-          --disable-newlib-fvwrite-in-streamio \
-          --disable-newlib-fseek-optimization \
-          --disable-newlib-wide-orient \
-          --enable-newlib-nano-malloc \
-          --disable-newlib-unbuf-stream-opt \
-          --enable-lite-exit \
-          --enable-newlib-global-atexit \
-          --enable-newlib-nano-formatted-io
-        ```
-
-3. Optional: libtock-c also includes support for building RISC-V targets with
-   the LLVM clang compiler. If you have a compatible clang toolchain, you can
-   add `CLANG=1` to the make command to use clang instead of the default GCC.
-
-       $ make RISCV=1 CLANG=1
-
-   This support is only included for RISC-V targets as Cortex-M targets require
-   the FDPIC support only present in GCC.
-
-4. You will also need an up-to-date version of
-   [elf2tab](https://crates.io/crates/elf2tab). The build system will install
-   and update this automatically for you, but you'll need Rust's
-   [cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html)
-   installed. If you have followed the getting started guide, everything should
-   be in place.
-
-5. You will also likely need [Tockloader](https://github.com/tock/tockloader), a
-   tool for programming apps onto boards. If you haven't installed it
-   during the TockOS getting started guide:
-
-   MacOS:
-   ```
-   $ pip3 install tockloader
-   ```
-
-   Ubuntu:
-   ```
-   $ pip3 install tockloader --user
-   ```
-
-Compiling and Running Applications
-----------------------------------
-
-To compile all the examples, switch to the `examples` directory and execute the
-build script:
-
-    $ cd examples
-    $ ./build_all.sh
-
-This will install `elf2tab` if it is not yet installed and compile all the
-examples for cortex-m0, cortex-m3, cortex-m4, cortex-m7, and rv32imac. It does
-this because the compiler emits slightly (or significantly) different
-instructions for each variant. When installing the application, `tockloader`
-will select the correct version for the architecture of the board being
-programmed.
-
-The build process will ultimately create a `tab` file (a "Tock Application
-Bundle") for each example application. The `tab` contains the executable code
-for the supported architectures and can be deployed to a board using
-`tockloader`. For example to one of the Nordic development boards:
-
-```
-$ tockloader install --board nrf52dk --jlink blink/build/blink.tab
-Installing apps on the board...
-Using known arch and jtag-device for known board nrf52dk
-Finished in 2.567 seconds
-```
-
-You can remove an application with
-
-    $ tockloader uninstall --board nrf52dk --jlink blink
-
-or remove all installed applications with
-
-    $ tockloader uninstall --board nrf52dk --jlink
-
-Tock applications are designed to be generic and run on any Tock-compatible
-board. However, compiled applications typically depend on specific drivers,
-which not all boards provide. For example, some applications expect an IEEE
-802.15.4 radio interface which not all boards support. If you load an
-application onto a board that does not support every driver/system call it uses,
-some system calls will return error codes (`ENODEVICE` or `ENOSUPPORT`).
-
-Next Steps
-----------
-
-The next step is to read the [overview](doc/overview.md) that describes how
-applications in TockOS are structured and then look at some of the examples in
-detail. The description of the [compilation environment](doc/compilation.md) may
-also be of interest.

-# Handle complex paths.
-#
-# Okay, so this merits some explanation:
-#
-# Our build system aspires to put everything in build/ directories, this means
-# that we have to match the path of source files (foo.c) to output directories
-# (build/<arch>/foo.o). That's easy enough if all the source files are in the
-# same directory, but restricts applications and libraries to a flat file
-# structure.
-#
-# The current solution we employ is built on make's VPATH variable, which is a
-# list of directories to search for dependencies, e.g.
-#
-#    VPATH = foo/ ../bar/
-#    somerule: dependency.c
-#
-# Will find any of ./dependency.c, foo/dependency.c, or ../bar/dependency.c
-# We leverage this by flattening the list of SRCS to remove all path
-# information and adding all the paths from the SRCS to the VPATH, this means
-# we can write rules as-if all the SRCS were in a flat directory.
-#
-# The obvious pitfall here is what happens when multiple directories hold a
-# source file of the same name. However, both libnrf and mbed are set up to
-# use VPATH without running into that problem, which gives some pretty serious
-# hope that it won't be an issue in practice. The day is actually is a problem,
-# we can revisit this, but the only solution I can think of presently is
-# another layer of macros that generates the build rules for each path in SRCS,
-# which is a pretty hairy sounding proposition

-Tock aims to provide a build environment that is easy for application authors
-to integrate with. Check out the [examples](../examples) folder for
-sample applications. The Tock userland build system will automatically build
-with all of the correct flags and generate TABs for all supported Tock
-architectures.
-
-To leverage the Tock build system, you must:
-
-  1. Set `TOCK_USERLAND_BASE_DIR` to the path to the Tock userland.
-  2. `include $(TOCK_USERLAND_BASE_DIR)/AppMakefile.mk`.
-
-This `include` should be the _last_ line of the Makefile for most applications.
-
-In addition, you must specify the sources for your application:
-
-  - `C_SRCS`: A list of C files to compile.
-  - `CXX_SRCS`: A list of C++ files to compile.
-  - `AS_SRCS`: A list of assembly files to compile.
-  - `EXTERN_LIBS`: A list of directories for libraries [**compiled for Tock**](#compiling-libraries-for-tock).
-
-## Customizing the build
-
-### Flags
-
-The build system respects all of the standard `CFLAGS` (C only), `CXXFLAGS`
-(C++ only), `CPPFLAGS` (C and C++), `ASFLAGS` (asm only).
-
-By default, if you run something like `make CPPFLAGS=-Og`, make will use _only_
-the flags specified on the command line, but that means that Tock would lose all
-of its PIC-related flags. For that reason, Tock specifies all variables using
-make's [override directive](https://www.gnu.org/software/make/manual/html_node/Override-Directive.html).
-
-If you wish to set additional flags in your application Makefiles, you must also
-use `override`, or they will be ignored. That is, in your Makefile you must write
-`override CPPFLAGS += -Og` rather than just `CPPFLAGS += -Og`.
-
-If you are adding supplemental flags, you can put them anywhere. If you want to
-override Tock defaults, you'll need to place these _after_ the `include` directive
-in your Makefile.
-
-### Application configuration
-
-Several Tock-specific variables are also useful:
-
-  - `STACK_SIZE`: The minimum application stack size.
-  - `APP_HEAP_SIZE`: The minimum heap size for your application.
-  - `KERNEL_HEAP_SIZE`: The minimum grant size for your application.
-  - `PACKAGE_NAME`: The name for your application. Defaults to current folder.
-
-### Advanced
-
-If you want to see a verbose build that prints all the commands as run, simply
-run `make V=1`.
-
-The build system is broken across three files in the `libtock-c` repo:
-
-  - `Configuration.mk`: Sets most variables used.
-  - `Helpers.mk`: Generic rules and functions to support the build.
-  - `AppMakefile.mk`: Includes the above files and supplies build recipes.
-
-Applications wishing to define their own build rules can include only the
-`Configuration.mk` file to ensure all of the flags needed for Tock applications
-are included.
-
-## Compiling Libraries for Tock
-
-Libraries used by Tock need all of the same position-independent build flags as
-the final application. As Tock builds for all supported architectures by
-default, libraries should include images for each supported Tock architecture.
-
-### Let Tock do the work: TockLibrary.mk
-
-As the Tock build requirements (PIC, multiple architectures) are fairly complex,
-Tock provides a Makefile that will ensure everything is set up correctly and
-generate build rules for you. An example Makefile for `libexample`:
-
-> **libexample/Makefile**
-```make
-# Base definitions
-TOCK_USERLAND_BASE_DIR ?= ..
-LIBNAME := libexample
-
-# Careful! Must be a path that resolves correctly **from where make is invoked**
-#
-# If you are only ever compiling a standalone library, then it's fine to simply set
-$(LIBNAME)_DIR := .
-#
-# If you will be asking applications to rebuild this library (see the development
-# section below), then you'll need to ensure that this directory is still correct
-# when invoked from inside the application folder.
-#
-# Tock accomplishes this for in-tree libraries by having all makefiles
-# conditionally set the TOCK_USERLAND_BASE_DIR variable, so that there
-# is a common relative path everywhere.
-$(LIBNAME)_DIR := $(TOCK_USERLAND_BASE_DIR)/$(LIBNAME)
-
-# Grab all relevant source files. You can list them directly:
-$(LIBNAME)_SRCS :=                                      \
-    $($LIBNAME)_DIR)\libexample.c                       \
-    $($LIBNAME)_DIR)\libexample_helper.c                \
-    $($LIBNAME)_DIR)\subfolders_are_fine\otherfile.c
-
-# Or let make find them automatically:
-$(LIBNAME)_SRCS  :=                                     \
-    $(wildcard $($(LIBNAME)_DIR)/*.c)                   \
-    $(wildcard $($(LIBNAME)_DIR)/*.cxx)                 \ # or .cpp or .cc
-    $(wildcard $($(LIBNAME)_DIR)/*.s)
-
-include $(TOCK_USERLAND_BASE_DIR)/TockLibrary.mk
-```
-
-> __Note! `:=` is NOT the same as `=` in make. You must use `:=`.__
-
-### Developing (building) libraries concurrently with applications
-
-When developing a library, often it's useful to have the library rebuild automatically
-as part of the application build. Assuming that your library is using `TockLibrary.mk`,
-you can simply include the library's Makefile in your application's Makefile:
-
-```make
-include $(TOCK_USERLAND_BASE_DIR)/libexample/Makefile
-include ../../AppMakefile.mk
-```
-
-**Example:** We don't have an in-tree example of a single app that rebuilds
-a dedicated library in the Tock repository, but libtock is effectively treated
-this way as its Makefile is
-[included by AppMakefile.mk](../AppMakefile.mk#L17).
-
-### Pre-built libraries
-
-You can also include pre-built libraries, but recall that Tock supports multiple
-architectures, which means you must supply a pre-built image for each.
-
-Pre-built libraries must adhere to the following folder structure:
-
-```
-For the library "example"
-
-libexample/                <-- Folder name must match library name
-├── Makefile.app           <-- Optional additional rules to include when building apps
-├── build
-│   ├── cortex-m0          <-- Architecture names match gcc's -mcpu= flag
-│   │   └── libexample.a   <-- Library name must match folder name
-│   └── cortex-m4
-│       └── libexample.a   <-- Library name must match folder name
-│
-└── root_header.h          <-- The root directory will always be added to include path
-└── include                <-- An include/ directory will be added too if it exists
-    └── example.h
-```
-
-To include a pre-built library, add the _path_ to the root folder to the
-variable `EXTERN_LIBS` in your application Makefile, e.g.
-`EXTERN_LIBS += ../../libexample`.
-
-**Example:** In the Tock repository, lua53
-[ships a pre-built archive](../lua53/build/cortex-m4).
-
-### Manually including libraries
-
-To manually include an external library, add the library to each `LIBS_$(arch)`
-(i.e. `LIBS_cortex-m0`) variable. You can include header paths using the
-standard search mechanisms (i.e. `CPPFLAGS += -I<path>`).

-Overview
-========
-
-The bulk of Tock applications are written in C.
-
-## Entry Point
-
-Applications written in C that compile against libtock should define a `main`
-method with the following signature:
-
-```c
-int main(void);
-```
-
-Applications **should** return 0 from `main`. Returning non-zero is undefined and the
-behavior may change in future versions of `libtock`.
-Today, `main` is called from `_start` and includes an implicit `while()` loop:
-
-```c
-void _start(void* text_start, void* mem_start, void* memory_len, void* app_heap_break) {
-  main();
-  while (1) {
-    yield();
-  }
-}
-```
-
-Applications should set up a series of event subscriptions in their `main`
-method and then return.
-
-## Stack and Heap
-
-Applications can specify their required stack and heap sizes by defining the
-make variables `STACK_SIZE` and `APP_HEAP_SIZE`, which default to 2K and 1K
-respectively as of this writing.
-
-`libtock` will set the stack pointer during startup. To allow each application
-to set its own stack size, the linker script expects a symbol `STACK_SIZE` to
-be defined. The Tock build system will define this symbol during linking, using
-the make variable `STACK_SIZE`. A consequence of this technique is that
-changing the stack size requires that any source file also be touched so that
-the app will re-link.
-
-## Libraries
-
-Application code does not need to stand alone, libraries are available that can
-be utilized!
-
-### Newlib
-Application code written in C has access to most of the [C standard
-library](https://en.wikipedia.org/wiki/C_standard_library) which is implemented
-by [Newlib](https://en.wikipedia.org/wiki/Newlib). Newlib is focused on
-providing capabilities for embedded systems. It provides interfaces such as
-`printf`, `malloc`, and `memcpy`. Most, but not all features of the standard
-library are available to applications. The built configuration of Newlib is
-specified in [build.sh](../userland/newlib/build.sh).
-
-### libtock
-In order to interact with the Tock kernel, application code can use the
-`libtock` library. The majority of `libtock` are wrappers for interacting
-with Tock drivers through system calls. They provide the user a meaningful
-function name and arguments and then internally translate these into a
-`command`, `subscribe`, etc. Where it makes sense, the libraries also provide
-a synchronous interface to a driver using an internal callback and `yield_for`
-(example:
-[`tmp006_read_sync`](https://github.com/tock/tock/blob/master/userland/libtock/tmp006.c#L19))
-
-`libtock` also provides the startup code for applications
-([`crt0.c`](../userland/libtock/crt0.c)),
-an implementation for the system calls
-([`tock.c`](../userland/libtock/tock.c)),
-and pin definitions for platforms.
-
-### libc++
-Provides support for C++ apps. See `examples/cxx_hello`.
-
-### libnrfserialization
-Provides a pre-compiled library for using the Nordic nRF serialization library
-for writing BLE apps.
-
-### lua53
-Provides support for running a lua runtime as a Tock app. See
-`examples/lua-hello`.
-
-## Style & Format
-
-We try to keep a consistent style in mainline userland code. For C/C++, we use
-[uncrustify](https://github.com/uncrustify/uncrustify). High level:
-
-  - Two space character indents.
-  - Braces on the same line.
-  - Spaces around most operators.
-
-For details, see the [configuration](../userland/tools/uncrustify).
-
-Travis will automatically check formatting. You can format code locally using
-`make format`, or check the whole codebase with
-[format_all.sh](../userland/examples/format_all.sh). Formatting will overwrite
-files when it runs.

- *          from the application of this service is sent to the peer as Handle Value
- *          Notifications. This module demonstrates how to implement a custom GATT-based
- *          service and characteristics using the SoftDevice. The service
- *          is used by the application to send and receive ASCII text strings to and from the
- *          peer.
- *
- * @note The application must propagate SoftDevice events to the Nordic UART Service module
- *       by calling the ble_nus_on_ble_evt() function from the ble_stack_handler callback.

-Bluetooth Low Energy Advertisement App
-======================================
-
-An example application that demonstrates how the Bluetooth Low Energy API can be
-used to advertise data periodically that runs forever.
-
-The application does the following:
-  * Configures advertisement name to used in the advertisement
-  * Configures is the device shall be detected
-  * Configures the advertisement interval
-  * Configures list of UUIDs (generic service and temperature service)
-  * Configures temperature to a hard-coded value for demonstration purposes.

-SenSys 2018 Tutorial
-====================
-
-In November 2018 we hosted [a tutorial at SenSys](https://www.tockos.org/events/sensys2018),
-a preeminent conference for networking, sensors, and systems.
-
-The goal of this tutorial was to explore how multi-tenancy can cause problems
-(one buggy app draining system [energy] resources) and also provide solutions
-(via management that allow runtime monitoring and correction).
-The tutorial begins with a general overview of Tock and its programming
-environment, then considers application development and management, and finally
-digs into the 802.15.4 and UDP/IP capabilities in Tock.
-
-**If you are interested in doing this tutorial yourself, please
-`git checkout courses/2018-sensys` in both this repository and the Tock kernel.**

-UDP Button Press App
-====================
-
-Your client needs to keep track of sporadic events and record when those
-events occur by pressing the 'user' button on the Imix.
-
-This app is for platforms with an 802.15.4 radio.  It broadcasts button presses
-over the network, so they can be recorded at a central server.
-Currently, this app sends UDP packets using 6lowpan to a single neighbor with
-an IP address known ahead of time.
-
-## Running
-
-To run this app, simply place the IP address of the destination node in the `dst_addr` struct.
-Notably, until Tock has neighbor discovery implemented, you also have to configure
-the destination MAC address in the kernel (in `boards/imix/src/main.rs`).

-UDP Sensor App
-==============
-
-Your customer needs to periodically measure the environment around their board.
-
-This app is for platforms with hardware RNG support, environmental sensors, and
-an 802.15.4 radio. The app will broadcast periodic sensor readings over the
-network. Currently, it sends UDP packets using 6lowpan to a single neighbor
-with an IP address known ahead of time.  The contents of the payload (which are
-serialized to JSON) include:
-
-1. A random number, generated by the application accessing the underlying hardware RNG.
-
-2. Three sensor readings (temperature, relative humidity, and light).
-
-## Running
-
-To run this app, simply place the IP address of the destination node in the `dst_addr` struct.
-Notably, until Tock has neighbor discovery implemented, you also have to configure
-the destination MAC address in the kernel (in `boards/imix/src/main.rs`).
-
-### UDP Layer Reception Test
-
-The best way to test this app is by using the UDP reception app on another Imix.
-Program the kernel on two imixs. On one imix load this app to send packets. On
-the other imix load the `sensys_udp_rx` app found in
-`userland/examples/sensys_udp_rx`. You will want to set the
-`PRINT_STRING` macro to `1` for maximum visibility.
-
-If everything is working, you will see packets printed on the console.
-These lines contain the payload of the received UDP packet.

-Courses
-=======
-
-The Tock team periodically puts on courses teaching various aspects of Tock.
-
-Tock is a fast-moving project and courses are sometimes a bit specialized,
-which means the materials here may fall somewhat out of date over time.
-However they are still a good starting point.
-
-Each course README includes pointers to commits for both libtock and the Tock
-kernel at the time the course was taught. If you're interested in running
-through the course, please hop back in time to ensure everything works as
-planned. If find anything that does not work or is confusing, please feel free
-to [open an issue](https://github.com/tock/libtock-c/issues/new) or even better
-to [submit a pull request](https://github.com/tock/libtock-c/pulls/new) with a
-suggested fix.
-
-**Happy Hacking!**

-IPv6 Sensor App
-=============
-
-An example app for platforms with sensors and an 802.15.4 radio that broadcasts
-periodic sensor readings over the network. Currently, it sends UDP packets
-using 6lowpan to a single neighbor with an IP address known ahead of time.
-
-## Running
-
-This application should be tested using the `udp_rx` app in `examples/tests/udp/udp_rx`.
-Flash one Imix with this application, and flash a second Imix with `udp_rx`. If both
-apps are working correctly, the second Imix will blink its user LED every
-time an app is received, and will print the payload of each received packet
-to the console. If you wish to use this app to send to a board with a different
-address than the one hardcoded in this application, change the destination IPv6 address
-to match the source IPv6 address of your intended receiver. Note that in order
-to send to a different receiver you must also change the destination MAC address,
-which is currently configured in the kernel (in `boards/imix/src/main.rs`)
