# HASP - Open Hardware edition

This project is a re-implementation of the popular HASwitchPlate sketch created by aderusha.
The [original HASwitchPlate][1] project uses a Wemos D1 mini and requires a Nextion/TJC HMI display.
This rewrite removes the Nextion/TJC requirement by using the [Littlev Graphics Library][2] on the MCU to drive a cheap commodity display.

This version also adds ESP32 support to take advantage of the additional hardware capabilities.

## Cloning

Make sure to add the `--recursive` parameter when cloning the project. Otherwise git will not download the required submodules in the `/lib` subdirectory.

```bash
git clone --recursive https://github.com/fvanroie/hasp-lvgl
```

If you already cloned hasp-lvgl without the submodules, you can fetch the submodules seperately using:

```bash
git submodule update --init --recursive
```
