Due to the midi interface being difficult/impossible to increment on
values of 1 because it has 7-bits of granularity, this commit moves all
the bitfields for configuring segment options left by one which
guarantees that every option has 2 values next to each other.
This allows midi controllers to more easily select an individual segment
option for 2D arrays.
Before this commit it was only possible to control mirror and reverse on
a 1d segment. All of the other options for 2d effects could not be set
and thus they would be kept disabled.
This commit replaces the Effect Option dmx channel with a bitfield which
allows for each segment option to be individually toggled depending on
which bit is set in the field. Backwards compatibility has been
maintained with existing 1d segment options.
Upgrade the MPU6050 usermod to provide configuration settings for
interrupt pin selection and calibration, a polled mode, and data
output for consumption by other usermods.
Add JSONBufferGuard, an RAII lock guard class for JSONBufferLock
analogous to std::lock_guard. This permits binding the guard to a scope,
such as an object life cycle or function body, guaranteeing that the
lock will be released when the scope exits.
Allows for "pixel perfect" liveview instead of diffused view, to better match what's shown at https://kno.wled.ge/features/effects/. This will make it easier to see what the LEDs are doing, although it may not be as accurate a representation for installations with diffused LEDs. Includes fallback to CSS gradient method for browsers that don't support canvas.
sunset = 0 is a valid result, as the function result is in UTC and not local time .
Example: local time is UTC-8, local sunrise = 08:00am => getSunriseUTC() = 0.
So we cannot use "0" for "invalid". Using UINT16_MAX resolves the problem, and even allows to simplify calculateSunriseAndSunset() a bit.
