- removed the `PWM_signal_Correct(..)` function, because it is already existing here 34c6e4d610/Src/util.c (L844-L862)
- added (void) to the functions
- limited `pwm_timeout` to 500 instead of 0, ottherwise the timeout won't work properly, because it will will reset every time.
► the mainboard can now send and receive Serial data from the sideboards
► heavy refactored the `main.c`. It was becoming too large to manage... Therefore, `util.c` and `util.h` was created
► added new functionality for `VARIANT_HOVERCAR` and variants with `CONTROL_ADC` in general:
- ADC limits auto-calibration mode (long press of the power button) - calibration will not be lost at power-off
- Max Current and Max Speed adjustment mode (long press followed by a short press of the power button) - calibration will not be lost at power-off
- added one sideboard functionality:
- LEDs are used to display battery level, Motor Enable, Errors, Reverse driving, Braking.
- Photo sensors are used as push buttons: One for changing Control Mode, One for Activating/Deactivating the Field Weakening on the fly
