- created possiblity to use PWM, PPM input also on both LEFT and RIGHT cable (RIGHT cable is 5V tolerant)
- updated UART: disabled the Rx errors to avoid DMA stop and additional need to manage the UART error handler
- added Button support LEFT/RIGHT
- PWM Variant should now support that the PWM for the 2 channels (steering, throttle) can happen:
• in the same time (ussually the case if Servo library from Arduino is used)
•or offseted (ussually if commercial RC PWM received is used)
- made the PWM timeout for the 2 channels independent to be able to use only one channel if desired.
- 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
