- updated ReadMe: added higher resolution mainboard picture, added links with projects, online compiler, Telegram link
- setup.c : fixed the Charger GPIO pin to PULLUP, otherwise the Charger won't be recognized when connected
- config.h : increased the default ADC protection Timeout from 30 to 100 for more robustness.
► 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
- added condition in config.h to either take setting from platform.ini or config.h
- homogenized default_envs naming; all variants now have VARIANT_ as prefix
- added nunchuck variant in platform.ini and config.h
- added PPM variant in platform.ini and config.h
- README: added jan's nunchuck breakout board repo
Major:
- created HOVERCAR variant (selectable via platformio.ini) for driving via 2 pedals: Brake (on cmd1) and Throttle (on cmd2)
- implemented "Double tapping" on Brake pedal to engage Reverse driving
- implemented that Brake pedal stops the vehicle but does not go to Reverse, to prevend unintended Reverse driving
- implemented ADC Protection when GND and Vcc wire are disconnected. The functionality can be enabled/disabled via #define ADC_PROTECT_ENA
- updated error handling: in case of major error the motors will be disabled for improved safety
Minor:
- fixed bug on low-pass filter for not reaching exact "0" value
- calibrated the ADC Battery voltage reading
- other minor visual updates
Sinusoidal Control Type is now available is this branch. To select it go in config.h and change CTRL_TYP_SEL to 1. By default FOC control type is selcted.
Note: SPEED and TORQUE modes are not available for Sinusoidal control type.
