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
Now it is easy to select between different variant builds via platformio.ini. Currently, 3 variants can be selected:
VARIANT_ADC
VARIANT_USART3
TRANSPOTTER
Note: For any particular needs, you can still change config.h according to your needs.
- reduced FOC computational complexity by up to 20%, from 85% (old) to 65% (new)
- updated Field Weakening by allowing more freedom set-up: field weakening blended in the input fully, partially blended, or fully outside the input range
- major improvemets on current and speed limitations. It allows seemless limitation protection -> very happy with the result
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.
The firmware allows now to set higher currents than 15 A/motor.
NOTE: You can change this limit at your own risk. I do not take any responsability if your boards gets damaged.
