- added possbility to switch the Control mode while motor is spinning. NOT yet checked how motors behaves when swiching is triggered!
- added Cruise Control functionality: activated by button1 to GND (Blue Left or Right cable depending on selection). Functionality NOT yet tested in practice!
- extended Phase current measurements z_selPhaCurMeasABC : {iA,iB} = 0; {iB,iC} = 1; {iA,iC} = 2
- added interface for external motor angle measurement from as sensor, e.g., encoder. The selection can be done via b_angleMeasEna: 0 = Estimated (default), 1 = Measured.
- update the Field weakening Lo and Hi to fully blended.
- minor improvements:
- Buttons initialization
- lowered ADC margins in auto-calibration
- commented out ADC_SAMPLETIME_239CYCLES_5, reported to give some issues when Hall sensor ADC input is used
- fixed the general timeout handling: there is no need to disable the MOSFETs timer because it will confuse the BLDC_controller, making him consider the timeout as a false MOSFET defective error.
- renamed `timeout` to `timeoutCnt` for consistency and to ease the search
#61
► 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
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
- 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
Major:
- Issue #3: added raw ADC1, ADC2 values to the setScopeChannel
- Issue #4: added functionality for joystick control. Middle resting potis are now supported (by default it is enabled)
- Issue #6: implemented that board does not power-off after a software reset due to flashing
- added Rate constraints for Input target for smoother response
Minor:
- added 2 beep sound when motors get enabled
- minor bugfixes
The follwing were converted to fixed-point
- battery voltage
- board temperature
- filters for steer and speed
- mixer calculation
Starting from this moment, the firmware is floating point free, meaning it runs more efficiently.
