In Cruise Control (CC), the button can bounce. The beep delay is increased from 100ms to 200ms to prevent button bouncing and continuous activation/deactivation of CC.
- 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
- For TORQUE mode, by enabling `ELECTRIC_BRAKE_ENABLE` in `config.h`, the freewheeling amount can be adjusted using the `ELECTRIC_BRAKE_MAX` parameter.
- For VOLTAGE and TORQUE mode, the standstill hold functionality can be forced by enabling `STANDSTILL_HOLD_ENABLE` in `config.h`.
Known (minor) issue: There is a small "tick" noise when Stanstill is engaged/disengaged, due to the switching to SPEED mode. To be solved by an improved mode switching strategy in the future.
- 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
- 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
- the UART communication is improved based on UART Idle line detection interrupt
- an Rx ring buffer is used to manage the UART incoming data
- both Tx and Rx are efficiently handled using DMA
#45#64#65
Other:
- minor visual improvements
Apparently, the UART data Rx/Tx is quite unreliable (especially under motor load) leading to very often out-of-sync issues. This change allows to reset the DMA more often, leading to a faster re-sync of the UART transmission and thus avoiding UART timeout.
► 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
