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
- 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.
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.
- 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.
