EmanuelFeru dcdac4f6db Updated PWM variant
- fixed the setScopeChannel for PWM, to calibrate properly the limits
- improved the scaling
2020-07-20 19:36:24 +02:00
EmanuelFeru f2d86f3b30 Added functionality: Electric Brake, Standstill hold
- 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.

EmanuelFeru 22984a7fd6 Fixed PPM, PWM timeout
- 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

EmanuelFeru 17e127a8b7 PWM/PPM Left/Right, UART update
- 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
2020-06-25 20:17:55 +02:00
EmanuelFeru ac90ed1b6b Fixed initial condition bug
- the initial condition for the Battery and Board temperature was wrongly set
- the filter is fixdt(1,32,16), so the shift should be by 16 bits.

EmanuelFeru 72e6b30033 UART with sideboards works + major refactoring
► 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

EmanuelFeru b4b23bbe9b Implemented HOVERCAR variant
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

EmanuelFeru 31d42b4a17 Major improvements
- 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
