EmanuelFeru b76e8ee466 Update BLDC controller
- 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

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

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

EmanuelFeru 526cee4c0f Lowered pwm_margin by 10
- to avoid virbation at maximum PWM = 1000, due to reduced Phase current accuracy, the pwm margin is lowered by 10.
Fixed #69

EmanuelFeru 5f2eb196af Improved UART error recovery
- In case of an Rx error instead of stopping the complete UART, only the Rx DMA is aborted and restarted.

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.

2020-06-13 10:57:54 +02:00
EmanuelFeru 8ddfc82882 Updated PWM Variant
- 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.

EmanuelFeru b95307f260 Update control.c
- 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.

EmanuelFeru 34c6e4d610 Improved UART Timeout
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.

EmanuelFeru 736f2b9419 Minor updates
- 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.

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
