Hi Sir,
I am new with B-G431B-ESC1 to run SimpleFOC.
My testing environment is PlatformIO.
I reference B-G431B-ESC1 code from Github Arduino-FOC-dev
My platformio.ini is below
[env:disco_b_g431b_esc1]
platform = ststm32
board = disco_b_g431b_esc1
framework = Arduino
monitor_speed = 115200
lib_deps=
SPI
Wire
The problem I met is,
I can compile and program, but I found there are no PWM outputs from G431 MCU.
Here is the driver definition in my code.
BLDCDriver6PWM driver = BLDCDriver6PWM(A_PHASE_UH, A_PHASE_UL, A_PHASE_VH, A_PHASE_VL, A_PHASE_WH, A_PHASE_WL);
I can find A_PHASE_UH, A_PHASE_UL, A_PHASE_VH, A_PHASE_VL, A_PHASE_WH, A_PHASE_WL define, and aligned with B-G431B-ESC1 sch.
But after I programed the code, it does not work (even I choice motor.controller = MotionControlType::velocity_openloop;)
I donāt know why.
here is my code for your information.

BLDCMotor motor = BLDCMotor(7);
BLDCDriver6PWM driver = BLDCDriver6PWM(A_PHASE_UH, A_PHASE_UL, A_PHASE_VH, A_PHASE_VL, A_PHASE_WH, A_PHASE_WL);
LowsideCurrentSense currentSense = LowsideCurrentSense(0.003, -64.0/7.0, A_OP1_OUT, A_OP2_OUT, A_OP3_OUT);

// set motion control loop to be used
motor.controller = MotionControlType::velocity_openloop;

motor.PID_velocity.I = 20;

// jerk control using voltage voltage ramp

// use monitoring with serial
Serial.begin(115200);
// comment out if not needed
motor.useMonitoring(Serial);
motor.monitor_downsample = 100; // setting sample rate, can up to 100+
motor.monitor_variables = _MON_TARGET | _MON_VEL | _MON_ANGLE;
// initialize motor
motor.init();
// align encoder and start FOC
// motor.initFOC();
motor.target = 1;
// add target command T
command.add(āTā, doTarget, ātarget angleā);
Serial.println(F(āMotor ready.ā));
Serial.println(F(āSet the target angle using serial terminal:ā));
_delay(1000);
}
void loop() {
// main FOC algorithm function
//motor.loopFOC();
// Motion control function
//motor.move();
// function intended to be used with serial plotter to monitor motor variables
// significantly slowing the execution down!!!
motor.monitor();
// user communication
command.run();
// Debug encoder, done, everything is correct
// iterative function updating the sensor internal variables
// it is usually called in motor.loopFOC()
// not doing much for the encoder though
// encoder.update();
// display the angle and the angular velocity to the terminal
// Serial.print(encoder.getAngle());
// Serial.print(ā\tā);
// Serial.println(encoder.getVelocity());
}
Added two pictures here, the motor is ok, my self driver board can run the motor well.
