Hello @cedric H ,
thanks for your response.
I actually tried the FOC algo aswell. At least here the code that got generated could be build successfully.
After deploying the code to the ESC, I connected the ESC to a power supply and I am trying to control the motor via a PWM signal from a nucleo board.
I wrote some code that changed the duty cycle of the PWM signal from unarmed to armed. I hear a beep noise (I assume its the sound that tells that the motor is ready) but there is no movement on the motor.
Here is the relevant code, that I run on the Nucleo board: I measured the PWM Signal with a logical analyzer and confirmed the period/dutyCycles.
void setDutyCycleTIM20(uint8_t dutyCycle){
// check if param dutyCycle is valid
if (dutyCycle < 0 || dutyCycle > 100){
// TODO insert error message
return;
}
// set new dutyCycle and map 0 ... 100 to 1060 ... 1860
__HAL_TIM_SET_COMPARE(&htim20, TIM_CHANNEL_2, (dutyCycle*800)/100.0 + 1060);
}
...
int main(void)
{
...
while (1) {
/* USER CODE END WHILE */
setDutyCycleTIM20(0);
HAL_Delay(1000);
setDutyCycleTIM20(5);
HAL_Delay(5000);
setDutyCycleTIM20(10);
HAL_Delay(5000);
setDutyCycleTIM20(20);
HAL_Delay(5000);
__HAL_TIM_SET_COMPARE(&htim20, TIM_CHANNEL_2, 800);
HAL_Delay(1000);
/* USER CODE BEGIN 3 */
}
}
I am thankful for any tips.
Best
Batu
