hi, I would like to use pwm to output the 1HZ waveform to drive the motor, but when I set the frequency to be 1HZ, I can not find the device and cause 51822 to reset. This is my code:
Motor_Pwm_Init(1000000,1,1);
Motor_Duty_Set(50,50);
void Motor_Pwm_Init(uint32_t freq,uint32_t MotorLeft_Polarity,uint32_t MotorRight_Polarity)
{
uint32_t err_code;
app_pwm_disable(&PWM1);
app_pwm_uninit(&PWM1);
app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_2CH(freq,MOTOR_LEFT_PIN,MOTOT_RIGHT_PIN); //set pwm frequency
pwm1_cfg.pin_polarity[0] = MotorLeft_Polarity; //Polarity of active state on pin.
pwm1_cfg.pin_polarity[1] = MotorRight_Polarity;
err_code = app_pwm_init(&PWM1,&pwm1_cfg,NULL); // Init the PWM
APP_ERROR_CHECK(err_code);
app_pwm_enable(&PWM1);
}
uint8_t Motor_Duty_Set(uint32_t DutyLeft,uint32_t DutyRight)
{
uint8_t TimeOut = 0;
wdt_feed();
while (app_pwm_channel_duty_set(&PWM1,(uint8_t) 0, DutyLeft) == NRF_ERROR_BUSY)
{
}
}
