Hi I know this is not a place probabbly to rise question like this but cant find answer nowhere.... Basically I want two PWM outputs to be shifted with some dead-time between.. but i just cant set two pwm channels to output at same time. Here is my arduino script for STM32F103CT

define pin PA0

define pin2 PA1

define POT_IN PA4

int PotValue4; int VB; int dutyCycle;

//TIM_TypeDef Instance = TIM1; //TIM_TypeDef Instance2 = TIM2; TIM_TypeDef Instance = (TIM_TypeDef )pinmap_peripheral(digitalPinToPinName(pin), PinMap_PWM); uint32_t channel = STM_PIN_CHANNEL(pinmap_function(digitalPinToPinName(pin), PinMap_PWM)); HardwareTimer *MyTim = new HardwareTimer(Instance);

TIM_TypeDef Instance2 = (TIM_TypeDef )pinmap_peripheral(digitalPinToPinName(pin2), PinMap_PWM); uint32_t channel2 = STM_PIN_CHANNEL(pinmap_function(digitalPinToPinName(pin2), PinMap_PWM)); HardwareTimer *MyTim2 = new HardwareTimer(Instance2);

void Update_IT_callback(void) { //float VB = analogRead(POT_IN); //MyTim->setOverflow(100000, MICROSEC_FORMAT); //Serial.println("UITC"); } void Update_IT_callback2(void) { //float VB = analogRead(POT_IN); //MyTim->setOverflow(100000, MICROSEC_FORMAT); //Serial.println("UITC"); } void Compare_IT_callback(void) { VB = analogRead(POT_IN); Serial.println(VB); dutyCycle = map(VB, 0, 900, 50, 10); //Serial.println(dutyCycle); //MyTim->setOverflow(dutyCycle, MICROSEC_FORMAT); MyTim->setCaptureCompare(channel, dutyCycle, PERCENT_COMPARE_FORMAT); //Serial.println("CITC"); }

void Compare_IT_callback2(void) { VB = analogRead(POT_IN); Serial.println(VB); dutyCycle = map(VB, 0, 900, 50, 10); //Serial.println(dutyCycle); //MyTim->setOverflow(dutyCycle, MICROSEC_FORMAT); MyTim->setCaptureCompare(channel, dutyCycle, PERCENT_COMPARE_FORMAT); //Serial.println("CITC"); } void setup() { while(!Serial); Serial.begin(115200);

delay(2000); Serial.println("STM32F103C blink and serial test");

pinMode(POT_IN, INPUT); PotValue4 = analogRead(PA4);

MyTim->setMode(channel, TIMER_OUTPUT_COMPARE_PWM1, pin); MyTim->setOverflow(100000, HERTZ_FORMAT); // 100000 microseconds = 100 milliseconds MyTim->setCaptureCompare(channel, 50, PERCENT_COMPARE_FORMAT); // 50% //MyTim->attachInterrupt(Update_IT_callback); MyTim->attachInterrupt(channel, Compare_IT_callback);

MyTim2->setMode(channel2, TIMER_OUTPUT_COMPARE_PWM1, pin2); MyTim2->setOverflow(100000, HERTZ_FORMAT); // 100000 microseconds = 100 milliseconds MyTim2->setCaptureCompare(channel2, 50, PERCENT_COMPARE_FORMAT); // 50% //MyTim2->attachInterrupt(Update_IT_callback2); MyTim2->attachInterrupt(channel, Compare_IT_callback2);

MyTim->resume();

}

void loop() { //Serial.println(VB); }
