Hi

How to change arduino uno code to STM32F103

void setup(){ pinMode(9,OUTPUT); pinMode(10,OUTPUT); TCCR1B = (1<<WGM13)|(1<<CS10);  TCCR1A = (1<<COM1A1)|(1<<COM1B1)|(1<<COM1B0);  TIMSK1 = 1<<TOIE1; ICR1=511;  OCR1B=0; }   ISR (TIMER1_OVF_vect) { static uint8_t  n=0; OCR1A =  OCR1B= sine_wave[n]; n++; }  void loop(){ }

You'd be better starting with what you're trying to achieve, and re-implement.

Set up clocks and pins

Program periodicity of TIM

Set up circular DMA to point to Sine Wave table, and configure TIM/DMA to update pulse width at each period update.

Don't look at individual lines of code but blocks of code and ask yourself what those blocks are trying to do.

After that implement the functionality on your new target.

Set up circular DMA to point to Sine Wave table - 

How to do that some links will help.

Similar code for STM32

HardwareTimer pwmtimer2(2); void setup() { pinMode(PA3, PWM); //Pin mode selected pwmtimer2.pause(); pwmtimer2.setPrescaleFactor(1); // Prescaler setup pwmtimer2.setOverflow(10000-1); // 256 ? pwmtimer2.setCompare(TIMER_CH4, 5000); // ? pwmtimer2.refresh(); pwmtimer2.resume(); } void loop() { } // How to tell to produce sine ?
