Output Compare not working for STM32F407 Discovery Board

KUMAR BURRE over 5 years ago

Hi,

I am working on STM32F407 Discovery board. I am trying to use output compare mode in stm32 for led toggle. Here is the code I have written

#include "stm32f4xx.h" //Header File for STM32F4 device

int main(void)
{
   //
   RCC->AHB1ENR |=1;          //Enable GPIOA Port Clock
   GPIOA->MODER|= 0X800 ;      //Configure I/O direction for PA5 as Alternatefunction   0100 0000 0000
   GPIOA->AFR[0]|=0X00100000;
   RCC->APB1ENR|=1;
   TIM2->PSC=1600-1;
   TIM2->ARR=10000-1;
   TIM2->CCMR1=0X30;
   TIM2->CCR1=0;
   TIM2->CCER|=1;
   TIM2->CNT=0;
   TIM2->CR1=1;

   while(1)
   {


   }

   return 0;
}

But, the code is not working. Can any one help me if there is any error in this code.
