i have written a led blinking program with as per my knowledge but i couldn't reach output so guys who can clear that? MCU- STM32f401 clock input -25MHz External clock output -80 MHz with pll configuration
#include "stm32f4xx.h"#define PLLM 25#define PLLN 320#define PLLP 1//divide 4void SysConfigure(){ RCC->CR|=RCC_CR_HSEON;//External Crystal Oscillator while(!(RCC->CR & RCC_CR_HSERDY));// External Crystal oscillator status flag checking ...
