Hi. Could You help me to understand somethink. In STM32 like STM32F103c8... there is a clock signal called RCC_APB2Periph_AFIO. When should be turned on this signal
The RCC feeds the external clock of the Cortex System Timer (SysTick) with the AHB clock (HCLK) divided by 8. The SysTick can work either with this clock or with the Cortex clock (HCLK), configurable in the SysTick control and status register. ...
#include “stm32f10x_rcc.h” GPIO_InitTypeDef GPIO_InitStructure; int i; #define LED_PORT GPIOB Void binky(); Void main() { Void binky(); } void binky(void) { RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE); //enable the PORTB pins// ...
