代码演示,
- #include "stm32f10x.h" // Device header
- #include "Delay.h"
- int main(void)
- {
- RCC->APB2ENR = 0x00000004; //打开GPIOA使能
- GPIOA->CRH = 0x00003000; //配置PA11引脚为通用推挽输出模式
- while(1)
- {
- GPIOA->ODR = 0x00000800; //PA11输出高电平
- Delay_ms(1000);
- GPIOA->ODR = 0x00000000; //PA11输出低电平
- Delay_ms(1000);
- }
- }
