先上个代码- #include "stm8s_conf.h"
- int main( void )
- {
- CLK->CKDIVR &=~((1<<4)|(1<<3));//配置时钟为内部RC，16M
- sim();//关总中断
- GPIOD->DDR |=(1<<2);//PD2为输出
- GPIOD->CR1 |=(1<<2);//推挽
- GPIOD->CR2 |=(1<<2);//输出速率为10M
- GPIOA->DDR |=(1<<3);//PA3为输出
- GPIOA->CR1 |=(1<<3);//推挽
- GPIOA->CR2 |=(1<<3);//输出速率为10M
- GPIOA->ODR |=(1<<3);//PA3为高
- rim();//开总中断
- GPIOD->DDR &=~(1<<2);//PD2为输入
- GPIOD->CR1 |=(1<<2);//上啦
- GPIOD->CR2 &=~(1<<2);//引脚中断失能
- GPIOA->ODR &=~(1<<3);//PA3为低
- while(1)
- {
- }
- }
