STM32F103R6的Keil和Protues仿真-点亮LED灯

1、效果

1.1、低电平点亮

1.2、高电平点亮

• 注意高电平点亮只是仿真，真实还是使用低电平点亮。需要设置LED点亮的电流，否则LED不会亮。
  

2、代码

2.1、Keil

• 高电平点亮
  • https://gitee.com/xiaolixi/l-stm32/tree/master/STM32ProjectKeil/2-1tem-ld-high

#include "stm32f10x.h"                  // Device header

int main(void)
{
	RCC->APB2ENR = 0x00000010; # 开启时钟
	
	GPIOC->CRH = 0x00300000; # 推挽输出
	GPIOC->ODR = 0x00002000; # 高电平
	while(1) {
		
	}
}

• 低电平点亮
  • https://gitee.com/xiaolixi/l-stm32/tree/master/STM32ProjectKeil/2-1tem-ld-low

#include "stm32f10x.h"                  // Device header

int main(void)
{
	RCC->APB2ENR = 0x00000010;
	
	GPIOC->CRH = 0x00300000;
	GPIOC->ODR = 0x00000000; # 输出低电平
	while(1) {
		
	}
}

2.2、protues
