stm32f103r6写一个按键控制led的代码

好的，以下是一个简单的stm32f103r6按键控制led的代码：

#include "stm32f10x.h"

int main(void)
{
    // Enable GPIOC and GPIOA clock
    RCC->APB2ENR |= RCC_APB2ENR_IOPCEN;
    RCC->APB2ENR |= RCC_APB2ENR_IOPAEN;

    // Set PC13 as output (LED)
    GPIOC->CRH &= ~(GPIO_CRH_CNF13 | GPIO_CRH_MODE13);
    GPIOC->CRH |= GPIO_CRH_MODE13_0;

    // Set PA0 as input (button)
    GPIOA->CRL &= ~(GPIO_CRL_CNF0 | GPIO_CRL_MODE0);

    while (1)
    {
        if (GPIOA->IDR & GPIO_IDR_IDR0)
        {
            // Button is not pressed, turn off LED
            GPIOC->BSRR |= GPIO_BSRR_BR13;
        }
        else
        {
            // Button is pressed, turn on LED
            GPIOC->BSRR |= GPIO_BSRR_BS13;
        }
    }
}

希望能对你有所帮助！
