stm32f030例程led

您可以参考以下代码实现stm32f030的LED控制：

#include "stm32f0xx.h"

void delay(uint32_t count) {
    for (uint32_t i = 0; i < count; i++);
}

int main(void) {
    RCC->AHBENR |= RCC_AHBENR_GPIOCEN; // 使能GPIOC时钟
    GPIOC->MODER |= GPIO_MODER_MODER8_0; // PC8设置为输出模式

    while (1) {
        GPIOC->BSRR = GPIO_BSRR_BS_8; // PC8输出高电平
        delay(1000000);
        GPIOC->BRR = GPIO_BRR_BR_8; // PC8输出低电平
        delay(1000000);
    }
}
