stm32点亮LED 测试代码及目录结构

.

main.c - 使用PB12, PB13, PB14, PB15, PB5, PB6, PB7 这七个PB口点亮LED. 注意PB3和PB4是特殊口, 直接调用无效.

#include "delay.h"
#include "stm32f10x.h"

int main(void) {
    u16 i;
    u8 j;
    uint16_t gpios[] = {GPIO_Pin_12, GPIO_Pin_13, GPIO_Pin_14, GPIO_Pin_15, GPIO_Pin_5, GPIO_Pin_6, GPIO_Pin_7};
    GPIO_InitTypeDef  GPIO_InitStructure;
    delay_init(); //延时函数初始化      
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE); /使能PB端口时钟
    
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_12|GPIO_Pin_13|GPIO_Pin_14|GPIO_Pin_15|GPIO_Pin_5|GPIO_Pin_6|GPIO_Pin_7;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; //推挽输出
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; //IO口速度为50MHz
    GPIO_Init(GPIOB, &GPIO_InitStructure);  //根据设定参数初始化GPIOB.5

    while(1) {
        i = (i+20) % 500;
        for (j = 0; j < 6; j++) {
            GPIO_SetBits(GPIOB, gpios[j]);
            delay_ms(i);
            GPIO_ResetBits(GPIOB,gpios[j]);
        }
        for (j = 6; j > 0; j--) {
            GPIO_SetBits(GPIOB, gpios[j]);
            delay_ms(i);
            GPIO_ResetBits(GPIOB,gpios[j]);
        }
    }
