找个GPIO的程序认真学习下，相信你应该能搞定 

谢谢提醒呢，我会的哈，我会努力的呢。

同意楼上的方案..
另一种方案是 开一个定时器做计时使用,主循环中查看变量
int timerled = 0;
int ledCount = 1;//1代表灯亮 0代表等灭
int i = 0;
char ledoff = 0;
int timerkey = 0;

while(1)
{
if(!ledoff)
{
ledCount = 1;
for(i = 0;i < 16;i++)
{
GPIOA->ODR = ledCount;
ledCount

建议楼主下载stm32 的GPIO例程，结合相关技术文档仔细耐心研究，这样针对性的学习相信会有很大收获

先看看GPIO,然后看定时器，接着是外中断，建议先接触51单片机，这样上手快。

青檬

你需要了解 GPIO口的使用及EXTI,看下例程，相信你能搞定！
