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:)RE:请问怎样用STM32做一个流水灯实验程序怎么写?谢谢!【悬赏问答】
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。回复:请问怎样用STM32做一个流水灯实验程序怎么写?谢谢!【悬赏问答】
你需要了解 GPIO口的使用及EXTI,看下例程,相信你能搞定!RE:请问怎样用STM32做一个流水灯实验程序怎么写?谢谢!【悬赏问答】
