请大家帮忙给写一个stm32的频闪灯程序吧，就是控制灯快速的闪烁2下之后过个30秒在闪烁2次频闪的效果，如果不用单片机用电路也可以请大家帮忙谢谢。

1块钱的8脚stm8s003，程序百度一下5分钟也能搞定了

这应该是最简单的点灯程序了。单片机如果不干别的事，直接软件延时，用cube配置好管脚，几行代码就行了。如果单片机还要干别的事，开一个定时器，定时到30秒闪灯就好。更高级的用RTOS。

上STM32就浪费了，8脚的STC15F104就够了。不用单片机的话就用两个NE555，不过电路太复杂了，还要调参数。8脚的STC不香么。

#include <AT89X51.h>

sbit LED = P3^3;       //LED低电平点亮

//延时约1ms
void Delay(unsigned int t)
{
unsigned int a,b;
for (a=0; a<t; a++)
      for (b=0; b<123; b++)
         ;
}

void main(void)
{
LED = 1;
while(1)
{
      Delay(30000); //延时30S

      LED = 0;       //亮0.3S
      Delay(300);

      LED = 1;       //灭0.3S
      Delay(300);

      LED = 0;       //亮0.3S
      Delay(300);

      LED = 1;       //灭0.3S
      Delay(300);
}
}

用6脚的OTP单片机，成本2-3毛，不更爽？

顺便说一下，楼上没有指明STC15F104的工作频率。
