标题: STM8L0单片机+L76C GPS+DMA+串口源程序
本程序用于太阳能同步雾灯，可通过DMA+USART1接收移远GPS模块（L76C）实现同步闪烁。

单片机源程序如下:
  1. #include "stm8l15x.h"
  2. #include "led.h"
  3. #include "lamp.h"
  4. #include "adc.h"
  5. #include "usart1.h"
  6. #include "timer.h"
  7. #include "switch.h"
  8. #include "gps.h"
  9. #include "dma.h"

  11. void main()
  12. {
  13.   disableInterrupts();   //关闭系统总中断
  14.   CLK_SYSCLKDivConfig(CLK_SYSCLKDiv_1); //内部时钟为1分频 = 16Mhz
  15.   
  16.   LEDInit();
  17.   LAMPInit();
  18.   SWITCHInit();
  19.   ADCInit();
  20.   USART1Init(9600);
  21.   DMAInit();
  22.   GPSInit();
  23.   TIM4_Init();   //调用定时器4初始化函数
  24.   enableInterrupts();   //使能系统总中断

  26.   while(1)
  27.   {  
  28.     AdcHandler(); //AD采样
  29.     GPSHandler(); //GPS数据解析
  30.   }   
  31. }
复制代码
