板子已经焊接了一部分，为了测试一下焊接得有没有问题，先做了一个流水灯实验：

#include<STC12C5A60S2.H> //头文件

/*********************************************************************************************
函数名：毫秒级CPU延时函数
调用：DELAY_MS (?);
参数：1~65535（参数不可为0）
返回值：无
结果：占用CPU方式延时与参数数值相同的毫秒时间
备注：应用于1T单片机时i<600，应用于12T单片机时i<125
/*********************************************************************************************/
void DELAY_MS (unsigned int a){
unsigned int i;
while( a-- != 0){
for(i = 0; i < 600; i++);
}
}
/*********************************************************************************************/

/*********************************************************************************************/
void main (void){ //主程序

  for(i=0;i<8;i++){ //低位到高位流动（P1.0~P1.7）
   P1 = 1<<i;
   DELAY_MS(100);
      }
  P1=0x00;

  for(i=0;i<8;i++){ //高位到低位流动（P1.7~P1.0）
   P1 = 1<<7-i;
   DELAY_MS(100);
  }
  P1=0x00;

ATmega8515这个没用个，但是我看了一下，管脚好像是兼容的，兼容的话就可以的

从论坛里哪位网友哪儿买来的套件中LED点阵屏与PCB上的尺寸不符，不能直接在实验板上使用，而再单购买一块点阵屏又不合算，所以只好通过一块洞洞板对其进行转接，经过一番功夫做好就成了下面见个样子：

装到DIY实验板上的样子：

LED点阵屏测试：

原程序：
#include <STC12C5A60S2.H> //STC头文件

#define LOGOSPEED 150 //设置开机LOGO部分的流动速度
#define DELAY 12 //设置每一个点显示的时间长度（1~20）

sbit led_H2 =P0 ^ 1; //设置LED点阵屏连接的I/O口
sbit led_H3 =P0 ^ 2; //设置LED点阵屏连接的I/O口
sbit led_H4 =P0 ^ 3; //设置LED点阵屏连接的I/O口
sbit led_H5 =P0 ^ 4; //设置LED点阵屏连接的I/O口
sbit led_H6 =P0 ^ 5; //设置LED点阵屏连接的I/O口
sbit led_H7 =P0 ^ 6; //设置LED点阵屏连接的I/O口
sbit led_H8 =P0 ^ 7; //设置LED点阵屏连接的I/O口

sbit led_L1 =P2 ^ 0; //设置LED点阵屏连接的I/O口
sbit led_L2 =P2 ^ 1; //设置LED点阵屏连接的I/O口
sbit led_L3 =P2 ^ 2; //设置LED点阵屏连接的I/O口
sbit led_L4 =P2 ^ 3; //设置LED点阵屏连接的I/O口
sbit led_L5 =P2 ^ 4; //设置LED点阵屏连接的I/O口
sbit led_L6 =P2 ^ 5; //设置LED点阵屏连接的I/O口
sbit led_L7 =P2 ^ 6; //设置LED点阵屏连接的I/O口
sbit led_L8 =P2 ^ 7; //设置LED点阵屏连接的I/O口

#define P0M1SET 0x00 //设置I/O口工作方式//00000000
#define P0M0SET 0xff //设置I/O口工作方式//11010011（PxM0为1时设置为强推）（左到右，高到低位）

#define P2M1SET 0x00 //设置I/O口工作方式//00000000

今天测试LCM12864液晶，调试挺长时间的程序液晶始终都没有显示，正在一筹莫展的时候，发现液晶的背光突然变暗，赶紧检查开发板，发现板子上的MAX232发烫，立即关掉开发板上的电源开关，推断是USB转串口线或者是MAX232坏了，现在只能先换一条备用的USB转串口线试试，换完之后MAX232不烫了，唉！好几十块的劣质USB转串口坑爹呐！不过还好，换完USB转串口线就找出液晶不显示的原因了，原来是延时函数的事，有点粗心了。。。

测试程序：
#include <STC12C5A60S2.H> //STC头文件
