用转接线是非常方便的。。

谢老大建议,会做的哈。。

木事,反正配转接线。。
先上几个测试程序:
LED+SMG+LCD12232F(在板板上全部验证通过):
//LED测试程序:

{

while(1)
{

delay(60000);
}
}
//SMG测试
#include "reg52.h"
#include "absacc.h"
#define uchar unsigned char
#define uint unsigned int

uchar SMG_DM[]={0xC0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90};
uchar SMG_WM[]={0x00,0x20,0x40,0x60,0x80,0xA0};
void delay(uint t)
{
while(t--);
}
void main()
{
RD=0;
while(1)
{
WM=(WM&0x1F)|SMG_WM[0]; DM=SMG_DM[6]; delay(100);
WM=(WM&0x1F)|SMG_WM[1]; DM=SMG_DM[5]; delay(100);
WM=(WM&0x1F)|SMG_WM[2]; DM=SMG_DM[4]; delay(100);
WM=(WM&0x1F)|SMG_WM[3]; DM=SMG_DM[3]; delay(100);

WM=(WM&0x1F)|SMG_WM[5]; DM=SMG_DM[1]; delay(100);
}
}
LCD :
//LCD测试

sbit RS = P2^5;

uchar dis[]="我爱单片机!";
void delay(uint k)
{

}
//--------------------------------------------------------------------------------------

//-------------------------------------------------------------------------------------
void Wr_CHI(uchar str[],uchar num)
{
uchar i;
for(i=0;i
{

delay(100);
}
}
//-------------------------------------------------------------------------------------

矮油,挺好啊。还有控制强电的模块
