3232LED点阵屏的KeilC51程序基于STC12C5A60S28个大字
32*32LED点阵屏的KeilC51程序（基于STC12C5A60S2，8个大字）
很早之前写的一个8字单红色LED屏显示程序，程序环境为KeilCV3，用的单片机为STC的12C5A60S2，
图的是速度比一般51快，外接11.0592的晶振，完全不延时时可以带4块8字（32*32字）不闪烁。
这个是一个朋友要我给邮局做的显示屏控制程序，顺便发上来给大家做参考。
图片效果：
P0口外接拨码开关，控制显示地址，地址不同，显示内容不同。
//对应硬件接口
//74hc138的ABCD接P2口的0123
#defineLS138_PORTP2
//关键参数声明,4为LED最多能显示的32*32的汉字个数
#defineLED_SIZE4
sbitLS138_OE=P2^4;
sbitHC595_D0=P1^0;//上半部分串行数据输入,对应595的14脚SER
sbitHC595_D1=P1^1;//下半部分串行数据输入,对应595的14脚SER
sbitHC595_CLK=P2^6;//移位寄存器时钟输入,对应595的11脚SCK
sbitHC595_STCLK=P2^7;//存储寄存器时钟输入,对应595的12脚RCK
发送数据为2行数据同时发送，所以需要将2跟线接到上下2行的数据输入端口
接口图示：
KeilC的程序如下所示：
