16x32 P10广告屏点阵任意位置画点画线单片机程序

ID:168911 · 发表于 2021-6-5 20:45

16x32 P10广告屏点阵任意位置画点画线，点阵直接用P10单红门头广告屏，省去了自己焊接，刷了一个时钟走时程序，图片中间点是秒闪,
用的是12c5a60s2。

单片机源程序如下:
#include <REG52.h>
#include<intrins.h>
#include<math.h>
#define uchar unsigned char
#define uint unsigned int

#define BB P3
sbit SHCP=P2^3;       // 移位时钟
sbit STCP=P2^4;       // 锁存时钟
sbit DATA=P2^5;    // 数据输出
sbit OE = P2^0;          // 使能输出

uchar PLAYBUF[64];
uchar a,b;

uchar sec=0,min=0,timecount=0;
bit point;

void serial_input(uchar dat);
void LED_dot_write(uchar x,uchar y,uchar c);
void line(uchar  x1, uchar  y1, uchar  x2, uchar  y2, uchar c);
void number(uchar su,uchar x,uchar y,uchar c);

void display();
