16x16點陣使用兩個74HC595顯示圖片源程序

ID:198096 · 發表于 2017-5-8 12:38

最近在研究單片機驅動16x16點陣，分享一個程序~
關于大家想要顯示的圖形，可以自行更改uchar code tab1[] ={..}的內容

單片機源程序：

#include <REG51.H>
//--重定義函數變量--//
#define uchar unsigned char
#define uint unsigned int
#define ulong unsigned long
#define GPIO_KEY P1
//--定義SPI要使用的 IO--//
sbit MOSIO = P3^4;
sbit R_CLK = P3^5;
sbit S_CLK = P3^6;
//---全局變量聲明--//
ulong column; //點陣列
ulong row; //點陣行
ulong dt;
void Delay10ms(unsigned int c);
unsigned char Key_Scan();
//--點陣顯示數組--//
