矩陣鍵盤實驗程序

試驗效果如下：#include#define duan P0//段選#define wei P2//位選unsigned char code wei1[8] = {0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};//位選控制 查表的方法控制unsigned char code duan1[17] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};//0、1、2、3、4、5、6、7、8、9、A、b、C、d、E、F的顯示碼unsigned char ge;unsigned int temp;void keys(); //鍵盤掃描函數(shù)void s(unsigned char xms); //延時函數(shù)void DigDisplay(); //動態(tài)顯示函數(shù)void main(void){while(1){DigDisplay();keys();}}
