作者：時(shí)間：2016-12-02 來源：網(wǎng)絡(luò)

試驗(yàn)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(shí)函數(shù)

void DigDisplay(); //動(dòng)態(tài)顯示函數(shù)

void main(void)

{

while(1)

{

DigDisplay();

keys();

}
