用单片机显示数字,要怎么写?答:define uchar unsigned char uchar code table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,//0~9段码 0x77,0x7c,0x39,0x5e,0x79,0x71,};//共阴数码管A~F段码表 uchar buf[]={0x0a,0x0b,0x0c,0x0d,0x0e,0x0f};//显示字母 void delay()//延时子程序 { u...
单片机数字9到0显示程序代码?答:这里给出一种基于Arduino平台的单片机数字0到9显示的程序代码,可供参考:c++ Copy code int ledPins[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11}; //定义LED引脚 int numPins[][7] = { //定义数字0~9的LED点阵图形 {1, 1, 1, 1, 1, 1, 0}, //0 {0, 1, 1, 0,...
写了个单片机矩阵按键控制数码管显示数字的程序,只需要显示0到9就好...答:{ 0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e } ;//共阳极数码管0 为亮 sbit wei=P1^0;void delay(uchar t)//毫秒延 { uint i,j;for(i=0; i<t; i++)for(j=0; j<110; j++);} void display(uchar d){ P1=0x00;wei=1...
