求51單片機(jī)共陰極四位數(shù)碼管0000-9999循環(huán)的代碼編寫思路

相信這個(gè)可以幫助到你 #include #define uchar unsigned char void delayms(uchar ms); int main(void) { unsigned char led[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90}; //0-9共陽(yáng)數(shù)碼管段碼 unsigned char i; P2=0x00; //共陽(yáng)數(shù)碼管位選置0 while(1) { for(i=0;i
