In the previous chapter, we used static display 1234.5, which was simpler without loop statements. This time, we use dynamic display 01234567
Directly give the reference program: use Keil uVision5 for programming and Proteus 8 Professional for simulation.
#include #include #define uchar unsigned char #define uint unsigned int uchar code DSY_CODE[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90}; void delay(fly x) { flying i; while(x--) { for(i=0;i<120;i++); } } void main() { fly i,j,w=0x80; while(1) { for(i=0;i<8;i++) { for(j=0;j<7;j++) { P2=0x00; w=_cror_(w,1) ; } P0=DSY_CODE[i]; //Send segment code P2=w ; //Send bit code delay(1); } } }
