付源码，我拿出74HC595阁下如何应对，串行通信74HC595电路运用

#include #include #define uint unsigned int #define uchar unsigned char sbit SH_CP = P2^0; sbit DS = P2^1; sbit ST_CP = P2^2; uchar temp; uchar code DSY_CODE[]= { 0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90 }; void Delay(uint x) { uchar i; while(x--) { for(i=0;i<120;i++); } } void In_595() { uchar i; for(i=0;i<8;i++) { temp <<= 1; DS = CY; SH_CP = 1; _nop_(); _nop_(); SH_CP = 0; } } void Out_595() { ST_CP = 0; _nop_(); ST_CP = 1; _nop_(); ST_CP = 0; } void main() { uchar i; while(1) { for(i=0;i<10;i++) { temp = DSY_CODE[i]; In_595(); Out_595(); Delay(200); } } }
