/-王竹君-/-叔叔谢谢你-/-12M晶振-/-此程序是进行红外线解码，将遥控器发过来的代码解释后用lcd1602显示#include#include#define uchar unsigned char #define uint unsigned int sbit rs=P24;sbit rw=P25;sbit e=P26;sbit ir=P32;Init_t0();Init_ex0();Init_lcd();Wr_lcd_cmd(uchar cmd);Wr_lcd_dat(uchar dat);Delay(uint time);Ircode();Ir_work();code uchar Display=xiewanchen kaifa;code uchar hex=0123456789ABCDEF;uchar table1=Code ;uchar irdata33;uchar rdata4;uchar irtime,irok,irdisp_ok;main() uchar i; Init_t0(); Init_ex0(); Init_lcd(); Wr_lcd_cmd(0x80); for(i=0;i16;i+) Wr_lcd_dat(Displayi); Wr_lcd_cmd(0xc0); for(i=0;i16;i+) Wr_lcd_dat(table1i); while(1) if(irok) irok=0; Ircode(); if(irdisp_ok) irdisp_ok=0; Ir_work(); P1=rdata3; Init_t0() TMOD|=0X02; TMOD&=0XFe; TL0=0X00; TH0=0X00; EA=1; ET0=1; TR0=1;Init_ex0() IT0=1; EA=1; EX0=1;Wr_lcd_cmd(uchar cmd) Delay(400); rs=0; rw=0; e=1; P0=cmd; _nop_(); _nop_(); e=0; Wr_lcd_dat(uchar dat) Delay(400); rs=1; rw=0; e=1; P0=dat; _nop_(); _nop_(); e=0;Delay(uint time) uint t; t=time/2; while(t-);Init_lcd() Wr_lcd_cmd(0x38); Delay(200); Wr_lcd_cmd(0x38); Delay(200); Wr_lcd_cmd(0x38); Delay(200); Wr_lcd_cmd(0x0c); Wr_lcd_cmd(0x06); Wr_lcd_cmd(0x02); Wr_lcd_cmd(0x01);Inter_t0() interrupt 2 irtime+;Inter_ex0() interrupt 0 static uchar i; static uchar irflag=0; if(irflag) if(irtime33) i=0; irdatai=irtime; irtime=0; i+; if(i=33) i=0; irflag=0; irok=1; else irflag=1; irtime=0; Ircode() uchar i,j,k=1,dat=0; for(i=0;i4;i+) for(j=0;j7) dat=dat|0x80; if(j1; k+; rdatai=dat; irdisp_ok=1; Ir_work() uchar i; table15=hexrdata0/16; table16=hexrdata0%16; table18=hexrdata1/16; table19=hexrdata1%16; table111=hexrdata2/16; table112=hexrdata2%16; table114=hexrda
