PIC单片机利用串口做的红外通信程序 接收.docVIP

注意：波特率不可设的过高 一般设置要低于2400 #include pic.h #include math.h #include stdio.h #define uchar unsigned char #define uint unsigned int __CONFIG(WDTDIS HS PWRTDIS BORDIS);//设置配置位 // WDTDIS : disable watchdog timer // LVPDIS : low voltage programming disabled // HS : high speed crystal/resonator // PWRTDIS : disable power up timer // BORDIS : disable brown out reset #define PORTAIT(adr,bit) ((unsigned)(adr)*8+(bit)) //绝对位操作指令； static bit DI @(PORTAIT(PORTB,0); static bit CK @(PORTAIT(PORTB,1); static bit LA @(PORTAIT(PORTB,2); static bit OE @(PORTAIT(PORTB,3); uchar redata; //--------------------------------------------------- void USART_Init(void); void SEND_Byte(uchar dat); void SEND_DM114_DA(uchar DAT); void delay50us(uchar z); //------------------------------------------------- void delay50us(uchar z) { uchar i,j; for(j=0;jz;j++) for(i=0;i6;i++) ; } //-------------------------------- void SEND_Byte(uchar dat) { if(dat ==0) // DI = 0; RB0 = 0; else DI = 1; // RB0 = 1; } void SEND_DM114_DA(uchar DAT) { uchar i; OE = 1; // RB3 = 1; LA = 0; // RB2 = 0; for(i=0;i8;i++) { SEND_Byte(DAT0x80); DAT = 1; CK = 0; CK = 1; // RB1 = 0; // RB1 = 1; } LA = 1; OE = 0; // RB2 = 1; // RB3 = 0; } //--------------------------------------------------------- //---------------------------------------------------------- void USART_Init(void) { SPBRG = 77; //高速 波特率9600 12MHz SPBRG = 0x4D // SPBRG = 129; //高速 波特率9600 20MHz TXSTA = 0x00; // TXSTA : CSRC TX9 TXEN SYNC -- BRGH TRMT TX9D // 0 0 0 0 1 0 0 RCSTA = 0x80; // RCSTA: SPEN RX9 SREN CREN ADDEN FERR OERR RX9D // 1 0 0 0 0 0 0 0 RCIE = 1; //开接收中断 TXEN = 1; CREN = 1; //接收使能 TRISC6 = 1; //设置为输入状态 TRISC7 = 1; // TXIE = 1; //开发送中断 PEIE = 1; //开外设中断 GIE = 1; //开总中断 TRISB = 0x00; //B口为输出 TRISD = 0x00; PORTD = 0xff; } //-----
