EX_X10.C   X10 TO RS232 INTERFACE EXAMPLE ///////////////////////////////////////////////////////////////////////// //// EX_X10.C //// //// //// //// This program interfaces a X10 TW523 unit to RS-232. This //// //// program will accept and send three character codes of the //// //// form xyy where x is A-P and yy is 00-1F. //// //// Key codes 00-0F are translated to the key number. //// //// //// //// A * is sent to indicate transmition was aborted due to //// //// a collision. A > is sent when reception begins to reduce //// //// the chance of attempting to transmit during reception. //// //// //// //// Connect B0 to TW523 pin 1 //// //// B1 3 //// //// B2 4 //// //// GND 2 //// //// //// //// For a 40 pin part such as the 16C74 add jumpers from //// //// 8 to 11, 7 to 12, and change the #USE RS232 to: //// //// #use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) //// //// //// //// (C) Copyright 1996,1997 Custom Computer Services //// //// //// ///////////////////////////////////////////////////////////////////////// #include <16F84.H> #use delay(clock=4000000) #use rs232(baud=9600, xmit=PIN_A3, rcv=PIN_A2) #fuses XT,NOPROTECT,NOWDT #include < x10.c > #include < input.c > main() { char house_code; byte key_code; printf("Online\n\r"); while (TRUE) { if(kbhit()) { house_code = getc(); if((house_code>='A') && (house_code<='P')) { putc(house_code); key_code=gethex(); x10_write(house_code,key_code); x10_write(house_code,key_code); } } if(x10_data_ready()) { putc('>'); x10_read(&house_code,&key_code); printf("%c%2X",house_code,key_code); } } }
