    'TRANSMIT PIC = one pic

    dont worry, only the part that belongs there
    Ok, just checking because in that one picture it looked like both PICs had the same writing on them.

    Now try this code:


    'RECEIVE PIC

    INCLUDE "modedefs.bas"
    DEFINE OSC 20 'use external 20mhz crystal
    CMCON = 7 : ANSEL = 0 : ADCON1 = 7
    DEFINE LCD_DREG PORTA ' Set LCD Data port
    DEFINE LCD_DBIT 0 ' Set starting Data bit (0 or 4) if 4-bit bus
    DEFINE LCD_RSREG PORTB ' Set LCD Register Select port
    DEFINE LCD_RSBIT 1 ' Set LCD Register Select bit
    DEFINE LCD_EREG PORTB ' Set LCD Enable port
    DEFINE LCD_EBIT 0 ' Set LCD Enable bit
    DEFINE LCD_BITS 4 ' Set LCD bus size (4 or 8 bits)
    DEFINE LCD_LINES 2 ' Set number of lines on LCD
    DEFINE LCD_COMMANDUS 2500
    DEFINE LCD_DATAUS 250

    'try1 = count of times waiting for data, try2 = count of bytes received
    try1 var byte : try2 var byte : temp var word : tempf var word
    temp1 var byte : temp2 var byte : temp3 var byte : temp4 var byte
    input portb.2 : pause 2500
    try1 = 0 : try2 = 0

    loop:
    lcdout $fe , $c0 , "Waiting.." , DEC3 try1 , "," , DEC3 try2
    try1 = try1 + 1 : temp = 0 : tempf = 0
    serin portB.2 , t2400 , [ temp1 , temp2 , temp3 , temp4 ]
    temp.highbyte = temp1 : temp.lowbyte = temp2 : tempf.highbyte = temp3 : tempf.lowbyte = temp4
    if temp + tempf > 0 then try2 = try2 + 1 'if temp+tempf are not 0 then data received
    lcdout $fe , $c0 , "Received." , DEC3 try1 , "," , DEC3 try2 : pause 100
    lcdout $fe , $c0 , "Display.." , DEC3 try1 , "," , DEC3 try2 : pause 100
    lcdout $fe , $80 , "Tc=" , DEC3 temp , "C,Tf=" , DEC3 tempf , "FR" : pause 100
    lcdout $fe , $c0 , "Shown...." , DEC3 try1 , "," , DEC3 try2 : pause 100
    goto loop
    End

    And post a fresh picture if you can
