Hi Everyone,
I am trying to build an IR circuit to TX/RX serial data. I saw the project
at http://www.rentron.com/Infrared_Communication.htm I built the same circuit

as in figure 6/7. Except, I used a 2N3906 instead of the 2N4403 transistor.

I am using a F628 to send a 40khz carrier wave and then am combining it with

the serial data  out of pin B2. I checked the 40khz carrier on a scope it looks

fine. I checked the serial data on hyper term. That looks fine. When the
IR Leds xmit they send to a GP1U26X module. This is connected to a F84, like
in figure 7. ( I know the GP1U26x has a different pin out than fig. 7) Basically

I have the data-out pin going to my rx pin on the pic. and am receiving garbage.

However, if I hook the rx pin to TX from my PC serial port it works fine. I
can echo the characters back to hyper term and display them on an LCD hooked
to the
F84.
I am using CCS C and basically am just waiting for character in a while loop

 while(1) {
 j++;
 if(j>=17) { lcd_putc("\n                 \n");j=0;}
                                //clear bottom line at 17 chars
 c=getc();                     // waits for a char on rx pin
 lcd_putc(c);                 // puts char out to lcd
 putc(c);                    // puts char out to PC serial port
          }

Code works fine when hooked to serial TX pin,  does not work from data-out of

GP1U26x.
I would greatly appreciate any suggestions.
Thanks in advance,
                 Kevin
