Dear friend,
I found this circuit in net, rx.GIFtx.GIF
So i want to replace that IR and I want to connect direct from wire like this.test.JPG, please check attached file also here I upload code also,
I tried to check from Proteus its not working so please help me....
thanks in advance

hello

on transmitter
when you applya 1 logic level on RC4 to active the IR led1 trough the transistor,
T1 is ON, so level across collector is 0V so => 0 logic level

you connect it direct to RA3 input on Receiver
so you have maybe to reverse the logic level !
or try a direct link RC4 transmitter to RA3 Receiver .. with a pull up resistor on RC4
 

I already tried to connect direct also, but same thing happened..

- - - Updated - - -

I didn't use this section I used direct transistor for this section.. I need to transfer data from Tx to Rx which is not transferring... :sad:
 

hello,

if IR link with a TSOP1738 as receiver ,you have a "porteuse" carrier frequency of 38 khz
emitted by the transmiter,,
wich is eliminated by the IR receiver !
you can't use direct link without modify the software on each side.!
Another way could be to use soft Uart link.
