Hello! Everyone,
I am attaching the project for decoding Extened-NEC Protocol of my TV Remote Controller using PIC18F4550 and TSOP1738.
Timer-1 is used in this project to call NEC Protocol decoder State Machine, you can use any other timer to call this function, just make sure that timer is configured to interrupt at every 10 micro-second.

Decoded Address and Command are then Displayed on 2x16 LCD.

Schematic Diagram is here:


My Setup (I used my Development Board)


Video of this project is available here:
