IR remote control receiver with PIC18f452 using ccs compiler

[afzalm]

Hello There!
Im new here,student,have a project to work on IR remote controller receiver using pic,but im very confused how to do it? any one please help me?

Usually the IR remote controller is made using IR led and TSOP1738 sensor together with the use of serial port of any micro-controller to send codes.If you want to use TSOP1738 ,you have to generate 38kHz 50% duty cycle signal to drive IR led.Choose any PIC uC with PWM feature ,then you can use PWM to generate accurate 38kHz signal. IF you are not familiar with PIC ,just google it you will get lot of tutorials and example codes for this project. Don't forget to read the datasheets thoroughly.......

Dear Mukesh Thanks fro you kind replay,i have got TSOP1738,how i decode a standard sony tv remote control codes,i want to do that if i press a button like "1" it energize a relay,and again de-energize it vice versa,hope you will help me in this regard.

Dear mukesh thanks for your kind help and reply.
i have got tsop1738,how i decode the standard sony tv remote control codes and perform any action against the button pressed of remote,like i press 1 button it just actuate a relay,when again press 1 it deactivate the relay and vice versa,please help me how i decode remote pulses and done it?

Sorry I don't have such experience in decoding the codes of remotes .......
If you want to use SONY's remote you must know its baud rate and key codes for each key. I don't know where from we can get it. One method is that, connect your remotes output to a CRO and manually calculate the code and baud rate. Another method is that, use the the automatic baud rate detection feature of PIC18FXX series uP like 18f4550 to detect the code , but that will be complex and difficult, you should be familiar with the PIC18fXX. Try yourself ....
Why you want to use tv remote control ? I suggest you to make you own remote using uC like 16f876.
that will be the best and simple way.
