IR Remote Control with 8051

8051 remote control

Hi all,
I need to interface my '8051 with an IR remote control, exaclty with a TV remote control!
I explain better: I have a TV remote control (I suppose RC5-protocol compatible) and I want to control my 8051 : when I press "1" on the remote control , I need to close a rele', pressing "2" I need to turn off it, and so on...

Somebody knows if is there a simple way to interface such microprocessor with a remote control? via a dedicated chip? via a software routine? or...?

Any ideas is welcome!

Many thanks to all in advance!

Sirio.

RC5 is pretty simple to decode, there are many samples on the net.

For the hardware part the easiest thing to use an integrated IR demodulator (for example the Vishay TSOP or SFH series), from there on it's basically a serial protocol you can handle in the microcontroller.

Perhaps this will get you started:

Very nice page, but...

I am not too friendly with ASM...

I was searching for someting in "C", a language that I know, but asm is for me hard to integrate in a C program...

Also, all this people (in the link) write in asm... I think because it is faster: The question is if I would be able to write a RC5 decoder in C fast enought......... :wink:

I think that, to begin working with, I need an example, also academic, but in this language.

I tried with Google, but with no appreciable results...

Thank you very much for this, but have you (or something else), something more?

Ciao, Sirio.

Perhaps learn to use Google a bit better?

It's 'C', but it still depends on your specific compiler and setup whether or not the code can be used without modifications (most likely not...)

Again good luck and have fun.
