An integrated circuit for learning any IR code ?

Wireless & IoT

Hello

Can someone tell me if it exists some integrated circuits able to learn, capture IR Codes ?

I would like to store IR codes from home remotes ( should be RC5 protocol ), i know that most of universal remotes in the market are able to do that, i’m looking for the chip only

I would like to connect it to a PIC in order to integrate it into a global project.

Many thanks for your help,

Use an MCU, such as your PIC.

Yes, Leon you are right but i do not know how to proceed.

The thing is to copy all edges and durations of each, this is difficult to do that for me.

Can someone put me on the way to start up ?

First you need a “front end”, an IR receiver IC to receive and decode the modulated IR light. SF sells one such device …

Then you need a PIC and some coding. Google is your friend and here’s the first of many such DIY IR projects.

I believe you can buy kits to do the above for cheap $$s as well.
