Universal infrared remote control receiver with 89c2051

transceiver ir code for 2051

Hi @ll,

I would like to build a universal infrared remote control receiver into a hobby grade project based on Atmel 89c2051.

There are many projects based on PIC controllers as UIR (12c509 and 16f84), UIRt, IRMan and others.
These devices receive IR and calculate a 6byte value which is unique to every key beeing sent.

There are no sources available for these projects , but as there's also a project based on PIC12c509, it can't be too hard.

I tried metering the time between pulses, identifying them as hi/lo, but I don't know how to limit received values with different lengths to a fixed unique value (kind of checksumming or simply shift bits into a circular buffer?). Additionally, some remotes have a bit that gets toggled on every send.

I don't want to decode (which would be limited to a few remotes talking know protocols like RC5, RECS80, Sony), I want to keep it as universal as possible.

Can somebody please tell me a good algorithm or show me sources?

At least for RC5 there is a c source at www.8052.com.

Check the codelib there.

thx, but I'm currently doing RC5 which limits my application to just a few remotes.
As I said above, I would like to do it in a universal way.

hello there..

i need a program code to decode rc5 sony remote control . i want to use 8051 uc but i found decoder code for 2051 uc for easytip1 code 718 from this site **broken link removed**

i can't find the technical detail of easytip remote control or find code for 8051 deocder sony rc5 code

plz help me to sort out the problem

thank you

universal ir remote receiver

Hi

RC5 is standard

Its same for Sony RC5 ,Philips RC5 or XX RC5.

Easy way to use RC5 and 8051 is to use Bascom 8051 compiler.
Just a few lines and it works

can u elaborate more...about "adding few lines"

Can you please reupload the file ?

I did project like that last year using ATTINY2313. It was a Universal Remote Control Transceiver. Have been tested at SONY TV, K-world TV-tunner, and a dvd player. Here's my project

thanx JaMe.....great work
