Hi everybody
I've just started with a zx1281e from oaks micro and sofar it seems very nice to play with!. I'm trying to get the AN204 - IR application to work.I can see that a signal is receieved when pushing a remote button but don't get any correct commands. I believe this application was written for ZX 24/40. Are there different timing issues with zx1281 compared to zx24/40 ?
Other differences to consider?
Any help would be appreciated
Regards Hucke

The main difference is that there are many different kinds of IR protocols. The application note example code was written for one specific Sony protocol. You should look up your IR remote to find out its protocol.

You may want to start with a simpler program which just calls InputCapture() and displays the pulse widths.

I show a simple way to capture and view IR and RF codes at http://davehouston.org/learn.htm. There's a newer app call SoundCheck which you might consider for the capture.
