I am currently working on a universal remote with some slow success.  Have
got it to record and successfully retransmit a code.

To see the patterns I wrote a simple VBasic app that continually polled a
input on the printer port which was connected to the IR sensor.  Basically
if the pin (Pin 10 I think) was high I draw a dot high, if low draw a dot
low, then increment the x position by one.

Bit like a digital storage cro for digital signals.

I have an example bit map trace file where I recorded several remotes using
this prog (and a 1khz square wave for comparison) and is at
http://www.users.bigpond.com/jkrichards/Pic/trace.bmp

My code is quite ugly and programmed specifically for recording these
patterns.  If you would like a copy or some more info let me know and I will
see if I can find it when I get home.

Subject: [EE]: DVD remote control codes


Does anyone know where I might be able to find the remote control codes for
a Toshiba DVD player?  I'm aware of the recent Nuts & Volts article
detailing the construction of an infrared decoder, but it looks as though
the software for that project might be specific to a protocol that Toshiba
may not use.  I'm hoping to send some commands to the player via a single
PIC pin.  I have tried to use my old analog scope to observe the incoming
data on the player's sensor, but the patterns are difficult to
determine...especially the button release codes.  Has anyone done this
successfully?  What's the best way to go about it?  Any and all tips would
be greatly appreciated.
