i implemented an ir receiver in a pic 16f628. i did this according to some
rc5 code information, i found on the web.

now i tried this out with remote controls from pioneer, sony, panasonic,
united, jvc,...but none worked.

checking the signal with an oszilloscope, i found it to be very different
from what i expected.
i thought that everybody uses some bi-phase coded rc5 code with 880us bit
timing, but...
...what i found is some very slow 1-0 sequence, looking like some kind of
synchronization, followed by an 1-0 sequence pattern, where some 1 pulses
miss some times.

does anybody have information on this code, most manufacturers seem to
use?

or does anybody have an idea on a simple way to build an universal
receiver?

thanks for your help!
tino
