| infrared RC5 problem |

Hi
Im using an tsop 1736 to recieve rc5 codes. The out is connected to RB0 (int). im using an 18f2550 on an 20mhz xtal (internal freq is 48mhz)
the code I use I found on
http://www.ccsinfo.com/forum/viewtopic.php?t=4215&highlight=rc5+sony
and actualy it is working bit...
the only problem is that I have to push a button a few times (5 times or more) and then my USB is not working any more,
does anyone have working RC5 recieve and decode software wich is fully interupt driver?

Does this code really work? It looks like it is missing something. For example there is a #include with nothing following it, and I don;t see a #use232 type statement anywhere. Does anyone have to full code for this, it looks like fun to play with.

im not verry patient so I wrote some code that does decode rc5 codes
this one workt much better, but only it does not read the adress of the remote, ik shoult but it doesnot work. my code so far.
