I expected it would be fast enough as well. It appears to be about 3 ticks
off in the worst case, not much I suppose, except that it adds up to about
180us. I'm using the hardware capture module to grab the times, if anything
I would expect it to be missing some ticks, not getting extras. I'll keep
checking on things. I suppose my oscillator could be running fast. On the
PIC, I'm running a 32.768Khz crystal with caps on the timer 1 oscillator and
using a 1:2 prescale to get the clock ticks for 1/16384 sec. Then I just set
the capture module to capture the number of ticks on the rising or falling
edge. Nothing really complex in the code.

If I could convince the oscillator to keep running when connected to the
logicport, I could actually check for speed error there and compare the # of
pulses to the actual waveform from the IR receiver module.

irrecord does detect the RC-6 protocol after the 2 lines of dots at this
point. It fails to get any buttons to map, but I think that's because of the
readdata() error I'm getting. I haven't had a chance to sit down and debug
that yet. I'm not actually using a config file at this point, I just gave it
a filename that didn't exist and let it try to create a config file. I did
try using remotes/generic/RC-6.conf, and it gives me the same issue there.
If you need any files or capture output, let me know and I'll post it up.
Any help would be great.
