Hi guys,

For my second PIC project, I'm going to need to detect a button
being pressed on an IR remote control. I've done a small amount of
research on this and from what I've read I'm going to need to hook
up an IR receiver to one of the pins and then time how long pulses
last (and/or the gaps between them depending on the remote).

So, in order to determine how long a pulse lasts I'm thinking that
I'm going to need to do something like:

  - loop waiting for pin to go high
  - reset TMR0
  - loop waiting for pin to go low
  - value in TMR0 now contains length of time of pulse

I just wanted to get some feedback whether I'm thinking of this in
the right way, or whether there is some other technique that is
generally used for timing pulses etc.

Thanks,
Matt
