Pulse Decoding

[Freman]

G'day there.

I've still trying to replace a pic on a board. I've got a whole new approach that I'm working on.

I want to decode the pulses received from the RF receiver.

I don't have a CRO or anything useful like that, but can anyone give me any idea how I might have the pic read these pulses and store details about them in eeprom?

Or perhaps how I can read and compare these pulses to a list of knowns? (I have the specs on the transmitter, but not the receiver)

EDIT -

Ok, I've hacked myself up a cheap scope (sound card + voltage divider )

So um... anyone know how I might go about reading these signals with a PIC/picbasic?
