40KHz? Are you receiving me?

From the figures you have given, it looks like the modulation frequency might be 40 kHz; the actual data is slower. So, as long as your IR receiver module can handle 40 kHz, decoding the data (pulse widths and spaces), which is in milli seconds, should most certainly be within the scope of PBP.

Depending on the range you expect, even a generic 36 - 38 kHz IR module should work fine at 40 kHz.

Hi all,

Thanks for the responses. Sorry it takes me so long to respond. I'm in Australia, so with the time differences all of your responses come in while I'm asleep.

I'm using a 40KHz phototransistor to receive, yes, and interfacing it to a PIC16F628A oscillating at 4MHz.

Thanks for the example code, DaveC3. It's not a remote control that I'm trying to read from, but I imagine it's a similar process across the board. I'll pick that code apart and see what I can come up with.
