While I did some searching, I found it difficult to answer my question specifically...so I figure I'd pass it along to someone who's far more familiar with the hardware.
I need a PIC (hopefully Arduino will work!) to take, as inputs, the outputs of 6 separate acoustic transducers. I'm only interested in the IRQ response. The idea is to run a simple algorithm to calculate the time difference between each IRQ ~ this is going to be used in a TDOA calculation that's running on a PC.
Perhaps I can't do it on the IRQ level...that's okay. I just need to be able to compare when the sensor 'got something' to when another sensor 'gets something' and then come up with all my time differences.
This is my first post ever...so please...be gentle!
