logic sniffer

You can use the bus pirate as a logic sniffer. I would recommand using the Open bench logic for this. You can use this tutorial : http://dangerousprototypes.com/2012/02/12/sniffing-spi-data-with-bus-pirate/ Which is designed by the bus pirate constructor to sniff data Note that this can be used only up to 5 input.
