SPI sniffing with the Bus Pirate just got easier. SPIsniffer is a helper application (power tool?) that accesses the SPI sniffer using the fast binary mode. This is 3 to 4 times faster than displaying snooped output in the terminal mode.
In terminal mode the Bus Pirate decodes raw data to user-friendly HEX formatted numbers, then moves 5 bytes to the serial port for every byte sniffed. Raw values are sent directly to the serial port in binary mode, saving bandwidth and processing time. Sniffing from binary mode is the best tested sniffer mode, and by far the fastest way to sniff the SPI bus with the Bus Pirate. If you need to go faster, consider a logic analyzer like the Logic Sniffer.
