Philippe has been documenting his Linux Bus Pirate adventures, including a tutorial on sniffing different smartcard protocols:
I just tried out my brand new bus pirate on a little project to sniff smartcard transactions (ISO7816). I could happily use the recent raw BRG handling in UART mode and I’m providing on my wiki some tips on how to calculate which baudrate/BRG are needed in order to sniff things properly.
Final word: bus pirate rocks! So great device for a ridiculous price. Thanks folks!!
