JTAG pinout detector

JTAG is a standard for device testing ports found on the PCBs of many devices. Finding the pads and pinouts for these ports allows hackers to gain access to the embedded systems, their on-board debugging tools, etc., effectively providing a back door. But determining the JTAG pinouts can be a time-consuming and frustrating process. To help in this, a German hardware hacker named Hunz has created the JTAG Finder, an automatic JTAG pin-out detector, using an 8bit AVR ATmega16/32L microcontroller. Details of the project, and a call for others to get involved, can be found on the JTAG Finder wiki. He also wants to build a JTAG Found database of known device pinouts.
