the JTAG (joint test action group) interface is used to debug and load test program's direct into the camera's memory. This provides step-by-step debugging and more usefull stuff..

The hardware

The needed hardware is very minimal and is compatible with Macraiglor WIGGLER cable. The indicated references TP1->TP5 (TP4 is the reset and is optional) are painted on the PCB of the Gsmart350. For other camera's refer to the pin number of the ASIC.

The software

The software can be found at macraigor's site for free. (Can only be run in windows with the wiggler interface :-( ). more information on how to use the software will be given later..
