PIC-ICD2-POCKET is the world's smallest PIC ICD2 debugger and programmer, with only 55 x 55 mm (2.16 x 2.16") dimensions and only 30gr weight (without ICSP cable and packing) this little device fits in your pocket and is very convenient to carry with you when you work in field. PIC-ICD2-POCKET is completely replacement of Microchip's original MPBA-ICD2 and with it you can do everything you can do with the original MPLAB-ICD2, the only difference is that MPLAB-ICD2 have also RS232 while PIC-ICD2-POCKET operates only from USB. PIC-ICD2-POCKET is a low cost, real-time debugger and programmer for selected PIC MCUs and dsPIC DSCs. Programs can be downloaded, executed in real time and examined in detail with the debug functions of MPLAB. Set watch variables and breakpoints from symbolic labels in C or assembly source code, and single step through C source lines or into assembly code. PIC-ICD2-POCKET can also be used as a development programmer for supported MCUs. The secret behind In Circuit Debugging is two dedicated hardware lines (microcontroller pins used only during debugging mode) that control In Circuit Serial Programming (ICSP) of the device and, afterwards, debugging through proprietary, on-chip firmware. The ICD 2 debug features are built into the microcontroller and activated by programming the debug code into the target processor. There is some shared overhead expense that includes one stack level, some general purpose file registers and a small area of program memory.
