Debugging the debugger

During the development of the USB-stick logger published in the September 2011 edition of Elektor we couldn’t manage to get the communications going to the microcontroller via Microchip’s In Circuit Debugger 3 (ICD 3). We did manage to program the flash memory of the chip in the circuit, a PIC24FJ64, using the predecessor of the debugger, the ICD 2.
