3.2.10 Hardware for Programming and Debugging
The dsPICDEM™ MCHV-3 Development Board, with its built-in Starter Kit on-board
debugger/programmer, provides an all-in-one solution for debugging and programming
applications using MPLAB IDE. The debugging/programming operations are controlled
by a PIC24FJ256GB106 MCU. The PIC24FJ256GB106 device’s built-in USB engine
provides the communication interface between the Starter Kit on the board and the
host PC.
Power to the Starter Kit on the board is provided via the isolated 3.3V rail. The
PIC24FJ256GB106 MCU accomplishes debugging or programming of the target PIC
MCU or dsPIC DSC by controlling the target’s MCLR, PGC1/EMUC1 and
PGD1/EMUD1 signals. A Microchip 25LC256 serial EEPROM is used to store the
serial number and debug control information. Isolation for the MCLR, PGC1/EMUC1
and PGD1/EMUD1 signals is provided by the digital isolators, U3, U6, U22 and U7.
