Hardware for Programming and Debugging

The dsPICDEM™ MCHV Development System, with its built-in SKDE debugger/pro-

grammer, provides an all-in-one solution for debugging and programming applications

using MPLAB IDE. The Starter Kit’s debugging/programming operations are controlled

by a PIC18F67J50 MCU running at 48 MHz. The PIC18F67J50’s built-in USB engine

provides the communications interface between the Starter Kit and the host PC.

Power to the Starter Kit is provided via the isolated 3.3V rail. Proper Starter Kit main

system power is indicated by the green LED D19. The PIC18F67J50 MCU accom-

plishes debugging or programming of the target dsPIC33F by controlling the target’s

MCLR, PGC1/EMUC1, and PGD1/EMUD1 signals. A Microchip 25LC010A serial

EEPROM is used to store the Starter Kit’s serial number and debug control information.

Isolation for the MCLR, PGC1/EMUC1, and PGD1/EMUD1 signals is provided by the

digital isolators U22, U23, U1 and U3.
