2 Debug Express
4.1 INTRODUCTION
The PICkit™ 2 Microcontroller Programmer allows in-circuit debugging on selected
PICmicro
®
Microcontroller Units (MCUs). In-circuit debugging allows the designer to
run, examine and modify the program while the PICmicro MCU is embedded in the
hardware. This greatly assists the designer in debugging the firmware and hardware
together.
The Debug Express software interacts with the MPLAB
®
IDE software to run, stop and
single-step through programs. One breakpoint can be set and the processor can be
reset. Once the processor is stopped, the register’s contents can be examined and
modified.
4.2 PICkit™ 2 DEBUG EXPRESS
This section explains how to debug programs using the PICkit 2 Debug Express. It is
intended for those new to debugging programs, but familiar with the MPLAB IDE
software.
