The centerpiece of our tool set is the software MPLAB Integrated Development Environment, or "IDE."

MPLAB IDE has enjoyed many years of use and evolution, tracking Microchip's expanding catalog of microcontrollers and digital signal controllers.

One of the most popular elements of MPLAB is the software simulator, MPLAB SIM.

This component, like the MPLAB IDE is free.

We'll cover the basic elements of the simulator in this web seminar, including:

?How to configure MPLAB IDE to use MPLAB SIM as the current debugger

?How to run your code in MPLAB SIM halting at a breakpoint

?How to single step through your code

?How to set watchpoints on data variables in your code

?How to run and halt your code

?How to use a stimulus to simulate external inputs to your hardware

?How to use the __DEBUG variable to make conditional code execution while debugging

?How to insert fprintf statements in your code to monitor the executing routines

?How to measure the execution time of your code, and

?How to record code as it executes, capturing its history in a buffer to be reviewed.
