BEFORE BEGINNING THE LESSONS
The following series of lessons covers the basics of developing applications for the
Microchip PIC18 series of microcontrollers. Working with the MPLAB
C Compiler for the PIC18, and the PICkit™ 3 Development Programmer/Debugger is
introduced in a series of lessons that cover fundamental microcontroller operations,
from simply turning on an LED to creating Interrupt Service Routines.
All lessons can be completed with the freely available MPLAB C18 Student Edition
compiler in the freely available Microchip MPLAB Integrated Development
Environment. The lesson files may be installed from the included CDROM.
Please note that these lessons are not intended to teach the C programming language
itself, and prior familiarity with the C language is a prerequisite for these lessons.
