'''PIC''' microcontrollers are a [[w:Reduced_instruction_set_computing|RISC]] line from Microchip. They are used in [[ECE 2504 Introduction to Computer Engineering]] and [[ECE 4534 Embedded System Design]]].
==Compiling Code==
MPLAB is IDE recommended by the ECE department. It can be run inside a Virtual Machine, programming using USB passthrough. It can also be installed under wine and the compiler used from the commandline. sdcc is reported to work, and pikdev has a C compiler for the PIC as well.
===Using Wine to Run the Toolchain===The MCC18 toolchain can be run using wine. This page should be updated to give more detailed instructions. ===Makefile Using Wine===The file below is a work in progress.
