CMake for the Microchip Toolchain

This project provides toolchains and other support modules to enable using CMake with the Microchip compilers. This fork focuses on supporting CLang compiler frontend for XC8 introduced in version 2.0.

Usage

First, you need to somehow get a copy of this project as a subdirectory of your project named external/cmake-microchip. If you use git, the easiest way is to add a submodule:

git submodule add git://github.com/Elemecca/cmake-microchip.git external/cmake-microchip

Then add this snippet at the very top of your CMakeLists.txt:

# set up the Microchip cross toolchain
set(CMAKE_TOOLCHAIN_FILE external/cmake-microchip/toolchain.cmake)

# set the default MCU model
set(MICROCHIP_MCU PIC24FJ32GB002)

The target MCU is set by the MICROCHIP_MCU variable. It can be set in CMakeLists.txt as above or on the CMake command line like so:

cmake -DMICROCHIP_MCU=PIC24FJ256GB004 .

If you wish to use the 'legacy' xc8 compiler (xc8) over the clang-based version (xc8-cc), this can be achieved by telling CMake to 'force' the use of non-cc version:

cmake -DMICROCHIP_XC8_FORCE_NON_CC:BOOL=ON .
