CMake modules for the Microchip embedded toolchain

CMake for the Microchip Toolchain

This project provides toolchains and other support modules to enable using CMake with the Microchip compilers, although presently only XC16 and XC32 is supported.

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/juanAngel/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)

This code fragment must be placed before "project" command to have effect

MICROCHIP_MIN_HEAP_SIZE sets the heap size

MICROCHIP_MAP_FILE allows you to generate a map file

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 .

You can set the variable "MICROCHIP_LINK_SCRIPT" to specify a linked script

Copying

This project is provided under the same BSD 3-Clause license as CMake itself. See COPYING.txt for details.
