This project provides toolchains and other support modules to enable using CMake with the Microchip compilers, although presently only XC16 and XC32 is supported.
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
This project is provided under the same BSD 3-Clause license as
CMake itself. See COPYING.txt
for details.
