This is experimental, community-supported Windows port of MicroPython.
It is based on Unix port, and expected to remain so.
The port requires additional testing, debugging, and patches. Please
consider to contribute.
To cross-compile under Debian/Ubuntu Linux system:
sudo apt-get install mingw32 mingw32-binutils mingw32-runtime
make CROSS_COMPILE=i586-mingw32msvc-
The port requires additional testing, debugging, and patches. Please
consider to contribute.
To compile under Cygwin:
Install following packages using cygwin's setup.exe: mingw-gcc-g++ make
make CROSS_COMPILE=i686-pc-mingw32-
To compile using Visual Studio 2013:
Open micropython.vcxproj and build
To compile using Visual Studio 2013 commandline:
msbuild micropython.vcxproj
