This fork makes a few changes to src/platform/windows.c to fix detection of the neotrellis monome using an RP2040 on Windows.

Serialosc build instructions using this fork

Requirements:

• MSYS2

Install required packages in msys2 MinGW 64-bit terminal:

pacman -S mingw-w64-x86_64-cmake mingw-w64-x86_64-gcc mingw-w64-x86_64-ninja git

Clone serialosc:

git clone https://github.com/monome/serialosc
cd serialosc

Initialize submodules:

git submodule update --init --recursive

Replace libmonome with this fork:

cd third-party/libmonome
git remote add pico https://github.com/IntaUnta/libmonomeWindowsPico
git fetch pico
git checkout pico/main
cd ../..

Build:

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -G Ninja
ninja

Test:

./bin/serialoscd.exe

You should see:

serialosc [mXXXXXXX]: connected, server running on port XXXXX

libmonome:

libmonome is a library for easy interaction with monome devices. It
currently runs on Linux (on which it is primarily developed), OpenBSD, and
Darwin/OS X.

It was developed to make monome devices easy to use with programming
languages like C and Python, and adding wrappers for use in your favorite
language with a suitable FFI is straightforward.

libmonome has support for 40h and series devices through a unified API,
and by default includes a third backend which wraps around the OSC
protocol and presents the same API as a physical device. This means that a
program written using libmonome can, at runtime, decide whether to
communicate with a running monomeserial instance over OSC or whether to
access the physical device directly.

build like:

    $ mkdir build; cd build
    $ cmake ..
    $ make; sudo make install

libmonome was written by william light (visinin on the monome forums).
