Arduino Core for Mbed CE Arduino devices

This repository is a wrapper which bundles Mbed CE as an Arduino core so that Mbed CE can be used as a platform in the Arduino IDE. It is designed to perform a similar function as the mainline ArduinoCore-mbed repository while being a bit less janky.

The CMake build scripts in this repo perform two distinct functions:

• Create a precompiled build of Mbed OS, and then install it plus the supporting files in the correct directory structure to be an Arduino core
• Compile the Arduino core library and dependency libraries in-place. This is mainly done to check that they compile, and is not intended for actual usage (though you can use this repo to compile and link Mbed CE Arduino applications).

Compiling an Arduino core for Mbed CE

1. Set up the toolchain as described in the Mbed CE wiki.
2. Install Python dependencies. On Ubuntu >=22.04, run xargs apt-get install -y < mbed-os/tools/requirements.apt.txt. On other OSs, run python3 -m pip install -r mbed-os/tools/requirements.txt.
3. Create a build directory and cd into it: mkdir build && cd build
4. Configure CMake: cmake .. -GNinja -DCMAKE_BUILD_TYPE=<Debug|Release> -DMBED_TARGET=<target> -DUPLOAD_METHOD=NONE. The DCMAKE_BUILD_TYPE may be set to Debug or Release to generate a debug or release build of the core. The MBED_TARGET may be set to any supported target for this repo -- check the directory names under variants/ to see each supported target.
5. Build: ninja
6. Generate the package: ninja package. This will generate a zip file containing the core in the build folder -- for example, mine is called ArduinoCore-mbed-ce-RASPBERRY_PI_PICO-Develop-1.0.0.zip.

Installing the Core Locally

The easiest way to install the core locally, per here, is to copy it to your sketchbook directory.
