Arduino Core for mbed enabled devices

The repository contains the Arduino APIs and IDE integration files targeting a generic mbed-enabled board

Installation

Clone the repository in $sketchbook/hardware/arduino-git

mkdir -p $sketchbook/hardware/arduino-git
cd $sketchbook/hardware/arduino-git
git clone [email protected]:arduino/ArduinoCore-mbed mbed

Then clone https://github.com/arduino/ArduinoCore-API in a directory at your choice.

git clone [email protected]:arduino/ArduinoCore-API

Remove the symlink to api you can find in $sketchbook/hardware/arduino/mbed/cores/arduino and replace it with a symlink to ArduinoCore-API/api

Open Arduino IDE; you should now see three new targets under MBED boards label

You may also need to install ARM build tools if you see an error like the following when you attempt to build for one of the mbed-os enabled boards.

fork/exec /bin/arm-none-eabi-g++: no such file or directory

The missing ARM build tools can be installed by using the Boards Manager option in the Arduino IDE to add the Arduino mbed-enabled Boards board package.

Adding an mbed target

Adding a target is a mostly automatic procedure that involves running https://github.com/arduino/ArduinoCore-mbed/blob/master/mbed-os-to-arduino after setting BOARDNAME and ARDUINOCORE env variables. Actions marked as TODO must be executed manually.

Minimum Example: ./mbed-os-to-arduino -r /home/alex/projects/arduino/cores/mbed-os-h747 PORTENTA_H7_M7:PORTENTA_H7_M7

How to build a debug version of the Arduino mbed libraries

• Modify mbed-os-to-arduino

mbed_compile () {
-       PROFILE_FLAG=""
        if [ x"$PROFILE" != x ]; then
                PROFILE_FLAG=--profile="$ARDUINOVARIANT"/conf/profile/$PROFILE.json
                export PROFILE=-${PROFILE^^}
+       else
+               export PROFILE="-DEBUG"
+               PROFILE_FLAG="--profile=debug"
        fi

Using this core as an mbed library

You can use this core as a standard mbed library; all APIs are under arduino namespace (so they must be called like arduino::digitalWrite() )

The opposite is working as well; from any sketch you can call mbed APIs by prepending mbed:: namespace.
