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

Clone https://github.com/arduino/ArduinoCore-API into a directory of your choice.

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

Update the api symlink

Create a symlink to ArduinoCore-API/api in $sketchbook/hardware/arduino/mbed/cores/arduino.

Test things out

Open the Arduino IDE.

You should now see three new targets under the MBED boards label.

This procedure does not automatically install the required ARM compiler toolchain.

If the toolchain is missing, you'll see errors like this when you try to build for an mbed-os enabled board.:

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

To install ARM build tools, use the Boards Manager option in the Arduino IDE to add the Arduino mbed-enabled Boards 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 the BOARDNAME and ARDUINOCORE env variables. Actions marked as TODO must be executed manually.

Minimum Example:

cd $sketchbook/hardware/arduino-git/mbed
./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.
