+# 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`
+
+```bash
+mkdir -p $sketchbook/hardware/arduino-git
+cd $sketchbook/hardware/arduino-git
+git clone git@github.com:arduino/ArduinoCore-mbed mbed
+```
+
+### Clone https://github.com/arduino/ArduinoCore-API into a directory of your choice.
+
+```bash
+git clone git@github.com:arduino/ArduinoCore-API
+```
+
+### Update the `api` symlink
+
+Create a symlink to `ArduinoCore-API/api` in `$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 $sketchbook/hardware/arduino-git/mbed
+./mbed-os-to-arduino -r /home/alex/projects/arduino/cores/mbed-os-h747 PORTENTA_H7_M7:PORTENTA_H7_M7
+```
+
+### How to build a debug version of the Arduino mbed libraries
+* Modify `mbed-os-to-arduino `
+```diff
+mbed_compile () {
+-       PROFILE_FLAG=""
+        if [ x"$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.
