The OHMni-Stick firmware utilizes the Arduino framework and is being developed as a PlatformIO project.

Using the familiar and widely accessible Arduino framework and libraries should make it easy to adapt and modify the code to suit new use cases or add new functionality.

The firmware emulates a generic USB HID mouse and has been tested to work with computers, tablets and phones when using a USB OTG adapter.

Like the rest of this project the code is provided freely as open source.
