I'm working on a home project that centers around a non-Arduino Ubuntu IoT board but I'd like to add an ATmega32U4 chip for USB HID.

I'm thinking about using an Arduino Micro.

The signals to the Micro would have to come from my other board (maybe a Python script), but I haven't found instructions on how to send instructions in real-time from Other Board to Arduino Micro so they go straight through the Micro to the computer it's attached to.

How can one do this?

  • Am I right that your structure is Ubuntuboard --> Micro --> PC? Why do you need the Micro to communicate with the PC? What do you try to achieve? – chrisl Jun 5 at 22:26
  • @chrisl The Ubuntu board doesn't have a microcontroller and it doesn't work as a HID (mouse). That's what I need the Micro for. – sscirrus Jun 6 at 16:34
  • @Juraj I don't understand what you mean by that comment. – sscirrus Jun 6 at 16:34
  • can you just use a usb2serial adapter and the micros tx/rx? – dandavis Jun 6 at 20:01
