I'm working on an emoji keyboard and it requires different input depending on the OS it's connected to. I've written the relevant methods using Arudion's default Keyboard library and can manually set which one is used. I'm wondering if there is a method or library for Arduino (currently using a Adafruit Feather 32u4 Bluefruit LE) that allows me to detect the OS.

If not, I'll set up a switch, but that'll cost me pins.

    This information is not formally available to a USB peripheral like an Arduino; there might be ways you could "fingerprint" OS behavior from deep in the library code of a Leonardo-type board, but that could trivially change. Commented Apr 17, 2018 at 22:27
  • @ChrisStratton Thanks. That answer the question. I'm going to have to find a work around. Commented Apr 18, 2018 at 20:04

If you can't get the OS from the USB port, why not use the existing keys/inputs to set the mode on startup? That is, if you tell the user to press different combinations of 2 buttons on startup, you have 4 (2 bits => 4 values) different paths on startup:

00 => Normal startup, don't change mode
01 => OS 1
10 => OS 2
11 => OS 3

  • Might do that, but I like the idea of a clear multi option switch for the user to be understand/set at any point. Commented Apr 18, 2018 at 20:06
