Title: TMK for PS/2 keyboard
Post by: equalunique on Thu, 18 January 2018, 10:18:27

I am wondering what's required to connect a TMK keyboard to a PS/2 port on a computer.

Will stock TMK support this, or is there more coding required? Is it dependent on the TMK keyboard? Has it been done? Is it hard to do?

I'd be interested in doing this with QMK too, but I haven't found anyone messing with PS/2 keyboard input using QMK. For TMK, there are some posts about converting from PS/2 to USB, but that's like the opposite of what I'm looking for.   :))

Probably best to ask the fellow who wrote/writes it by posting here (https://geekhack.org/index.php?topic=41989.0).

Thanks for the tip. I sent the question to one of his threads related to PS/2: https://geekhack.org/index.php?topic=14618.msg2549337#msg2549337

With stock TMK you can make PS/2 keyboard.

While TMK firmware(with PS/2 converter hardware) can act as a PS/2 host,  it can't communicate with computer as a PS/2 keyboard.  You need to write code to implement PS/2 peripheral side protocol if you want to make your own PS/2 keyboard with TMK.
