Does anyone have detailed electrical specs for the PS/2 interface? Google is not my friend; I'm finding billions of Playstation links, and basic specs for COTS keyboards, but nothing detailed enough.
I want to interface a 3.3V micro (with 5V-tolerant inputs) to a PS/2 keyboard; can I simply operate the clk/data pins in "open collector" mode with a pullup to +5V?
Or is this even necessary - what's Vih for the keyboard; will 3.3V driven from the micro in totem-pole mode be high enough?
Thanks.
They're all over the place.
Then why are you posting from it?
Try googling for "PS/2 keyboard interface spec".
Good Luck! Rich
Don't reply to spam (as you did elsewhere), and if you do, don't quote the crap.

You didn't try too hard. Google almost anything to do with "PS/2 interface" and wikipedia is your first link:
Yes, that's how it works.

Typing - PS/2 interface computer keyboard - brought it up at the top of the first page in the Google search engine.
