Re: Supporting a PS/2 Keyboard

Anything is possible, but it seems like there would be a lot of little
gotchas that you'd have to implement in software running on the main
processor. You could just put an 8042 in there; there's a driver for it in
Platform Builder.

I don't understand what passing the codes from your device to the serial
port has to do with how the keyboard codes are arriving. Am I missing
something? Are you saying that you need something at a different level than
what an application running on the device to which the keyboard was
connected would get?

Hi everyone,

Is it possible to have a PS/2 keyboard connector interfaced directly to
the Intel PXA270 (via GPIO pins) and leverage the existing KeyBD driver
to get scan codes from the keyboard? Obviously there's not an 8042
keyboard controller in the chain so I don't know if its possible to do
this. We have an application which basically is supposed to grab the
raw codes from the keyboard and passes them over a serial connection to
another application.

I'd appreciate any comments or suggestions any of you may have on this.

Thanks.
