ps2 keyboard basics

ps2 keyboard basics

2005-08-17 by Lupe

Hello all, I am in need of some basic assembly code for my ps2 
keyboard to 8515 micro project.  I do have some code but it is way to 
long for my level of expertise and obviously won't work.  If I can 
start with a very short example, I believe I can expand on it. I just 
need something very basic that I can compile and step through with 
avrstudio so I can understand it better and expand it with all the 
bells/whistles. One more thing that I would like some opinion on.
Does it make sense to use the Rs232 spare port/hyper-terminal as a 
sort of debugging tool for the ps2 keyboard as apposed to the lcd
that I have connected to the micro. Any help/comments would make my 
day.

Atmel has application notes regarding AT keyboard interface both in assembler and C. Dont remember if they are for 8051 or AVR. Look at Atmel.com
Regards.
