Hi all:
I'm looking for specs on matrix keyboards. I am mainly interested
in their timing characteristics. I have looked everywhere on the web,
and I can't seem to be able to find any design specifications on matrix
keyboards. If someone can provide me with a starting point it would be
greatly appreciated.
Thanks
