Larger Keypads/Keyboards
Posted: Mon Mar 23, 2009 6:34 pm
I was wondering if it were possible to use some of the general purpose I/O pins to expand the keypad functionality. We have a requirement for full alpha-numeric support via a custom membrane keyboard (we already have a supplier of these). The ideal would be support for a 6x8 matrix.
We are currently using LK202-25 units.
