Here we have input to standard home screen on TI-83+/84+((C)SE)'s from a standard PS/2 or USB keyboard.

It can navigate to any screen with the press of a button or 2 and can type any input-able character to the calculator, program it or enter notes.

This is just a quick test to show the starting point of testing.

ArTICL arduino library is being used at present, and thanks to people here for answering questions .

I have set the video in the first link here to download, so that you can actually see what is going on, on screen. The second link will let you view online and may not be clear.

Great job!

Good work! I'm glad you could get a demo working! It might be time for me to update my old keyboard video for the CE.

Glad to hear it! How does it support both USB and PS/2 keyboards? Or are you supporting PS/2 keyboards that plug into those passive USB converters?

Well the Keyboard I have used has a USB plug, and it connects to a USB socket PS/2 plug adaptor. The arduino has a PS/2 socket attached. It works with keyboards that have the ability to send both PS/2 and USB signals, it expects PS/2 signals.
