Do you have any examples of how to hook up a keypad to the Graphics Master?

Thanks, Bill

Hi Bill. We have a keypad cable drawing for a 4x4 Grayhill keypad. I've posted the link below. This cable is based on the serial port cable (610110-4007) included with your development system, which you can adapt for keypad use. You might also take a look at the keypad post in the ADSmartIO topic.

The keypad used in this example is Grayhill 96BB2-006-R (or -F). It's a 4x4 keypad with keys labeled 0-9, A-D, *, and #. This keypad is useful when prototyping a system that will use the keypad scan. You can configure two or more in a matrix to simulate larger keypads.

Here's what the keypads look like (these shown are for front panel mount):


Keypads like these are useful for prototyping, but generally don't meet most applications' requirements for layout or labeling.
