Matrix kbd and OFBiz Internal POS

[lincolnkendal]

Our convenience stores need to use matrix keyboards.  My understanding is that I need code to translate keycodes to product ID's.  Is there documentation on how to use a matrix keyboard for product ID's in OFBiz?

the matrix keyboard sends a hexadecimal code.
usually there is a driver that converts that code to a mouse position,
or sequences of keyboard strokes.
Not sure that will be a easy case since not all the Products show on the
 screen at once.
you may have to program key sequences to do lookups from the key pad

Not sure there are any OFBiz docs on this but if you dig around the
buttonevents.xml, ButtonEventConfig.java and Keyboard.java in the pos
module you'll see reference to an attribute of type "key-code" (for
buttonevents.xml) and you'll find it's linked into the jpos results of
getPOSKeyData which seems to return a potential hex value.

Never used a matrix keyboard myself but from that quick look it seems
the underlying support is in the POS module.
