T. Jackson & Mr. E,
Nice work to both of you regarding Matrix Keypads!
I have used Trents example with great success, I plan on trying out Mr. E's with a handheld Wireless panel/LCD I put together for work. I want to add a 4x4 matrix keypad to the front of the reciever case and upgrade my TXM/RSM LR LINX modules to the new LT tranciever type. I really think having the matrix keypad will expand (the crap out of) the types of commands I can send.....wall mounted reciever, robot, whatever....
