Sure.
An associate of mine has asked about the possibility of adding RFID cards to the alarm systems he installs, as he has had some enquiries from customers.
My plan is to have a PIC read an RFID card and have the PIC drive a crosspoint switch wired accross the alarm keypad to "simulate" keypresses.
I have the reading and driving all worked out but now need a Xpoint switch so I can design a PCB (size constraints).
As a "just in case" I am looking, this weekend, at using 4066 chips (3 of them) connected as Xpoint array 4 X 3.
With the difficulty I am having finding some, that will probably be the solution.
See?
Simplicity itself huh?
(Well it is after getting some help on some problems from people in this very good forum.)
I've got the code basically sorted out (it works on my Development board, anyway) and am just waiting now to do a cuppla PCBs.
And NO, I cannot get any information from the manufacturer regarding their LAN format for the keypad to panel comms.
I have had it displaying on a terminal, but I cannot make any sense out of the data I see going back and forth.
The keypad and panel are both built around PICs.
