Not robotics related, but you guys are the right ones to talk to about this. I'm working on a security system project. I plan on replacing the Moose Z1100e central control unit with one of my own design but want to keep the keypads. They communicate using an unknown serial protocol. There's no info on the web about this protocol. Both the central control unit and keypads are functioning, so I can monitor the serial lines. I am considering using my dual channel storage scope to monitor the send and receive lines, except 2 things I'm concerned about - the limited capacity of the storage scope (one screen worth of data) and the fact that Ch 2 on my scope is flaky. Does anyone have any other ideas? Has anyone done a uC project to act as a logic analyzer? I would like to do this without spending alot of money (which would probably be a first for me).
