6 wires on that harness for the display. two of which are power and ground. that would lead me to believe that it's a serial lcd?
Quote6 wires on that harness for the display. two of which are power and ground. that would lead me to believe that it's a serial lcd?That leaves 4, way more than required for a serial interface unless they use hardware handshaking.Sniffing this would be a piece of cake IF you have a logic analyzer. If you don't you'd have to write something for your Arduino to do the job and that will be a task. That said there is at least one logic-analyzer-on-an-Arduino project around, I even think there was a post about it recently. I think it works with the SUMP client on your PC. That would make life easier.______Rob
git looks to have a 10 wire harness. i took it apart and noticed that the 4 buttons on the front panel had a handy 5 pin header and socket. (4 buttons, 1 common ground) this leads me to believe that the button presses are not serial and and the connect directly to digital inputs on the master module. that would leave 6 wires on that harness for the display. two of which are power and ground. that would lead me to believe that it's a serial lcd? (edit: i contacted the person who made that and the buttons do extend out from that wire harness.)
Basically you just identify the GND wire, connect that to the LA GND then hook the LA inputs to the other wires and start pressing buttons. Hopefully a pattern will become obvious. If not post a screen shot here and maybe we can figure it out.Also make sure the voltages involved are not too high for the LA.______Rob
and am still getting some noise n echos on unused lines
