    I wired mine up exactly how it is shown in the pong clock app note. when I try to give it power it starts to draw more then one amp with my power supply at less then 3v. I’ve checked my wires a few times to make sure they match the schematic on the app note.
    Is my LCD dead?

    I’ve been having trouble with the Screen resetting when I try to move objects that I’ve drawn on the screen. It will reset after a couple of seconds some times sooner. I’m using the serial com of an HCS12 @ 38400 baud and the backpack vcc is at ~7V. Everything is has a common ground too. I’ve also tried varying delays before sending the commands too redraw the screen and turning off the back light.

    I’ve been playing with this for a while and am starting to think there might be a problem with the backpack. I seem to get a an endless stream of random characters and symbols showing up on the screen. Also the potentiometer is very sensitive i.e. if I tap it I wont be able to see any of the streaming randomness.
    So far I havnt been able to get it to do anything by sending the commands (‘|’ (command)). I’ve tried with the serial coms on my HCS12 microDragon, and my Boarduino boards.
    Does this sound like I have a bad backpack?

No public wish lists :(
