Keypad broken?
Keypad broken?
I have an MX212 and I use LCDC and the screens work great. I can't do anything with the buttons though. I have tried adding them as events, but nothing happens.
I tried going to configure/test to see which parameters the LCD sent after I pushed a button, but nothing happens. I tried using hypertermnal and connecting to my mx212, but nothing comes up when I push a button. I tried reinstalling the drivers, tried plugging the lcd into every USB port on my computer with no success.
What am I doing wrong?

Is the keypad plugged into the LCD properly? Does the LCD send it's version number to LCDC when you connect to it in test mode?
The keypad header connects directly to the PIC so it's difficult to imagine the controller being at fault and the rest of it working... it's equally difficult to imagine the whole keypad being b0rked - though I guess that's possible?
Have you updated your USB driver with the one posted on the forum? http://www.lcdforums.com/forums/viewtopic.php?t=1016

Alright well I found the problem was the plug on the back of the LCD was loose. If I move it around to just the right spot, the keypad works again. After about 10 min or more the keypad will stop working again and I have to readjust the plug on the back. I have tried taping it so it doesn't move, but after awhile I have to readadjust the plug for it to work again. Should I return it and get another LCD??? This is really annoying because everytime I want to use the keypad I have to open up my case, and readjust the plug on the back.
Personally I'd bend a few of the keypad headers pins a little so the plug is a little tighter in fitting - but that's the kind of guy I am
I'm sure MO will arrange to swap the keypad (or the whole thing) if you can't fix the problem...
