For a small project I wanted to make use of the lcd plug. After assembling the plug and connecting it to a JeeNode, I uploaded the lcd plug demo and... it didn't really do anything.
I checked that the JeeNode and LCD work just fine. With an external power source I also checked the backlight was working as intended. Also my multimeter shows that there seems to be a signal coming into the board and I registered pulses on some of the pins. The soldering seems to be just fine, so I'm suspecting either I overlooked something trivial, did something really stupid or some part of the plug isn't working as it should. Did anyone have similar problems, or tips & ideas on how to find the culprit here?
