Assembled the Iduino(s) today, hooked up the display and tried to upload the software. The display is not showing anything. (It will show a line of full squares, then cycle off.) I have checked the wiring, connections and the code for the LCD control. I am using the GDM1602k from sparkfun.

The IO light is flashing nicely. so I know that the program is running. Do you need to not have that on?

EDIT:
I removed the LED, still no luck. I have it compiled with debug, and it does print the "OpenGauge MPGuino online" message to the serial port. but still nothing coherent on the screen. Full squares, horizontal lines on the top row. nothing more.

First, try turning off debug, and reload it. Then when it comes up hit the middle button (and nothing else) several times and see if the display improves.

No good, it looks like a hardware issue? I had tried to put serial debugging in earlier, it showed me that it was going through the steps. However the display is still FUBAR. (Top row only, solid blocks or single horizontal line.)

Yah, gotta be. If you have an ohmmeter, unplug the guino and check ohmage between all the LCD pins. Except for pins 1,5,16 they should all be at least 10k ohms apart.

Just wondering... how are the pins supposed to be numbered on the display? from the display side or the back side? I just saw the +- pins and assumed they were 1 and 2. I think I found the 1. (The thing is backwards!)

When looking at it from the front, the lcd connectors should be on the upper left. pin 1 should be all the way on the left and pin 16 should be all the way on the right when viewed from the front.

Works well now. (Reversed the pin-in for the display.) I LOVE vacuum de-soldering tools.

Tomorrow: The rest of the parts.

Saturday: Install

I'm not sure how the IDE works in this case, but is the size increase due to different compiler specs or what? Also, do the newer IDEs drop older hardware support (i.e., the one that has been in use here)?
