    I am trying to use a GLCD, a WDG0151-TMI-V#N00 on my EasyAVRv7 board and I realized that I might need some help. The MPU I have is an ATmega32. Problem is, nothing works. For example I can't even tell if the GLCD is open or not in the photograph that I attached. I am attaching a picture of my development board in case if I have erroneous pin configurations. Also, I am attaching a file containing my code. Thank you very much in advance.

    Ahhh, I see it. Your dev board is upside down. ;-)
    Does this board have a debugger? If so, step thru each and every instruction that talks to the GLCD and observe the signals are all correct for each routine. Once you verify each routine then you can look at how they interact. Measure at the pins of the GLCD and not the controller.

    Back when I used one of these I don't remember "opening" the device. I just wrote to it. It is simpler then the alphanumeric devices in this respect.
