I have the following lcd (DisplayTech 128x64 COG STN Y/G) unfortunately after reading the data sheet I still have no idea how to hook this up with an arduino. Could someone either assist in explain how this needs to be hooked up and how you would interface with it once connected.
It uses a ST7565R controller from Sitronix.
Use the controller datasheet.
On pages 38/39 you can find reference examples for the voltage generator connections an on page 66 you find the MCU connection examples.
