Hi, i am using NJU6676 controller based Optrex 128x64 lcd, i found your code very helpful.
I am running this snake application.
I am not getting clear vertical line movement, only horizontal movement is fine. As per the above diagram mentioned by you, the vertical line is clear, where as in my case thats breaking.
I wonder, if u can help me in solving this, i suspect the problem is with reading of Display Data RAM of the graphics lcd.
i tried may ways, as per the datasheet timings, generated that sequence of control assertion. still the problem remains.
Can you tell the Dislplay Data Read sequence.
