Hi
I just tried it with the Display Test code from the examples folder.
I didn't implement g8ulib it in my code befor I know if its working properly.
So my main problem is how to set the pins right because the constructor is gifing
11 pins -> 8 Data and cs, da.
To get the Display working properly i need to manage:
CS -> Chip Select
DC -> di -> Data/Command Control
WR -> Read/Write Select or Write
RD -> Read/Write Enable or Read
Reset -> reset -> Reset / init
My updated example code looks like this:
#include "U8glib.h"
// setup u8g object, please remove comment from one of the following constructor calls
// IMPORTANT NOTE: The complete list of supported devices is here: http://code.google.com/p/u8glib/wiki/device
