not going so good... anyone knows about other libraries for this LCD?
Well, at least u8g2 is the only library for the T6963 which is mentoned in http://www.arduinolibraries.info//libraries.
The problem is, that another a lib will not really help you with the hardware and the wiring problems. You definitly need to solve some hardware problems before using any lib or writing your own code.
rotation, enable, dc, cs?
Rotation argument is described her:
But just have a look at the examples and takeover the default value.
enable, dc, cs: These are the signal names as they are called in u8g2. I have choosen generic signal names for u8g2 and of course each datasheet has different names. Thats also why I suggested to make a mapping table.
I tried do document this here:
Maybe you have a better idea how to make such things more easier to read. But connecting such a GLCD (especially a T6963) is not that easy and requires some reading. I am always happy if you name a different lib which does this job better.
Anyhow, let me start the mapping table for you:
| U8g2 Name | | GLCD Pin Name | | Connected to Arduino Pin |
| - | - | - |
| enable | /WR | tbd |
| dc | A0 | tbd |
| cs | /CS | tbd |
| reset | /RES | tbd |
Table is not complete, you need the data lines also (D0..D7), but I hope that this is obvious.
Of course I do not know to which GPIO pins your display will be connected, so the next step will be, that you connect your display to some GPIO pins. Write down the pin number in the correct row (replacing "tbd") and use these pin numbers in the constructor arguments (just like for the LiquidCrystal lib).
But I think the more complicated part will be the power supply as specified on page 7 / section 7 of your refered datasheet: You need to get a -25V power source.
