So, I've got my fingers on some Xplained Pro boards and some extension boards to them. Specifically the OLED Xplained Pro board.
Any of you guys got a OLED Xplained Pro up and working? Where did you get the info for accomplishing that?
Thinking I should be a good boy, I thought I'd start out with reading up on the data sheet for the display. To my surprise says (here) this:
The datasheets for the display module or the display controller is not publicly available and has to be acquired from the respective manufacturers.
A few sentences earlier than the above quote it says:
OLED1 Xplained Pro features a 128 x 32 pixel white monochrome OLED display, UG-2832HSWEG04 from WiseChip Semiconductor Inc.
Trying to follow the above link, all I get is a Chinese 404.
Of-course, Googling for "UG-2832HSWEG04 data sheet" gets you to the usual data sheet sites. I found (at Adafruit) one data sheet, 26 pages, with the usual hardware descriptions (electrical signals, maximum values, physical dimensions and optical performance etc) and one page with an example of instructions on page. One example. One example. Is that all that is available??! No "reference"? No list of accepted commands?
How should I interpret e.g. a box in that flowchart with the text "Set Entire Display On/Off 0xA4"? Will that set it on, or will it set it off? Or will that toggle the on/off state? (No, I seriously don't believe that.)
What about the box labeled "Clear Screen", and nothing else?
The example is covering "Initialization". That's a start, but how do you actually send display data to the device? Not a hint about that as far as I can see..
That data sheet sucks worse than most other Chinese DS'es... (I can understand if you need special permission to get that data sheet out of the doors of the manufacturer of the display. I would also be extremely embarrassed if I had something like that "hit the public"...). And how did the people at Atmel reason when they chose this for an evaluation kit?
