Grove is a modulated, ready-to-use tool set.
Much like Lego, it takes a building block approach to assembling electronics.

128x128 oled

Post by bobgardner » Mon Sep 17, 2018 10:55 am

I have several oled displays 128x32, 128x64, both spi and i2c versions. I bought the grove 128x128, and I can run the seeedgrayoled arduino sketch and see 12 lines of hello world in the 96 by 96 box, but thats not a very good example. It should at least be able to draw lines. The 128x128 display with the sh1107 controller is not a gray scale controller. Very confusing. I have been trying to compile a program using c to init the controller and fill and clear the screen in pagemode, 16 pages 8 pixels hi and 128 pixels wide. If any programmer out there with one of these displays has written an sh1107 init and clear and fill screen and maybe a setpixel and clearpixel using the sh1107 read-modify-write opcode pair, I would like to see a picture of the screen. Thanks. If Bill Yu is reading this, you asked me to send a picture of my display that says its version 1.1, and I sent a private message to you a while ago, but no reply so far. Thanks.

Hello again Bill. Did seeed build and sell a 128x128 1.12" oled v1.1? Thats what the picture shows. It must have a sino wealth sh1107 controller on it. Are the commands the same for all versions of this controller? I cant find a datasheet for the sh1107z. Do you have it? Can you put it in the documents folder for grove parts?

I have a 128x128. I clicked on the download button and I got a library for the 96x96. The sketches compile but nothing appears on the screen. Explain this to me. Is there a separate library for the 128x128?
