SSD1322 Oled Display with a Pico?

Post by ChasL001 » Tue Apr 13, 2021 12:36 pm

I have an SSD 1322 OLED display which I have used with a Pi Zero for a model train display of timetables. The display works OK but of course all the programming was done by someone else and I just followed a build guide.

I'd like to try and use this display with a PICO using SPI.

I followed a great YT video https://www.youtube.com/watch?v=zlKJ5hvfs6s showing how to test I2C and get a display working but it was a different display to mine.

Doing a lot more research I discovered I needed to install the LUMA Package which I did and have luma, luma.core and luma.oled all installed via Thonny manage packages. I've tried running the I2C detection part of the tutorial https://electronoobs.com/eng_arduino_tut138.php which works when checking my BME280 board but does not when using the SSD 1322.

So I guess I'm not loading the SSD driver correctly. I've tried following the guides at the website https://luma-oled.readthedocs.io/en/latest/install.html but of course this all relates to Python on a Pi not Micropython.

Can anyone help with this in any way?

With thanks, Chas.

Looking at the SSD1322 data sheet, I2C is not mentioned. It talks about serial SPI, and parallel 8080 and 6800 mode.

Gosh darn it, you're right! I made the assumption they were commonly connected for both but the package only talks SPI not I2C.

Right, new display SSD 1306 required for the project.

Thanks Robert :)

SPI is also available at the Pico.
