I2C 128x128 OLED


#1

Hello! I have begun work on building a lisp computer based around the esp32 feather and a 128x128 OLED display
https://www.adafruit.com/product/4741

I have tried modifying the code from here Simple data plotter for 128x64 OLED display

But I can’t seem to get it.
My code is available here https://git.ablecorp.us/able/ulisp/src/branch/trunk/ulisp_feather.ino

The “simple data plotter” article will only work with a display that uses the SSD1306 driver chip. The one you’ve got uses the SSD1327 chip, and the mapping of the display memory to the screen is totally different; it’s a greyscale display, with one byte per pixel.

That should actually make it easier to drive, because you’ll be able to plot a single pixel at a time, but it will involve doing some coding!
