Anyone working on SSD1283A display driver?

Hello, I've been looking for display for my ESP32 powered bicycle odometer and found this transflective display on aliexpress.
I am not new to micropython, but I've never written a driver for a display. Where can I look for inspiration?
Should I subclass FrameBuffer?

I even found the datasheet.

Thanks in advance

I would subclass framebuf. I'm not familiar with that chip, but I have written a driver for Sharp transflective displays.

Here is the driver. You might like to look at the docs - in particular the information about the VCOM bit.

They are rather odd displays. The resolution is great, the response time is fast, power consumption is tiny. But visibility depends a lot on the lighting. Yours is an ideal application, so long as it's readable under real world conditions.
