It works! Thanks @pfalcon + @SpotlightKid

I'm able to get/post data to/from Google sheets and display on a Nokia 5110 + ESP8266.
I'll polish the code and share a tutorial soon.

The 64x32 one you linked to uses a HUB08 interface. I couldn't find much information on it. Alternatively, you could chain a bunch of MAX7219 (SPI) based 8x8 LED matrices to form a 64x32 panel (32x individual 8x8 modules) Here's a library I wrote for them, which I've combined to form a 32x32 panel (...

Make a get request using urequests.py from micropython-lib Copied this file to my board: https://github.com/micropython/micropython-lib/blob/master/urequests/urequests.py import urequests r = urequests.get('https://script.google.com/macros/s/(token)/exec') which redirects to: https://script.googleus...

I've been experimenting with integrating with Google Sheets and hit the exception: NotImplementedError("Redirects not yet supported"). To get data out of Google, you need to make a GET request to their /exec page, which performs a Location: redirect to the target page. The /exec page always returns ...

The frame buffer scroll is like a copy-n-paste, resulting in artefacts like you described. Try scrolling 5px or 10px and it should make the effect more obvious. The hardware scroll methods shifts the pointer to the display memory, resulting in pixel wrap around. You don’t have to scroll the entire d...

Another set of display drivers in my collection are the Waveshare epaper displays. https://github.com/mcauser/micropython-waveshare-epaper/blob/master/examples/2in9-hello-world/test.py https://github.com/mcauser/micropython-waveshare-epaper/blob/master/examples/4in2-hello-world/test.py I'm not subcl...

Have you seen @deshipu 's driver for the SSD1331 display?
It doesn't extend the framebuf, but may provide some inspiration.

Added subclassed version of my Nokia 5110 / PCD8544 driver: https://github.com/mcauser/micropython-pcd8544/blob/master/pcd8544_fb.py It uses the MONO_VLSB format, as there is currently no compatible Framebuf format for the vertical addressing supported by the display. More details on the display add...

I updated my Nokia 5110 / PCD8544 driver with examples of both inheriting and extending the Framebuffer. Inheriting / subclassed https://github.com/mcauser/micropython-pcd8544/blob/master/examples/framebuf_inherit.py https://github.com/mcauser/micropython-pcd8544/blob/master/pcd8544_fb.py Extending ...

I haven’t tried it but hotplot on github says you can generate a 38 kHz signal in hardware by configuring the MTMS pin as the I2S clock signal and setting the frequency appropriately.

Platformio code example here:
