12864 Lcd with ST7920 controller

Hi there,
has anyone connected such display (
https://www.smart-prototyping.com/LCD-d ... 12864.html) to the ESP32? Is there some publicly available library or example code?
A quick search didn't produce any results. Translating some Raspberry or Arduino code shouldn't be too hard but I would be surprised if I were the first to try.
Best,
Daniel

It is not hard to drive such a display, but is it worth the effort, for half that price you can get TFT color display with touch screen ...

Hi loboris,
thanks for he reply. Connecting a TFT via SPI works but I still like the look of the monochrome LCDs. I gave up on this specific device nevertheless. It would need some modifications to run on 3.3v signals and the codeing needed seems a bit laborious.
If someone has an easy solution for the software driving a 12864 I would still be interested.
Thanks,
Daniel

Lately I've been using some ePaper displays which are excellent choice if you don't need fast refresh, and quite easy to interface ...
