@Jonaswinz, I'm now curious what role Espruino plays in that scenario?
I expect some parts use actual Espruino components..., and therefore, I assume you want to easily control the content of the display... and yes, for that, Espruino is an excellent choice... as long as you want an easy interface to put text and graphics out there with moderate speed.
With all these scanning drivers, flickering or smooth, continuous change are the issues, because you have to feed the data between scan lines have to be put out. ESP32 w/ dual processor helps if you can control the behavior regarding timing between the participating processes or tasks or what ever you may call them.
