/* Simple firmware for a ESP32 displaying a static image on an EPaper Screen.

*
|

|
|
* Write an image into a header file using a 3...2...1...0 format per pixel,
|
||
|
|
* for 4 bits color (16 colors - well, greys.) MSB first. At 80 MHz, screen
|
||
|
|
* clears execute in 1.075 seconds and images are drawn in 1.531 seconds.
