Waveshare 1200x825, 9.7-In E-Ink display HAT for Raspberry Pi

This is everything it says in the description. The display is really sharp and the gray scale is nice. High contrast images look fantasic. Lower contrast images don't look as great, but this is no big surprise for a gray scale with 16 shades. It holds an image with power off for days (longer, but I don't have time to test it). The hat connects to a Raspberry Pi with no complicaion. The one thing that complicates using this is that the SW stack isn't super well explained. But it works. I ended up using soonuse/epd-library-python at github. The issue tracker has an issue by galev00 that oulines what it takes to get it running on Python. From there, you can display any image, using the test files as an example of how to display an image. In python, the pillow library can make it easier to draw text and lines to an image, and then to the display. Also, you can run the hat at 80 MHz, instead of 24 MHz, making the update of the display faster.
