Review on Waveshare 7.5inch E-Ink Display HAT for Raspberry Pi – 800×480 Resolution, Embedded Controller, SPI Interface, Support for Raspberry Pi Series Boards and Jetson Nano by Nick Tucker

The documentation/sample code provided is often incorrect and contains typographical errors. Information/commands have been edited and entire sections removed in the provided datasheets. After I wrote my own firmware it worked fine (and it supports greyscale, one of the edited features) but after about a month it just stopped working (despite meeting specs and hibernating the display after each update) .
