This project is based in part on, and contains code derived from, the OpenX4
E-Paper Community SDK (https://github.com/open-x4-epaper/community-sdk) and its
community device ports (M5Stack PaperColor, Murphy M3, and the
community-sdk-de-link ESP32-S3 port). In particular, the SSD1677 and UC8253
panel initialization sequences and waveform LUTs are derived from that work.
