Solved my problems with Wemos with E-Paper display

I am building a project with Wemos and an E-Paper display. Not enough gpio after connecting the display (epapers spi interface used 6). I came across a wombat and it was just what I needed. E-Paper also takes a relatively long time to update, making it difficult to eliminate key bounce. Wombat solved this problem and I look forward to using its other features in future projects.

Pros
  • Decent performance
Cons
  • Minor problems
