E-Paper 4.2 Color does not update properly #4957

The problem

Hello,

I have a problem with an e-paper display.

The update takes a very long time and approx. 8 minutes even though the update rate is set to 2 minutes.

I also placed the pins correctly and also selected the 4.20in-bV2 display, which also updates normally, but here only a red screen is shown without text or anything else.

The functions "reset_duration" and "update_interval" have already been selected for various updates, without success.

Any Ideas ?

  1. Waveshare E-Paper 4.2 Color
  2. E32 Driver Board
