InkyDev - UserWarning: Busy WAit

Support
1

I have the Inky Developer (7 color e-ink display).
I used code from examples and was able to get it to render… twice.

For some reason, now it does not render. I get this error:

I run this example:
python display-7color.py

and get this error:

/home/me/code/inky-playground/.env/lib/python3.9/site-packages/inky/inky_uc8159.py:303: UserWarning: Busy Wait: Held high. Waiting for 1.00s
  warnings.warn("Busy Wait: Held high. Waiting for {:0.2f}s".format(timeout))

  warnings.warn("Busy Wait: Held high. Waiting for {:0.2f}s".format(timeout))

Any clues?

I bought the same screen and I got this error at the first try.
I have no clue how I could fix this…
