Busy Wait error - Line 323/333

[KRuddPM]

Had my Inky Impressions working for weeks, and today I've loaded the script up and I'm getting the following error:

/usr/local/lib/python3.9/dist-packages/inky/inky_uc8159.py:323: UserWarning: Busy Wait: Held high. Waiting for 0.20s
  warnings.warn("Busy Wait: Held high. Waiting for {:0.2f}s".format(timeout))
/usr/local/lib/python3.9/dist-packages/inky/inky_uc8159.py:333: UserWarning: Busy Wait: Timed out after 0.20s
  warnings.warn("Busy Wait: Timed out after {:0.2f}s".format(time.time() - t_start))

I have looked through the Issues here, and tried adjusting the timeout on the inky_uc8159.py script, but I still get the same error.

I have the Inky connected directly to the PIs GPIO pins, with no other IO.

Any help would be appreciated.

Did you manage to get anywhere with this?

Any progress on this issue or a related issue?

Same issue here, using a Raspberry Pi 4.

So, recently the issue was resolved for me by changing the RPi board. Originally used a Zero 2W but then switched to a Pi4 and later to a different Zero 2W. Worked on both of them. I suppose there was likely a short on my gpio that caused the busy wait error.

I have the same issue on a Zero 2W too, I don´t think it's a short issue, more likely performance bottleneck?

No I’m certain the reason was a short, I tried with a second Zero 2W and it worked. I also found the short on the gpio pins. I still do get the busy wait error but it uploads just fine, so I recommend you just try it with another rpi too.
