Waveshare 13,3" error at new cycle
The epd displays the modules at the first start, but it doesn't refresh, and when starts a new cycle it stops with error.

Thanks for reporting this issue @kalalaa . It seems there is an issue with the driver file of the 13.3" display. This driver was copied from waveshare directly, but I'll a look into this at the end of today

@kalalaa Hi there, apologies for getting back at this rather late. Have you tested this with the latest version of Inkycal? From the looks of it i.e. display updating once, but not after that, this was an issue with the earlier version of InkycalOS-Lite v2.0.4, which was corrected a few days ago.

Please let me know if it works for you. If not, please paste the full traceback as you have before. Thank you in advance

Hi! The issue is still the same with the latest OS:

source venv/bin/activate

Hi, I have the same display as mentioned above and I am running into the same error. Is there any fix for this? Thanks in advance!

My only fix was this
(crontab -l ; echo "@hourly cd $HOME/Inkycal && venv/bin/python inky_run.py &")| crontab
But i think i set it every 4th hour...
So every 4th hour it starts, refresh the display and exits with the error. But the next 4th hour it starts again...
