Hi there and welcome to Inkycal. Thanks for opening this issue. As this is your first issue in this repository, please read through the contributing guidelines |

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: |
|
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 |
|
I've got a fix ready for this, but unfortunately no way to test it myself as I do not have the exact same display. cd Inkycal
source venv/bin/activate
git pull
git checkout bug/#368
python inky_run.py
# Check if two updates can run one after anotherPlease let me know if this works for you or if it doesn't work as expected. |
