1 year ago @lukasMega Thanks for opening your first issue on Inkycal 💯 . Glad to hear you like Inkycal 😄
Thanks for all the profiling! Indeed I did not know about these, but I had a feeling that there still is lot which can be improved. While generating the images, the load is dependent on several factors, including the selected modules and e.g. size of the calendar file.
Currently, the script doesn't "wait" while running non-stop but instead invokes the time.sleep() function of python, which still stresses the cpu. A better approach would be to use timed threads instead of sleep, but this is a bit complicated and I only recently learnt about it.
If you have suggestions in regards to reducing the cpu stress by e.g. changes in code, please do share them. Any help with reducing the cpu stress is most welcome.

1 year ago I don't think that using sleep() function is wrong, also it don't uses CPU time.
I did small update: I disabled (commented) inky.test() in inky_run.py (https://github.com/aceisace/Inkycal/blob/main/inky_run.py#L6):
~$ date +"%T.%N"; time sudo python3 /home/dietpi/inky_run.py ; date +"%T.%N";

1 year ago inky.test() only tries to generate all images once before the actual run. This is useful if you e.g. changed your config and Inkycal doesn't work anymore. So the test is actually not required. Depending on the display's size and supported colours, the time may increase or decrease too.
Looking forward to your enhancements when they are ready. When they are, please create a PR pointing to the development branch. Closing this issue 👍
👋 First of all, thank you for this project! Very nice and useful idea! :) 👍
Description
I'm using Raspberry Pi Zero W (1-core CPU) and inkycal python scripts takes ~3+ min (I see 100% CPU usage approx. ~3¼ min)
Notes
💻 My configuration / environment
Inkycal was installed: August 2022
HW: Raspberry Pi Zero W
Memory card: [I will update later]
OS: minimal with no GUI - DietPi (debian 11, kernel 5.15.…)
installed additional packages: only those required for inkycal + htop + avahi-daemon
RAM usage: ~23 — 80 MB (with running inky_run.py)
ePaper: Waveshare 7.5" (800x480) most probably rev. v2
ℹ️ I know, it's old and slow hardware, maybe it's nothing to improve. I will try to put here some more useful information from my investigation.
