What better first test that Comic Sans MS 😅
Stick this in your DWIN_SET and let me know if this works
Comic Sans Font.zip

@gothcha I am trying to comprehend the DWIN development PDF
and I think the info on page 10 says that the user data is stored in sections 24 through 127 of the flash memory in 256KB (the 26KB shown is assumed to be an error) chunks. I would think this supports your file size estimate.

I am still struggling with how the display reads in the files of the DWIN_SET folder. Maybe if I read the PDF a couple dozen more times something might click.

Do you think the font file should be renamed '0T5UIC1.HZK' per the Kernel Application Guide?

[gothcha]

hehe yes I am at the same point. It is very confusing how much memory this particular display has. It may be that the file is being loaded but the font that is being called up is still the internal default?

Maybe a change is required to the firmware to address the correct one.

[gothcha]

I understand that the leading 0 is the font number and the filename is optional so it shouldn't make any difference

Ill test when im home

I've setup a repo with my experimental codes for creating new .HZK Font files: https://github.com/Quint097/DWIN_Font_Files.

I've basically written the reverse of the decode.go file provided by @enigmaquip. It translates typeface table pictures back into binary and inserts them into a copy of the existing font file. this way it rewrites only the parts we want and leaves the rest untouched.

[adam3654]

@Quint097 I tried all three of the hzk files from the repo folders. I reformatted the card 4k as directed every time. I also tried solo in the DWIN_SET folder, and with the rest of the display firmware files from Jyers repo. I can't really think of anything I could be doing wrong. I use the custom icon set from Jyers repo.

@adam3654
Can you create a issue on the issues tab on my repo? That way i can hopefully help you better.

[Quint097]

@adam3654
Might it be that the files just didn't download correctly?
Maybe try these: HZK Font Files.zip

[enigmaquip]

@Quint097 first commit was basically a proof of concept. I've since pushed fixes for the font being undersized and fixes to vertical and horizontal spacing. It's way closer now to a final solution.

@Quint097 The Droid Sans Mono worked from the zip. That's weird because I had downloaded the font files multiple times last night/this morning and they all failed.

Thank you for the help!

[Cal-LF]

That does look better. I would like to try it when you get it sorted out. Maybe post it in a zip.

[Cal-LF]

@Quint097 The date on the files is from yesterday.

[Quint097]

@Cal-LF
Yes, that's when i fixed it.

@Quint097 Flashed successfully and it looks nice. Your hard work on this font project has made the display easier to read. I do appreciate this improvement.

@Cal-LF Thanks!

By the way; I'm sorry if I'm sometimes a bit blunt with my answers, I'm not the best at communicating via text.

[Cal-LF]

LOL. We aren't writing resumes or love letters.

[Quint097]

If it's alright with everyone, I would like to move any font related issues, questions and discussions to DWIN_Font_Tools to keep things organised.

I have created a discussion threads on the new release, so any questions or issues related to that can be posted there.

[Cal-LF]

I will follow from your Github.

[Jyers]

@Quint097 I'll link that around where appropriate 👌
