It looks like the 3in7 display does not conform to the same standards as the other displays. I should have caught this when putting together the documentation.

I'll see if there's a way to patch around this and fix this up without too much of a kludge. I have a few ideas. Would you be willing to run some tests for me once I have something that might work?

Of course!

@ZubaZ21
I think I have a solution; I've done a bit of a kludge on the base library that runs this to try and fix the issue.

The tgz linked here can be executed with ./Screen

When prompted, enter your screen type to run a demo. If all goes well, you should four different versions of the same text displayed sequentially in different orientations. If it fails, share the debug output here and we can go from there.

from epd_display.

ZubaZ21 commented on June 4, 2024

Output was displayed.
Of note (and it may be as intended but I don't know clearly what was being tested): The screen was not cleared before your test ran or between the changes or orientation.

Lastly, thanks for finding an issue and not making me feel like a damn fool.

txoof commented on June 4, 2024

@ZubaZ21: Well, that's progress!

It should have displayed the text in four different orientations, clearing the screen between each redraw.

I suspect the 3in7 screen also has a weird clear function from the other screens. I suspect I can sort this out too. Can you share the debug output (all of it)?

Thanks for testing this out. It's super helpful to get feedback. Sometimes folks leave trouble tickets and never follow up so the bug just remains open forever.

ZubaZ21 commented on June 4, 2024

Happy to help.

For what it's worth, the demo provided by waveshare clears as expected.

Ummm... is the debug write to a log? Or what's the best way to output?
(Or I can just copy/pasta?)

from epd_display.

txoof commented on June 4, 2024

Yeah, you can just copy paste from the terminal output. There's probably several screens worth, but I'll take it all. You can make it easier to read by surrounding it with three back ticks (```) before and after. That will make it fixed width and easier for me to read.

It will look like this when you post the comment.

In other news, the reason my code doesn't work properly is because the waveshare libraries are GARBAGE. The clear method has two unneeded arguments in it that are causing all the problems for your screen.

I think I've found a quick fix that should improve things for all the screen types.

I'll work on building another test bed around that and share it with you shortly.

If you're on discord, we can continue here:

txoof commented on June 4, 2024

Here's an updated version of the demo -- This version should handle the clearing properly.

Once we get that ironed out, I can build paper_pi against the library and push out a version that will hopefully work for you.

from epd_display.

ZubaZ21 commented on June 4, 2024

Latest build. No love (or rather, the same love); no clearing of things.

I had a flash of insight while I was eating lunch: my insight was different wrong. Back to reverse engineering the craptacular driver file.

I'm beginning to think it might just be easier to rewrite the entire driver stack and start from scratch. The waveshare libraries are a maze of unused arguments, poorly named functions and duplicate chunks of code.

This will be a fun project...

I've started building my own set of drivers based on the spec sheets. This is helping me have a much better understanding of how the drivers work so I can hopefully trouble shoot this problem.

There's a lot of copy/pasta going on leading to redundant chunks of code in the drivers and stuff that's got fat-fingered once and has propagated through all the drivers. Or, the spec sheets are wrong. Equally possible that WaveShare maintainers don't read their own spec sheets, so that adds a whole fun level of

It could be a very long road before I manage to get to the 3in7 rewritten. I hope this doesn't dash your hopes completely.

I. AM. FURIOUS. ;) Good luck. Have fun. Learn all the things. Let me know how I can help.

I've learned a lot, and maybe have an updated demo that might be ready to go.

Can you give it another try?

I'm gonna have to call uncle on this one. Without a 3in screen to test on, I'm just making guesses at this point.

In a fit of frustration, I even looked around to buy one, but couldn't find one for sale!

If you're interested in an upgrade, the 5in and 7in models are really nice and I've verified that they work with the EPD library that backend this project.

Understood. If you are ever interested, this is the one I picked up. https://www.waveshare.com/product/displays/e-paper/3.7inch-e-paper-hat.htm Maybe this is how I learn python and drivers. 😂 It was good to meet a fellow Aaron. Aaron www.todaysagoodday.com

If you have some programming experience, python is dead easy to learn. If you're new to programming, python is a great language to start with too.

If you want to give it a go and have a fiddle with the epdlib, this would be an interesting project. There's nothing too complex going on in the epd library. I can coach you through the important parts.

The WaveShare demo code is documented reasonably well so you can get a feel for what's going on. It's a good place to start playing around too.
