AnyCubic Vyper LCD improvements

[ngraziano]

Description

Various improvement for stock AnyCubic Vyper display.

Requirements

This PR need a standard Anycubic Vyper. The screen must have stock DWIN_SET firmware V2.4.5 (last from anycubic website or include in Configuration repository)

Benefits

• Make temperatures work on main page
  Fix the same think that in PR Anycubic Vyper - compile fix, home screen temperature update, power fail display fix #26261
• Fix the color change in file selection page
  The color was not changing when selecting a file and the filename was disappearing.
• Show getFirmwareName_str() in the About page
  instead of "V2.4.5" of original firmware it show the marlin version
• Use an empty field in original screen firmware to display message on main screen
  In the original screen there is a field of 30 character long in the middle top of the screen, I use it to show standard printer message
• Fix the fact that the screen go black on reset (fix from Anycubic Vyper - compile fix, home screen temperature update, power fail display fix #26261)
• Add a tweak from Anycubic Vyper - compile fix, home screen temperature update, power fail display fix #26261

I do not include set_brightness from #26261 because I do not see the need, the default brightness never change.
I do not included fix from #26261
I have put all in one PR but I can split it if necessary.

Configurations

The configuration needed is the the one from example https://github.com/MarlinFirmware/Configurations/tree/import-2.1.x/config/examples/AnyCubic/Vyper

This PR should replace #26261

We host a DWIN set along side the Vyper configs, but I think they're the same version. Have you confirmed that your changes work with these?

Fixes should not be pulled in from other open pull requests.

Ideally, you'd collaborate with Bob-the-Kuhn over in #26261 so we don't have competing or duplicate changes.

I have just check the file are identical (binary diff) so my modification are compatible.

Fixes should not be pulled in from other open pull requests.

Ok I will modify (in a few days) the PR to keep only new modification that are compatible.

The part "Make temperatures work on main page" take another way to fix the issue, I will keep it separated and I will discuss it on the #26261.

[ngraziano]

I have update the source to only include independent fix.
I update the main description accordingly with Strikethrough for removed part and Italic for added part.

As long as we're in this area, might as well ensure that AVR boards using this display store their strings in flash, apply the MString class, and find any other instances of redundant code that can be made into little helper functions.

[thinkyhead]

This now builds with the example configurations, with sufficient MString sizes to suppress warnings. I tried to keep everything working exactly as before, but string alignment or other issues could exist, so please test on a real screen and let us know if there are any issues.

I have test on a real vyper and I had the following problem with time and print rate :

I have manage to fix it.

Related question... does the Marlin-generated firmware binary work for you without renaming it?

From my comment over in #26261 (comment):

One issue that has come up several times on Discord is the firmware name. The current format of firmware-20240512-012214.bin will not flash, but main_board_20240512_012214.bin will. It has to have the main_board_* prefix and no dashes/only underscores for the bootloader to pick it up. This also matches the naming convention of the community fork (though, they don't use a date).

No, I need to have main_board_*.bin for the name.

But I am not sure if it impact other model of printer so have not pushed it.

But I am not sure if it impact other model of printer so have not pushed it.

As far as I can tell, the Vyper is the only machine that uses this motherboard/environment.

The fixed firmware naming can be pushed to a new PR so it doesn't muddy up this LCD-only PR (making it easy to revert later if it does become an issue).

[thinkyhead]

Thanks for the patches! If that takes care of all the display issues then I'll merge this forthwith.

[ngraziano]

I find a last place where feedrate is sent as float and correct it.

All is good now. You can merge when you want.
Thanks.
