Optional Large/Fullscreen Bootscreen for TFT_COLOR_UI

[thisiskeithb]

Description

Allow users to enable large/fullscreen bootscreen for TFT_COLOR_UI. Due to the large file size, this cannot be enabled by default for all boards with 480x320 TFTs.

320x240 had the fullscreen bootscreen enabled by default, but was changed to the smaller bootscreen for consistency. This can easily be reverted if we want to retain the large bootscreen on those screens.

Tested on an Anet ET5X with Anet TFT35 & TFT28.

Benefits

• 480x320 TFTs can now use the large bootscreen by disabling BOOT_MARLIN_LOGO_SMALL.
• Lower flash usage on all boards since the smaller bootscreen is now enabled by default.

Configurations

Any of the default ET4/5 configs.

Related Issues

None.

@rhapsodyv asked me this on Discord, so I thought I'd explain it here too:

I had to move the URL text location up 20px on the 480x320 resolution because text overlapped the horizon line on the large Marlin bootscreen, so now it matches the 320x240 large bootscreen location.

To simplify things, the URL text Y location could be used for the smaller bootscreen(s). Otherwise, the URL text is displayed 1/2 way between the bottom of the small bootscreen & bottom of the screen:

I've tweaked the code to center the URL horizontally.

Using BOOT_MARLIN_LOGO_SMALL this way will break every build for TFT now on...

Old graphical lcd have different defaults from the Color UI.

For old graphical lcd we use big as default. So we have a option to use the small logo.

For color ui, we can't use big as default, as the big image only fits on big F4 boards. So, for Color UI, the default should be SMALL.

But how we will make different defaults using only one option?
Maybe adding a #if on the config?! I don't know if it will work well...

For that reason that @thisiskeithb added a new option just for Color UI.

I've already updated the configs repository so that BOOT_MARLIN_LOGO_SMALL is enabled by default (for all displays), so it will only affect cutting-edge users who try to use old configs, until they update them to the newest layout.

hmm side effect maybe, but i had to do that to use a normal one on 128x64 upscaled dogm

HAS_MARLINUI_U8GLIB is maybe not the right constant to check

There's TFT_SCALED_DOGLCD:

Marlin/Marlin/Configuration_adv.h

Lines 1596 to 1606 in a8c361c

	//
	// Classic UI Options
	//
	#if TFT_SCALED_DOGLCD
	//#define TFT_MARLINUI_COLOR 0xFFFF // White
	//#define TFT_MARLINBG_COLOR 0x0000 // Black
	//#define TFT_DISABLED_COLOR 0x0003 // Almost black
	//#define TFT_BTCANCEL_COLOR 0xF800 // Red
	//#define TFT_BTARROWS_COLOR 0xDEE6 // 11011 110111 00110 Yellow

	#endif

no, well TFT_CLASSIC_UI is same, but its the reverse, its not needed for this UI... big one is only a few bytes bigger

They're the same because of:

Marlin/Marlin/src/inc/Conditionals_LCD.h

Lines 325 to 328 in a8c361c

	// FSMC/SPI TFT Panels
	#if ENABLED(TFT_CLASSIC_UI)
	#define TFT_SCALED_DOGLCD 1
	#endif

I was surprised to see the small bootscreen made the standard for everything, but that wasn't part of my original commits 🙂

I was about to put in a PR to include TFT_SCALED_DOGLCD as part of the check.

yep avoid this "internal" one... may not be testable/set in the Configuration_adv.h ... i think this #if TFT_SCALED_DOGLCD in config should be replaced by #if TFT_CLASSIC_UI .. but its not our problem there :p

I just tested it and TFT_SCALED_DOGLCD works. I'll put in a PR shortly.

yep seems to works ive custom colors but... rmm well, do as you want :p

Might as well keep with TFT_SCALED_DOGLCD since it's already used in the config 🙂

See #20583 for the fix.
