Hi @tonhuisman see #4920

Just tested https://github.com/letscontrolit/ESPEasy/actions/runs/7338328820 using "ESP_Easy_mega_20231227_display_ESP32_4M316k.bin" and it works for the issue #4920.

To be more detailed, it needs about 5 seconds to "clean up" the Line 1 (first line) both at board boot and when some text is inserted and later removed.
So when the Line 1 (first line) is blank (not valued) anyway the "ESP Easy" message is displayed and it disappear after about 5 seconds.

Well, the main intent of this PR is to add support for ST7032-based displays, but that doesn't yet work as intended.
I just added the extra feature of clearing the splash after 5 seconds as this plugin was already in this PR, to try and avoid somewhat complicated merge actions later...
Maybe I'd better separate that second part into a new PR 🤔

Ok Ton, thanks.
I noticed another thing, the LCD2004 currently does not supports accented letters, like "è" "à" "È" and so on.
Is it possible to implement that?
I don't know if this and this can help.

There is support for some special characters already, and also a define to enable a few Polish characters in a Custom build.
It may depend on the character rom included in your display wether some other characters are already supported, not sure, (only own one of these displays...), but you could try from rules to send some special characters and see what the results are.

@iz8mbw I've migrated the 'splash-clear after 5 sec.' feature to #5043 to give it a shorter ETA of being merged 😉
Not sure if this PR will ever be possible to complete, as support/documentation for the ST7032 is really poor.

@tonhuisman I have tested by build the latest commit (fb95d8c) and the issue persist.

@tonhuisman sorry my fault, since it was not (yet) merged into master the fix was not included.
Then I have tested "ESP_Easy_mega_20240429_normal_ESP32_4M316k_LittleFS.bin" and I can confirm it works!

Thanks.
