updateTime and updateDate touchGFX

ksale.1 · ‎2025-11-29

I am using STM32H750B-DK (DK32H750BSAT1). Following st tutorial in:

https://www.youtube.com/watch?v=dx7xHRH9YXg

The project built and ran successfuly on the board. Unfortunately upon implemeentig the updateDate on a textArea the update stopped completely for both time (was originaly uopdating before adding the text widget) and date. I have then deleted the textArea widget and commented out the relevant lines in the script, the update returned normally. I suspect the typogrphies is the root cause of the problem (I need advise on that. MyGFX is 4.26.0 , I couldn't get my way around Texts smoothly).

Simply in translation leave only <value> and click on wildcard1. In window initial value set for example 01.02.2025
size for buffer set to 15 ...

And what is question? FYI show zero code = solve zero problem.

Ohh boy seems copy video example , but ...

This example omit normal use and absurdly update time and date every screen frame (60xPS)
Read and use RTC this way isnot very effective. But this is next point to solve.

Now start with understand what you do. Uncomment all code except

	    Unicode::snprintf(textArea1Buffer, TEXTAREA1_SIZE, "%02d %02d %02d", date, month, year);
	    textArea1.invalidate(); // Force redraw

this can be uncommented only if textArea1 exist in screen with this name. Plus inside text must be wildcard.

As first step check name of your textarea (v26 can create different name as video tutorial in older v)
If is textArea1 then you can uncomment invalidate line . If have wildcard inside right size defined uncomment both.

Here is the texts and wildcard setting, which I am not comfortable with.

MM..1 · ‎2025-11-29

Simply in translation leave only <value> and click on wildcard1. In window initial value set for example 01.02.2025
size for buffer set to 15 ...
