Trouble Displaying ADC Values (???) in TouchGFX Application

[Ayoub_Bnina]

Hello ST Community,

I'm currently working on a project involving an STM32H7B3I-DK microcontroller, ADC readings, and the TouchGFX graphical framework. I have successfully implemented ADC reading and data transfer through a queue, but I'm encountering challenges with correctly displaying the ADC values on the TouchGFX screen. I have attached a screenshot for reference.

Issue Details:
- Using TouchGFX for GUI development.
- ADC values are confirmed through the data queue.

- The displayed values on the TouchGFX screen appear to be erratic and not reflecting the expected values. (Text area buffer size is 5)

The graph is just static not real values yet

I would appreciate any insights or guidance on properly interpreting and displaying ADC values in a TouchGFX application. If you've encountered similar issues, your assistance would be highly valuable.

I found out that I haven't specified the wildcard range, that caused the problem.
