M5 Stack Core2 Touchscreen unexpected Values

[haipas]

Hello,

I have the problem, that when I enable the touchscreen in the Core2 I get unexpected values.
I get the following log output.

2023-09-16 12:00:26 V (02:06:54.027) FT6X36: X=512 Y=128

I expected values between for x between 0 and 320 and for y 0 and 280. The values are also not really related to the position on the screen, it looks to me that the values are random.
To be sure that this issue is not hardware related, I tested everything on two different hardware modules.
The Original M5 Stack Software Displays correct data on the screen. I also tried an Arduino example from the library m5gfx this shows also the correct touch values.

Best regards
