STM32H7BWorkshop2020, I upgrade IDE, TouchGFX, Firmware repository to 1.08 and all. Started from fresh sample from the workshop, TouchGFX generates codes that cannot be compiled. What should I change?

[FMarr.1]

the error seems to be in Texts.cpp

By the way, i started from scratch another project, following the indication in the workshop.

It works except the touchscreen does not work. I compare with the workshop code and

missed code in TouchGFXGPIO, this is code generated from TouchGFX. So maybe there miss some

setup i should do to tell TouchGFX i am using touch screen.

Hi FMarr.1,

The compiling error you faced seems to be linked to the fatc that you upgraded to the newest version. I believe some functions are no longer supported in the newest version. So following the indication of the workshop but doing your project yourself is the correct way to go I think.

If you touchscreen does not work, it could be that you haven't initialized the touchscreen correctly (I2C not enabled, etc.). Since you are working with H7B3-DISCO, I recommend you to use the Application Template available in the Designer or at least to refer to it.

Thanks for reply, i will compare the two versions and try to see where I am wrong.
