I have created a simple TouchGFX GUI on my STM32F746G-Disco Board. Everything works well. In my project I need a DAC . So I switched on DAC1 in CubeMX. But when I do so and flashing the code to the Board the screen do not show the genereated UI anymore. Even when I switch off the DAC, the screen remains blank. What is the Problem there and how can I solve it?

The aim of DISCOVERY is to show the performance of the respective STM32, which usually involves connecting a large number of pins of the STM32 to external sensors etc. Therefore, you have to carefully check whether the respective periphery can still be connected to a pin.
In the case of the STM32F746G-DISCO, the DAC can no longer be used freely because the DAC pins are already occupied and cannot be routed to other pins.

You create project in TGFX ? Then reconfig in CubeMX isnt simple job.

Hello,
I am using :
My first project without ADC was working well. I was able to display animation on the HMI. But since I added the ADC, the screen is blank. After debug, I can see the tasks are running well, even the TouchGFX task also is running. But the display is blank.
I checked the pins and the pin PA0_C of my ADC is not in conflict. So I guess that the issue is coming from another side ?
