There is delay in screen interaction and touch buttons.

[Freedom_Neo]

MCU: STM32H7B3IIT6 Custom Board

GUI: TouchGFX Version: 4.18.1

IDE: STM32CubeIDE Version: 1.8.0

CPU Clock: 280MHz

Peripherals & Timers Clock: 140MHz

I created a new project, but there is a delay in screen interactions. I summarized the situation in the video below. Anyone have an idea about this? Why could it be.

Hi Freedom_Neo,

Could you give more information about your configuration please ?

• Which board do you use ?
• Which version of TouchGFX Designer do you use ?
• Which version of STM32CubeMX do you use ?
• Which compiler do you use ? (EWARM, STM32CubeIDE, MDK-ARM ...)

I'm suspecting something like HAL_Delay() functions which might be called in your code. Is there anything like this ?

You can also verify if your clock frequency is "normal" that is to say, if 1 sec in real is 1 sec for your board. For this, I can suggest you to try to add an image that moves from a point A to a point B in 1 second for example with a "MoveAnimator" mixin (https://support.touchgfx.com/4.18/docs/development/ui-development/touchgfx-engine-features/mixins), and see if the animation is done in 1 sec, or more.

Thanks,

/Osman

No, I dont use HAL_Delay() functions.

Dont have time problem, I see 1 second

Hi Freedom_Neo,

Have you tried debugging this with break points ? Do you store your resources in an external RAM ? if it's the case, the connection between your board and your RAM might be insufficient.
