Animation Performance Issue with NUCLEO-G071RB + X-NUCLEO-GFX01M2

[wow]

Hello,
I am currently using NUCLEO-G071RB with X-NUCLEO-GFX01M2, where I have implemented an animation that periodically updates a part of the display.

When setting the animation interval to 100ms, I noticed that the main loop’s while execution time exceeds 100ms, causing delays in execution. To achieve smoother animation, I want to shorten the animation interval.

1. How can I reduce the delay in the main loop execution?

2. Could the delay be due to the low clock speed of the MCU or the fact that the display uses SPI communication?

3. If I switch to an MCU with a higher clock speed and use a MIPI DSI or RGB interface, how can I migrate my existing SPI display-based project to the new hardware?

Any insights or guidance would be greatly appreciated.

Thank you!

Hello @wow ,

How do you set your animation interval?
It seems that the animation repeats permanently, we do not have this feature by default, you will need too add some interactions or use another way to program that.

How do you

When setting the animation interval to 100ms

What is preventing you to set the animation to something else than 100 like you seem to be doing above?

Can you share your project?

For that you would have to create a TBS for the new hardware or use a hardware combination that already have a TS (like the STM32G071RB + GFX01M2 that you are currently using) and then you can go to Edit => Import => GUI and select your .touchgfx project to copy your GUI to your new project.

Hello @GaetanGodart ,

Thank you for your response.

Unfortunately, I cannot upload the source code as it is the property of our client. However, I can provide some details about the implementation.

The animation is implemented using a custom container with animated images. On the screen, approximately 30 images (15x15 pixels each) are animating. The animation is set to loop with an update interval of 100ms.

The reason for setting the interval to 100ms is to achieve a visually smooth effect.

If you need any additional details to help diagnose the issue, please let me know.

Thanks again for your support.

Go back to basics. Little teory, displys have own refresh rate 1 = animation cant go smoother as this.

GUI based on update display method have other refresh rate bigger or same as 1.

Normal refresh rates is based on human eye ... more as 25Hz ( less as 40ms ), but good GUI use more as 47Hz ...

Standart TGFX setups use 60Hz (16,6ms) , but you can choice any value 40-100Hz is ok. After you choice then animation is based on this or 1/2 1/3 no under 25Hz. 

Now we can calculate data required send to disply for this and ack if is capable.

And last step is your OS or no OS based sw. If your are in no OS while = your job is manage no blocking code.

Have you meet all this criteria? Is your update method partial or full screen?
