Hello STMicroelectronics engineers and fellow users,
I recently purchased the STM32F746G-CU4 board and have been working on a project with it.
The STM32F746 is an excellent processor, and I was particularly interested in its ability to control a touch screen, which is why I bought this board. Yesterday, I finally managed to install the TouchGFX software and set up my development environment.
My plan today was to start by uploading a simple image to the display and then gradually research and practice the required features before integrating them into my equipment. TouchGFX has provided a very intuitive interface, and fortunately, I was able to upload an image to the board with just a few clicks. It is a very convenient environment for me.
However, I’ve encountered some problems.
When I downloaded the simplest images to the board (for example, just a plain white screen or a solid color), the screen displayed the color correctly. But when I uploaded the photo I wanted, the entire screen became corrupted.
I conducted several tests: adding text only, trying the provided clock image, using a 480x272 image, adding a diamond shape on a solid background, and so on.
Only two cases were successful: displaying a solid color, and displaying a diamond shape in the center. In all other cases, the screen became corrupted.
I’m not sure why this issue is happening, so I need help from the STMicroelectronics community.
Here is my development environment:
Board: STM32F746G-DISCO : DK32F746G-CU4
TouchGFX Designer: 4.25.0
STM32CubeIDE: Version 1.6.0 / 1.19.0
Windows 11 Pro
I look forward to your replies.
Thank you very much.
