TDA4VM: human-computer interaction

liuyang liuyang

Part Number: TDA4VM

We want to implement a GUI display APP with buttons on tda4vm j721e platform, which can respond to touch clicks and sliding processing.
In the reference demo of the SDK, only examples of UI display using draw2d are found, but no examples supporting human-computer interaction and window management are found,
If I want to realize the graphical APP with button and support sliding, how should I develop it? Can you provide a reference demo?

Thanks.

Hi,

Qt can be an option to realize what you need.

TI SDK provide the ability to integrate Qt applications, we did have some out of the box demos in the past that allowed touchscreen (or mouse) and sliding processing etc. You can use the reference linked here to integrate further: https://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Examples_and_Demos_Matrix_User_Guide.html

We don't have a plan to support a reference demo on TDA4VM with this same appilcation. It should be possible to port this quickly and use it as a starting point. In addition, Qt itself has plenty of examples that can be great starting points.

Regards

Karthik

Hi,

Thank you for your suggestion.

If I use QT, there are two questions we want your support:
1. How to pass touch event to QT? Our touch panel is connected to r5f.
2. How to pass QT GUI to the display screen? Do I need to connect QT with tiovx?
We connect a display screen through DSI, which is also connected to r5f.

Sincerely
