How to make a screenshot function with touchGFX ?

[nminh.1]

Hi all,

This is my configuration:

STM32F779NIHX motherboard with HDMI Interface, SD card

TOUCHGFX 4.16.1

STM32CubeIDE 1.6.0

RTOS V1

Everything works well, and now I want to make a screenshot (JPEG format) every 500ms or 1sec and save on the SD card. Someone already worked, can you share your source code?

thank you and best regards.

Hi,

Digging this up a bit. Were you able to develop what you wanted ? This could be of interest to other people if you succeeded.

I have never made one myself but I know that TouchGFX has the snapshot widget (look for SnapshotWidget.cpp/hpp in the framework folder) that takes a snapshot of the screen or area wanted into a bitmap.
