Can you put the STM32F746G-DISCO into a 'sleep mode" and wake up on screen touch.

[LBend.1]

I'm trying to implement a screen saver/sleep mode onto an application so if the screen hasn't been touched for a period of time the device will enter a sleep mode (turn screen off, save power, retain state of the model). Then only when the screen is pressed should it wake up and return to normal operation.

Is this possible? I cannot find anything describing how to do this.

Thanks!

Hi,

I would suggest to edit the Topic section of your post to add more tags related to the board to increase the visibility of your question.

Concerning TouchGFX there are no "complex" steps with this since TouchGFX is driven by external signals like interrupts from the display or from a display controller. If you wish to save data you can have a look at the Backend Communication article which will help you understand how to communicate between your UI and the rest of your system. What you have to do is just to stop those signals so that TouchGFX will not render anything.
