I am using the STM32F746-DISCO. Any ideas on how to shut down to a low power mode and wake up on LCD touch screen? Anything under 100mA current draw would be fine.

I already know how to turn off the LCD backlight.

    Hi MrChips,

    Yes you can enter low power mode and wakeup using the touch screen by configuring the EXTI on touch screen interrupt pin PI13 on STM32F746. There is an example which contains this feture on the application note of ''Low-power consumption on STM32F7''

    . You find the associated firmware on this package
