Old question, but still unanswered.
Can anyone provide a working example of holding a digital pin high during light/deep sleep?

Re: TFT Display on during ESP32 deep sleep?
Hey boarchuz, thanks a lot for the tip! At a first glance that might actually work!
BTW, do you mean rtc_gpio_set_level(pin, 1)?
Also, could you point me to the schematic you pulled up?

TFT Display on during ESP32 deep sleep?
I am using M5Stack where a TFT display is connected to ESP32 via SPI interface. Currently, going into deep sleep (esp_deep_sleep_start()) or even light sleep (esp_light_sleep_start()) powers off the display. I was wondering how we can get the ESP to go in deep sleep without powering off the LCD. Say...
