GT911 driver : need a sleep() method to totally powered off the touch screen (like the GT911 driver used in Aruino IDE : TouchDrvGT911.hpp)

Additional context

Hi !

I'm using the Lilygo EPD47 with the touchscreen.
In deep sleep, i've a 5.7mA power consumption : too high.

If i used the demo code and compile with Arduino IDE, the power in deep sleep is 380uA ... much better.

If i move all the C code (founded in demo code) used for the deepsleep in a Lambda, i'm stuck with the line making the touch screen sleeping : touch.sleep();
There's no sleep() method implemented in GT911 driver for ESPHOME

So, i think that in ESPHOME, the deep sleep of this board is not total for the touch screen.

In GT911 for Arduino it's :

 void sleep()
    {
        writeRegister(GT911_COMMAND, 0x05);
    }

Is it possible to add this to the GT911 driver ?

Thanks.

Hi!

I've submitted a pull request to add this functionality directly into the ESPHome gt911 driver: esphome/esphome#9994

The GT911 will now automatically enter sleep mode during on_powerdown.

To help get this merged, it's best to test the changes locally, as per the instructions from the ESPHome bot here: esphome/esphome#9994 (comment)

Feel free to give it a try and leave feedback on the PR if it solves your issue!

Thanks 🙂
