Support for m5dial touch driver

[dgaust]

Describe the problem you have/What new integration you would like The m5dial uses a GC9A01 screen with a FT3267 touch driver. I have been able to integrate the display using an external component, but not the touchscreen.

Please describe your use case for this integration and alternatives you've tried: I have tried external components with used for other devices with GC9A01 based screens (like the ones with CST816S series touchscreens), but have not had any luck registering touch events.

Additional context Details of the m5dial are here, including pinouts and other details

I think? this might be the relevant driver file for the touchscreen

I'd like to do exactly the same. Maybe this Arduino lib could help: LILYGO-TRGB-Library

I found an ESPHome config file for M5Dial 1.28" Round Touch Screen.

And it works !

Yeah, that's mine, I ended up writing a custom component that got the touchscreen working based off a similar touchscreen component

You should have put a comment here to share 😉 Maybe you can create a PR to integrate it in ESPHome.

Probably, if someone with more experience than me with esphome components wants to the repository is here.... It works, but no idea how it complies with esphome's requirements

More discussion on how it all comes together is over

Coming back to this, you can use an inbuilt touch component for the touchscreen in the dial. Just need to define the address for it to work.

touchscreen:
  platform: ft5x06
  address: 0x38
