any known good yaml configs for esphome for the tab5 v2

manmade

I'm looking for a working yaml to set up the tab5v2 for use with home assistant. So far it's taken me 5 hours to learn that I have a v2 tab5 and not the one that the demo uses. I have gotten it to boot, and it connects to the wifi, but I just get a blank screen with blacklight on. no telling if touch works or anything else.

@manmade nothing is shown on the screen still, however I have been able to add the device to home assistant and connect to the api to turn the backlight on and off.

I dont see the nRESET signal being removed from the LCD, TouchPanel (and Camera).
It's a low=active reset for these devices, and the E1 pi4ioe5v6408 chip that controls them will default these pins to low (actually, input-pulldown) and holds the reset pin active. These are pins 4,5,6 on the chip:

Maybe you need something like:

  - platform: gpio
    id: lcd_nreset
    name: "LCD nRESET"
    pin:
      pi4ioe5v6408: pi4ioe1
      number: 4
    restore_mode: ALWAYS_ON

  - platform: gpio
    id: tp_nreset
    name: "TP nRESET"
    pin:
      pi4ioe5v6408: pi4ioe1
      number: 5
    restore_mode: ALWAYS_ON

  - platform: gpio
    id: cam_nreset
    name: "CAM nRESET"
    pin:
      pi4ioe5v6408: pi4ioe1
      number: 6
    restore_mode: ALWAYS_ON

Because these are active-low lines they are being applied when the unit powers up, you have to explicitly remove them after boot.

This is a guess, I'm not running HA on my tab5. There may be other things that need to happen too or are broken. But I just spent all day playing with some TAB5 hardware stuff in MicroPython and
this was one of the things I discovered..
