ili9341 triggers watchdog if nothing draws in the lambda

[Aculeasis]

The problem

I found that if nothing draws in the lambda or the lambda isn't declared, the watchdog timer will be triggered. I draw a dot to fix it. Is this a bug, isn't?

This will be fixed in as soon my PR is merge into the dev branch. Or you can test out my reworked version on https://github.com/nielsnl68/switchplate by including:

external_components:
    - source: github://nielsnl68/switchplate
      components: [ili9xxx]
      refresh: 10m

spi:
  mosi_pin: 23
  miso_pin: 19
  clk_pin: 18

display:
  - id: my_display
    platform: ili9xxx
    model: ili9341
    cs_pin: 5
    dc_pin: 16
    ...

@nielsnl68 Is this fixing this as well? https://github.com/esphome/issues/issues/3317

[nielsnl68]

Yes, that is being fixed with my PR.

[autox86]

Lovely. Thanks a lot!!

[nielsnl68]

BTW i have also an enhanced version for the ili9xxx family drivers which can be found part of my switchplate project at: https://github.com/nielsnl68/switchplate

you can easily load it as external_components:

external_components:
    - source: githup://nielsnl68/switchplate
      components: [ili9xxx, ili9341]
      refresh: 10s

When you have time could you test it as well? Maybe you have other displays in the same family as well to test. I love to hear of ALL works well. But be aware it is still in development i could change thinks when needed.

Currently the driver component supports the ILI9341, ILI9342, ILI9481, ILI9486 and the ILI9488.

@nielsnl68 - Do you have any knowledge of when your fix will be merged in to the DEV branch? I am having the following issue #3317 and hoping for your fix, but spotted there may be additional errors? (https://github.com/esphome/esphome/pull/3795#issuecomment-1270262065)

Apologies, not super up on github and how these projects work (basically how and when a merge to DEV may happen), thanks for the hard work on this!

[nielsnl68]

When you use the ili9341 then there is no easy, only when you want to use a bigger screen, then the memory issue will pop up. I do not know when or if @jesserockz will add my PR to dev. Better to ask @jesserockz on Discord.
