Sensor Display Stopped Working - EspHome and ili9xxx

carltonb · August 14, 2023, 2:17pm

I went on vacation for a few weeks. I came back and upgraded to 2023.8.2
I also upgraded my EspHome since it needed upgrading as well.
I then restarted everything.
All of 8 of my sensors units that have screens attached to them, the screens stopped working.
I am still getting data from the sensors. I have been running these sensors and screen for almost 2 years with no problems.
There are no errors identified in the EspHome file. See code below. But I am getting the following error in the logs.
I have searched to see what changes may have been made in EspHome but it does not look like any thing that will affect what I have.

[07:06:14][W][component:204]: Component interval took a long time for an operation (0.14 s).
[07:06:14][W][component:205]: Components should block for at most 20-30ms.

display:
  - platform: ili9xxx
    model: TFT 2.4 #320x240
    cs_pin: GPIO22
    dc_pin: GPIO27
#    led_pin: GPIO32  ### see note below ###
    reset_pin: GPIO14
    update_interval: 30s
    rotation: 270
    id: my_display

Any ideas of why they all stopped displaying data.
Thanks

my displays just started displaying this error upon upgrade to 2023.11.6

update- just change the logging level to ERROR.

I’m still not getting any temperature data from home assistant on the display.

The display I’m using is a ESP32-2432S028 which has a ESP32-WROOM-32 module with a claimed 520kB of SRAM, 4MB FLASH and a 2.8" 16 bit RGB display at 240x320 resolution driven by an ILI9341 chip.

This worked ok with the verison of the ILI9341 display platform that I last used (March 2023) but with the ILI9xxx version when I tryto add code to use the display I’ve has to add the dimensions parameters and cange rotation values in yaml. The big problem however is that when I try to write to the display, locally source information (e.g. wifi signal strength) display ok but I cna’t get updates from remote sensors.

Looking at the log I notice:

RAM This lists as 327680 bytes (320kB) but the data sheet for the part lists 520kB… but it is Chinese so that could just be a specification error. Even with the smaller RAM size, only 12% is reported as being used.
When it runs, it reports “Could not allocate buffer for display!” - why not!
It them reports "Component display took a long time for an operation (0.06 s)". I tried different SPI clock rates and got similar results - 0.06 seconds at 80MHz and 0.07 seconds at 40MHz. On a more complex YAML version where I was updating the display these times were unchanged.
There is also an error that I don’t understand “Socket operation failed: HANDSHAKESTATE_READ_FAILED errno=11”

So, any suggestions would be appreciated.

fwiw in notifications I had to re-add it to esphome and all is well

Same for me

Deleted the component from ESPHome and reinstalled it… and it is now reading the sensors again. The “Socket operation failed” message has gone too.

The display works ok with a 80MHz SPI clcok but I’m left witht the display buffer failing to allocate and the display class (when I use a lambda) has changed to “Display” from “DisplayBuffer”.

I found this thread because your code contains:

  - id: my_black
    hex: 000000

Interestingly, that crashes my validation. There’s no problem if I enter hex: a00000 or anything else that doesn’t start with a number. Also fine if I use hex: "000000"
