EspHome & TTGO T-Display: no screen refresh

leonb · July 8, 2020, 7:35am

Thank-you that has fixed it

I did look at the two st7789v.cpp files and did no see a deference (must have missed something) and just assumed that the musk95 files were updated (silly me for assuming).
I copied from semenyak’s and its all working

Thank-you again for your support

Could you pls post the “display” section of your code?

This seems to be at the heart of the matter.
Have you done Clean Build Files?

vix66 · November 28, 2020, 7:39pm

Yes, but nothing !!

I try to compile this project : https://github.com/anton-semeniak/Esphome-TTGO-T-Display-Weather

The first error is in custom_components renamed to components
The second is Unknown value ‘RGB565’, valid options are ‘BINARY’, ‘GRAYSCALE’, ‘RGB24’: renamed to RGB24
the third is in the bl_pin: renamed to bachlight_pin

nickrout · November 28, 2020, 7:45pm

Do you have the custom components directory?

vix66 · November 28, 2020, 7:50pm

Cattura

if I rename it to “components” it goes on

vix66 · November 28, 2020, 7:54pm

Cattura

This is the directory

nickrout · November 28, 2020, 8:02pm

Surely this issue should be raised on anton’s github

vix66 · November 29, 2020, 6:23pm

i found the solution:

replace in display.py.

spi.SPI_DEVICE_SCHEMA

with

spi.spi_device_schema()

nickrout · November 29, 2020, 6:24pm

Good, have you submitted a PR?

Olivier974 · December 16, 2020, 6:00pm

Hello @semenyak,

i have a 240x320 st7789v screen, what can i do to make it work with your custom component please?

the screen works but display only the 135x240 pixels like a TTgo screen…

Thanks

nickrout · December 16, 2020, 8:24pm

@semenyak will know better, but take a look at these two files

Olivier974 · December 17, 2020, 11:25am

thanks @nickrout but i already look but dont understand how and what modify to specify the 240x320 pixels…

nickrout · December 17, 2020, 6:45pm

In the second file the width and height have been changed from 240 to 135 and from 320 to 240. See lines 265 and 269. Revert them to 240 and 320.

Olivier974 · December 17, 2020, 7:16pm

thanks for your help! didnt see that…i ll give it a try!

one thing i dont understand is i copy all the 3 folder to custom_components in HA but now when i compile in Esphome i have an error with st7789v that is not found.

I have the basic AddOn of Esphome and st7789v is already include, but i am under HassOs and i cant modify anything from the st7789v driver in Esphome…

i can modify in custom_component but it seems to make a big mess with the st7789v driver already include in Esphome.

Sorry…my knowledge is a little bit limited…dont know if i am clear or not …and if you understand?

nickrout · December 17, 2020, 10:13pm

It is not a HA custom component, it is a ESPHome custom component.

Create a directory named custom_components inside the directory that holds your esphome yaml files. Then put the 3 directories and their contents inside that directory.

Olivier974 · December 18, 2020, 2:25am

yes, sorry, not well explained…

i do like this but cant compile anymore after that

nickrout · December 18, 2020, 3:57am

Post an issue on @semenyak’s github repo.
