Describe the bug

If I try to dim the display using HomeAssistant (e.g. to 50% brightness) then the display goes completely black. I have to set the brightness to over 85%, then the display will turn on again, but at 100%. If I choose a brightness below 85% then it becomes completely dark. The threshold value of 85% is not always consistent, sometimes it is 81 or 83. I also tried to lower the startup brightness in the config, I have the same problem there. I use the V07RC11 with the Sunton ESP-32-8048S070 (Touch)

To Reproduce

Set the backlight to lower then 80%

Expected behavior

The backlight dims to the set percentage

Screenshots or video

Display ist on with 100% brightness

Display ist off with 0% brightness

Hi, I've no problem with firmware 0.7.0-rc11 677e8cc and openHASP integration v0.7.2.

Hi,

I have the 0.7.2 installed (reinstalled it already)

How can I check if there is a hardware defect?

[WarC0zes]

You have the HA core up to date ? v2024.3.3 ?

[DukemFIVE]

Yes v2024.3.3

[marsman7]

which gpio pin is used to control the backlight on the sunton?

[smcgann99]

BACKLIGHT_FREQUENCY needs to be around 100 for that screen

[fvanroie]

Please test the latest Sunton builds from the Action tab.
