TSL2591 brightness sensor : dark/light theme ok, screen brightness not changing

[aegidius77]

Hi,

What hardware do you have?

• 7 inches IPS DSI screen with brightness hardware button adjustment (https://store.freenove.com/products/fnk0078?variant=43034491027654)
• Pi 3 model B v1.2
• TSL2591 brightness sensor (with correct wiring, seller's one is not correct)

What crankshaft version?

20250111 Pre-release ( Version : 124fdc2 ; Build Date : 2025-01-11)

Steps to reproduce the bug, if you're planning to report a bug. Please indicate whether the bug is always reproducible.

Hardware manual brightness adjustment woks fine.
Software manual brightness adjustment woks fine (when no sensor is plugged of course) .
Both adjustments seem to be independents from each other.

Lux values seem to be correctly read, but only dark/light theme is changed, screen brightness remains unchanged.

always reproducible

Hi,
Same problems using official 7" screen.

There is a similar issue #515. PR #619 should have fixed it. Could you do some debugging based on that PR?

[aegidius77]

Thx.

I modified this service_lightsensor.py file from the SD card, but it broke my crankshaft (blank screen at boot)
Not sure I made it the right way.

Can't do other tests at the moment as install doesn't work anymore (see #700 )
