Flashing LED bug in Sunrise effect

Open AdmiralRaccoon opened this issue 10 months ago • 6 comments

What happened?

I have 2x60 WS2815 on each side of my bed, doing a sunrise effect the morning.

I´m noticing multiple annoying flashes during the effect (Duration 5 minutes), and it seems that only 1 LED is causing this (The 1st?), I have tried to capture it in this video:

Next step I would try is to make seperate controllers for each strip, however, this should work with 2 outputs on 1 controller anyway?

Thank you and have nice day Philipp

To Reproduce Bug

Just running the effect again

Expected Behavior

Making a smooth sunrise without flashes

Install Method

Binary from WLED.me

What version of WLED?

0.15.0

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

Anything else?

This LED Controller is a GLEDOPTO ESP32 https://www.gledopto.eu/Gledopto-WLED-LED-Controller-for-Digital-Light-Strips

I can´t tell if the bug exists in 0.14.4, as I directly flashed 0.15.0

Powersupply is 12V/5A, the Strips a powered directly from the controller, this is the LED Setup:

If anything else is needed, I´ll be happy to provide it.

regular ESP32 or one of the new ones?

just an ordinary ESP32 according to the specs:

may be related to I2S output, which is a known bug. Try this: add a third output with >300 LEDs (unused, this is to force RMT output instead of I2S) and see if it still happens.
