Flickering/flashing 12V strip with Ericsity controller

Issues
1

Hi all

Short disclaimer: I know very little about what I’m doing :wink: I tried to do my research but I realize that I am hitting walls left and right. It would be absolutely amazing if you could help me out!

Issue:
LED strip keeps flickering/flashing. Please see details of my setup below, here some of my troubleshooting steps.

Initially completely normal setup with strip plugged into V/GPIO16/G. Upon initial setup there was terrible flickering, even when limiting to 850A. Flickering was constant at high and medium brightness, at 13/255 brightness it still flashed every couple of seconds. Issue for both solid colors or effects

I then disabled the first LED and reduced the number of LEDs by one, which made the situation significantly better, especially for solid colors on high brightness. But there was still a lot of flickering/flashing every couple of seconds.

I then plugged the spare power and ground cables into the remaining V and G. No real change.

I then switched the data cable and WLED setting from GPIO 16 to GPIO 02. spare V and G are still plugged in as before. This has significantly improved the situation, even on full brightness white.

I then activated the first LED again and set the length back to 60 LEDs. Now some flickering is back. Around 233 bright warm white there is a pretty much constant flicker, at full brightness about once every 10 seconds.

What could be the issue here?

Wiring setup:

Data plugged into GPIO 02, power and ground plugged into neighbouring V and G.
Spare power and ground (I’m assuming these are for injection) are plugged into spare V and G.

There is currently no additional cables in use. Power brick to controller, controller directly into the LED strip with included cables. Controller to strip there is about 20cm of cables.

WLED Setup:

Power Situation:
LED strip:

  • 3m strip with 21W/m = 63W
  • 12V
  • 5.25A

Power Brick:

  • 12 V
  • 5A

WLED:

  • set to 4’800mA

Anybody have any inputs?

as it apears every 10 sec its the PSU that gets the overload limit

did you check that at saying 25% brightness 40 in the top Right bar
and change the LED conuming mA to less then 35mA per LED

I just tried setting the mA consumption to both 35mA and to less than 35mA per LED while using GPIO 16 (the one that caused more problems) while using the entire 60 LED segments and setting the brightness to 40. The flickering /flashing continues - see attached. PXL_20240509_064848237.LS-ezgif.com-video-to-gif-converter (2)

For the time being I switched back to the setup with GPIO 2, 12V per LED and skipping the first LED segment, which seems to work fine.

But this seems wrong, not being able to use GPIO 16 and having to skip the first LED.

Hi this is real MAD

what if yoiu invest 5USD and switch to a Simple D1 Wemos ESP8266 Controller
avauilable everywhere in the NET
this may realy be a controller issue as it uses ““internal Timing Interupt”” conection .

I was hoping to use a more integrated controller with a pretty box around it and everything to make it look like less of a DIY project. Do you maybe know of a different controller that works more stable?

Had to put this project down for a while but am back at it again, still with the same issues of course.

I decided to switch out the controller due to the inputs about the logic level shifter. It works great with the cod.m controller :slight_smile:

Did you try using QCCAN TTL TO RS485s? They work great and cheap as well
