Problem went away on its own.

Hello, I just upgraded to a WLED solution after Arduino wasn't getting it done for me.

The problem is that when the screen should be black the LED's are on very dimly. I have scoured for a setting to change this but I am at a loss. Attached are 2 pictures, the first picture is WLED is being controlled by the RPi4/Hyperion, and the other the WLED is overriding the Hyperion. In both instances, the LEDs should be off but when Hyperion is controlling it the LEDs are subtly on. I am using WLED 0.12-B5 (yay for software configuration of GPIO headers).

The only hardware that changed was switching a RPI4 for a laptop.

I tried using HyperHDR with the same result.

Kind of like HyperHDR because it makes use of the multiple cores.

I don't know what the problem was, but it was related to the Arduino and RPi4. I ran HyperHDR on my laptop and used the capture device, worked perfectly.

My solution has been to upgrade from an Arduino solution to a WLED solution.

The connections are not soldered but they worked fine when using my PC to control it with Prismatik there were no problems. Any info on how I would solder it to the Uno?

The PSU powers the LEDs and Uno. The 5V and ground from the Uno are connected to the LEDs.

Hello,

I am running the setup in the title with 208 LED's. I get an inconsistent flicker/flash of another color. The following link gives a good idea of what it looks like. https://drive.google.com/file/d/12tFa8Z…iew?usp=sharing

The screen would be a solid green but get a flicker of red on all the LED's and go back to green. The video is a bit highspeed but provides a good example of what is happening with normal viewing.

I've changed the brightness settings on the interface and that helped but didn't alleviate the problem. Smoothing is enabled with a decay of 02, I made that change after the video was taken with no positive result. Black bar detection is enabled as well.

The adalight sketch I uploaded is the most recent version from the git (5 days ago?). The MAX_LED's are set to 208, LED_TYPE SK9822, 3/4 wire are commented/uncommented out as appropriate, color order is GBR, and serial rate is 115200.

Hyperion web configuration: Led Hardware is adalight, RBG light order, matching baud rate, and the output path is /dev/ttyACM0.

To troubleshoot I uploaded an adalight sketch to the Uno and controlled the LED's from Prismatik. This resulted in a perfectly working configuration (minus the lights my wife stepped on when I was testing it). Establishing the problem is something between the RPi and the Uno. I uploaded HyerBian to a spare SD card and got the same result, so I've reverted back to my config.

Any help is appreciated, I've been waiting to watch The Expanse S4 until this thing is up and running!

My Lightberry setup finally died and I've taken this as an opportunity to refresh my project. I'm upgrading to an RPi 4 and ezcap269, and rebuilding the LED portion as well. All the questions here are related to the setup and control of the LED's.

I've purchased a roll of SK9822 LED's, 4 pin wires, and connectors. I've broken the build into 2 components: control and power.

Taking on the control portion first. To control the lights from the RPi using a direct connection I'm under the impression that I would have to install pi-blaster. Then connect RPi's GPIO Pin 19 to the LED data and GPIO Pin 23 to the LED clock. What configuring is needed for pi-blaster and Hyperion to work together?

Power. I realized today that my old PSU is inadequate for the new LED's, I have just under 4 meters of LED's at 18W/m so I'm looking for a +75W PSU. As for connecting, my plan is to connect the PSU to the +5V and ground. The RPi to just the ground (GPIO).

Are there any egregious flaws in my setup or significant improvements that could be made?
