Odroid C4 ws281x support

I have an Odroid C4 that I am trying to get working with a 5V 4m LED strip. I installed Hyperion under Odroid's default Ubuntu Mate OS. I ran sudo updateHyperionUser -u root to use ws281x. I am not sure which pin to use, right now I'm plugged into pin 12 (labelled 12 PWM_E GPIOX.16 (#492) I(P/U)) and have 14 plugged into the ground on the 5V supply.

I'm not sure if that's correct, currently the first LED is green and that's it. In the logs this message repeats endlessly:

2023-04-03T01:42:37.890Z [LEDDEVICE|First LED Hardware instance] (ERROR) Device disabled, device 'ws281x' signals error: 'Failed to open. Error message: Hardware revision is not supported'

Lord-Grey ok, thanks for the tips! I'll submit a github issue for Odroid C4 support.

In the meantime, I have a spare arduino uno, a few WeMos ESP8266 D1s, and a couple different FTDI adapters and maybe I can get one of them to work for me.

pclin I have a WeMos Lolin32 Lite, would that work?

WEMOS LOLIN32 Lite — PlatformIO latest documentation

I couldn't find anything about ESP32's in the documentation here, maybe I am looking in the wrong place:

Overview | Hyperion

Update! I made a little board that uses a level shifter and ESP32.

Even though I'm just using 1 channel right now, I added in support for four since the level-shifter supports four, added the optional resistors in their own channels, and then added a couple of buttons because there was room on the board.

I have WLED 0.13.3. It functions ok, but there is about half a second of lag between what I see on my screen and the background lights. Is there a way to make there be less of a delay or make the transitions smoother?
