LEDs don't light up

Hello,

After trying several options I always get the same result, Hyperion looks like it starts correctly, the grabber is working fine apparently, but the LEDs don't light up, only the initial flash in the setup works. Then, the TX blinks but nothing lights up.

This is my setup:

• Raspberry Pi 3B+
• OSMC
• Arduino MEGA
• WS2812B

This is the sketch I'm using, although I tried like 2 or 3 more:

This is the Hyperion.config:

And this is the log:

I checked that the LEDs work, with DI pin connected to D6 and GND to the Arduino. I tried also with Raspbian but same result.

I don't know what else I can try. Any idea of what's going on?

Thanks,

That has been clipped, correct?

Yes, it has.

Not sure.
Try lowering:

Code

#define serialRate 500000

And.

Code

"rate"     : 500000,

Hope it helps.

I tried different speeds but still nothing. I'll try to investigate a little more tomorrow.

I've connected an LED to the Arduino to sort of debug it. I could only see that this piece of code is reached:

if (transmissionSuccess)
{  
  digitalWrite(LED_BUILTIN, HIGH);
  endTime = millis() + OFF_TIMEOUT;
  FastLED.show();
}

So I tried to hardcore the LEDs color, instead of this code:

leds[idx].r = r;
leds[idx].g = g;
leds[idx].b = b;

This line:

leds[idx] = CRGB(255,0,0);

But nothing, I'll continue fiddling with the code, maybe there's some misconfiguration using the library with these leds.

PS: @TPmodding Yes, I checked that and it's correct.

Here's the differences of /dev folder when the Arduino is plugged in.

Taking a closer look at this page's tutorial, I saw that I have to set this:

#Increase UART speed
init_uart_clock=14745600

So I did, rebooted, and then the LEDs were on but completely random, and static. Then I restarted Hyperion and they were gone, rebooted the Raspberry and still nothing, the same behaviour as always. Initial flash works, but nothing else.
