Hi guys, I'm trying to config my old system with a new led strip.
Before of it I driven 88 APA102 30/mt led like a charm without issues.
Now I changed my tv and I also upgraded led strips with 200 APA102 60/mt but with no luck.
What I have done, was just change the number of led in the Arduino sketch and in the Hyperion web ui. but I just have the first led powered on.
Following debug log and my Arduino sketch. how to solve?
thx a lot
Apa102 60/mt - 200 leds - Arduino Uno - rpi4 no light

did you try to set a color in the webUI or a effect?
-
The next step for me would be run a Test Sketch from fastled libary from arduino ide to Test if the arduino works correct with the LEDs
-
yes, just use on of them. change your led count and try it
-
i set it always to leds-1, so if the last one dont shine, i know everything works
-
No i mean Number of you leds -1 -> 200 -1 = 199, for example the ColorPalette Sketch with those settings
edit: sorry this example has no clock pin, but you apa102 needs one, so just use the Blink Example sketch with the right settings

I think ( my experience/opinion) that you should look for hardware problems.
not to dive to deep into sketches of Arduino's,
but go back to basic and first check if the ledstrip you bought itself wants to fire.
just take the Arduino out of the setup and connect the ledstrip directly to GPIO pins 10/11
and ledcontroller APA102 SPI start with 80 leds to test in led layout.
2 scenario's
- if they are not firing then and debug log doesn't say errors AND leddevice is running in Hyperion....
it has to be the new ledstrip guy.
- if they are firing without problems with that setup then something has to be not correct in the sketch of the Arduino or doesn't recognize the ledstrip.
goodluck.

Thx for the time you dedicated to me. I copied your new sketch but the result is always the same unfortunately: just few leds on at the beginning of the led strip in solid color.
I saw you modified bgr with rgb, I’ve done the same in the Hyperion webui but nothing… it seems there’s something in the arduino communication that doesn’t work, but what?
I found an error in the debug log about the led, maybe could help to know what to do....
Anyway now leds are not recognized in the component status
-
are you sure that the leds work fine? sounds like a faulty led
