Hi, i’m trying to compile a slightly modified version of the Noise.ino example in the FastLED library for the Photon board. I’ve the same code up and running on a Teensy 3.1 board, in the Particle Web IDE compilation fails on this line: FastLED.addLeds<WS2812B,23,RGB>(leds,NUM_LEDS); When removin…

Could you post the error message (and the next few too)?

Hi ScruffR, thank you for your quick response, here are the error messages: In file included from lacktable.cpp:2:0: FastLED/FastLED.h:12:2: warning: #warning FastLED version 3001000 (Not really a warning, just telling you here.) [-Wcpp] #warning FastLED version 3001000 (Not really a warning, ju…

OK, it is a bit odd and I’m not sure why, but as it seems the default zero for the third parameter is not allowed in this constellation of templates. I know it works fine for “normal” functions, but my C++ is a bit rusty when it comes to templates. As a workaround just add the third parameter (0) …

Hi ScruffR, i’ve pasted the complete code here: http://pastebin.com/vARrsH66 i tried adding a zero to the parameters in line 45 with no luck… kind regards, Christoph

This line does look wrong FastLED.addLeds<WS2812B,23,RGB>(leds,NUM_LEDS,0); As the error notes state the template should be FastLED.addLeds<WS2812B, DATA_PIN, CLOCK_PIN, RGB>(leds,NUM_LEDS); // or with ,0 // or FastLED.addLeds<WS2812B, DATA_PIN, CLOCK_PIN>(leds,NUM_LEDS); // or with ,0 // or jus…

NUM_LEDS is #defined in line 9 as product of kMatrixWidth * kMatrixHeight - where did you see it commented out? Even when i change the data pin to 1 an try the three variants you proposed, i get the same error… i tried the following function calls: FastLED.addLeds<WS2812B, 1,0, RGB>(leds,NUM_LEDS);…

I see, I had mistaken the green line for a comment and didn’t look close enough :blush: I’m so used to the Visual Studio color scheme. Since I can’t see the templates the way you posted the code lines above, it’s a bit hard to tell what you did :wink: All three lines look exactly the same - after…

OK, forget what I said above :blush: I had some tests with your code and the original XYMATRIX sample and I figured that your issue seems to come from your RGB template parameter. If you substitute it with BGR the code builds. But why the templates without color encoding scheme fail is still not …

Thank you very much for your support! The last hint did the trick. You may see the result of your support here: This is an Ikea Lack table with integrated a 12x23 WS2812B matrix which now displays the noise example of FastLED. The first version of this table was powered by a Teensy 3.1 without Wif…

Looks cool :sunglasses: Freut mich, dass ich helfen konnte! Jederzeit gerne wieder :+1:

Hmm, yes? The point being?
