Has anyone had any experience with using an Arduino Yun with a strip of TM1804 LED’s? They’re working fine from a Teensy 3.1, but the same code on a Yun is converting black to a half’ish brightness red, and all colours have a red tinge. I’m using the FastLED 2.1 library.
Electronics isn’t my strongest skill set(!) so if I need to alter the data line output, please can I get some pointers on what might be useful to try?

There’s no support for the Yun yet, which means that it is likely that pin definitions are falling back to digitalRead/Write, and/or something is off with the clock timing on there. I haven’t yet gotten a Yun to work on porting to, haven’t even had a chance to look at the specs yet.

I’m using a Yùn fine on one project (it’s just a Leonardo) though not with 2.1 yet, I don’t think?

Thanks for the responses:
@Daniel- I thought it might be a timing issue, but was reluctant to start poking around in the assembler code to change timings without checking if I was doing something fundamentally wrong, like using an unsupported board! Is Yun support planned - I realise it’s not a priority, but is it on the radar in terms of a time-scale?
@Robert- I was getting no output using an earlier version of the library (v2 final) - can you tell me what LED chipset and library combination you were using please?
I’m hoping to use the Yun because the built-in WiFi is a better alternative for my project than a WiFi shield for the Teensy.

The LEDs were WS2812Bs, and I’m pretty sure I started developing this project on 2.0, and I think I upgraded to 2.1 without any issues at all. The Arduino part of the Yun is “just a Leonardo” so I don’t think there ought to be any code changes in the library to support it.

I’d double and triple check your wiring if you’re having odd issues when you move from one controller board to another.

(And yeah, the wireless sketch upload on the Yun is worth the price of admission alone. Very handy!)

Huh - I wonder if there’s an extra define check im missing for the Yun’s MCU?

My experience was, you tell the Arduino IDE (1.5.x) you’re dealing with a Yun and it Just Works™.

having the same problem on an Arduino Mega. FastLED 2 works fine, 2.1 has black as faint red. Using 2811 pixels. Have tried changing pins, changing pixel strings, same effect. Haven’t figure it out yet.

What version of the arduino ide are you using? It has to be before 1.5.7. The compiler in 1.5.7 introduces some issues w/AVR compilation & asm blocks that affect the library.

Daniel - I was using the 1.5.7 ide, so will go back to the 1.5.6 version and give it a try to see if that works, although I’ve had to give up on the Yun for my project as I seem to be having an overheating issue on the two that I’ve tried (which I initially thought might be my problem with the LED output), which makes it too unreliable for my use case ;o(
So I’ll be using the Teensy, and the FastLED library (using the 1.0.5 arduino ide) works great - thanks!.

I will downgrade and recompile
