Hi Awesome People! I was wondering if anyone had a sense of the performance penalty of running multiple controllers on an Arduino DUE. Ideally I would like to run 20-24 strands separately. I’ve been using Atmel arduinos and finally got two Due’s “Duel Due” to play with. My main concerns are latency and FPS. Currently I’m running Arduino 1.5.5 as 1.5.8 was not working for FastLED. I’m guessing since the ARM clocks so much higher that perhaps running a bunch of strands at the same time might not slow things down too much… But I donno! FYI also I’m using an arduino ethernet shield to send the data from MaxMSP doing audio responsive stuff. Thoughts?
What types of LEDs and how many ? Locus is driving 24 strands of LEDs (120 leds per strand) off of a due using parallel output which takes care of a lot of the extra overhead - but that’s not publicly released yet.
(Also working on parallelizing spi based chipsets as well 
Also, I think 1.5.8 should be fine to use with the Due - the problem with 1.5.8 is the compiler messes with the assembler that i’m using for AVR (but I don’t think it will make a big difference one way or the other for you
Using ws2811/2812. I do seem to be having some weirdness with FastLED 2.1 and the Due under 1.5.8, but i’m currently in break things, set them on fire, run away and find something that works mode so no proper issue submission 
The big problem (and the reason for parallel output when I did locus) is the ws2812s absolutely suck as a controller. The 800khz data rate means 30us per rgb led that you have 
I can’t wait for them to die off.
What do you think of the APA102 ? Since the speed is higher because of the separate clock line (but still everything in one package). I just ordered one meter to test.
I have two sets of apa102s that I want to speed test this weekend. The docs say 1mhz but I’ve heard claims it can go as high as 8. I’ll report back after I run my tests, but these may take over from the ws2812 as my go to default chip.
This is the version in the same package as the ws2812 isn’t it? I was also curious about the other package, especially because it seems better designed for heat dispensation. I didn’t came across it when placed on a strip (probably because the price is almost the double).
