It was the name of course that I'm talking about :-) reminds me of an April 1st edition of Electronics Australia back in the 70's where a bunch of much more believable acronyms were similarly well chosen.
I read the headline and thought that must be another one of Max's ideas :-) neat chip, but I reckon a, ARM M4 could probably do the lot with some tight coding. Of course if you want a low power version difinitely the way to go.
@JAmbrose...Good to see you pushing these very natty chips you make. but it strikes me you have been hiding your light under a bushel - I had never heard of you before now, but will certainly have a look at what you offer.
(I think you need to pay Max a commission if he hasn't already asked :-)
(PS @Max - if this causes you to get commission, I want a cut :-))
@rheslip0: Another approach - use the Teensy 3.1 and audio shield from pjrc.com. You only need one processor which is Arduino compatible so you can use the Neopixel libraries.
Actually, you can't use any-old-NeoPixel library -- the ones from AdaFruit, for example, use low-level assembly code to get the timing right. However PRJC also does a NeoPixel library that drives 8 strips using the DMA Engine.
When I last talked to Paul at PRJC, they were still working on the audio library. I'm delighted to hear that it's finished -- I'm designing my BADASS display in such a way that I'll be able to swap out my first-pass solution (chipKIT + Arduino) for a Teensy 3.1-based solution -- it will be fun to play with that -- but one step at a time LOL
Another approach - use the Teensy 3.1 and audio shield from pjrc.com. You only need one processor which is Arduino compatible so you can use the Neopixel libraries. They have a really nice audio DSP library including up to 1024 bin FFTs for the ARM M4 core. Teensy board about $20, audio sheild about $15. It will blow the doors off your solution:
I'm not associated with PJRC but I am very impressed with their products. I beleive they also have a high performance LED strip driver too.
