@max: the 8 bit version is a great find. Those mcu's are wild bastards.

@alex_m1: ...The cortex-m4 can handle this task...

Very interesting -- and after watching that I saw this one with an 8-bit machine running at only 8MHz...:

Max , according to this:

https://www.youtube.com/watch?v=iOnGcX9Y02Q

The cortex-m4 can handle this task. Probably it's the cheapest way - outside of i/o extenders and a small analog front end if needed , you can a decent m4 for $4 or maybe less.

I believe the teensy-3 is arduino running on a cortex m4. There also a few mbed chips that run on a m4 and are similarly simple.

PSoC is amazingly versatile.  I'm most familiar with the PSoC 4 and especially 5LP: those are the parts with ARM Cortex-M0/M3 CPUs.  For a quick overview of some of the things that you can do with PSoC 4/5LP, I recommend element14's 100 Projects in 100 Days.

@Duane: Here's something you might want to consider for the next version of your display...

That's amazing -- fingers crossed that I don't inadvertantly get a similar effect with the one I'm currently building LOL.

I've never actually used a PSoC... but you make a compelling argument...

A PSoC 5LP would be a suitable choice -

 

here's an example of how to run the popular WS2811 LEDs completely on the programmable logic hardware of the PSoC.

The part also has a couple different ADCs, Op-Amps and Comparators for all your analog front end design.

 

and of course, the Cortex-M3 for processing your data

@GSKrasle: Or how about this...

The world is indeed our lobster (or crustacean of our choice)

Watch this space for Part 4 next week...
