chip or card

Hello, I'm very interrested in your solution and have made a few workaround with it. (i am using an arduino to simulate toys like bumpers, beacon, gear, launch ball with ws2812 strip) https://www.youtube.com/watch?v=De68M2_GIjo

I was thinking about multiplexing leds with the kl25z this summer but as my programming skills are limited didnt finalise it.. http://www.pincabpassion.net/t2479p15-wip-mamecab#53269

And as a birthday gift you made it..

Now I wonder what is the solution you think is the better? To buy only the chip and make my own board https://www.sparkfun.com/products/10136 http://tlc5940arduino.googlecode.com/svn/wiki/images/breadboard-arduino-tlc5940.png http://sonicrobots.com/2012/04/24/the-pwm-controller-tlc-5940-the-arduino-and-a-high-current-output-circuit/

or to buy the already made board? https://www.sparkfun.com/products/10616

I am also wondering if the ledwiz side could be ported to arduino?

And last question if you could add neo pixel support to kl25z

An input/output controller for virtual pinball machines, with plunger position tracking, accelerometer-based nudge sensing, button input encoding, and feedback device control.

The sparkfun board looks like it would make the soldering easier if you don't want to design a custom PCB, but otherwise looks equivalent. I guess it depends on the physical setup you have in mind.

I think an arduino port would be possible in principle, but it would be difficult. For one thing, this project makes use of many of the on-board peripherals on the KL25Z - accelerometer, USB, SPI, PWM, ADC. You'd have to supply arduino equivalents. For another, the KL25Z has a fairly fast ARM CPU. I wouldn't want to try running all of these features at once on anything slower. Finally, the libraries are all different, so you'd essentially be doing a complete rewrite. I suppose if you wanted to try as an academic exercise it would be a challenging project, but I can't see a lot of practical motivation for it given that the KL25Z is only $12 and comes in a really nice physical package.

I'm not familiar with neo pixel.
