Hello,

I'm investigating about how drive a string of this type of LED:

These LED are driven is "Serial" RGB data.

But this could up to 800Khz.

Is any body has already drive this LED with a Kinetis (For me a K60 under MQX 4.2)?

Which method could be beter?

(Gpio, SPI, other??)

With/Without DMA?

The aim is to have CPU charge lower has possible!..

Thank
