Controlling a WS2812B LED

Just some brief notes about LED strips based on the WS2812B (for example this one).
The same LED is also used in the Adafruit circular ring LED (here a datasheet from Adafruit)

Technology changes

The market for embedded development is more and more complex and fast these days.
Every day there is some new platform popping up.
Is quite difficult to stay updated unless you have to do that for work.

MSP430 - Energia and Grove

I do have few Arduino around.
Like many people I bought some of them because ... well, I don't know, I guess at the time it was the news, to see what it is.
And I didn't like it much.
