Using an APA102 LED string (DotStar)

In case anybody finds it useful, I have written a guide to using APA102 devices (including DotStar, Blinkt etc.) with MicroPython on the micro:bit on http://www.smythe-consulting.com/2017/0 ... -with.html.

Could you link to the article directly? The link you pasted will probably become outdated as soon as you write a new article...

Thank you. That's a really nice introduction to using the SPI peripheral. One note: I think that you can remap the SPI to use pins 0 and 1 (or 1 and 2), and then you don't need all those connectors -- you can connect the cables with crocodiles or bananas, or just wrap the wires around the holes and have the whole thing really compact.
