Where can I find what kind of hardware is supported by fastspi?
Arduino uno r3, Leonardo for example
https://github.com/FastLED/FastLED/wiki/Overview - scroll down to Supported Platforms
Actually @Daniel_Garcia , that specific link doesn’t work. The document doesn’t have an anchor named “platforms” anywhere. It does however have one called “supported-platforms”. 
Same with “deprecated” versus “deprecated-chipsets” … all of the anchors are like that: they don’t match.
Blah, I’ll have to look into why the markdown anchors aren’t working.
Happy to help if you need a hand. Did plenty of HTML stuff in my previous life.
The wiki pages are all in markdown, I may have simply misread the bit about doing anchors in md.
