Thanks for your help, everyone. It turns out, my connections were fine, I just had the wrong chipset selected in Fast_SPI...
So, obviously, I don't know anything about programming, but I'm having trouble finding any basic information or documentation. I just want to be able to control the speed and colour of a simple chase sequence. I'm sorry for asking dumb questions, but is there a chase function built into Fast_SPI that I can use? Is there a very basic guide to using Fast_SPI anywhere?
Thanks again.
