@Greyling - I haven't used the 28X2 but suggest you look at the hspi commands and setup sniper used and look at Manual 1 P34 for HSPI clock and data out connections on the 28X2... Have you tried these? The APA102 is pretty straightforward to drive... clock and data and a variety of speeds - I'm working on some code for old 08M PICAXEs [just to use them up!] - I have with some success.

I remember that I've added 220 ohm resistors in series with clock and data lines from PICAXEs as I had a chip die mysteriously which _may_ have come from some sort of back feed from an APA102 strip while I was changing power around - the resistors don't don't seem to have an effect on the data transmission being ok.
