@dlloyd, I'm not too familiar with low level programming on micro-controllers. I'll try implementing your one line change tomorrow. But from my understanding is that the SPI library coded the delay, and therefore I can remove/override it with DLYBCT = 0.
I also found this DMA SPI on Github. Would I be able to use it? (I'm trying to understand the arrow notation -> )
Arduino community is awesome, I get answers much faster here than with TI
