Yes, exactly. The CS pin is treated just like a digital I/O, but the MOSI, MISO, and SCK are all still SPI0. Updating the library to make it easy to switch SPI buses, like how the I2C bus can be selected, is at the top of my short list.
EBRAddict, is it working for you now?
Thanks,

Your code is fine, thanks for sharing it. I changed the references to SPI1 and it was sending data correctly on MOSI, SCLK and CS pins for Teensy 3.6 SPI1. My issue was with the Sparkfun board which requires a jumper to be cut or else the MISO pin output is shorted to ground.
