  • I ended up finding the issue: pins 10 and 9 are, by default, reserved for NFC use and therefore cannot act like GPIO pins. One option is to disable them in the code, another is to just not use them. Switching the CS pin to a different GPIO fixed the problem.

  • The SPI interface does not appear to work. I attempted to communicate with the LSM9DS1 breakout, with no success.
