Library Compile Issues for the Iridium SPX-16394

SPARK-X
1

I am attempting to use the I2C interface for the SPX-16394 with the Sparkfun Arduino library. I am getting compile errors for the library under Arduino 1.8.13 using the most recent library on a SAMD51 Arduino (Adafruit ItsyBitsy M4).

Help?

Arduino: 1.8.13 (Mac OS X), Board: "Adafruit ItsyBitsy M4 (SAMD51), Enabled, 120 MHz (standard), Small (-Os) (standard), 50 MHz (standard), Arduino, Off"
