+  Configuring the GNSS to automatically send position reports over I2C and display them using a callback
+  By: Paul Clark
+  SparkFun Electronics
+  Date: April 15th, 2022
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows how to access the callback data from the main loop.
+  The simple way to check if new data is available is to use a global flag: set it in the callback, check it and clear it in the main loop.
+  Or, you can be more sophisticated and use the callback flags themselves.
+  This example shows how to use the sophisticated method.

+
+  Hardware Connections:
+  Plug a Qwiic cable into the GPS and a BlackBoard
+  If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
+  Open the serial monitor at 115200 baud to see the output
