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)
