basically do whatever you want with this code.
|
|
|
|
This example shows how to configure the debug output from the library.
|
|
Debug shows various packet and status outputs. These prints can be directed
|
|
towards Serial (as in Serial.print) or any other port (Serial1, SerialUSB, etc).

Feel like supporting open source hardware?
