3.3 Enabling/Disabling XBee (optional)

Configuration of XBee can be done in .../Doggo/src/config.h.

3.3.1 Enable

Ensure that line 28 (#define USE_XBEE) is not commented out.

- // #define USE_XBEE
+ #define USE_XBEE

3.3.2 Disable

Comment out line 28 (#define USE_XBEE).

- #define USE_XBEE

This can be done to test the motors through USB when the XBee is not configured/connected yet.
