I have been attempting to control an interface from my Sparkfun 9DOFRazor to have the interface reflect the status of variables stored in NV RAM on startup.
I modified the Example SendToMLP by inserting a define statement :
#define SX SerialUSB and replaced the statement Serial.begin(9600) with SX.begin(9600).
With this choice of an output port, the example does not work and does not generate any activity in the Serial Moninitor.
What must I do to get this to work on a SerialUSB interface.
