To add the Romeo2 driver to an application:
1. Add Romeo.h and Romeo.c files to project (in CodeWarrior, right click
2. Add line #include ‘Romeo.h’ to main application program file.
3. Add line 'extern unsigned char romeoReceiveBuffer[];' to main
4. Decide which I/O pins in your application will control Romeo2 functions.

This defines the gain of Romeo2's mixer stage.
0 = Normal gain
1 = -17dB (typical)
This #define switches the position of the MIXOUT pin.
0 - MIXOUT at mixer output
1 - MIXOUT at IF input
This define sets the gain of the phase comparator.
0 - high gain mode
1 - low gain mode
