This is documented in the readme.txt file included with the software. Specifically, items 2 and 3:

By default the analog to digital and gyro software is disabled.
Perform these steps to get your gyro working:
1) Enable the Initialize_ADC() and Initialize_Gyro() functions in
teleop.c/Initialization().
2) Enable the timer 4 interrupt service routine in ifi_frc.h
3) Make sure timer 4 is disabled at the top of timers.h.
4) Depending on the operating modes you will be using the gyro,
place calls to the Process_Gyro_Data() function in the disabled.c/
Disabled_Spin(), autonomous.c/Autonomous_Spin() and/or teleop.c/
Teleop_Spin() functions.
5) Add gyro bias calibration code that will execute before you
use your gyro. Example calibration code has been placed in
disabled.c/Disabled() that can be used for the competition (this
requires that you use a mode dongle to emulate the field
controller, which will put you in disabled mode for a period of
time before transitioning to autonomous mode). For testing
purposes you can also use the example code in teleop.c/Teleop()
to make sure your gyro is working.
6) Follow the instructions in adc_readme.txt, adc.h, gyro_readme.txt,
and gyro.h for information related to installation and calibration
of your gyro.
7) If building for the 2004 or 2005 PIC18F8520 based robot controller,
you will need to use the adc_8520.c source file instead of adc.c.
The header file adc.h will work with either version.
8) If building for the 2004 or 2005 PIC18F8520 based robot controller,
you will need to enable the ADC interrupt service routine in
ifi_frc.h
