4.2.6 Using System Information from the RabbitCore Module
Calibration constants for the A/D converter are stored in the simulated EEPROM area of
the flash memory. You may find it useful to retrieve the calibration constants and save
them for future use, for example, if you should need to replace the RabbitCore module on
the Coyote.
The following sample programs, found in the
illustrate how to save or retrieve the calibration constants. Note that both sample programs
prompt you to use a serial number for the Coyote. This serial number can be any 5-digit
number of your choice, and will be unique to a particular Coyote. Do not use the MAC
address on the bar code label of the RabbitCore module attached to the Coyote since you
may at some later time use that particular RabbitCore module on another Coyote, and the
previously saved calibration data would no longer apply.

4.2.7 Real-Time Clock
If you plan to use the real-time clock functionality in your application, you will need to set
the real-time clock. Set the real-time clock using the SETRTCKB.C sample program from
the Dynamic C SAMPLES\RTCLOCK folder, using the onscreen prompts. The
RTC_TEST.C sample program in the Dynamic C SAMPLES\RTCLOCK folder provides
additional examples of how to read and set the real-time clock.
