8.5 Software
8.5.1 Sample Programs
? SSTARAD1.C —Demonstrates how to calibrate an A/D converter channel using two
known voltages, and defines the two coefficients, gain and offset. These coefficients are
then read back to compute the equivalent voltage.
? SSTARAD2.C —Reads and displays voltage and equivalent values of each A/D converter
channel. Calibrations must have been previously stored into flash memory before run-
ning this program. See sample program SSTARAD3.C .
? SSTARAD3.C —Demonstrates how to calibrate all A/D converter channels using two
known voltages and defines the two coefficients, gain and offset. These coefficients are
then read back to compute the equivalent voltage and are saved to flash memory.
8.5.1.1 Running Sample Programs
To run a sample program, open it with the File menu (if it is not still open), compile it
using the Compile menu, and then run it by selecting Run in the Run menu. The CPU
Card must be connected to a PC using the programming cable as described in Section 2.3,
More complete information on Dynamic C is provided in the Dynamic C User ’s Manual .
8.5.2 Dynamic C Libraries
The SMRTSTAR directory contains libraries required to operate the Smart Star control
system.
? SMRTSTAR.LIB —This library supports all the functions needed by the Smart Star sys-
tems including Digital I/O Cards, Relay Cards, D/A Converter and A/D Converter
Cards, and serial communication.
Other functions applicable to all devices based on the Rabbit 2000 microprocessor are
described in the Dynamic C Function Reference Manual .
