4.3 Sample Programs
Sample programs are provided in the Dynamic C
Samples
folder. The sample program
PONG.C
demonstrates the output to the STDIO window.
The various directories in the
Samples
folder contain specific sample programs that illus-
trate the use of the corresponding Dynamic C libraries.
The
LP3500
folder provides sample programs specific to the LP3500. Each sample pro-
gram has comments that describe the purpose and function of the program. Follow the
instructions at the beginning of the sample program.
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 LP3500
must be in the Program mode (see Section 4.2, “Programming Cable”) and must be con-
nected to a PC using the programming cable as described in Section 2.1, “LP3500 Con-
nections.”
Appendix G, “Running a Sample Program,” takes you through the steps of running one of
the sample programs.

•
DIGOUT.C
—Demonstrates the use of the high-current outputs configured as either sink-
ing or sourcing outputs. Using the Prototyping Board, you can see an LED toggle

Board, you can see a bank of input channels toggle from HIGH to LOW when pressing
a pushbutton on the Prototyping Board.
•
DIGBANKOUT.C
—Demonstrates the use of the high-current outputs configured as either
sinking or sourcing outputs. Using the Prototyping Board, you can see a bank of chan-
nels toggle the corresponding LEDs on/off via high-current outputs.
