C.8 Sample Programs
Sample programs illustrating the use of the LCD/keypad module with the Prototyping
Board are provided in the SAMPLES\RCM3200 directory.
These sample programs use the external I/O bus on the Rabbit 3000 chip, and so the
#define PORTA_AUX_IO line is already included in the sample programs.
Each sample program has comments that describe the purpose and function of the pro-
gram. 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 RCM3200 must be in
Program mode (see Section 4.3, “Serial Programming Cable”), and must be connected to
a PC using the programming cable as described in the RCM3200 Getting Started Manual.
More complete information on Dynamic C is provided in the Dynamic C User’s Manual.
The following sample programs are found in the SAMPLES\RCM3200\LCD_KEYPAD folder.
• KEYPADTOLED.C—This program demonstrates the use of the external I/O bus. The
program will light up an LED on the LCD/keypad module and will display a message
on the LCD when a key press is detected. The DS1 and DS2 LEDs on the Prototyping
Board will also light up.
• LCDKEYFUN.C—This program demonstrates how to draw primitive features from the
graphic library (lines, circles, polygons), and also demonstrates the keypad with the key
release option.
• SWITCHTOLED.C—This program demonstrates the use of the external I/O bus. The
program will light up an LED on the LCD/keypad module and will display a message
on the LCD when a switch press is detected. The DS1 and DS2 LEDs on the Prototyp-
ing Board will also light up.
