116 RabbitCore RCM3400
D.7 Sample Programs
Sample programs illustrating the use of the LCD/keypad module with the Prototyping
Board are provided in the SAMPLES\RCM3400\LCD_KEYPAD directory.
These sample programs use the auxiliary 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), then compile and run it by
pressing F9. The RCM3400 must be connected to a PC using the programming cable as
described in Chapter 2, “Getting Started.”.
Complete information on Dynamic C is provided in the Dynamic C User’s Manual.
• 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.
Additional sample programs are available in the SAMPLES\LCD_KEYPAD\122×32_1×7
