C.6 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 auxiliary I/O bus on the Rabbit 3000 chip, and so the

#define PORTA_AUX_IO

line is already included in the sample programs.
