C.8 LCD/Keypad Module Function Calls
When mounted on the Prototyping Board, the LCD/keypad module uses the external I/O
bus on the Rabbit 3000 chip. Remember to add the line
#define PORTA_AUX_IO
to the beginning of any programs using the external I/O bus.
C.8.1 LCD/Keypad Module Initialization
The function used to initialize the LCD/keypad module can be found in the Dynamic C
LIB\DISPLAYS\LCD122KEY7.LIB library.
void dispInit();
Initializes the LCD/keypad module. The keypad is set up using keypadDef() or keyConfig() after
this function call.
RETURN VALUE
None.
C.8.2 LEDs
When power is applied to the LCD/keypad module for the first time, the red LED (DS1)
will come on, indicating that power is being applied to the LCD/keypad module. The red
LED is turned off when the brdInit function executes.
One function is available to control the LEDs, and can be found in the Dynamic C LIB\
DISPLAYS\LCD122KEY7.LIB library.
void displedOut(int led, int value);
LED on/off control. This function will only work when the LCD/keypad module is installed on the
Prototyping Board.
