Lib

. The following list of

Dynamic C libraries and library directories will be displayed.

Two library directories provide libraries of function calls that are used to develop applica-
tions for the LP3500.

•

LP3500

—libraries associated with features specific to the LP3500. The functions in the

LP35xx.LIB

library are described in Section 4.5, “LP3500 Function APIs.”.

Two other library directories provide libraries of function calls that are used to develop
applications for the optional LCD/keypad module.

•

DISPLAYS\GRAPHIC

—libraries associated with LCD display.

•

KEYPADS

–libraries associated with the keypad.

The LCD/keypad module functions are described in Section C.7. Other generic functions
applicable to all devices based on the Rabbit 3000 microprocessor are described in the
