#define USE_ARC_TABLE

This definition:

•

Enables the logarithmic table to be used instead of direct light control

#define OUT_DALI_PORT,

#define OUT_DALI_PIN,

#define INVERT_OUT_DALI,

#define IN_DALI_PORT,

#define IN_DALI_PIN,

#define INVERT_IN_DALI

This set of definitions:

•

Contains DALI Rx and DALI Tx signal assignments to given pins according to user

requirements. The Rx pin must have interrupt capability.

•

Define whether a pin is inverted or not on the user hardware DALI transceiver board

#define DEVICE_TYPE

This definition:

•

Defines the ballast type according to the DALI specification (see DALI specification for

valid ballast type numbers).

#define DALI_VERSION_NUMBER_ROM

This definition:

•

Defines the DALI version

#define PHYSICAL_MIN_LEVEL_ROM

This definition:

•

Defines the minimum light level, which is limited by the ballast hardware capability

(according to the DALI specification).
