3.2 DALI stack layer functions
The DALI stack layer implements all DALI commands processed on the logical level
according to the DALI specification.
3.2.1 dali.c
These main files contain the most commonly used functions that are called from the user
application. They contain initialization of the entire DALI slave library, DALI slave library
event flag signaling, command execution calls, and reporting of user hardware error.
