1.1.3 DALI stack layer
The DALI stack is the higher DALI layer which implements DALI commands, DALI
structures, timing management, and error management according to the DALI specification.
The most important feature of the DALI stack layer is the DALI commands. These
commands are used for:
• Direct light control such as dimming, on/off switching, and scene selection.
• Device configuration to set DALI variables, read device properties, address
assignments, and query device status.
The DALI stack layer is fully implemented in microcontroller software.
