1.2 STM32 DALI slave library overview
The STM32F1xx DALI slave library contains instructions for implementing software of the
DALI protocol into STM32 microcontrollers.
The DALI slave library consists of two layers:
• Upper layer (DALI stack layer)
• Hardware layer (I/O pin driver layer)
The upper layer of the DALI slave library (also known as the DALI stack layer), consists of
routines for processing the required DALI commands and other necessary control functions
(including timing control, error management, memory management, and light control). The
hardware layer (also known as the direct I/O pin driver layer), contains the physical layer
implementation. This is necessary because STM32 microcontrollers do not support DALI
communication peripherals.
