Waveshare has recently launched the Pico-DALI2 expansion module for ESP32-Pico series boards designed to enable DALI communication for customized control of multiple lighting groups. It is compatible with development boards such as the ESP32-C6-Pico and ESP32-S3-Pico and includes a DALI communication screw terminal for connecting external DALI devices. DALI (Digital Addressable Lighting Interface) is a standardized protocol used for lighting control in building automation systems. The latest version of the DALI2 protocol is better than the old one in that it offers enhanced interoperability, additional features like multi-master configurations, and better energy management capabilities. DALI2 devices can communicate bidirectionally, meaning controllers can send commands and also receive status feedback from lighting devices, allowing for more complex automation and diagnostics. We can get more information about DALI from Wikipedia. We have previously seen the uses of DALI in Texas Instruments MSPM0 Arm Cortex-M0+ microcontrollers as an interface and in Acme CM3-Home [...]
