DALI 2 DT8 Tuneable White software stack

Bill2 · ‎2025-04-16

Does anyone know if there are any software stacks available through ST that support DALI 2 colour tuneable (DT8) control gear devices (LED drivers). I can see that ST have a third party offering from MBS Solutions that claims to offer full DALI2 support but after contacting them they say that it doesn't support any DT8 control gear commands except RGBWAF - which none of my clients are asking for ...

Hello @Bill2 ,

I recommend checking the user manual UM1728.This document provides detailed information on the implementation of the Digital Addressable Lighting Interface (DALI) within the STM32F1xx 32-bit microcontroller family. It should offer valuable insights and guidance for your project.

I had been dealing with DALI and DT8 quite some while ago, but it seems things haven't changed too much.
Although standardized, it seems mostly larger vendors promote and use this protocol.

I would drop the "ST" (or "ARM Cortex") constraint, and check out other implementations as well.
If it's reasonably well implemented, a port of the device type specific logic shouldn't be too difficult.
