Looking for STM32 Eval Board with Native DALI Interface Support

[Yaadesh]

Hi,

I am working on a lighting control project and looking for an STM32 evaluation board that supports native DALI interface.

By native support, I mean:

• The MCU or board includes a built-in DALI transceiver or dedicated hardware for DALI communication.
• It has UART or GPIOs pre-configured for DALI timing.
• The board is supported by official firmware libraries for DALI protocol handling.

Does ST offer any evaluation boards or MCUs with these features built-in? Or would I need to implement DALI support entirely in software with an external transceiver?

Any suggestions or guidance would be appreciated.

Thanks and Regards,

NXP had one about a decade ago, but AFAIK they dropped it soon.

I think DALI is just a too specialized niche product to justify investment into development platforms, especially since it involves mostly the lowest-cost section of MCUs. I never came across any general-purpose MCU that natively supported a DALI interface. And basically all DALI products I had been working on at that time used low-cost 8-bit MCUs (MCP or Atmel).
