Master DALI-2 with STM32F7

[ilcontefabio]

Hi all,

I'm looking for a free library or source C code to develop and application for DALI master manager with STM32F7 board.

I didn't find anything ....

Any suggestion?

Many thanks

Fabio

The question of open source for DALI and DALI-2 comes up from time to time in the community. Apart from very old DALI examples for STM32F1 and STM32L1, there were no further libraries.

However, one of our partners in our Partner Program has since developed solutions that can be licensed from them - but of course, this is not open source: MBS Solutions - DALI Stack (ST partner).

Hope that helps?

Thanks Peter,

you are speaking about this?

https://github.com/tomyqg?tab=repositories&q=dali&type=&language=&sort=

I saw that projects ... I'm new about DALI and I didn't understand how is possible to work as master.

It seems the application runs based on the receive DALI request

Have you ever used that example?

Thanks

Fabio

No, I was talking about the DALI-2 stack from MBS. I’m afraid you won’t find anything even remotely useful in the open source field for DALI-2, because systems using DALI-2 have to be certified by the DALI Alliance.

Good luck!

ok,

many thanks Peter.

Hello all,

I reopen this topic just to know if is there anyone used the MBS DALI library or is there any application examples using their API.

Just to have  look 

Thanks

You should ask MBS that!

I would drop the STM32F7 or even STM32 criterium, and look for any MCU-based implementation.
There are very few MCUs that support even biphase serial protocol modes out of the box, so you have to adapt the HAL layer anyway.

NXP had a DALI implementation and specific eval boards several years ago, not sure if they are abandoned in the meantime.

thank Andrew

you are completely right but I asked just to have an idea about the estimates for using that library from

someone have already used 

Thanks Fabio

A quick Google* search came up with: 

https://www.nxp.com/docs/en/fact-sheet/DALIREFDESIGN.pdf 

https://www.nxp.com/docs/en/supporting-information/RMACSDALIREF.pdf

https://www.design-reuse.com/news/202521945-nxp-brings-arm-cortex-m0-to-dali-and-dmx512-lighting-control-systems/

- is that what you were thinking of?

As @Peter BENSCH suggested, it looks like this isjust DALI - not DALI-2 ?
