ChibiOS Free Embedded RTOS

Hello,

Does an SAI LLD exist for STM32? I see SPI/I2S drivers, but I need to do TDM so will need to use one of the SAIs. Some pointers would be greatly appreciated.

Thanks!

Hi,

There is no SAI support so far. One option is to integrate ST library module for SAI to work alongside ChibiOS HAL.

Hi Giovanni,

Do you know of any contractors who are capable and willing to do this work?

Thanks,
Edison

Hi,

Look for PMs on the forum.

Hi.
I was written SAI driver for STM32G473 some time ago. I do not know is hardware the same for H750 chip.

I know this is an old thread; however I made a poor man's version of SAI Driver; very simple; but not complete. However; it will be a good start

Here you see how it was used to play MP3 files as well

The whole project is here

I hope it helps others.

Hi,

There are several versions around now....

I will try to make an official one out of this.

Hi,

is there some update on this? I would like to use the SAI peripheral on the STM32H723. How would I best go forward with this?

Thanks!

Hello, I have written a SAI driver for ChibiOS but I haven't fully tested it yet.
In the coming days, I will commit a branch with this feature and eventually i will merge it into the trunk.
I will update you by next week.

Thanks, looking forward to it!
