I2S and Low-level drivers (LL)

[Andrew Androsow]

Hello everyone! Is it possible to initialize an I2S interface using LL drivers?There is only one option in the CubeMX (project manager->advanced settings): HAL. Other peripherals (for example I2C, TIM, USART, SPI) have 2 options HAL/LL. Is it any sense to use LL with I2S at all?

Thanks for response!

If it's not an option in CubeMX, it's probably not supported or not finished. LL came after HAL and doesn't have all of its capabilities.

I don't think LL should ever be used, or anything. Either stick with HAL or use your own register-level code. The LL functions are largely renamed register accesses. Your choice, of course.

Hello @Andrew Androsow​ ,

Which device are you using ?

As said @TDK: it's maybe not yet supported, or maybe you are using an old CubeMX version, so you should update it and use latest release.

Hello Imen DAHMEN! The version of my CubeMX is 6.0.1.I had upgraded it (software and libraries) 5 days ago.
