I found in a PDF document called ''STM32 Embedded Software'' following table where just ''2018'' is stated.

Could ST give us please a more exact release date of the STM32H7 LL API (2018 Q2/Q3/Q4)?Thank you in advance.#stm32h7 #ll #h7 #ll-api #lowlayer

Hi,

The H7 HAL to transmit SPI by DMA is ridiculously slow to start and finish transmitting and sometimes fail in a second transfer.

I hope that the LL for H7 be released soon. If not, I will have to do my own SPI API at register level.

Ari.

I have the same problem with many peripheral. But I don't think the LL lib will be released in the near future.

I waiting now over 5 weeks for an answer (here in the forum and also directly to the support), but I don't get any answer. Really sad for such a simple question ...

Finally I got an answer from ST:

Dear customer,

LL API for the STM32H7 will be probably available in Q3/2018 (probably September 2018).
