Examples of sensored X-CUBE-SPN8 motor control with Hall sensor?

I found only more requests of the same in this forum and no answers. Using Hall sensors for motor control is most typical today. 6-step BLDC code example provided in X-CUBE-SPN8 is sensorless only. There are driver files in X-CUBE-SPN8 package specifically made for Hall sensored control (stm32f4xx_hal_tim_ex.c andstm32f4xx_hal_tim_ex.h) but no examples of usage found. Please somebody point to any example. I will keep posting this until somebody who knows will reply.

Thanks in advance.

I had to mention that the X-NUCLEO-IHM08M1 expansion board for which  X-CUBE-SPN8 was made, does have connectors for Hall sensors. So everything was designed ready for Hall sensored control but no examples of code.

I know that many users (if not vast majority) who buy this board will be using Hall sensors, please help all of those.

Is there anybody who used STM32 for sensored BLDC motor control? Anybody in the world used X-CUBE-SPN8 for Hall sensored motor control?   Am I the first user of it for such basic application ?

This forum tagged this question as 'No one else has this question' ! False.  I found 4 more similar questions starting from years ago.

Nobody clicked 'I also have this question' to mine because they didn't see it !  I also did not get theirs when I was searching for these key words while on this site. If I did I'd click on theirs 'I also have this question' (nobody clicked for them either). (later on I found their similar question on google search - what's the difference?). Also possible that they might be out of here because they did not get any replies - people cannot stay here for years waiting for answers   If such general questions about STM product's direct intended usage by the users must be asked in STM sales office, then what is the purpose of the community forum ?

Ok, but nobody has clicked 'I also have this question' on yours.

Suggest you contact your local ST office and connect with an FAE

This is a user-to-user forum, ST's engineering staff generally work corporate accounts directly through the usual channels (sales, support, product reps, etc). They also have a list of contractors/consultants for more hands-on engineering support needs.

The lack of FAE participation here has been lamented for the most part of a decade.

The forum was moved to a new platform ~15 months ago, so of the older posts won't get flagged, without links/cites I'm not going to dig for them. Answers would be dependent on fellow Motor Engineers participating and helping each other, a review of the sub-forum activity should provide some insight into that level of participation, and who the moderation staff are.

Indeed starting a new platform of this nature could be a very long process if people coming here don't see activity. I think this is why I observed in other competing companies forums their application engineers actively participating in answering people's question and this in turn draws many more users to this place (and to their products as well ) and then in turn multiples of other users start answering questions of the newcomers. This explains why the other company making similar products even rewards their employees for helping forum participants answering questions. It is very unfortunate that STM does not go this way - they have very good product line (I mean their STM32 MCUs + Nucleo boards + Cube libraries) . I do believe making this forum active with the help of their employees STM probably could have taken the whole market of motor control...
