About

A warm welcome to all new members joining our community this year!   The year 2025 started with some exciting announcements:   The launch of a new Learning section. The goal is to provide a centralized hub for our learning material (MOOCs, workshops), and to engage with any user who has questions or feedback.  The launch of the Super User Program, which will run on a yearly basis. The Super User Program brings together the most active and trusted members of the ST Community in an exclusive private online area to foster collaboration and offer a privileged communication channel with ST experts.   Also, the ST Community team participated for the first time in a key industry event – Embedded World 2025 in Germany. We met many existing and new community members, super users, and ST experts. It was a truly inspiring and motivating experience to engage with you all face to face.  Now, let us look at your latest achievements and most engaged ar

I just submitted my first topic to the technical forum and had it immediately flagged as spam. I have no idea why this occurred and I'd just like to be able to post my topic. Thanks. 

  

Hi,Please add buttons at the top of a profile that jumps to a forum. And/Or a menu item with list of user selected forums.It takes too many clicks to switch/access forums.Thank you.

Hello,Does anyone from ST actually monitor these forums, and will some of these reported problems get fixed in upcoming releases? or is there another forum or ticket process that needs to get started?

In the past I know that it was not possible to change the email address of an ST account.I use a personal address to be independent of my changes of employers.But now ST requires a commercial email address to participate in webinars.In the same way you impose a commercial address to order on ST eStore.Since ST has tightened its policy regarding email addresses, it becomes imperative to be able to update them.The alternative is to create a "fake" account for each use... I did it but I receive triple notifications and announcements!So how do I change the email address used by my account?

Hello, may be someone can answer the following question:I would like to order from estore a NUCLEO-H755ZI-Q dev board but would like to clarify one moment. The description says: **** On-board ST-LINK (STLINK/V2-1, STLINK-V3E, or STLINK-V3EC) *** If I understand the situation correctly those types of debug./program. are mutually exclusive.  How do I order NUCLEO-H755ZI-Q dev board with STLINK-V3 and not V2? I opened a ticket with Sales/CS on March 6 (Case# 00227964) and so far received 4 replies ranging from "will send it to A, he knows better" to "the board is sold by a third-party distributor, so we dont know ask them" i.e. people have no idea what is being sold through ST web site.What is really upsetting is that on the web page in question https://estore.st.com/en/nucleo-h755zi-q-cpn.html the customers are encouraged to contact sales if they have any questions.   Thanks!

Hi,Firstly, sorry if this is the wrong place to post this, but I have been trying to get into the online eStore to access a sample for the last few hours. Unfortunately, the login button on the store is completely broken. Any attempts to sign in result in:  Error at the ACS Endpoint.invalid_responseReason: The status code of the Response was not Success, was Responder -> Unable to verify the signature I believe there is an issue with the store website specifically since it all works great on the main website as well as here on the forum. Is this a known issue or am I doing something wrong? I even tried buying a part I needed but when I select checkout and sign in, the same error appears.

I am unable to log on to my ST account for two days. The community forum itself reads well, no delays etc.But logging in fails because idpsso.st.com does not respond (browser reports timeout). From my location IP address of idpsso resolves to 164.130.1.34.(Now I've logged in via a proxy with exit point with very good reputation in the USA, but cannot use it all the time).Had tried to redirect either  idpsso.st.com or idsso.st.com, both seem to enable logging in.

Does st has any support for user accounts problems? I have not find anything in the web page. There is no email or any kind of messaging service. I have created a ticket a week ago, but no response there either. It looks like the company went out of business :-/. Was anyone able to get a support from ST and how?

I couldn't help noticing that many posts lately have keywords and/or whole phrases highlighted in bold typeface. This is an entirely new phenomenon, I don't remember seeing this previously, or at least not in such conspicuous proportion.Can please somebody enlighten me, why?Maybe it's not a bad thing, I can't decide yet.Thanks,JW

Why the "wireless MCU" category does not have all the tags as the "normal" STM32s MCUs? If the post is about SPI on STM32WB, I cannot tag it both STM32WB and SPI. All tags for SPI, I2C and so on are available only in the normal MCU category. 

Hi St Forum Team,Randomly, I cannot login to my account.I enter my email and password and click 'Login' button. The page refreshes and the entries are empty. Sometimes it works on 2nd attempt, sometimes not.I tried Chrome and Firefox. This started few weeks ago.Thanks

What is the time zone of the forum. My last complaint is tagged "2024-05-01 5:21:40 AM" while here it is about 12:23:34 UTC 2024. Please tag the posting explicit with the tinmezone!
