For JTAG I am using stellar link debugger, and I have to connect this debugger with microcontroller which is powered with other power supply, how to isolate or connect these connections, any digital isolator is suggested for this ?

I have not been able to find any documentation on how to use the StellarStudio tool. Does any publicly exist, or does this need to be supplied by an FAE? Thanks.

 For your information, StellarStudio 9.0.0-LEDS has been finalized and pushed for the environments. (Windows, MacOS, Linux)This version is based on Eclipse 202512 and CDT 12.3.0, with standalone tools using Java 21.StellarStudio Pinmap Configurator (SR5E1, SR6P3, SR6P3E, SR6P6, SR6P7G7 , SR6P7, SR6G7 and SR6G6)Stel

Hello community,I just wanted to know whether you know of a clock tree wizard for SPC58xE.I read in one post some years ago that there is no clock tree wizard for SPC58XE, but is there still none?Is there any possibility to visualize the clock connections? Kind regards Tkorn

I am working with the Teseo-LIV3F GNSS module, I would need to know whether the velocity field it produces, which is a module, is calculated over the x and y dimensions only or x,y and z Thanks for your help

Good morning!I've been working in a project whose purpose is communicate AEK-MCU-C1MLIT1 board and AEK-COM-ISOSPI1 through SPI/isoSPI protocols. At first, I've tried to apply the hardware configurations and script as mentioned in the user manual(UM3187) to exchange 512 bytes between two devices through isoSPI, however I don’t know how reliable the results in debug step are to assure this communication is working properly. Another detail that I've noticed is about disable pin, which stay always turned on, mainly when I select configuration as “micro” in  AEK-COM-ISOSPI1 Component RLA > Application Cofiguration. What should I do to enable AEK-COM-ISOSPI1 board?About the wire connections, I used as reference the board view within AutoDevKit Studio. I’d like to know if there is some connection that is missing, especially about the ISOm e ISOp signals, because the board view doesn’t show if I should to connect the USB port on the computer to debug step, fo

Is there a way to turn the DC off on the RF_IN port on the LIV4 GPS module?  There must be an enable or disable feature available via firmware.  Thanks for reading.Scott

Hello, i am evaluating Teseo-ELE6A module and i would like to know if NavIC can be configured as a "standalone" constelation, without being combined with GPS,Galileo,etc....In the documentation it is mentioned:NavIC (IRNSS) The module is designed to receive and track the L5 (1575.42 MHz) signal provided by the indian NavIC (IRNSS) satellites system. The module can receive and process NavIC (IRNSS) concurrently with GPS, GLONASS, Galileo, BeiDou, and QZSS.But it is not clear if it can work without GPS, Galileo, .... Could someone tell me if this mode is supported and if there any statistics (time to fix, hdop, vdop, etc....) regarding its "efficiency"Thanks in advance for the help

Hi all,to evaluate LIV4F and MAX-M10S, I use Mikroe "GNSS 9" and "MAX" click boards with a passive antenna (Quectel YEGT001W1AM).While the MAX click board with the MAX-M10S gets a fix in less than one minute, the MAX 9 board with the LIV4F doesn't get a fix. Even when starting with an active antenna to get a fix and then switching to the passive antenna, the LIV4F stops operating. Sporadically, the GSV sentence shows then one or two weak (~20) signals while the MAX-M10S has >10 satellites with signals in the range 20..44.From my understanding of the data sheets, both the LIV4F and MAX-M10S should have similar performance without an external LNA, isn't it?Is there any known issue with the Mikroe GNSS 9 click board?Or a possible misconfiguration of the LIV4F I could fix? 

Hi,Could you please provide more details about the Stop Detection Algorithm referenced in CDB-ID 200? The documentation we have contains very limited information about this feature.Specifically, we would like to understand:- What is the purpose of the Stop Detection Algorithm?- How does it work?- What are the configurable parameters and their recommended values?Thank you in advance for your support.

Liv4F module.  Operating voltage range in the data sheet stated 3v-3.3vIn the Manual 1.8v-3.3v  what is true?  Can you fix the documents???

Hello — please help with the following questions about parameters:How should I correctly configure the TCXO frequency parameter $PSTMGETPAR,1245 (TCXO Frequency)?How should I correctly configure the CPU clock speed parameter $PSTMGETPAR,1130 (CPU clock speed)?To improve PPS accuracy, is it correct that the CPU clock speed should be set equal to the PPS Clock?What are the maximum supported values for the PPS Clock and for the CPU clock?

We would like to use the TESEO-VIC3D GNSS receiver as a replacement part without modifying the design.Could you please confirm or comment if the following hardware connections are acceptable for this module?Pin #1 (WakeUP): Pulled-up to VCCPin #4 (WHEELTICK): Not connected (floating)Pin #7 (Reserved): Connected to GNDPin #15 (FWD): Not connected (floating)Thank you very much for any help in advance.

Hi all,While implementation of CanTp, I am getting some errors regarding undefined reference which are shown in the snippet attached. I debugged completely but I am unable to find from where and for what these errors are coming.It would be more helpful if I get some support regarding this issue. Updating MediaThanks,Shiva Shankar.

I've been trying to get the Virtual_COM_Port app running on the combination of X-NUCLEO-LIV4A1A and NUCLEO-U575ZI-Q board and the best I can get is where the app will successfully output the first second's group of NMEA messages to the PC running a terminal emulator program and then it stops.  After it stops, the actual LIV4 module on daughtercard cotinues to run as you can see the RED LED blink pattern change.This happens in all three cases where I:Try running the pre-compiled build of Virtual_COM_PORT .bin file for the U575XI baord under the repository folder.Build the example project under STM32CubeMX, code generate it for STM32CubeIDE, build it and load it to the U575ZI board and run it (either in run or debug mode).NOTE: In this case, I do get one compile warning where I complains about a missing .c file in the Src folder (worked around this by finding it in a different folder, copying and build).Follow the steps

I have been working with both the Teseo-LIV3F and Teseo-LIV4F GNSS Modules. The Liv3 software datasheet contains all of the information I needed to set up that module. The Teseo LIV4 software datasheet is much shorter and seems to be missing some of the content that is in the Liv3 datasheet. Some of the settings such as the FIX RATE, are documented in the LIV3 datasheet, and work the same on the LIV4. But some of the features such as the CPU statistics message, or setting the CPU FREQ, are documented in the LIV3 and work for the LIV3, but do not appear to work the same for the LIV4. I also noticed that the LIV4 has many fields marked as reserved, which the LIV3 has details for and options to enable. Are all of these reserved fields, functions that are not available on the LIV4? For example trying to turn on the  $PSTMCPU message on LIV4 does not work, but that field is also marked as reserved. I also wanted to ask about the constellation combos. We have been keeping it at

Hi, I am looking to use AEK-POW-BMSWTX battery management system for EV related battery management experiments. Please let me know if I can use AEK-POW-BMSWTX with STM32 microcontroller boards. Also please let me know if any other boards are required to perform experiments with AEK-POW-BMSWTX. Thanks and regards

Dear Community,I have a general question. I wanted to use C++ classes in SPC5 Studio to get a cleaner project structure.For this, I changed main.c to main.cpp and included the C headers using extern "C". I also enabled the C++ linker in the Platform Component RLA.The project builds without any issues, but the parsing errors in the editor are extremely annoying. A lot of the code is marked in red even though it compiles fine.Does anyone know what setting I need to adjust to get rid of all these unresolved reference errors in the parser (i presume...)?Kind regards,TKorn

According to a Blogpost regarding the the TeseoVI series from February 2025, ST has already released the TeseoVI family chipsets ("ST is launching today the TeseoVI [...]").Yet, as of January 2026, neither the chipsets, nor the modules or the Evaluation boards are available anywhere.What's the state on the actual release/availability on the TeseoVI modules/devboards?When will at least the evaluation boards be available?I'm specifically interested in the Teseo-ELE6A.

Hi,On the SR6P3C4 page (https://www.st.com/en/automotive-microcontrollers/sr6p3c4.html) there's a databrief. But not much about a datasheet, specification, or any deeper information about the modules associated with it. Is there a way to access those?Also (still related to the first question), the data brief does say something about maximum junction temperature of 165C, with a note:Nominal specification up to 150 °C. Delta specification up to 165 °C.I'm not sure to understand what does the delta specification means.Thank You

Dear ST Team,After successfully setting Teseo-VIC3DA module, we can get message 3 digital axes accelerometer($PSTMDRSENMSG,30) and message 3 digital axes gyroscopes($PSTMDRSENMSG,31) which are returned from Teseo-VIC3DA HW at 15Hz speed. However, 3 raw data raw_x, raw_y, raw_z are unstable eventhough Teseo-VIC3DA is standstill.For more details, please help to refer to 2 attached logs: PSTMDRSENMSG_30.log and PSTMDRSENMSG_31.logOur question here is: why can we not get stable raw value? Do we miss any setting for getting such stable value? Please kindly help to support. Thank you. Please note that, we use below settings:"$PSTMSETPAR,1228,0x2000,2*46\r\n"; //Disable $GPGBS"$PSTMSETPAR,1228,0x40000,2*70\r\n"; //Disable $PSTMODO"$PSTMSETPAR,1228,0x80

hi community  i am using  "AEK-AUD-C1D9031"  board. in this board i had flashed  .WAV files and i had played. the wave files are played using an example code given in the autodevkit. i used an API playsound() this one will give good sound when i had used playsoundwithgain() -> the gain with range (15,17) the sound quality was good with decent amount of volume. but hear i want to control the volume  (0db - 75db),but by using playsound() and playsoundwithgain() i am unable to control the volume( the sound will be very noise when i had used gain in range of ( (0-14) and (17- so...on) ). so is there any alternatives to control the volume of the sound.   hear is the pic of the function which i had used.

Dear St's engineers,I am encountering an issue with the GNSS TESEO VIC3DA module regarding the inability to enable the PSTMDRCAL message output. I have tried the command $PSTMSETPAR,1228,0x800000,1*4F (as described in the CDB table 228, which is used to enable three messages: PSTMDRGPS, PSTMDRCAL, PSTMDRSINT), but as a result, only PSTMDRGPS is being output.
