Hi everyone,I’m working on configuring the SARADC in the SPC58ECxx using the RLA (Low-Level Drivers) tool. I want to read an analog signal on PE0 / ADC-AN11.In the SARADC settings, I see the following options:SARADC BSARADC 0SARADC 1SARADC 3SARADC 10bit modulesSARADC STANDBYI’m a bit confused about which options I actually need to select. I understand that SARADC0 is the module connected to my pin, but I’m not entirely clear on the purpose of SARADC B and the other options.Could someone clarify:What each of these options actually does.Which options I need to select if I only want to read PE0 / AN11 with SARADC0.

Hello,I am currently developing with the SPC582Bxx controller using the UDE STK Starter Kit for debugging. During runtime, the Program Counter appears to be stuck in a loop, and I am unable to identify the exact location of the hang. Could you provide guidance on how to troubleshoot this? Additionally, if a UDE STK debugging guide is available, please share it. Thank you.

Hello,I am facing a connection issue with SPC5 Flash Programmer version 2.8.1 when using UART communication with SPC560B64.Setup:Target MCU: SPC560B64External crystal: 8 MHzInterface: UCUART::HybridCom/7/UARTSame hardware setup as previously used successfullySPC5 Flash Programmer v2.7.9 works correctly on an older PC, v2.8.1 (and newer) fails to connect.The software stays in “Connection phase starting” and continuously retries, the UART interface LED does not blink. No connection is established.Same SPC560B64 device, same UART interface and wiringAre there any required driver updates, configuration changes, or compatibility notes for newer versions?

In the datasheet it is given at 40MHz the max C_L is 8pF (from AN6027), but the C_L in the design schema has C1 and C2 8pF(UM3305), which gives 4pF, could you suggest me with the external crystal oscillator design. And the range is from 4MHz to 40MHz,  so if for a chosen crystal , should the minimum frequency satisfy this condition ?  

Dear ST Team,Our application need Magnetic information which is returned via message called $GPRMC as format below: $GPRMC,<Timestamp>,<Status>,<Lat>,<N/S>,<Long>,<E/W>,<Speed>,<Trackgood>,<Date>,<MagVar>,<MagVarDir>,<mode>*<checksum><cr><lf> However, Teseo-VIC3DA inside our Testbench can not get such information even after long hours of testing, please kindly refer to attached log file for more details and by the way please kindly guide us how to setting Module for getting such information. Thank you.Here is short extraction:$GPRMC,091446.200,A,1051.01966,N,10647.92288,E,0.1,0.0,111225,,,D*62$GPRMC,091446.300,A,1051.01967,N,10647.92288,E,0.1,0.0,111225,,,D*62$GPRMC,091446.400,A,1051.01967,N,10647.92288,E,0.1,0.0,111225,,,D*65$GPRMC,091446.500,A,1051.01967,N,10647.92288,E,0.1,0.0,111225,,,

Dear ，       Would you teach me how to set SPC582B DSPI 40bit data frame? I use the SPC5Studio-6.0.0-Doyle, you can see my attached picture.The biggest setting of SPI frame is 32 bits.  but the data sheet says "programmable serial frame size of 4 to 64 bits, expandable by software control"Would you teach me how to set SPI frame 40bit?

I am using stellar studio 8.0.0.in Debug perspective, I can only find the Expression view, but cannot find the Live Expression view in "Window--show view". With Expression view, the monitored variable will be refreshed only when pause the debug session,if it has Live Expression view, I can watch the variable value without need to pause.So I want to know if stellar studio have made the Live Expression function or similar functions now?

I am trying to connect to the SPC574K-DISP board through PLS UDE Starter kit to program but am getting a "Can't determine the default communication device! Current selection is ambiguous!" Pop up error message.I followed the Part 7 - AutoDevKit™ detailed tutorial: Debug and release of firmware created with AutoDevKit™ tutorial step-by-step (though I'm using a different board, and I used the RLA IRQ Test Application). To get to this step.I am using a new SPC574K-DISP board for this, it has not been used/programmed since it came out of the box this week, so I can't verify that it's not a board issue. Though, when powered, the board runs it's Blink LED test application.Device Manager shows two instances of "SPC574K-DISP Discovery+" under "Other devices",

I have the SPC5Studio software installed. Installed everything I could find in the Help-> Install New Software. Found two help files in openocd-> docs section in the SPCStudio folder on the C drive. Only one applied, so as far as I know these are the latest drivers. UDE STK 5.2 and UDE STK 221 are both sitting on the desktop and do not do anything.Nothing I have tried has worked, any insight would be deeply appreciated.ThanksMike

Hello,In the AEK-POW-BMSCHAIN example code, I see high-level APIs like: AEK_POW_BMS63EN_GetModule() AEK_POW_BMS63EN_init()But in my AutoDevKit installation, only low-level chain APIs (AEK_POW_BMS63CHAIN_*) are available.Could you clarify:Are the high-level AEK_POW_BMS63EN APIs included in the public AutoDevKit package?If not, are they only available via partner/NDA packages?Should regular users implement high-level functionality using only the low-level APIs?Thanks!

Hi team,I am trying to run BMSCCTX using Pi as MCU. 1. I read the L9963 E and L9963 T datasheets. i found that any 8 bit message wakes up the BMS , i tried sending sample messages like 8 bit zeros and was able to turn on d2 led of bms.if the wake up is done correct, bms should return a default frame of 0x0000000016. But i am not getting it and after 1 min it goes to sleep mode. when i run a code, D2, D8 and D9 lights up, but D7 - for spi is not blinking.2. I also have one more doutb, inside the bms, the L9963 T converts 4 pin spi to 2 pin ISOp and ISOm pins which goes to L9963E as ISOLp_SDI and ISOLm_NCS.Does the output of the L9963 E comes from the same? as it is bidirectional. Or ISOHp and ISOHm are the output pins for L9963E?? 3. If I am using only one BMSCCTX, to get the replies from E should i loopback connect ISOL pins with ISOH pins?4. In AEK-MCU-C4MINI sample projects i see the pins-TXE

Hi team,I was looking through the steps in the configuration of the sample project: AEK-MCU-C4MINI- AEK_POW_BMSCCTX_GUI_Application for discovery.i made my configurations of the cells as per my project and after allocating the setup, it shows the hardwar connections too.Then it shows to edit the pins in pin map editor which i didn't understand. It says to unassign the allocated pins and copy contents and paste but i didnt understand why we do this and how to do this.( From Step 31 of UM3185 manual). Can someone explain this in detail for me to understand... Thank you.

Dears, How can I get SENT SW demo code described in TN1233? Thanks.

 I can use stellar studio to flash the new software when start a debug session, but I want a separate tool to just flash the new software just like Stm32CubeProgrammer.Does Stellar team have made such tools?

I'm looking at using the Teseo modules in a range of RC boats but would like some final confirmation of the RF front end to make sure I am not doing anything wrong.  For the LIV4F I have boiled it down to this setup, with the understanding that the 4F can drive active antennas directly (for external use), and for passive there is an onboard LNA that needs a blocking cap (for mounting on the same PCB).  Thanks for any help! For the LIV3F(L) I am looking at exclusively active antennas (given the lack of on board LNA). From the RF front end point of view does this m

Hello,I’m experimenting with a simple RAM loader for SPC58 loaded through BAF over CAN.The same program runs perfectly when I debug it in RAM using UDESTK, and I’ve adjusted the linker so the code starts at 0x40070000. It initializes CAN, does a few GPIO tests, etc. — all good under the debugger.However, when I upload the same image to RAM via BAF, it starts but crashes as soon as it tries to initialize the clock, and if I skip that, it later crashes on peripheral initialization (CAN, GPIO, etc.).So my question:What are the main things I’m missing for a program executed directly from BAF in RAM?Is there something specific about system/clock or peripheral state that must be skipped or re-initialized when booting this way?Any hints or example references for a working SPC5 RAM loader via BAF would be very helpful.Thanks!— Janis

Dear ST,As you can see from the title we have issues with our SPI connection to the BMS board. We wired everything properly to the BMS connector, checked all the connections, on the MCU-C4mini shorted the JP pins (JP1 and JP2 and JP3 1-2, JP4,JP5,JP12,JP13).We also flashed the pre-built project from AutoDevkit studio (AEK-MCU-C4MINI - AEK_POW_BMSCCTX_GUI_application for discovery) to the MCU.Followed all the steps.We didn't connect any thermistors, and we only have 4, 3.2V LiFePo4 batteries.On the BMS, only the LEDS D2, D8(Blue) and D9 were lit up ~~ we assume the SPI connection is not being established correctly. We hooked up the SPI lines to a osciloscope, please find attached our readings. If needed I can also send a additional osciloscope reading picture.The yellow line is supposed to be the CLK line, we measured from the tiny peak to peak freq of 5MHz, the freq of the whole clock frame was 10kHz.Please advise how to c

Hello AutoDevKit Support Team,I’m setting up an AEK-MCU-C4MINI1 board and I’m unable to get a working debug session through the board’s mini-USB (P2). I’ve read the user manual, followed the bring-up steps, and tried several configurations, but OpenOCD never manages to see the device over JTAG.SummaryExpected: OpenOCD starts, identifies the SPC58 device, and GDB halts at main().Actual: OpenOCD starts but repeatedly reports JTAG scan/IDCODE errors (“all ones”; IR capture 0x3F). GDB then disconnects.HardwareBoard: AEK-MCU-C4MINI1 (power to J2 = 12 V, S1 ON; D10 LED on)Connection: single mini-USB to P2 (no external probe connected to J3)Windows Device Manager shows:Ports

Hello, Is there any application like Power Consumption Calculator (PCC, which is embedded inside the STM32CubeIDE) for SPC5 microcontroller Family?I am using SPC58xCx and SPC58xBx lines and need the current consumption data for microcontroller core, peripherals, and I/Os.Best regards.

Dear ST Support Team,We are currently developing an IoT-based mining vehicle monitoring system, which generates a large volume of operational data that must be stored and accessed locally. Due to this high data size, we are evaluating the use of SD card or eMMC memory, with a stronger inclination toward eMMC as our final storage solution.For structured and reliable file handling, we are planning to use the FATFS file system for read/write operations.We would like to confirm whether the SPC58NH92E7 microcontroller officially supports integration with FATFS on SDMMC/eMMC interfaces. If available, kindly provide documentation, application notes, or official reference examples demonstrating FATFS usage with this MCU. Tool we are using to flash controller:SPC5 StudioAuto devkit Thank you for

Dear Team, @Max VIZZINI Sir, Help us to Solve this issue.We are currently working with the SPC582B60E1MH00Y MCU in our project development. In our application, the ESP32 reads the firmware file from the cloud and sends it to the MCU via UART.As part of our application, we need to implement a Bootloader using UART communication. However, we do not have prior experience with the Bootloader implementation on the SPC58 series MCU. The hardware design has already been completed, and the SPC58 UART is connected to the ESP32 through the LINFlex1 serial interface pins. Kindly confirm whether these UART pins can be used for the Bootloader application. We kindly request your support in developing the Bootloader application for our project. Additionally, if you could share any reference documents or sample projects (UART Bootloader code), it would greatly help us to progress further and improve our de

Hi Team,I am trying to communicate with my bms using raspberry pi.I am using 8 cells in series connected to AEK-POW-BMSCCTX from C0 to C8 (from cell taps-P1 connecter). From the P4 side VIO-3V, Vdd- 5v, GND. I have also connected the MISO,MOSI,CS and CLK of the pi with corresponding pins in bms. Also TXEN-high, DIS-low, BNE-low.Using this run a sample Spi code and there is no correct reply. I just need to know is this connections correct? any extra connections do i have to do?Also after connections, D9,D8 and D2 leds of my bms is light up. When spi is activated D7 led should blink but not in my setup. I hope i get this problem solved.Hardware we’re using now1× AEK-POW-BMSCCTX (one node powered with 8 cells for bring-up).Raspberry Pi with /dev/spidev0.0 enabled.Cell stack: C0..C8 populated (8 cells ≈ 26 V).Two GND_EXT

Hi Everyone, I´m trying to find the BSDL File for SPC56EC74B3C9EEX. Someone can share me the file.? Sincerely, Ruben Gonzalez

I'm looking for ST's GNSS components that I can build a GNSS receiver which can give offline high accuracy. To do this I need to do extra DSP between front end and baseband processor. What RF front ends are actively being produced that gives down-converted IF analog or digital outputs?
