Hello, we are having an issue where our cell voltage readings are drifting when discharging. When there is no current, the voltages all read correctly. However, during discharge, we see that cell 5 and cell 1 have lower voltage readings by about 150mV at 5A. Once discharge is ended, the voltages level off again. I have checked that this is reflected in the registers. These are our filter settings:

Hi,We are currently using STM32H753 and are setting up USB Fifos. There is some contradictory information about the available sizes. AN4879 mentions that the available SRAM size is 1.25kBytes for OTG_FS:In the reference manual RM0433 I can only find 4kB for both OTG_HS peripherials, where OTG_HS1 is used for OTG_FS:

Hi, Can I use lis3mdl as gyroscope as I observe this behaviour while reading it's raw values.Thanks

Hi,Is it possible to open a .ioc project file for STM32CubeMX directly from the Windows command line? If yes, what is the correct syntax?Thanks

Greetings,I am working on a project involving RTC and TAMP mechanism of U5 series MCUs, specifically STM32U585. I have some questions about the working principle of the TAMP pins. In the reference manual RM0456, it is written that the TAMP pins checks if the line is opened or it is shorted (Section 64.1: "Active tamper which increases the security level by auto checking that the tamper pins are not externallyopened or shorted.").I was able to make the open circuit detection work but I couldn't make the shorting detection work, that might be my fault though. The shorting detection is available in U585 right? Also I was wondering how precise is the shorting detection? Let's assume I have a 50 meters long transmission line, can it detect if the line is shorted about 50 centimeters (the line is now 45.5 meters)? If not, how much length of the tranmission line must be removed to make the TAMP pins detect it? In addition, should I do anything to

In STM32CubeIDE 2.1.1, Project Explorer keeps collapsing constantly.This has been a persistent bug for a very long time and is very annoying.Can't ST just fix this since it is based on Eclipse?

Hello, I am using an STM32U585 with STOP mode and FreeRTOS in tickless idle mode. The datasheet says the current consumption should be around 4.5uA, however I am measuring 35uA on my custom board that only has the MCU and some decoupling capacitators. Can someone tell me if I need to add something in the code to lower consumption? Are the datasheet consumptions possible running an RTOS? I will leave my code and measurements in attach: void PreSleepProcessing(uint32_t ulExpectedIdleTime) { /* place for user code */ (void)ulExpectedIdleTime; __HAL_RCC_GPIOC_CLK_DISABLE(); __HAL_RCC_GPIOH_CLK_DISABLE(); __HAL_RCC_GPIOA_CLK_DISABLE(); __HAL_RCC_GPIOB_CLK_DISABLE(); HAL_ICACHE_Disable(); HAL_SuspendTick(); HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI); } void PostSleepProcessing(uint32_t ulExpectedIdleTime) { /* place for user code */ (void)ulExpectedIdleTime; SystemClock_Config(

 Dear all,For the STM32N6570-DK kit, is there a simple tutorial that shows the workflow for integrating a model generated by STM32Cube AI Studio into a project?A simple example would be: if an image is detected, we could turn on an LED on the kit.A guide would be very welcome. Many thanksCheersEmmanuel

Hello to all, I am looking for the min-max humidity working ranges of the STTH10002TV1 diode (in %) as I can't find it in the product specification.Is there a general value for all the ST's diodes? If so, where can I find it ? Thank you for your time, Best regards, 

Hi ST community,I create a simple application using USART1 baudrate 9600 TX pin - PB6 & Rx pin - PB7. I send uart frame each 1 second. J22 connects to CP210x. I see that the RX led of CP210x toggle each 1 second but when I open terminal screen on the laptop with same baudrate, nothing is shown. HAL_transmit return HAL_OK. Tx pin and Rx GPIO pin is configured as default, no pull up and pull down. What is problem here?  void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ if (HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE3) != HAL_OK) { Error_Handler(); } /** Configure LSE Drive Capability */ HAL_PWR_EnableBkUpAccess(); __HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_MEDIUMHIGH); /** Initializes the CPU, AHB and

The data sheet for the G474RE says it has a Memory Protection Unit. The article on how to enable/configure it in STM32CubeMX shows a CORTEX_M# node under "System Core". I don't see that node. Thank you.

I am able to flash the binary into external flash memory successfully. However, I am facing issues with handling multiple binaries and execution flow.Issues:FSBL & Application Binary FlashingI have two separate binaries (FSBL and Application). I am able to flash only one binary at a time.Kindly guide how to flash both binaries properly (same address 0x70000000 or different memory sections like 0x70010000).Jump to ApplicationFSBL should run first and then jump to the Application.Kindly explain how to implement the jump to application correctly and ensure proper execution flow.Project Structure & Peripheral Allocation

We have been using the ST MP23DB01HP microphone to measure the shockwave signature of assault rifles. When comparing the time signal with measurements performed with other microphones (e.g. B&K model 4948), we noticed that the typical N-wave signature looks different with the ST microphone. The initial compression wave of the shock appears negative when measured with the ST microphone, which is counter intuitive. Also, the expansion phase of the shockwave, which appears relatively clean when measured with the B&K microphone, is severely perturbed when measured with the ST microphone. Could it be that the perturbation observed with the ST microphone is of internal nature, e.g. caused by some internal flow due to the shockwave and not properly vented out of the casing? What other possible causes would you see? Exceeded acoustic overload point? Tthe shockwave has very strong gradients, that might interact negatively with the ST microphone.

Hello,I am working on an STM32 USB CDC (Virtual COM Port) device using the STM32 USB Device Library (CubeMX-generated project).My goal is to have the device appear on Windows as a custom COM port name such as:MO3 Device (COMx)However, I want to achieve this without using a custom INF file, since distributing and installing drivers on every PC is not practical for my use case.From my current understanding:The Product String (iProduct) in usbd_desc.c can be modifiedThe Interface String (iInterface) in the CDC descriptor may also influence the displayed nameWindows typically uses usbser.sys and assigns "USB Serial Device (COMx)" by defaultFriendly Name seems to be controlled primarily via INF, not firmwareI have a few specific questions:Is there any reliable way to influence or override the COM port Friendly Name purely from S

When configuring the LTDC Layer Settings for an STM32N6 chip in CubeMX, the Layer 0 - Color Frame Buffer Start Address is missing: This parameter is available with other chips, such as STM32F750:

I am using stm32f756zg. In which i configure LWIP with FREERTOS cmsisv2. I am getting hard faults when ping devices from other devices.It works fine when I change FREERTOS cmsis v1 and increase the default task stake.

When TxRSTU and RETRIG are enabled with CONT disabled, will the timer still trigger a register update when it's counter reaches it's PER value? Since it says in the image below that the PER event is generated but says it re-starts from 0 when it's reset but doesn't mention roll-over, and the image above says it'll update registers on timer reset and rollover. Essentially what I'm asking is does it count as a roll-over when the timer reaches its period value when CONT=0? Since I need to know if it'll update it's registers at the end of it's period or no.

I am using sr6p3e and I tried to access Gicr registers but I got aport exception, I tried several things like check if clock control the module and if there is a protection registers but I didn't find anything, I know that it use axim for interface so I tried to write on another module GTM registers after making necessary configuration but I got sameh issue I check the startup code coming with mcal and found it configure mpu for Gicr and prephiral section and when I apply it in my code it solve the issueI don't need to use mpu, is there another way to access Gicr and gtm ?

Dear Support,Good morning, I have assembled the STEVAL-ROBKIT1 as described here: https://www.st.com/en/evaluation-tools/steval-robkit1.htmlI have followed the assembly instructions as seen here: https://www.youtube.com/watch?v=8fzpv_j343UWhen I switched on the robot and paired with my iPhone application the robot doesn't respond to the manual commands.  For example if I only move forward or only turn the direction or a combination nothing happens:

I am developing using AutoDevKit and SPC582Bxx.When the device wakes up from STANDBY0 to WKPU, it jumps to IVOR0.This occurs when the Trace32 debugger is connected during wake-up.I would appreciate your advice on if there are any specific settings I need to configure in advance.Is this related to the startup code (boot.s, crt0.s)?

I am using an stm32u585, specifically the b-u585i-iot02a development kit board.I set up a basic project using stm32cube ide to test clock configurations. System is clocked from the MSIS at 24MHz with PSC of 1 -> HCLK is 24MHz.I enabled the RNG peripheral, clocked with the HSI48. In the default SystemClock_Config() function I commented out the code related to enabling the HSI48. RNG initialization is left as default.Interestingly, the RNG can still generate random numbers with HAL_RNG_GenerateRandomNumber(). The MX_RNG_Init() function succeeds as well.Reading HSI48ON and HSI48RDY bits from the status registers give both values as 0.How is the RNG still working and generating valid numbers?Another curiosity: In this state, the whole MCU takes less power than if I leave the SystemClock_Config() as generated (explicitly enabling the HSI48). See code snippets below: System clock config
