Hi,In Vbat mode (No Vdd), is it possible to pull up the tamper pins and detect tamper in High-Level.We did it in run mode. We enabled the pullups on the tamper pins which are connected to a detect switch. We detect tamper and erase backup registers when the switch released.But in VBat mode. We couldnt succedded.We are runing Passive tamper with precharge enable and trig on. Only PC3,PF10 and PI2 pins are available on the board for tamper inputs. We configure the tamp block both in Optee and TFA with same configuration.Below is our device tree for both Op-tee and TFA configuration. &tamp {    st,tamp-passive-nb-sample = <4>;    st,tamp-passive-sample-clk-div = <16384>;    st,tamp-passive-precharge = <4>;    wakeup-source;    wakeup-parent = <&exti>;    /* Tamper button */    tamp-button {        tamper-gpios = &l

Hi! I am trying to learn about interfacing with an stm32f405 as a USB Mass Storage Device. My (homemade) development board has an onboard microSD card slot, and so I would like to present the card as my mass storage. I'm running into some problems with this, however, and here are my symptoms:If I set aside the SDIO component of things temporarily, and just try to present the Stm32's 1kb of internal memory as my mass storage, I see a nice "New accessory detected" popup on my mac, and see the stm32 enumerated in Disk Utility. My mac complains the disk is unformatted, and so it is not mounted. But overall this seems to suggest that the USB Mass Storage bit of things is working. When I try to use 1-wire SDIO (and modify usbd_storage_if.c accordingly) I can see the Mass Storage device enumerated in Disk Utility, and it is listed as a fat filesystem, but I cannot mount the drive. I am unsure why. When I try to use 4-wire SDIO, the system isn't recognized at all by my mac. Step

Hi, i just started with STM32G031J6 using STM32G0316-DISCO board. Using CubeIDE i have configured my second LED LD1 on pin PA11After generated the code by IDE, I added sections for flashing these LEDs. LD2 works perfectly, but there is  a problem with LD1 on the PA11 pin (I tried to change it to another possible one on this pin, but it's still the same) looks liek GPIO is not reconfigured to GPIO_Output.Here is the generated code:  #include "main.h" void SystemClock_Config(void); static void MX_GPIO_Init(void); int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); while (1) { HAL_GPIO_TogglePin(GPIOA, LD2_Pin); HAL_GPIO_TogglePin(GPIOA, LD1_Pin); HAL_Delay(1500); } } void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE1); /** Initializes

Hello,I bought STLINKV2 + small board with STM32F103C8T6. I tried to create a simple program - LED blinking - according to example in here:  https://deepbluembedded.com/stm32-gpio-write-pin-digital-output-lab/   and I have STMCubeIDE + MX + others.My STLINKV2 has newest firmware.Compilation of my example algorithm (in IDE) is ok (see below) , programming is ok, but debugging shows me an error:**************************************Target is not responding, retrying...Target is not responding, retrying...Shutting down...*************************************Can someone help me where is problem ? I would like to try "JTAG/SWD debugging funtion" of my program - i.e. functions "stepOver", "stepInto" etc. Program on processor is running ok and LEDs are blinking ok. *************************************STMicroelectronics ST-LINK GDB server.

Hi!I have a project that will not compile due to "error: 'HAL_StatusTypeDef' does not name a type".The project uses STM32H563 and includes file stm32h5xx_hal_conf.h.The HAL_RCC_MODULE_ENABLED and HAL_GPIO_MODULE_ENABLED are defined.When looking into it, I see circular dependency in the includes of header files from this stm32h5xx_hal_conf.hstm32h5xx_hal_conf.h stm32h5xx_hal_rcc.h stm32h5xx_hal_def.h stm32h5xx.h math.h stm32h563xx.h core_cm33.h system_stm32h5xx.h stm32h5xx_hal.h --> (Here function declarations use HAL_StatusTypeDef) <-- stm32h5xx_hal_conf.h Legacy/stm32_hal_legacy.h stddef.h math.h --> (Here in stm32h5xx_hal_def.h is the definition of HAL_StatusTypeDef) <-- stm32h5xx_hal_rcc_ex.h stm32h5xx_hal_def.h stm32h5xx_hal_gpio.h stm32h5xx_hal_def.h ... 

Dear,    We are working on a custom design which has PDR_ON pin floating. The board is already fabricated and assembled.    The part number is STM32H7A3AII6Q.    Please let us know if this has any consequences on normal operation of the MCU and if so, what's the wayout.Regards-Shubhendu

Hi.I am working on evaluation with STEVAL-MKI210V2K. I use Unico to get sensor data, however what I really want is post-fusion data. Looking at other forum questions, it seems like Unico gives a "fusion" option on the left vertical tab. I don't have it (as well as the QVar option).Is it because the product I am using does not have this feature in the HW/FW level?Or am I missing something? Thanks.  

I'm using STM32U083C-DK which contains STM32U083MCT6 MCU. I want to use W25Q32 NOR Flash using standard SPI protocol. For implementing the file system, for my MCU -> Middleware doesn't have FATFS instead it has FileX, LevelX and ThreadX. I couldn't find any relevant reference to implement the file system according to my requirements (STM32U0XX + W25QXX NOR FLASH + SPI) using FileX. I tried by taking some github repos as reference.... like, Fx_NoR_Write_Read_File  which uses ThreadX as well & it uses OSPI (I tried to replicate it for my requirements but it didn't work) and then Fx_SRAM_File_Edit_Standalone (I tried to replicate this also, like FileX Standalone + NOR SPI, but didn't work).So, then I saw SPI_Flash_Uart_Led_Polling_V1.0 which uses FatFS for W25QXX uisng stm32f429igt6 MCU. I tried to replicate this but f_mount() is returning FR_NO_FILESYSTEM error. Anyone know how to fix it?Or it would be really great if anyone guide me how to use F

HiI'm using nucleo_u575zi board. Connected three external switches to PB0, PB1 & PB2 pins.By default, the pins are low, the pins are configured as:   /*Configure GPIO pins : EXT_PIN3_Pin EXT_PIN1_Pin EXT_PIN2_Pin */ GPIO_InitStruct.Pin = EXT_PIN3_Pin|EXT_PIN1_Pin|EXT_PIN2_Pin; GPIO_InitStruct.Mode = GPIO_MODE_IT_RISING; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);   The NVIC is also enabled. The EXT callback is not getting triggered, not sure what is the issue and how to verify that in debug mode whether it's getting called or not, can someone help me to debug and trace what might be the issue.Attaching the main.c and .ioc files below.Thankyou.

Hi,My problem: how to configure DAC so that CPU core clock and DAC kernel clock can be asynchronous (i.e: 250MHz and 70MHz)?Details:- my hardware is based on the STM32H523CET6- configuration:  - SYSCLK (HCLK) running at 250MHz (with PLL1 from HSE=TCXO @26MHz)  - TIM7 generates a 48kHz rectangle signal  - DAC1 is triggered by TIM7 trgo  - PLL2 configured for PLL2R=70MHz- code loop:  - pulling on TIM7 SR's UIF bit (update interrupt flag) until it is set  - clear UIF bit  - toggling DAC out between 0 and 0xFFF0 values  - loop again (infinitly)- results:  - when DAC is clocked by HCLK (ADC,DAC Clock Mux = HCLK): OK :)  => output is toggling with a rectangle frequency of 24kHz (as expected)  - when DAC is clocked by PLL2 (ADC,DAC Clock Mux = PLL2R): KO :(  => output is randomly togglingMy feeling is that the transfert of the DAC out value (DHR12L1 register) does not work if clocks (CPU and DAC ones) are asynchronous. Can you

Any news on when there will be an update to CubeIDE to better support macOS Sequoia?At the moment we need to use a terminal launch hack to get support for debug tools. Would be nice to get a fix for this soon.

Hello,I am facing an issue while implementing USB UVC (Uncompressed) on the STM32U5G9J-DK2 board.The setup works fine with USBD_VIDEO_EPIN_HS_MPS set to 1400U, and I can achieve image output. However, increasing the endpoint packet size beyond 1400U (e.g., up to 4000U) causes the device to stop being recognized in Device Manager.The issue appears during the initialization process, where the ux_device_stack_class_register function in MX_USBX_Device_Init() returns UX_ERROR.This results in the code getting stuck in the following loop:status = MX_USBX_Device_Init(memory_ptr);if (status != UX_SUCCESS){     while(1)     {     }}For my application, I need to achieve a higher data rate, which requires increasing the endpoint packet size. If I can increase the value of USBD_VIDEO_EPIN_HS_MPS, it would allow me to send larger packets, which is essential for achieving my data rate goal.I’ve attached a ZIP file containing my code for reference, along wi

Hi,Our product proposal to a client has at the root of its security an STM32H533 running our OEM Bootloader and Secure Application only.  The Product State will be either Closed or Locked (as yet undecided) and we will be storing encryption keys used to verify the integrity of other parts of the whole system in the OBKey area with HUK encryption enabled.The client has a very competent security team who will be attempting to break our security measures to highlight any vulnerabilities.  Before we've delivered any hardware to them, they've already started some research.  They are not familiar/experienced with STM32 micro-controllers.  They discovered an article where the researchers have been able to reliably corrupt the value returned when the RDP level is checked during a debug session on an STM32Lxx micro-controller.  This attack allows requests to read memory from the device with RDP level 1 active.The article contains the rather frustrating conclusion that "

Hi @Peter BENSCH Greetings of the day!I am using the controller STM32G491MCT for one of my development project. It is given in the datasheet that the VIL of the FT pin is 0.25*VDD & 0.3*VDD. My input signal fall within the range of 0.753V to 3.83V.Considering the worst case 0.25*3.3 which is 0.825V. When estimating noise margin, 0.825-0.753 equals 0.072mV.Could someone clarify whether the 72mV is sufficient to pull the logic low?Anticipating the earliest response.Thanks & RegardsMahalakshmi S

Is there any driver or sample code available M95P32 EEPROM?Can modern MCUs work with this EEPROM in memory-mapped mode?

Hi,If I understand right USART1 is used in STM32H747I-DISCO board for VCOM. I could not find any example for my board. I would like to want for an 8-byte host command using:HAL_UART_Receive_IT(&huart1, hostCommand.buffer, 8); Once a command is received then I process it, I create the answer and wait for the next command. So simple. Noe: on CN13 pin 13 I see the command from my PC on scope, but the HAL_UART_RECEIVE_IT() never receives anything. Can sombody send me a short example?Thanks,Louie

Hello everyone,it was required that my software periodically measures the internal chip temperature for comparison with the externally measured temperature. As the time distances between measurements are several minutes, the ADC is to be completely turned off in between. I mostly copied the code from the LoRaWAN_End_Node example, but the measured temperature is always too low, around 5-6 °C when it should be around 20-21 °C.The ADC code is generally generated by CubeMX.MCU is the STM32WLE5CCU.I've pasted the code here: void MX_ADC_Init(void) { /* USER CODE BEGIN ADC_Init 0 */ /* USER CODE END ADC_Init 0 */ /* USER CODE BEGIN ADC_Init 1 */ /* USER CODE END ADC_Init 1 */ /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */ hadc.Instance = ADC; hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4; hadc.Init.Resolution = ADC_RESOLUTION_12B; hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc.Init.ScanConvMode = ADC_SCA

Hi team, I am new to the STM32 Cube IDE environment and would like to interface and control the VL53L4CX Time-of-Flight sensor using an STM32F030 DEMO Board.

Hello,We are trying to run Tamper block in VBat (Vsw) mode. When we powered off the device, Vbat pin consumes 3 - 5uA from the battery as specified in device user manual.As we understood from the documentation, the source of Vsw domain (either Vbat or VDD) is switched automatically by internal switch harware, so zero power consumtion is expected from battery when VDD is on. In our custom board, when the board is powerd-up, VDD is on, VBat pin's power consumtion from battery increases up to 50-60uA. Any recomendation about hardware or software would be very helpfull.   -The PDRON pin is pulled-up to VDD on the schematics.  - Battery is CR1216 - 3V Lithium Manganese Dioxide- Battery is connected to the Vbat pin directly, no serial diode,resistor, etc...- Battery cahrging feature is not enabled form device tree.

Hello, as the title goes: is it at all possible to enable both DMA and an analog window watchdog (AWD1) simultaneously on the ADC4?What I'm trying to achieve is the following:ADC4 configured to operate in Stop2 mode and triggered by LPTIM1/CH1 (PWM), clocked by MSIK.AWD1 enabled and also in autonomous mode so it works in Stop2 mode and can wake-up the CPU.DMA enabled at the same time and filling a buffer with the ADC4 acquisitions, same channel as the one which has AWD1 enabled, using LPDMA1, also configured to work autonomously in Stop2.I managed to make the first 2 points work and I'm pretty happy with the results: I get an average current of ~ 7 µA (SMPS enabled) in Stop2, with ADC4 sampling at 500 Hz autonomously (triggered by LPTIM1/CH1) and AWD1 working as expected. So that's pretty good.I then tried to implement a DMA transfer concurrently on the same ADC4 channel using LPDMA1, and this is where things go wild. DMA transfers and AWD1 on ADC4 don't seem to play well together. I h

Hi,I noticed on the GUI Silicon Portfolio that the SPI is used by quite a few micro families for resolutions of up to 480 x 272.I was wondering:1. Do you know if SPI for those micros allows refresh without the tearing effect (i.e. refresh of the whole screen at once)?2. If so, at what colour depth? Do they assume 8 bits per colour?3. Finally, are small animations supported without seeing the tearing effect?Thank you
