Hello,I will make some probes for reading electrical values (AC, Analog, digital,...), but I'm not sure what happens if I insert a signal to a GPIO when MCU is powered off.I read time ago that all GPIOs are in high impedance state when MCU is not powered but I don't see this information in datasheets. It's the most logical, but I need to be sure for the safety of MCUs.The MCUs that I will use areSTM32F446 (Nucleo board)STM32G030 (Homemade boards)STM32F103 (Blue Pill) Thanks 

We have following configuration in CTRL1: ODR[3:0]: 1001b (High-Performance / Low-Power mode 1600/200 Hz)MODE[1:0]: 01b(High-Performance Mode (14-bit resolution))And the value in the  "LP_MODE[1:0] " might be different depending on the state we came from. The question here does the value in the "LP_MODE[1:0] " have any affect in this configuration when high performance is selected in MODE[1:0]?

Hi! I have built a project in CubeMX for STM32U5A9ZJTxQ and generated the code for Keil uVision5.When rejecting the generated project, Keil does not find the pack with the desired device, offers to manually select the device and gives an error:Error #550: Requested device STM32U5A9ZJTx(STMicroelectronics) not found for target 'U5A9_LTDC' I can select STM32U5A9ZJTxQ myself. However, this has to be done after each code generation, which takes a lot of time.

Hello?As the title states, I would like to inquire about the settings of STM32CUBEIDE(V1.13.1) of the STM32F730V8T product.If you select USB_OTG_FS (Dual/OTG, Host Only or Device only) for the relevant MCU, it will be activated in the clock, but USB_OTG_HS (Dual/OTG, Host Only or Device only) will not be activated no matter which one you select.This means that HS mode does not require an internal clock. Does this work properly?

Hi.I work on BMS. I want a master-slave topology. I want to use 300 slave cards and 1 master card. This BMS is for automotive. I check ST MCU. I guess, The card should be 10-bit I2C. Because I want 300 Slave cards. So, Can you Help me this subject? Which one I will choose?

hi all, I am using STLINK/V2 ISOL which says ST_LINK, No MCU device found, just replacing with STLINK/V2 works keep all setup intact.what could be the reason. 

Hello all,I recently ran into this problem where the MCU would instantly stop working after enabling the DAC. The behavior is that from the debug view of STM32IDE the program is still running, but all variable values are reset to 0, and once the program is paused manually, instead of showing where exactly the program was paused at, it shows a blank window with some HEX address. Below is the DAC connection schematic:The DAC output pin is connected to an op-amp and a bjt to drive the 5 turns coilBelow is the GPIO and DAC init codes: /*TOUT GPIO Configuration PA4 ------> TOUT */ GPIO_InitStruct.Pin = TOUT_PIN; GPIO_InitStruct.Mode = LL_GPIO_MODE_ANALOG; GPIO_InitStruct.Pull = LL_GPIO_PULL_NO; LL_GPIO_Init(TOUT_PORT, &GPIO_InitStruct);static void DAC_Init(void) { LL_DAC_InitTypeDef DAC_InitStruct = {0}; /* Peripheral clock enable */ LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_DAC1); /** DAC channel OUT1 config */ DAC_InitStruct.TriggerSource = LL_DAC_TRIG_SOF

Hello.I am a college student who is using cortex for the first time.I downloaded stm32cube expansion from stm32 and downloaded format is exe file.I downloaded these exe files and installed them on my computer, but there was a problem from here.I downloaded the programs provided by the stm site, such as stm32cubemx and stm32cubeide.But I don't know how to add and build the folder I downloaded with the exe I mentioned above.It's my first time using the stm program and cortex, so I don't know what to do.I don't think I can share the file because the professor asked me to check it out. To make it simple, there were some pdf and txt files in the folder along with the files Drivers, Middlewares, and Projects. (I've read all the pdf and txt files.)In the projects file, there was a folder called nucleo-h743zi -> Applications -> STL on the board I was using, and inside the STL folder, there were 4 project folders that I needed to check.There are folders called EWARM, Inc, MDK-ARM, Src, SW

Hello There,I'm successfully able to run VL6180 with interrupt functionality. But have some functionality queries.The application is intended to generate interrupt when reading a distance below specific threshold. I found that we need to Clear Interrupt bits every time after interrupt is generated. Actually, I don't want to do that as per the application requirement. With that GPIO1 I would be driving external hardware (mosfet to be more precise) directly without involving MCU.So, how is it possible to make the sensor generating interrupts continuously without clearing interrupt bits?Regards,Keshav Aggarwal

In the Battery Charger circuit in STEVAL-SMARTAG2 version, the bill of materials of the C32 capacitor is not available, can you ask the specific model?

I've been having problems with the CubeMX interface for quite some time now, starting 1-2 years before Windows 11 was released.The problem with the interface can appear both after 10-15 minutes of working in CubeMX and immediately after starting the program.I always use the latest versions of CubeMX.The problem remained after:- updating CubeMX;- reinstalling CubeMX;- updating Java SE JDK 16 to Java SE JDK 20;- Updating Windows 10 to the current Windows 11- Changes to video cards gt250 -> rx450 -> gtx960

I am running LED matrix display from F0 Series MCU. At present whatever I want to display on board, I am putting "Hex code of LED matrix" in the main loop code.  But Now I want to have USB stick containing Hex code of LED matrix. Basically user will upload the Hex code on USB stick from laptop.And controller circuit will have female USB connection, where on inserting the USB stick, "Hex code of LED matrix" will automatically uploaded on  external flash such as AT25SF641B, and MCU reads from that external flash to display on LED matrix display.Please let know any tips to implement this.. I am totally lost. 

I have two of the STM32H747I-DISCO boards. I have used STM32CubeIDE to create a simple project for the boards. I followed AN5361 and am able to debug and see the CM7 and CM4 cores running.I've added code to toggle the board LEDs (port I) but don't see any activity - even with an oscilloscope. The IDE did create the code to enable the GPIO clock (__HAL_RCC_GPIOI_CLK_ENABLE() ).I didn't have any trouble getting blinking LEDs on my STM32F407G-DISC1 boards.The issue seems to be that the four GPIO pins for the LEDs are in a high-impedance state even though Pinout View shows that they're all configured as outputs. The pins are floating at between 1V and 2V (with the scope probe weakly pulling to GND). I can alter the voltage on the pins by connecting a 100k resistor from a pin to either 3.3V or GND, so they're definitely floating.I suspect that there is a clocking issue to GPIO Port I, but I'm new to the STM world and don't know where to start.Can someone please point me in the right directi

I am trying to send data over I2C3 Using STM32F429 Dev Board and Everyting works fine except the HEX Data I want to sendI am Passing this function HAL_I2C_Mem_Write(&hi2c3,0x30<<1,0x09,I2C_MEMADD_SIZE_8BIT,0XFF,1,100); And Getting the Following Output on Logic Analyzer write to 0x30 ack data: 0x09 0x08  Why I am getting 0x08 instead of 0xFF?  

I'm totally new to stm32 and arm development, recently got my stm32-f429(ZIT6) discovery kit . I just following some tutorials, but couldn't properly enable SWO printf() like feature, i followed some ITM register enabling codes and nothing works at all. Please someone provide me some codes , FPU settings and guides which i need to do to trace the printf result from ITM FIFO properly. Im using cube mx latest version( 1.6.0 ) IDE.Thank you.

Hi,I have bought the STM32H747-DISCO kit for testing and I want to test at the max frequency (480MHz). I'm aware of the requirements for the 480MHz, I have followed the user manual:Desoldered and soldered relevant SBs for LDO operation.Updated the code to use the LDO, set the 'VOS 0': if (HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY) != HAL_OK) { return false; } __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE0); while (!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) { } HAL_RCC_DeInit(); /* Enable HSE Oscillator and activate PLL with HSE as source */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.HSIState = RCC_HSI_OFF; RCC_OscInitStruct.CSIState = RCC_CSI_OFF; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE; /* PLL1 for System Clock */ RCC_OscInitStruct.PLL.PLLM = 5; RCC_OscInitStruct.PLL.PLLN = 192; RCC_OscInitStruct.PLL.PLLP = 2; RCC_OscInitStruct.PLL.PLLR =

Is there any explanation to how to use production DevEUI, JoinEUI, AppKey and NetwKey, rather than the hardcoded se-identity.h?I have searched all over, application notes, youtube and even studied examples and the actual code, but unable to find out how it is intended to be put together.I tried to populate the LoRaMacNvmData_t passed in OnRestoreContextRequest in lora_app.c, but it is some "BackupContexts" being passed, that seems to be ignored (for this purpose).Am I expected to rely on  FLASH_IF_Read(nvm, LORAWAN_NVM_BASE_ADDRESS, nvm_size);and flash from an external computer, rather than generate it internal to the MCU and report it to external system during test/calibration?

The Device Tree configuration link . https://wiki.st.com/stm32mpu/wiki/STM32_MPU_device_tree does not include scmi.dstiAfter a rough time lot to wade through trial an errors, we were able to reduce the SCMI errors. First we added #include "stm32mp15-scmi.dtsi" and then stm32mp157a-<board>-scmi.dtsi copied from the ev1-scmi.dts but removed i2C4 because this board if quite the same as EV1 but does not use PMIC/I2C4 .  if this is correct change is our biggest guess but it reduced most of the scmi error less one., as follows:The U-boot build failed with:/soc/usbphyc@5a006000/usb-phy@0: Reference to non-existent node or label "scmi_vdd_usb"However, the workshop for STM32MP15 documentation shows the following to be added/* USER CODE BEGIN usbphyc_port0 */phy-supply = <&scmi_vdd_usb>;/* USER CODE END usbphyc_port0 */After searching the whole ecosystem with grep -Rnw . -e 'scmi_vdd_usb'for this definition, only the following 3 files, besides our file,  in the whole EC
