STM32 MCUs Boards and hardware tools

Hi, I have one question about this library STM32CubeExpansion_MEMSMIC1_V5.7.0 and PDM moduleIn the example, I tried to find a conversion rate between audio gain and SPLs or Pa. I only found this snippet of code that refers to the amplification factor, which by default is 1.scr/audio_application.h#define AUDIO_VOLUME_INPUT 64Uscr/audio_application.cvoid Init_Acquisition_Peripherals(uint32_t AudioFreq, uint32_t ChnlNbrIn, uint32_t ChnlNbrOut){MicParams.BitsPerSample = 16;MicParams.ChannelsNbr = ChnlNbrIn;MicParams.Device = AUDIO_IN_DIGITAL_MIC;MicParams.SampleRate = AudioFreq;MicParams.Volume = AUDIO_VOLUME_INPUT;MicParams.Tech_MIC= TYPE_SENSOR;if (CCA02M2_AUDIO_IN_Init(CCA02M2_AUDIO_INSTANCE, &MicParams) != BSP_ERROR_NONE){Error_Handler();}}scr/usbd_audio_if.c/* Private functions ---------------------------------------------------------*//* This table maps the audio device class setting in 1/256 dB to a* linear 0-64 scaling used in pdm_filter.c.

After a debug session my nucleo-wl55jc1 dev kit cannot connect to my pc using cube programmer or cube ide.  When i plug it in to my pc i get this error "The interface firmware FAILED to reset/halt the target MCU" in a text file.  LED4 is permanently red.  I have tried to hold the reset button and time it correctly as i assume the debug session bricked my device.    However i have been unsuccessful. I've updated drivers and removed and re-installed all stm32 programs. I am able to update the st link firmware but nothing else.  I have been trying for two days now and i cant seem to find  the solution. Please assist. Thank you !

Hi, i'm working with the SensorTile.box. I installed the ST BLE Classic app and was trying to upload a standard app from Expert View to train the Vibration Monitor. I flashed the V3.4.7 firmware, as this seems to be the stable one from the suggestions, but nothing is working. It keeps failing to upload the app to the device. i was trying to press the "user" button to reset it while the smartphone was looking for the connection. It can find the box, propose to overwrite the file, but after that, i get an error "there is an error loading the App on the board.Please suggest a solution! I'm stuck for several days already.thanks in advance,

Hello,I'm working on a project using the STM32H735G-DK development board. I'm trying to receive audio data from the on-board digital MEMS PDM microphone (U33) using SAI4 Block A in Master Receive mode. I selected PDM mode in CubeMX and configured SAI4_A as Master Receive. SAI4_CK2 is set as the clock output pin, and SAI4_D1 as the data input. I’m using PLL3P as the clock source for SAI4A, set to 49,152. Middleware PDM2PCM is enabled. I’m currently using HAL_SAI_Receive() (not DMA yet), but BDMA is enabled.When I run the program, the microphone always returns a constant value (like 0xFF), or no data at all.Has anyone successfully used the on-board PDM microphone with SAI4 on this board? What is required to activate the SAI4_CK2 clock and receive valid data? Thanks for the help. 

I was using Nucleo-h563zi board in which my application was to run it using external power source so for that i shifted the jumper to E5V to power the board usign external 5V. I was using AMS1117 voltage regulator to convert it to 5V from 12V but accidentaly due to failure or it 12V was given to E5V pin after the LD4 and LD6 led is red and the LD5 is not turning on as usual when the jumper is shifted to STLK for programming.After this when i try to program by changing the jumper to STLK it is detected but while uploading it is showing "No stlink device found"i found that the 5V,3.3V is shot circuited. what is the possible reason and how to repair it.Can you please suggest some way to repair it.

Can't download CAD library of STM32F769BI from the ultra librarian for Fusion360.

Hi,I'm trying to get started with the STM32 NUCLEO-H7S3L8 board to create a USB HS device. I am new to the boot/application split development (also to trustzone) and don't know where to find the right resources to get started. I have tried using the STM32CubeIDE examples importer but keep receiving "failed to copy error" which I don't know how to debug. I have also tried loading the project from the git repo, I can compile and run the boot project but know how to properly setup the application project to run as well.I would really appreciate some pointers on where to find the information to get the CDC_Standalone example running and how to develop with the boot and application.Apologies I can't be more specific, I seem a little out of my depth and don't know where to start!

Hello Team,We have Purchased the NUCLEO-F767ZI Eval board for our board bring up activity.We have configured the SPI with 15Mhz, i can see lot of ringing from the EVAL board which is more than 4 to 4.5V at Clock and MOSI lines can you look into it, any solution for this?We have observed that at the output of the EVAL board no other devices connected to the Eval board.   

Hello All, I am in a process to develop a board for consumer able wearable application, which uses some sensors. So, can anyone help to review my schematic Design. Please let me know, if anyone can help me out in this.   Best Regards, Sakshi 

Has anyone gotten the HyperRAM on the STM32H735G-DK board working with Zephyr?

Hi,I am using an STM32H753ZIT6 NUCLEO board. While powering the board with an external supply, we faced an overvoltage issue on the board.As the user manual reccomends that the board be supplied between 7 to 12 V, we provided it a constant supply of 9.5 V. After a while, the overvoltage warning LED turned on on the board hence the source was disconnected and we found that the voltage regulator on the board was heating excessively. However, even after replacing the regulator with a new one we are facing the same issue. Any help regarding how this can be fixed would be appreciated.Thank you. 

Dear Team,I recently purchased the STM32H7S78-DK development kit for evaluating and testing customization options with the STM32H7S7 series microcontroller.Although I have referred to the user manual and datasheet, I am still facing difficulties operating the board independently. I am using an ST-Link V3 programmer, but I am unsure how to properly connect and program the board.I kindly request complete guidance on the following:Power connection method for the STM32H7S78-DKST-Link V3 connection procedureStep-by-step instructions to flash firmwareAny official tutorials or video links for setup and programmingAny relevant documents or application notesPlease share any available resources to help me proceed with development and testing.

I was using the CAD resources files from ST for the symbol & footprints of STM32N657B0H3Q & STM32647A0 but could find some pins missing in symbols and footprints as given in the discovery kit. So can anyone check and guide on this..I'm attaching the screen shots of symbols from the discovery kit and the symbol downloaded from the CAD resources.The symbol downloaded from the ST CAD resource for STM32N657B0H3Q (For instance PB1, PB2... pins are missing,) similar is the case for the STM32647A0 CAD files from ST CAD resource. The below attached screenshot is of STM32N657B0H3Q discovery kit having all pins of MCU. 

  Hello everyone, I am having a problem with a simple program. My board is a STM32-U575ZITxQ.Using only the USART1 interface, if I try to print the string: "USART1_READY" on my laptop's serial port, I have no problem. However, as soon as I also enable the USART2, I cannot print anything. Whether with only the USART2 enabled, or with both USART1 and USART2 enabled, if I try to print the string with USART2, I cannot. I checked all the settings of the USART1 and USART2 and they are the same (in GPIO, in Parameter setting, etc.)./* USER CODE BEGIN PV */ char USART1 = "USART1_READY:\r\n"; char USART2= "USART2_READY:\r\n"; /* USER CODE END PV */ /* USER CODE BEGIN 2 */ HAL_TIM_Base_Start_IT(&htim4);//ready for trigger at 1 seconds /* USER CODE END 2 */ void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if(htim->Instance == TIM4) { //HAL_UART_Transmit(&huart1, &USART1, sizeof(USART1),HAL_MAX_DELAY); HAL_UART_Transmit(&huart2, &USART2, sizeof(U

Hi All,What is the pin pitch of each connector on STM32H747I-DISCO kit bellow. Pin pitch means the distance measured from the center of one pin to the center of the next pin.・STMod+ connector・Pmod connector・ARDUINO connectorThanks in advance.

Hello ,Does anyone use STM32F429i eval board ?The user manual (shown as the screenshot below) for my F429 eval board says it has 4 USART ,4 UART. But I can only find 1 DB9 male port marked as USART1. Also, when I use CubeIDE to configure USART1, it automatically enabled PB6 and PB7 for TX and RX. But on the user manual , the schematic clearly says RS232_TX for USART1 is PA9, RS232_RX is PA10.  That's really confusing... I am not able to find 4 USART connections, nor can I configure the right PIN numbers for USART1.  I tried to verify the Pin numbers from the github example folder, it seems they don't have the PIN number either.   

Hi,Mouser among other sells the X-NUCLEO-67W61M1 expansion board and also provide a data brief, however the ST website seem to be void  of any info on the board. Have anyone a clue to why that is? 

I'm doing a project with a SD card, but I have not been able to make it work.I'm using an STM32F401RCT6 and a Micro SD Card Adapter (HW-125), I want to connect them via SPI. I've followed several tutorials online, but I haven't been able to get it to work.Do you know any tutorial or resource that could help me?

This question has already been asked and answered for other STM32 MCU series, but unfortunately, it didn't work for me.So, I got a brand-new STM32 Nucleo-H503RB development board to get to know it better before the project based on this MCU starts. And I want to preserve the original firmware on it for further experiments.What I know these days all the software for a particular MCU is packed into the STM32CubeXX series, which includes demo software, but I can't find it in the STM32CubeH5 pack. For example, we have the demonstration for the STM32F0308-Discovery board: STM32CubeF0/Projects/STM32F0308-Discovery/Demonstrations. It does the same thing: when you press the user button, the LED starts to blink faster and faster, and then goes back to the original frequency.So my question is: where can I find the same thing for the STM32 Nucleo-H503RB board?

Installed STM32Cubde IDE on my machine and selected my board.I was expecting some of the pins/peripherals are set by default but as shown in the screenshot they are not.How to fix this issue please?

Hi! I have a STM32U585 board and I'm trying to make a UART loopback test. I tried two different modes:Asynchronous (Full-Duplex) - wire between the TX and RXSingle-Wire (Half-Duplex) - wire looping to itselfBoth worked in similar ways. I successfully was able to handle 1 byte, so this is the code that worked fine/* USER CODE BEGIN PV */ uint8_t tx = 0; uint8_t rx = 0; /* USER CODE END PV */and inside the main function I hadwhile(1) { printf("Sending byte: %d\r\n", tx); HAL_UART_Transmit(&huart3, &tx, 1, HAL_MAX_DELAY); HAL_UART_Receive(&huart3, &rx, 1, HAL_MAX_DELAY); printf("Received byte: %d\r\n", rx); tx++; HAL_Delay(1000); }I could see in the terminal that it was successfully incrementing both tx and rx variables. Now, it all went wrong when I tried to use an array instead of a single byte. This is what I tried:/* USER CODE BEGIN PV */ uint8_t tx[4] = {0x55, 0x12, 0x00, 0xFF}; uint8_t rx[4] = {0}; /* USER CODE END PV */and the main function hadwhile(1)

I have a nucleo H743ZI board and connect to cube programmer, the programmer can only recoginze it is a H7 based MCU but not a nucleo. If i plug in a F103RB and H745ZI (both are nucleo), the programmer can see it is a nucleo board.is there any way to solve or my H743 is cooked.

Hello,I am working on a project with a Nucleo-G431KB. I am using UART1 to receive GPS data (LEA-6S module, 9600 baud, 3.3V) on pin PB7 (RX), and I send data to a LoRa module (Ebyte E32868T20 module, 3.3V,  9600 baud too) on PB6 (TX).I configured UART1 in asynchronous mode with interrupts enabled (USART1 global interrupt active).In my code, I call HAL_UART_Receive_IT(&huart1, &recep, 1) at startup, and I relaunch HAL_UART_Receive_IT at the end of HAL_UART_RxCpltCallback().The GPS sends data correctly (tested with a direct connection) and the lora module works too (tested by sending text every 3 seconds), but on the Nucleo, the UART interrupt never seems to trigger.I give you my main.c and my .ioc fileAny idea what could block the UART RX interrupt on the G431KB?Thanks!

Hi, I have recently purchased a STLINK-V3PWR with the intent of using it to measure power consumption on my board. Previously I used STLINK-V3SET's JTAG port (MB1440 CN2) to connect to my target board.The STLINK-V3PWR only comes with STDC14 connection for target connection, can I remove MB1440 from STLINK-V3SET and use it as an adaptor board? i.e. have STLINK-V3PWR debug STSDC14 -> MB1440 CN1 -> MB1440 CN2 -> target board?thank you very much for your help. 

Hi, Are there any EV (Evaluation) boards available that support GPS functionality? Thank You
