Board:STM32U5A9xxI set the Number of PDO to define = 5 in the cubeide.But after generate code, the code in usbpd_pdo_defs.h, macro:PORT0_NB_SINKPDO is still 1U.I also checked the file usbpd_pdo_defs_u5.ftl in cubeide's location, the macro PORT0_NB_SINKPDO is a value param from cubeide indeed, but it seems not effective. Is a bug?/* Define ------------------------------------------------------------------*/ #define PORT0_NB_SOURCEPDO 0U /* Number of Source PDOs (applicable for port 0) */ #define PORT0_NB_SINKPDO 1U /* Number of Sink PDOs (applicable for port 0) */ #define PORT1_NB_SOURCEPDO 0U /* Number of Source PDOs (applicable for port 1) */ #define PORT1_NB_SINKPDO 0U /* Number of Sink PDOs (applicable for port 1) */ 

We plan to implement a VL53L1X driver based on this API for our Open Source Real-Time OS (community project) and would have to publish the API source code (content of directory STSW-IMG009_v3.5.4/API only) either as part of the GitHub repository of the OS or as a separate GitHub repository to use it as a package.I had to accept the PLLA (SLA0081) to get the VL53L1X ULD API (STSW-IMG009) which restricts the use and the distribution of the code a lot. On the other hand this PLLA (SLA0081) also says that some portions of the licensed materials might contain Open Source Software subject to Open Source Terms.The files in the API itself tell * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS.And the `License.txt` in directory `STSW-IMG009_v3.5.4/API` saysThis software component is provided to you as part of a software package and appli

Hello Engs, How do you calculate the mission profile for the LDO40LPU33RY LDO regulator in an automotive application? Best regards

Split from this thread. thanks to @Ozone @Karl Yamashita, this afternoon I have tried to extend can2.0 to canfd with my project of stm32g474vet6.  I found some strange things, I think there may be a bug of stm32g474vet6 fdcan module. I modifed the FDCAN_TxHeader to FD_Frame and datelength to 64byte. for  FDCAN_RxHeader, almost nothing to modify. then i used an app on PC to send a 64bytes CAN message,  then my code received the 64bytes message and copied to rxbuffer, the rxbuffer had 64bytes data, but FDCAN_RxHeader.datalength is 15. it is not 64.  i think this is a bug of stm32g474vet6, it received 64bytes data but FDCAN_RxHeader.datalength is 15. I have no can tool now (with used by other people), when i have the can tool, i will take screenshot to show the strange thing. hello @mƎALLEm @Saket_Om did you meet FDCAN received 64bytes but  FDCAN_RxHeader.datalength is 15? is there some configuration I miss?   Thanks a

Hello,What options need to be enabled or disabled to work in card reading or card emulation (tag) modes?I am using X-NUCLEO-NFC08A1 and X-CUBE-NFC6. Currently the cards are read, but not emulated (I need to send a link to the smartphone).

Hello,The target MCU is STM32L151ZETx (LQFP144), and the main clock frequency is 32 MHz.Normally, the system operates in Run mode, but I plan to use Sleep mode or Low Power Sleep mode when the supply current decreases.My question is: when entering Sleep mode or Low Power Sleep mode and then returning to Run mode, is it possible to resume execution from the exact code line (or position) where it was before entering Sleep mode, without requiring clock setup or any additional operation?Thank you.

I was trying to deploy YOLO models with NUCLEO-N657X0-Q board, following instructions shown in the README file in the repository "STM32N6-GettingStarted-ObjectDetection"README.md . While using prebuild binaries, it told me to use STM32CubeProgrammer to program several .hex files. And here's the problem:After connected, I choose the "ai_fsbl.hex" file, and clicked "start programming".Then the connection is disabled, with 2 messages saying "connections to device 0x486 is lost" and "failed to download files". The log is shown below:16:51:32 : Opening and parsing file: ai_fsbl.hex 16:51:32 : Memory Programming ... 16:51:32 : File : ai_fsbl.hex 16:51:32 : Size : 59.59 KB 16:51:32 : Address : 0x70000000 16:51:32 : Erasing memory corresponding to segment 0: 16:51:32 : Download in Progress: 16:51:32 : Error: failed to download Sector[0] 16:51:32 : Error: failed to download the File 16:51:32 : Warning: Connection to device 0x486 is lost 16:51:32 : Disconnected from device. After

Hi GuysI am doing a project and I notice that if I unplug the UART cable(FTDI) and then connect it again, there is a chance that there would be mysterious bytes received from RDR. What is more interesting is that the mysterious bytes are actually the messages that was sent out to UART Tx. During the testing, I am not using any UART serial monitoring tool like Putty or what's so ever, so there should not be any inputs to the UART Rx.  But it just happened, not often, but if I repeat disconnect and reconnect dozens of times, then something from UART Tx got into the UART Rx buffer. I have confirmed that those mysterious bytes are read out from RDR. Has any one know what's happening ?  Thanks.

The goal is to test the Adafruit Gamepad QT with the Nucleo-G071RB board. This requires using the Adafruit seesaw C++ library of source files, which transmits analog joystick signals using the I2C protocol.I used the code example I2C_TwoBoards_ComPolling (C-code) as a starting point an...Added both the Adafruit seesaw and BusIO libraries (C++ code) to the project,Updated the Project Include paths,Added the library paths to the Project Source Locations (Figure 1), andRenamed the main.c file to main.cpp.Problem: the project does not built the Adafruit libraries, the compiler just ignores them.What is the solution for this? How do I build the entire project, including the Adafruit libraries? Thank you!!!Figure 1. 

Hi Everyone.We are using ST25R3918-AQET in our product. But this IC shortage in recently, so we want to find an Alternative part that can match with ST25R3918-AQET and doesn't change anything related to FW or PCB design.We appreciate your support in this case, because this will impact our production.

I tested the LSE CSS function on the Nucleo-L053, but I found that short-circuiting the crystal oscillator pins failed to trigger the CSS interrupt. The code configuration is as follows plz give a clue or the flow of LSECSSvoid SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1); /** Configure LSE Drive Capability */ HAL_PWR_EnableBkUpAccess(); __HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW); /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDef structure. */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_LSE; RCC_OscInitStruct.LSEState = RCC_LSE_ON; RCC_OscInitStruct.HSIState = RCC_HSI_ON; RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT; RCC

The Reference Manual for L4 series (RM0394) says on page 1007:"When the LPTIM is running with an asynchronous clock, reading the LPTIM_CNT register mayreturn unreliable values. So in this case it is necessary to perform two consecutive read accesses and verify that the two returned values are identical.It should be noted that for a reliable LPTIM_CNT register read access, two consecutive read accesses must be performed and compared. A read access can be considered reliable when the values of the two consecutive read accesses are equal."1. What does "asynchronous clock" mean?2. The block diagram, Figure 337 on page 988 shows a "Synchronization" block but is vague as to what this pertains to.3. Also, what is meant by "kernel clock"?  If I am using the LSI oscillator for the clock source (CLKMUX = 0), where does this "lptim_ker_ck" come from?  How is this mapped to LSI clock?  This is confusing.4. If the LPTIM1 is being fed by LSI clock, does the caveat page 1007 still

I'm experiencing FDCAN Memory Access Failures on the STM32H503KBUX during CAN Rx. I am also experiencing intermittent CAN Rx message drops (every 1 in a 200), and I believe the two are related since no others errors are firing. I know the drops are happening on the STM32 because I can see the messages on the bus with my CAN debugger and there are no error frames. I'm struggling to understand why this Memory access error is happening and how to proceed with solving it. The only info I can find is in rm0492. However, it doesnt really say what might cause these events to happen. Other relevant info:- Using internal clock- Freertos- Using to `HAL_FDCAN_RxFifo0Callback` to read from FIFO- Config hfdcan1.Instance = FDCAN1; hfdcan1.Init.ClockDivider = FDCAN_CLOCK_DIV1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan1.Init.Mode = FDCAN_MODE_NORMAL; hfdcan1.Init.AutoRetransmission = ENABLE; hfdcan1.Init.TransmitPause = ENABLE; hfdcan1.Init.ProtocolException = EN

I am having a problem reading SPI data on an STM32F407 where it always returns 0x00. I actually have this working using HAL on the same hardware, however for legacy reasons I need to get this working with SPL. This application is just sending clock signals to the slave and reading the received data. There is no activity on MOSI.I can scope the signals and see the expected traffic on the SCK and MISO so I at least know my clock transmit is working. I just can grab the correct read data. Here is my code. I feel like I'm missing something basic for SPL. Any insight would be helpful.#include "main.h" #include "stm32f4xx_spi.h" #include "stm32f4xx_usart.h" #include "config.h" #include "board_init.h" #include "gpio.h" #define TIMEOUT_TIME 1000; uint16_t SPI_TransmitReceiveByte(uint16_t data); uint16_t spiData; void main() { uint32_t loopCounter = 0; SystemInit(); init_IO(); SPI3_Init(); powerOnLED(); while (1) { loopCounter++; if (loopCounter == 10000) { spiData = SP

Hi there,According to the STM32H755 datasheet, the Cortex-M7 frequency can reach up to 480MHz.However, when I configure the sysclk in STM32CubeMX, it shows the maximum frequency is 300MHz.What's wrong with my config? Or is there any misunderstanding by me?Thanks for your help!  

I'm trying to go about creating a USB Audio interface on a NUCLEO-H7S3L8, receiving USB audio and forwarding it to the SAI, in order to send to an external DAC.Among other tests, I went back to checking when the functions in usbd_audio_if.c get called, to set up transfers of the packets received.And while in a previous version of the same project, on audio playback on the host, AUDIO_AudioCmd_HS() was called, allowing me to continue handling data accordingly, after a Cube MX update (6.14->6.15) and some changes on DMA (to get circular -> non-circular) and SAI (Output Drive enabled) settings, it no longer gets called on playback (a breakpoint within it never gets reached).Following the IRQ handler function for USB on either playback or idle, it only ends up within the code block for handling an incomplete "ISO OUT Interrupt", reaching the "__HAL_PCD_CLEAR_FLAG(hpcd, USB_OTG_GINTSTS_PXFR_INCOMPISOOUT)" macro.Since the changes I've made ever since it was functional seem mostly

According to some reference it is good to have ground polygon under IC 1. Is it okay to have ground polygon under IC? 2. Does it effects heating issue?3. I saw two hole behind the IC of nucleo 144 board. What that mean? 

Hello ST Team,I am currently working on a project that integrates the ST25R3916B NFC reader, and I would like to study and reference the PCB design of the X-NUCLEO-NFC08A1 evaluation board.Could you please provide the Altium Designer project files (.PrjPCB, .SchDoc, .PcbDoc) for this board?I have already checked the official product page, but only Gerber manufacturing files, schematic PDFs, and BOM are available. I would like to obtain the editable Altium source files for learning and integration purposes.Product page reference:https://www.st.com/en/evaluation-tools/x-nucleo-nfc08a1.htmlThank you very much for your support!Best regards,Martinsunyinuo62@gmail.com

Hello Everybody,Here are the software and boards in this case:1. MC workbench 6.3.22. NUCLEO-F401RE3. X-NUCLEO-IHM08M1I try to use the boards to obtain motor parameters. While other parameters were acquired normally, I encountered an issue with the Hall sensor parameters. When connected to two different motors, both returned errors indicating that H1 and H2 were not connected (as illustrated in the picture). However, the motor-board wiring is confirmed correct, and during motor rotation, normal voltage signals are present at the H1 and H2 pins of the motors. What could be causing this error in the Motor Profiler? Thank you. 

Hello everyone, I need to install the firmware support package for STM32H7 series offline. On the website (STM32CubeH7 | Product - STMicroelectronics), I found both the "STM32Cube MCU Package for STM32H7 series" and the "Patch for STM32CubeH7". What is the difference between them ?

On my current board the STM32G030 is getting very hot.  I have even tried a board with no connections to the processor and all pins set to analog.  I have checked the power supply and it's 3.3V.  The board runs OK but I am worried about the processor temp.  I have attached a schematic of the board.  Could something internally be configured to cause this heating?

I'm developing a project using an STM32 Nucleo board. At the core of this project is a UART-based communication protocol running in interrupt (IT) mode — not polling or DMA. This protocol is responsible for controlling multiple subsystems such as a relay module and a fan speed controller.However, most of these subsystem modules were previously written in polling mode.My question is:Can I integrate these polling-based modules into my current UART IT-mode communication system without causing issues? Or should I consider converting them to interrupt or DMA mode to prevent CPU blocking or communication delays?Additionally:What should I watch out for to ensure the CPU doesn't get blocked and UART interrupts don't get delayed in this mixed-mode setup?Extra context:There are 20 NTC temperature sensors in the system, and temperature from all of them is read once every second using ADC. The highest temperature value is selected and stored in a variable. Based on this value, the fan speed is adj

I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could get a green ACK indicator. The results were:Only cell 1 showed a voltage, but it was incorrect (5.8 V).When I try to write or read any register, I receive an ACK, but the register value does not remain as written.I also tried to connect VBAT (P2-15) to C14 (by soldering R22) and GND (P2-9 or 23) to C0, but in this configuration the device does not start and the D13 LED does not blink. I tried several times, resetting all the power supplies in different sequences, but I still could not communicate with the device.I have not been able to start the IC using only the battery or to read the correct voltage values. Any tips would be really appreciated.

Hi! Im doing my project using mpu6500 and I use hal_i2c_mem_read to read the WHOIMI register at 0x75 with the device address 0x69 (AOD to vcc) and I alway get the value 0x00. Why is that? is this module require something soldered to this pad (img) to turn on i2c protocol or what, please help me out.
