STM32 MCUs

Hi ST expertSTM32G473cbt6 and STM32G474cbt6 are pin-to-pin compatible, can their software projects be designed into one project?

I have a question regarding your company’s NUCLEO-H753ZI model.I evaluated two boards of this model (let’s call them a and b), and observed the following phenomenon exclusively on ADC channel 2 of board a. [Phenomenon]When we applied various input voltages and measured the output, we found that the output dropped by approximately 800 LSB (equivalent to about 0.04 V) within the input voltage ranges of 0.825–1.65 V and 2.475–3.3 V (1/4–2/4 and 3/4–4/4 of full scale).*The input voltage conditions (accuracy, ripple) were identical across all boards and channels. [Board Information]ADC Channel 2 Assignment: PA3Resolution: 16-bit modeSampling Time: 16.5 cyclesSampling Frequency: 250 kHz (timer-triggered) Since this phenomenon is not observed on other boards or channels, we suspect that some kind of malfunction is occurring. Based on the symptoms, we also suspect a failure within the successive approximation ADC. If you know the cause of this phenomenon, please let us know.Also, if there are

BOARD: STM32H743IITXACTICLE FOLLOWED: https://community.st.com/t5/stm32-mcus/how-to-implement-a-usb-device-composite-in-stm32h5/ta-p/708078Hello everyone,I was trying to use USB CDC+MSC in composite mode. After following the article mentioned above, i was able to build the project. But after running i was able to only get MSC (as shown in pc) and getting the CDC port with windows error 10.Few things i have changed, in usbd_desc.c updated these lines   0xEF, /* bDeviceClass */ 0x02, /* bDeviceSubClass */ 0x01, /* bDeviceProtocol */ Also i have updated CDC_IN_EP, CDC_OUT_EP, CDC_CMD_EP so it should not match MSC_EPIN_ADDR and MSC_EPOUT_ADDR     #ifndef CDC_IN_EP #define CDC_IN_EP 0x82U /* EP1 for data IN */ #endif /* CDC_IN_EP */ #ifndef CDC_OUT_EP #define CDC_OUT_EP 0x02U /* EP1 for data OUT */ #endif /* CDC_OUT_EP */ #ifndef CDC_CMD_EP #define CDC_CMD_EP 0x83U /* EP2 for CDC commands */ #endif /* CDC_CMD_EP */ #ifndef MSC_EPIN_ADDR #define MSC_EP

Hi all,I currently working on a project using TouchGFX, multiple tasks are using functions from <math.h> which are not re-entrant, so I have them mutex protected. The drivers using these functions are written in C.Does anyone know if the TouchGFX library uses any non re-entrant library functions? Do I need to be careful with anything I use in the application?Kind Regards,Anthony 

Hello,I am exploring the possibility of developing a smart floor-cleaning machine for commercial environments.The initial concept may include:Motor control for brushes and wheels Water-level and pressure sensors Battery monitoring Obstacle detection Bluetooth or Wi-Fi connectivity Basic usage and maintenance loggingMy background is in the floor-cleaning industry rather than embedded-system development. Our current business website is https://floorcleaningsydney.com.au/, which provides context about the types of floor-cleaning work and environments the machine may be used in.Which STM32 MCU family would be a practical starting point for this type of prototype?Would an STM32G4 be appropriate because of its motor-control features, or would another STM32 family be easier for an initial prototype?I would also appreciate recommendations for a suitable STM32 development board and motor-control expansion board.

I purchased a brand new Nucleo board. plugged it into my computer, USB device detected, please update firmware; yes; then the process stopped “Error 33” Now my BRAND NEW  nucleo board seems bricked.  Is there any recovery mode?  I have tried several times on STM32 Cube Programmer; The board is detected,      Does anyone have any suggestions? - This does not bode well for my first introduction to ST. What a flaky system. I have changed cables etc, several different combinations, changed USB ports, rebooted, all of the standard stuff.  It seems as though the Nucleo board’s serial number is being detected.  The firmware update process starts, runs for a few seconds, several red LED flashes, then halts and gives error 33.  

Hello everyone,I'm a final-year Electrical and Electronics Engineering (EEE) student aspiring to build my career in the Electric Vehicle (EV) industry, particularly in areas such as Battery Management Systems (BMS), Power Electronics, Motor Control, Embedded Systems, and eventually R&D.I recently decided to learn the STM32 NUCLEO-F303RE as my primary development platform because I understand it is widely used for motor control, real-time embedded applications, and industrial systems.I am a complete beginner to STM32 and embedded systems (although I have basic C programming knowledge), and I'd like to learn it the right way rather than just following random tutorials.I'm looking for guidance on the following:What is the best learning roadmap from beginner to advanced for the STM32 NUCLEO-F303RE? In what order should I learn the peripherals (GPIO, Timers, PWM, ADC, UART, SPI, I2C, CAN, DMA, etc.)? Which official documents should I read first (User Manual, Datasheet, Reference Manual,

We need to use an ST67W611M1 on an STM32H5, running the Zephyr operating system in softAP mode. Currently, the Zephyr driver for the ST67W611M1 only supports STA mode. Is there a roadmap for this feature?Thanks,Denis M.

HelloI have my own board with STM32G071KBT6 microcontroller. I successfully comunicate with charger by PD protocol and I receive up to 21 V (PPS). But I need above 21V. I have power bank with AVS up to 28V and USB cable with e-marker (up to 240W). How to configure the stack to receive EPR parameters? I have no TCPP IC, but I use my own protection circuit. In the trace the EPR commands isn't present. I use STM32CubeIDE 2.1.1 and STM32CubeMX 6.17.0.Thanks a lot and best regards

Hello,another day, another N6 "issue" :)I want to do RAM to RAM copy by HPDMA, but the data never get copied from Src to Dest, Dest always stays unmodified. I have checked the 'DMA_RAMToRAM' example for N6 and went from there, but with no success.DMA Init:__HAL_RCC_HPDMA1_CLK_ENABLE(); HAL_NVIC_SetPriority(HPDMA1_Channel1_IRQn, 0, 0); HAL_NVIC_EnableIRQ(HPDMA1_Channel1_IRQn); handle_HPDMA1.Instance = HPDMA1_Channel1; handle_HPDMA1.Init.Request = DMA_REQUEST_SW; handle_HPDMA1.Init.BlkHWRequest = DMA_BREQ_SINGLE_BURST; handle_HPDMA1.Init.Direction = DMA_MEMORY_TO_MEMORY; handle_HPDMA1.Init.SrcInc = DMA_SINC_INCREMENTED; handle_HPDMA1.Init.DestInc = DMA_DINC_INCREMENTED; handle_HPDMA1.Init.SrcDataWidth = DMA_SRC_DATAWIDTH_HALFWORD; handle_HPDMA1.Init.DestDataWidth = DMA_DEST_DATAWIDTH_HALFWORD; handle_HPDMA1.Init.Priority = DMA_LOW_PRIORITY_HIGH_WEIGHT; handle_HPDMA1.Init.SrcBurstLength = 2; handle_HPDMA1.Init.DestBurstLength = 2; handle_HPDMA1.Init.TransferAllocatedPort = DMA_SRC_ALLOC

Hello,We are using STM32 Motor Profiler to identify the parameters of an IPMSM motor, but the profiling process always stops at approximately 7% and reports a “Driver Protection” fault.Hardware configuration: - MCU board: NUCLEO-F446RE - Motor-control expansion board: X-NUCLEO-IHM09M2 - Power board: STEVAL-IPMM15B -Motor type: IPMSM  Thank you. 

Hello,I noticed that in the STM32Cube_FW_H7_V1.13.0 distribution, the folder \Drivers\CMSIS\DSP\Lib has disappeared.Is there a document available that explains how to compile these libraries, and what are the options and defines to set for an STM32H743?Thank you.

 Hello,We use MB1551 TFM example project on our industrial board. For technical reason, we have modified the card entry point from USART1 to USART3.(TFM\TFM_SBSFU_Boot\Src\low_level_com.c, “COM_INSTANCE”)(TFM\TFM_Appli\Secure\Src\low_level_com.c, “COM_INSTANCE”)The log of SBSFU doesn’t appear on UART target.So next, we are trying to debug TFM SBSFU of a STM32U585 project as shown in this tutorial : We use the SBSFU script “regression.sh” and flash SBSFU, loader, secure and unsecure application with “TFM_UPDATE.sh”.The JTAG connection works correctly to open CubeProgrammer and read option byte for example.Finally, we set the tutorial debug configuration and launch the debug without error. Debug launch but stop with this message :After, we can only stop the simulation or terminate it.  We have couple of questions.First of all, can we come to the conclusion that our MCU is booting ?Secondly, Is it possible to change USART1 to USART3 as we did ?Why do we have break point before the debug s
