Why does STM32MP257F-DK not having EMI-filters on RX lines for USB 3.0?Can it be like a common standard that the transmitter TX should always have:AC capacitors ESD protection EMI-filteringAnd the RX does not need anything of those, because it’s assuming that their transmitter already having these implemented?This picture is from mb1605-mp257f-c01-schematic.pdf 

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.

I’m starting FOC code generation for H5 using MCSDKBlocks I am configuring in MC Workbench include , STMH563ZI (Nucleo Bd) and IHM07M1 (Power module), and motor.  I noticed the PWM configuration is not for general purpose, it is specifically configured for L6230 in IMH07M1.But I’d like to configure PWM for general purpose,  such as for the STEVAL-LVLP01 board I have evaluated already, is this possible? Please let me know and thank you for your consideration.

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

Hello everyone.I will use my MCU to acquire big amounts of analog data and transfer them to a host using UDP.As DTCM is 128K and SRAM1 is 368K I would like to store those data in SRAM1. As an exercice I’m trying to configure LwIP in SRAM1.I’ve followed many tutorials (MPU is, I beleive, set correctly) :with a cache protected region where all the LwIP data should be (normally it should only matter when I’ll run this program) I’ve also configure ETH to point to this area :And Lwip is also configured with this same areaAnd the flash script is also set :But when I compile the code directly after importing from cubeMX, I get :Data are not in SRAM1, they are in the DTCM.Am I missing something ? Do I have to set some options in the compiler ?Also I’m a bit surprised to see that 4 descriptors x 32 bits = 0xa0 (0d160) ??? Or F777 descriptors are 40 bits ?Thanks to anyone who will take some time to help me.Best regards 

I need to use 2 image sensors for tracking proposes, it would be nice if I could sync the two cameras.I see that provide configurable GPIOS with signals like PWM/ PULSE/ VSYNC/ START OF FRAME.Is there any application note/ reference design, on how to sync two image sensors ?  Do I need an external PWM for this? or one sensor can be master (to generate pulse) and to provide clock to Slave sensor?Also I would like to now if the two sensors can have the same clock source to sync MIPI clock.Thank you.

Hello,We are designing a custom board using the STM32MP157FAC1 device and need to provide one USB 2.0 High-Speed port.Kindly refer to the attached block diagram snapshot and review the proposed USB interface architecture of our custom board.Please verify whether the implementation is correct and let us know if any modifications or additional recommendations are required for reliable USB 2.0 High-Speed operation.Regards,PS 

In position control mode, when the commanded angleand motion time are not properly matched, the motor speed sometimes exceeds the maximum speed limit. For example, if the motor’s maximum speed is 3000 RPM, after executing the command the motor speed may reach 4000 RPM. Its not generating error that this motion cannot be executed.

I am using STM32H753ZI and trying to bring up Ethernet (LAN8742, RMII) using HAL + lwIP in NO-RTOS  mode. I generated the code using STM32CubeMX with ETH enabled (RMII) and lwIP enabled (WITH_RTOS disabled, static IP). The PHY link comes up and RJ45 LEDs blink, but the board does not respond to ping and no ARP entry is created on the PC (Destination Host Unreachable). I have placed ETH descriptors and RX buffers in D2 SRAM, enabled MPU and D-Cache, verified RMII_REF_CLK to PA1, selected the LAN8742 PHY driver, and I am calling MX_ETH_Init(), MX_LWIP_Init(), and processing lwIP in the main loop. The FreeRTOS-based STM32H743 Ethernet example works, but I specifically want a HAL-only .

Hello Team, We are currently investigating an issue related to the SPI communication between the STPM34 sensor and the STM32F4 microcontroller.At system startup, all values measured by the STPM34 remain stuck at zero. Even when voltage and current are injected using an OMICRON test bench, no measurement values are received or displayed.Several tests were performed:If we power up the system and confirm that the issue is present, then electrically restart only the board containing the STPM34, the communication recovers correctly and the measured values are no longer stuck at zero.We also soldered wires on one of the SPI buses (SPI1). Since there are two STPM34 devices on the board, two SPI instances are used to communicate with each sensor. The purpose was to verify whether the communication between the sensor and the STM32 was correctly established.Interestingly, simply soldering wires on this SPI bus makes the issue disappear for this instance. However, on the second SPI instance,

Is there a version based on the STM32G4 available?Is the firmware package available for download?Best regards

Sidekick is very interesting.Could you make it easier to access, for example by providing a desktop shortcut/icon, or by making it directly accessible from your website's home page, from STM32CubeMX and STM32CubeIDE, or even from other IDEs?

I'm investigating how to change the TX output power for hardware testing.I was able to confirm that the power changes by writing BLE_TransparentMode to the STM32WBA25 and sending the following HCI command via UART.0x01 0x0F 0xFC 0x02 <EnHighPower> <PowerLevel>However, while Table 468 of AN5270 suggests that it can be set up to +6dBm, there appears to be no change in the actual output between setting it to 0dBm and setting it to +6dBm.0x01 0x0F 0xFC 0x02 0x01 0x190x01 0x0F 0xFC 0x02 0x01 0x1FSetting it to a value lower than 0dBm seems to change the output as expected.Is it actually not possible to set it to a value higher than 0dBm?

I have a design with a CR2032 cell connected to VBAT on the STM32WB5MM module. This was set up using CubeMX and there I enabled the LSE.In my code I am able to set the date and time and observe that it increments as expected. However, as soon I power the circuit down and back up the RTC is reset to the default. I have verified that VBAT is 3.1V.I have not yet tried the backup registers.What am I missing?

Finally was able to test STM32CubeMX2 with a NUCLEO-C562RE board.Simple LED blinking project, and here's what I found out. Project bloat:STM32CubeMX2: 26.2 MB of generated data and when compiled 41.1 MB (NUCLEO-C562RE)STM32CubeMX: 4.6 MB generated and compiled 15.7 MB (NUCLEO-C031C6, same functionality) The old STM32CubeMX included only the HAL libraries actually used.The new one dumps everything in.That's a 5.7x increase for a blink LED. Missing Release configuration:Generated CMake project contains only Debug configuration - No Release.Interesting, because the official "MOOC STM32CubeMX2" video at 4:53 clearly shows both configurations.Either something changed or the video is misleading. Creating Release configuration manually requires editing multiple CMake files, including inside the cmake folder — supposedly overwritten on regeneration (in practice, changed only at project creation).Not trivial if you're not a CMake expert.I did it once manually, but then ended up using Claud

Hello, I have been using the NUCLEO-C562RE for my evaluation and due to a mistake I fried the MCU that came with the board, I replaced the MCU with an MCU from the same series. The dev board came with C562RE and I replaced it with C552RE, but after that I am not able to use JLink to connect to the MCU.am I right in assuming that since the pinout of the two MCU’s are same, the MCU’s can be swapped and used ? 

I created an external flash STLDR file for my board, with STM32H750VB chip and W25Q64 QSPI FLASH. After copying the STLDR file to the cubeprographer directory, it can perform normal external flash read/write and sector erase functions. However, when selecting full chip erase, the cubeprographer prompts me "please select external loader before performing external full chip erase". But I am sure that my code contains the correct int MassErase (void) function, and I used the readelf command in Ubuntu environment to read the STLDR file I created, which also includes the MassErase function. But it seems that this function cannot be correctly detected by the cubeprographer. How can I locate the cause and solve this problem?Wishing you peace

I’m working on a new project based on the STM32H5E4, and hit a weird problem, that smells like a CubeMX bug, with PLL3 init.Seems CubeMX is putting out incorrect values for the VCI Range (PLL3RGE bits in the init structure), relative to the comments in the H5 HAL RCCEX header.I’ve got a 12MHz HSE, divided by 3 [PLL3M] for 4MHz, then multiplied by 48 [PLL3N] in the PLL for 192MHz, then divided by 4 [PLL3Q] for 48MHz for the USB 48MHz clock.Here’s it’s generated code:PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_OTGFS;PeriphClkInitStruct.PLL3.PLL3Source = RCC_PLL3_SOURCE_HSE;PeriphClkInitStruct.PLL3.PLL3M = 3;PeriphClkInitStruct.PLL3.PLL3N = 48;PeriphClkInitStruct.PLL3.PLL3P = 2;PeriphClkInitStruct.PLL3.PLL3Q = 4;PeriphClkInitStruct.PLL3.PLL3R = 2;PeriphClkInitStruct.PLL3.PLL3RGE = RCC_PLL3_VCIRANGE_0;PeriphClkInitStruct.PLL3.PLL3VCOSEL = RCC_PLL3_VCORANGE_MEDIUM;PeriphClkInitStruct.PLL3.PLL3FRACN = 0;PeriphClkInitStruct.PLL3.PLL3ClockOut = RCC_PLL3_DIVQ;PeriphClkInitStruct.Ot
