 Hello everyone, I am using the STM32F042K6 for a small project where I don't have much space. Therefore, I rely on the small package and the "crystal-less USB" function. The hardware arrived today, but unfortunately, I had to realize that the USB library seems to be too large for the chip. I created a new, empty project in CUBE IDE, with only I2C and USB (COM PORT) enabled, and I get the following error message: "c:\st\stm32cubeide_.2.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.200.202301161003\tools\arm-none-eabi\bin\ld.exe: Test_Project.elf section .data' will not fit in region FLASH' c:\st\stm32cubeide_1.2.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.200.202301161003\tools\arm-none-eabi\bin\ld.exe: region `FLASH' overflowed by 12 bytes"  This is quite frustrating when it is advertised and then doesn't work "out of the box."

"C5" typo corrected in title to "C0"Does have the STM32C5 and STM32U5 microcontroller documents e.g hardware user manual?Could you please help me to confirm this?

Hello,I had two related questions to clarify - 1. Can multiple Op-Amps be used in the differential mode simultaneously and their output fed to ADC for measuring input DC voltage?2. Also, since the Op-Amps inside the STM32G4 MCU are not rail-to-rail, they only output 0-3.3V for the given input. I am only interested in measuring DC input. Connecting the Op-Amp GND to system ground (0V) would give me the full range of output for DC (NOT 1.65-3.3V, but 0-3.3V), right? Thanks.

    I want to try the VL53L7CH, I purchased the SATEL-VL53L7 and the x-nucleo-53l7A1. When I look at the boards on the SATEL-VL53L7 they look identical. But the description says it supports both the CX and CH models. Can someone clear this up?

Hi,I,m looking for a way to remove or hide the keychar of the keyboard's keys or button, i'm using the custom keyboard from TouchGFX demo or examples, and i have a new asset that already have the keychar or key label. For this reason, i need to remove the keychar and prevent the keyboard class from drawing them.How i can do that?Best regards.

Hi Expert, Good day. Refer to the attached label image. One label shows MSL 1 and the other shows MSL 3 for MPN LIS2DW12TR. However, the Reliability Evaluation Report for this P/N indicates MSL 1. Both labels have the same COO but different MSL levels. Is it possible or Is there any PCN behind this change? [images deleted by a moderator] Looking for your support on this.   Thank you.

Hi all,Board: STM32H745I-DISCOIDE: 1.16.1 I am facing some issues with trying to execute code on the SDRAM. I have a 2nd stage bootloader that loads the user application onto QSPI located at 0x9000 0000. After that, I copy the user application code to the SDRAM 0xD0000000. This part works as verified in the debugger. However when I try to jump to the SDRAM address, my program is not executing. And it seems like the SDRAM has lost connection? Attached below is the image(sdram_becomes_unreadable.PNG) where my bootloader jumped to the SDRAM address but unable to read from the SDRAM. There is no hard fault.. Background: I have tried to load the user application onto QSPI and jump to the QSPI address, my program executes successfully. I have checked my MPU configuration to make sure that SDRAM is MPU_INSTRUCTION_ACCESS_ENABLE. Below is my MPU configuration  void MPU_Config(void) { MPU_Region_InitTypeDef MPU_InitStruct = {0}; /* Disables the MPU */

Hi, I am reaching out to kindly request NUCLEO-C051C8 project files ( It seems that ST uses Altium).Altium files would greatly facilitate my development.Please help me.

Hi,I am using LPUART and LPDMA on STM32U575. But I am getting Data Transfer Error.I have tried LPUART with GPDMA it works fine but LPUART with LPDMA giving Data Transfer Error.So I have two questions:1. Can we use LPUART & LPDMA together?2. What will be the cause of Data transfer error and how to configure LPDMA ?Can you please guide me on this?

I was going through the reference manual of STM32G4 series MCU. I saw information on using Op-Amps inside the STM32G4 as Inverting and Non-inverting amplifiers. There was no mention of them used as differential amplifiers, can they be used as differential amplifiers?

Heyho,how can I put a constant at the end of the STM32's used flash? (using: STM32CubeIDE)Not at a specific address (that's not a problem), but I'd like to have a constant always at the end of the used internal flash, independent of any other source code changes.I just find that there's some ASCII characters = "ASCII" (twice) and lots of 0x00 at the end of my H7 and F7 bin files - that from my sources or placed by CubeIDE? Thanks!

Moved from 'Feedback' forum. The 'Feedback' forum is not for product questions.Hello everyone,I’m currently working with the EVSPIN32G4 Rev.1 development board and the STM32 Motor Control SDK (MCSDK) using Motor Workbench, STM32CubeMX, and STM32CubeIDE.My goal is to control a brushless motor in closed loop using a quadrature encoder as the main speed/position feedback sensor.Setup:Software:Motor Control SDK: v6.3.2STM32CubeMX: v6.14.1STM32CubeIDE: v1.15.1Motor Pilot: v6.3.2Hardware:Board: EVSPIN32G4 Rev.1 (with STSPIN32G4 MCU)Motor: SM23165D (brushless) - ( datasheet link https://www.animatics.com/wp-content/uploads/2023/03/19_SM23165D.pdf )Encoder: 4000 counts/rev → 1000 PPR (Quadrature)Config 1: Sensorless + Encoder as AuxiliaryMain Sensor: Observer + PLL (sensorless)Auxiliary Sensor: Quadrature EncoderIn this configuration, the motor spins correctly and responds to speed commands (even if there's a ~500 RPM deviation).The speed measured by the encoder matches the

Hi we are looking for optical flow sensor and try to configure VD56G3 camera for this purpose which is connected to rasberry pi 4.I came across research artice which states that it does support optical flow using  MIPI CSI-2 interface.https://arxiv.org/pdf/2305.13087 However just looking at the user manual its not so clear how I can configure camera to output optical flow or displacement of  consecutive frames.Are there any additional materials I can look at or maybe software tools, SDKs that will give any examples of how to do it?

I'm a USB newbie and am trying to use the STM32F411CEU6 as a USB mic. I'm currently using FreeRTOS (cmsisV1) and the Cubemax USB library. My device currently enumerates normally, but when the host sends a URB_ISOCHRONOUS_IN request, my MCU won't handle it properly (according to SWD and serial port debugging, I found that the MCU won't even enter the OTG_FS_IRQHandler interrupt when the host sends this request). This has been bothering me for a long time. Here are my descriptors and some configuration code:__ALIGN_BEGIN static uint8_t USBD_AUDIO_CfgDesc[] __ALIGN_END = { /* Configuration Descriptor Head */ 0x09, // bLength 0x02, // bDescriptorType = CONFIGURATION 0x6D, 0x00, // wTotalLength = 109 bytes 0x02, // bNumInterfaces = 2 (Audio Control + Audio Streaming) 0x01, // bConfigurationValue 0x00, // iConfiguration 0x80, // bmAttributes: Bus powered 0x32, // bMaxPower: 100mA /* -------- Audio Control Interface (Interface 0) -------- */ 0x09, // bLength 0x04, // bDescriptorT

 I’m encountering an issue with XSPI1 in my application. I boot the application via XSPI2 in an LRUN configuration, and this part works perfectly. However, within the application, I need to use XSPI1 to write data to a different flash.During MX_XSPI1_Init(), the code crashes at this line:if (HAL_XSPIM_Config(&hxspi1, &sXspiManagerCfg, HAL_XSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK){Error_Handler();}I traced the crash to the exact line:IOM_cfg[0].IOPort = pCfg->IOPort;The initialization code for XSPI1 was generated using CubeMX. Interestingly, if I initialize XSPI1 in the boot project, everything works fine.I’ve already spent a week trying to solve this issue, but so far nothing has worked.I would really appreciate  suggestions to help solve my problem.

Hello,I am trying to set up  a UPD communication with a nucleo-H755ZI-Q board.Now I have the effect, that the lwip stack sends out an arp request for its own IP address.I double-checked the IP address and destination address to make sure they were correct. Does anyone have any idea, what could be causing this?Thank you.HiSt

Hello,I am trying to configure the secure memory in Secure Protection Bank 1 of options bytes section and for this I have followed the STM32 MOOC tutorial to understand the concept of using secure boot code. But I am facing issues as the base address for Bank 1 is expected be 0x08000000 as mentioned in STM32 G4 system memory protection document and also in tutorial whereas its showing as 0x00000000 Below is the screenshot from STMCube Programmer Option Byte settings from G474RE Board for your reference.I have also checked the similar settings with G071 board and I am able to get the base address as 0x08000000 as below and implement the secure boot code but unable to do in G474.Are there any other settings that I am missing out to configure in G474 to add the SEC_SIZE1 value?Can you please help me with this?Thanks

Hello,I have a question regarding the STM32WBA55G-DK1 board I have on hand.On my board, R42 is not populated. Could you please confirm whether R42 is not mounted by default?R42 is a 0 Ω resistor located on the control line of the general-purpose LED (LD3), and according to the schematic it appears to be mounted.I would appreciate it if someone could clarify this.Thank you in advance.

Hello, I am working with the LL_ATON library on STM32N6 and testing the LL_ARITHACC unit using the AFFINE operation, defined as: Output=A⋅X+B⋅Y+C.I ran several tests with a simple network model whose only purpose is X + Y.My expectation is:Case 1: A = 0, B = 0, C = 1→ Output is correctly constant 1 as expected.Case 2: A = 1, B = 0, C = 0→ Expected output = X, but the results are completely wrong and look like random values.Case 3: A = 0, B = 1, C = 0→ Expected output = Y, but again the results are incorrect and look randomSo, while the C_scalar works correctly, the usage of A_scalar and B_scalar does not produce the expected behavior.Questions:Is there any special configuration needed in the switch/stream setup for X and Y inputs when using AFFINE?The following screenshots are taken from the network.c file generated by the STEdgeAI compiler after compiling my simple X + Y tflite model. They show the configuration of the LL_ARITHACC unit for the AFFINE operation.Thanks.&n

I'm using the STM32F401RE in a new design and trying connect the USB CDC device interface to FreeRTOS_CLI. I modified its _write function to call CDC_Transmit_FS, but I don't see a received data callback where I can add a xTaskNotifyFromISRfor to send data to the CLI task.It looks like I call CDC_Receive_FS to get the data, but I need an interrupt to trigger the call to that function. Where can I hook in a callback function?
