Hi,I'm looking for SRAM memory for STM32H757xI and found thishttps://eu.mouser.com/ProductDetail/ISSI/IS66WVS4M8BLL-104NLI?qs=doiCPypUmgHfByEUFkOsAw%3D%3DDoes such kind or SRAM memory work with this MCU model?Thanks.

Hi, I have been trying to get acceleration data from an Adafruit LSM6DSO32 with the STM32 Nucleo board F446RE via i2c. I used the STMems_Standard_C_drivers  (GitHub - STMicroelectronics/lsm6dso32-pid at 308cf0e4de0db190c453f3e211b0c40990f1f39b) in order to set the IMU properly. I also use the STM32CubeIDE app to programme the MCU. Despite many efforts, the Nucleo board is not able to recognise the IMU (I checked that a test buffer that prints whether the device is recognised using the whoami register (please refer to the 7z folder attached)), though I double checked the slave address of the components and the connections (please see attached image (IMG_0605.jpg). Could you please help me solve that problem? You can find enclosed a copy of the STM32CubeIDE project. Best regards, Audric

Currently, I am working on a project that involves STU HF library, it works fine on the .net framework project. However. as we move on to the .net core project to branch out to other operating systems(Linux), the project could not read stuhfl.dll. My inspection is that the .net core is not compatible with the stuhfl.dll. Is there any other version of this dll that works on .Net core? Help is needed.

HI, We have an STM32L55CC with 256k flash on our board. Debugging was OK with a first version of 75Kb flash. A current test version tops at 204kB. And then the troubles began. Quite often the download in flash failed. I dind't find any soution on google and elsewhere. Seeing that I upgraded my CubeIDE and the driver of the ST/LINK V2.It works for some times and afterward stopped working. As I was working on the memory map I was messing all around modifying my map back and forth. Finally after having seen this https://community.st.com/t5/stm32-mcus-products/can-t-enter-into-debug-mode-after-writing-to-the-stm32l073/m-p/659060#M240303 I tried to mass-erase the flash from the STM32CubeProgrammer. After that I can reload the software and debug.But it is not stable. After a few downloads it breaks again, I mass-erase the flash and it restarts. Any ideas? Thanks in advance

Hi all,I config the SDIO & FATFS by cubeMx for my STM32F429BI board.When I config the SDIO to SDIO_BUS_WIDE_1B, everything is work well; Even the generated MX_SDIO_SD_Init() is NOT calling the HAL_SD_Init() function. (Why don't need HAL_SD_Init() , is this some mistake?) void MX_SDIO_SD_Init(void) { HAL_StatusTypeDef hal_sta; hsd.Instance = SDIO; hsd.Init.ClockEdge = SDIO_CLOCK_EDGE_RISING; hsd.Init.ClockBypass = SDIO_CLOCK_BYPASS_DISABLE; hsd.Init.ClockPowerSave = SDIO_CLOCK_POWER_SAVE_DISABLE; hsd.Init.BusWide = SDIO_BUS_WIDE_1B; hsd.Init.HardwareFlowControl = SDIO_HARDWARE_FLOW_CONTROL_DISABLE; hsd.Init.ClockDiv = 0; } However, when I change SDIO_BUS_WIDE_1B to SDIO_BUS_WIDE_4B, the operate to SD card is error.But when I change the code to below, the program works well again: void MX_SDIO_SD_Init(void) { HAL_StatusTypeDef hal_sta; hsd.Instance = SDIO; hsd.Init.ClockEdge = SDIO_CLOCK_EDGE_RISING; hsd.Init.ClockBypass = SDIO_CLOCK_BYPASS

I set up x-cube-mcsdk least ver.6.2.1 workbench with a combination of nucleo-h745zi(motor control board) and x-nucleo-ihm08m1(motor inverter board).The pin configuration is the default setting.Where should I connect x-nucleo-ihm08 to nucleo-h745zi?

Beside my Nucleo-H7S3L8 board, I have other boards where the MCU can do JTAG and have JTAG pin accessible, but neither STM32CubeProgrammer not OpenOCD and other programmers can detect/attach  via JTAG. SWD works works fine on these boardsHere the output of the Log window of STM32CubeProgrammer of two similar boards with  STM32L412KB chips with full JTAG connections, NJRST pin is left unconnected. First I connected the jtag-detectable board, than the undetectable:   15:44:20 : STM32CubeProgrammer API v2.16.0 | Linux-64Bits 15:44:26 : UR connection mode is defined with the HWrst reset mode 15:44:26 : ST-LINK SN : 51FF6D064888524933312587 15:44:26 : ST-LINK FW : V2J43S7 15:44:26 : Board : -- 15:44:26 : Voltage : 3,24V 15:44:26 : JTAG freq : 9000 KHz 15:44:26 : Connect mode: Under Reset 15:44:26 : Reset mode : Hardware reset 15:44:26 : Device ID : 0x464 15:44:26 : Revision ID : Rev A 15:44:26 : Debug in Low Power mode enabled. 15:44:26 : UPLOADING OPTI

most of the cameras in th market are with DVP and MIPI CSI interface, do DVP camera interface supports STM32H747 microcontroller, if so to which pins can we connect DVP to DCMI interface.

can you please explain me step by step process of uart communication in stm32h735g-dk 

Hi All, I am trying to generate variable frequency using TIM1 on STM32G070. I use TIM1 in output compare mode and PC8 as an output for channel 1. Pre-scaler is set to 0 and ARR to divider for whatever frequency I want. When checking registers I see CNT changing between 0 and ARR, as expected but nothing happens at the output. I tried to change PC8 directly to rule out electrical problem - it works fine.I need just to toggle the PC8, nothing else, but nothing happens... I went through many examples, but very few are relevant for stm32g0 using only CMSIS. Running out of ideas what could be wrong and looking at it for too long, so there is likely something I cannot see.If anyone has an idea where to look, that would be greatThanks // Enable clock for GPIOCRCC->IOPENR |= RCC_IOPENR_GPIOCEN;// Enable clock for TIM1RCC->APBENR2 |= RCC_APBENR2_TIM1EN; // Disable TIM1TIM1->CR1 &= ~TIM_CR1_CEN;// Configure TIM1 for Output Compare, toggle pinTIM1->SMCR &=

Hi,I was trying to disable Tzen in my nucleo-l55ze-q (stm32l55), but before disabling i forgot to flash toggle gpio programmer into board, and tried to set RDP to 55 and i clicked apply,From that moment it is not able to detect the STlink!..please give me any suggestions .Thanks and regardsTeju S H

Hi,I'm using stm32f103vet6 in my design, but due to the limit power budget, the MCU consumes much power(60mA per MCU , while I used 2 chips in my design), result in frequently triggering over current protection. Is there pin to pin compatible STM32L series part which could be utilized to replace the original one, so that I don't have to make hardware change?Thanks.

Hi,i'm always looking for the most efficient implementation of code in my STM controllers and was wondering which is the most efficient way to implement ADC reading from an external ADC chip trough SPI in an STM32G4 controller.The ADC (MCP3461/2/4) have a continious mode and set an interrupt line after each conversion. The 16 bit adc value is present in a buffer register to read trough SPI.I see these 3 choises:Using HAL_SPI_Receive_DMA, but as the ADC send 16 bits at a time i'm not sure this is the best solution. Each ADC conversion interrupt i need to start the DMA which fire a Transfer-Complete interrupt to read the actual value.Using HAL_SPI_Receive_IT, Each ADC conversion interrupt i need to start the interrupt driven SPI read which fire a Transfer-Complete interrupt to read the actual value. Just by reading the 16 bits each ADC conversion interrupt with the blocking HAL_SPI_Receive function as this goes super fast.i'm wondering is the overhead in the first 2 option makes it worth

Hello everyone, I'm a bit confused about using USB.I need to use the USB port both to create a CDC connection with a PC and to read/write data from USB flash drives.Initially, I wanted to create a project that could handle both HOST and DEVICE modes, but I see that I would have to generate two separate projects and then manually copy some libraries.I also tried the USB Dual Role configuration, but I don't understand its purpose as it doesn't generate anything related to USB.Then, I saw that I can create a configuration like USB HOST  with mode HOST SUPPORTING ALL CLASSES so I’m asking if with this mode I can do both things, and if you could point me to any examples of how to do this.I thank you in advance.

I would like to implement a BLE peripheral without using UTIL_SEQ.The sample project BLE_Peripheral_Lite seems to realize BLE functionality without using UTIL_SEQ, but when I add BLE functionality in STM32CubeMX, it is automatically set to use UTIL_SEQ. without using UTIL_SEQ. Is there any way to output source code by CubeMX without using UTIL_SEQ?Also, if UTIL_SEQ is not used, is it possible to use Timer Sever or Low power manager?Please tell us the other limitations of not using UTIL_SEQ.

I am using a Nucleo F401RE board to drive a PCM5102a PCM Audio Codec via I2S.My goal is to send data from a double buffer via DMA.Since I am only using the Audio Codec as an output, I configured my I2S as Half-Duplex Master in CubeMX.Now to my problem:In the generated I2S HAL driver stm32f4xx_hal_i2s_ex.c, there is no DMA Callback registered for Transmit Cplt or HalfCplt:I am calling HAL_I2SEx_TransmitReceive_DMA in main.c, to start the DMA cycle. everything works fine, except Callback invocation. Here is the corresponding snippet in the generated HAL_I2SEx_TransmitReceive_DMA, that prevents Tx Callbacks./* Set the I2S Rx DMA Half transfer complete callback */ hi2s->hdmarx->XferHalfCpltCallback = I2SEx_TxRxDMAHalfCplt; /* Set the I2S Rx DMA transfer complete callback */ hi2s->hdmarx->XferCpltCallback = I2SEx_TxRxDMACplt; /* Set the I2S Rx DMA error callback */ hi2s->hdmarx->XferErrorCallback = I2SEx_TxRxDMAError; /* Set the I2S Tx DMA Half transfer complete callbac

Hello all, I have made a GUI with some circles that show as a LED. When the LED must be turned on the color of the circle shall be green and LED is OFF then the color must be changed to gray. So when I change the screen to another and back again, the color changes to a default value. As I understand I need to save the status to the Presenter and then to the model afterward I should get the status from the model and then the presenter. So now I want to know how to save the circle's color when leaving the screen. here is the screen shot for screenview:  

I'm using TouchGfx 4.21.3 for designing LCD screens for my project with ST Microcontroller. I have a requirement to have 4000 of value to use for scroll list and each element in scroll list is container. Can I make scroll list with 4000 items in it (scrollList1.setNumberOfItems(4000);)? How much is the maximum value that scroll list can expand?

Hello All, I'm currently working with the STM32 H747-DISCO board, but I'm encountering some difficulties in interfacing both the B-CAMS-OMV Camera Module and the LCD. After flashing the camera module, it successfully captures images, and I've also flashed the LCD, which displays the Embedded Wizard GUI. However, only one of them seems to be working at a time. Could you please advise if there are any steps I might be missing? Additionally, I'm seeking guidance on how to interface both the camera and LCD simultaneously. If there are any resources available, I'd appreciate it if you could share them with me.

I'm working with the STM32F407G-DISC1 development board and I would like to generate a square wave on PB14 (TIM8_CH2N). I'm able to successfully toggle PB14 using "bit-banging" and I'm able to successfully generate square waves PC6 (TIM8_CH1) and PC8 (TIM8_CH3). However, no matter what I do, I can't make TIM8 output anything on PB14 (TIM8_CH2N). Does anybody know what I'm doing wrong (please see attached screenshot)? Please note that I can't use any other timer/pin instead.

I have successfully built the DRP1M1_DRP Dual-Role USB-C project targeting the NUCLEO-G474RE (supplied with X-CUBE-TCPP v4.4.0). The first time I tried RUN, I had to update the ST-LINK software on the NUCLEO board (it's brand new), but having done that when I try again I get the attached error saying:Error finishing flash operation Please see attached, any ideas please?
