Use SPI with MCU above.  Withspi_transmit(0x55);andvoid spi_transmit(uint8_t tx_data) { SPI1->DR= tx_data; while (!(SPI1->SR & SPI_SR_TXE)); }I have 16 SPI clocks. Init was: hspi1.Init.DataSize = SPI_DATASIZE_8BIT; Data on MOSI showing on the first 8 clocks, MOSI on remaining 8 clocks is zero.While using HAL (same init):pdat= 0x55; HAL_SPI_Transmit(&hspi1, (const uint8_t *)&pdat, 1, 100);I have, as expected, 8 SPI clocks.Any Suggestions? Thanks!

I am working on a project using the STM32U5G9ZJT6Q MCU, where I am trying to receive data from an 8-bit DCMI interface using GPDMA in circular mode or normal mode. The data is being captured from an 8-bit parallel bus, and I am using GPDMA to transfer this data into memory. However, I am facing issues with the DMA interrupt not triggering and the data not being received properly.I have configured the DMA in circular mode and linked it to the DCMI, but it seems that the DMA transfer is not functioning as expected. I’ve tried various configurations, but I am still unable to get it working.If anyone has worked on a similar setup using the STM32U5G9ZJT6Q and has successfully received data from DCMI using GPDMA in circular mode or normal, I would greatly appreciate it if you could share your code or any insights on how to properly configure and troubleshoot this.

Hello, I downloaded an example "Nx_SNTP_Client", and all the include files are hidden in the file tree (left pane)1-  Where is the setting to show these files?  (Why is this even an option)?2- Why does the Search/Find not work with these hidden files? I looked at: https://community.st.com/t5/stm32cubeide-mcus/cubeide-imported-example-file-structure-does-not-show-header/m-p/75355#M1515 with a similar question, and i see the "outline" tab, but how does that fix the search problem?  What am I missing?thanksMatthew

I've been working with the Nucleo STM32H533 and came across a documentation issue. EXTICR1 and EXTICR4 are shown as having the same address on pages 18.6.15 and 18.6.18 of the reference manual. Additionally, in the Special Function Register tab in STM32CubeIDE, they are also labeled incorrectly. However, they are correctly labeled in the register map section of the reference manual.This threw me off for a while—I wasn’t seeing any changes in the EXTICR4 register while debugging. When I manually modified the bits in EXTICR4, the changes were mirrored in EXTICR1. It wasn’t until I checked the memory browser that I realized the register was being set correctly when using the register map address and noticed the inconsistencies elsewhere. 

Hi,I am installing VS Code with the STM32 extension. In the settings I need to provide a path to the MX executable. But it is not anywhere on the C drive (where everything else ST is installed).I remember I installed it with/through CubeIDE, does it mean it is not an .EXE on the drive? And so perhaps I also need to install the CubeMX as standalone?Thank you

Hi everyone: I am working on a project with VL53L8CX Time-of-Flight sensor from Pololu. I integrated it with NUCLEO-H755ZI-Q board over SPI interface based on the example and driver provided in the STMicro en.STSW-IMG040 software package. I configured the SPI3 (MCLK, MISO, and MOSI) on the CN7 to communicate with the sensor. I also have PA4 for SPI3_NSS and PC7 for /PLn signal. The project compiled successfully. However, I believe I am not able to read the registers properly. The firmware reads the "device_id" and "revision_id" from the sensor in the vl53l8cx_is_alive() to determine if the sensor exists. The return values different every time I tried to read. I was able to capture the protocols on the scope, and confirmed the reading values are match with the data shown on the scope. The following scope capture shows the communication:1. Sending 0x00 to address 0x7fff. The yellow signal is for the MCLK, blue for MOSI, purple for MISO, and green for /CS.2. Receiving 0x0 from addres

Hi,   I'm working on an STM32U595 and there is a code generation problem in the function `void PWR_S3WU_IRQHandler(void)` where when you have multiple wake up pins and S3WU interrupt enabled : /* USER CODE END PWR_S3WU_IRQn 0 */ HAL_PWREx_S3WU_IRQHandler(PWR_WAKEUP_PIN2 || PWR_WAKEUP_PIN5 || PWR_WAKEUP_PIN6); /* USER CODE BEGIN PWR_S3WU_IRQn 1 */   But the generated code should be: /* USER CODE END PWR_S3WU_IRQn 0 */ HAL_PWREx_S3WU_IRQHandler(PWR_WAKEUP_PIN2 | PWR_WAKEUP_PIN5 | PWR_WAKEUP_PIN6); /* USER CODE BEGIN PWR_S3WU_IRQn 1 */   This creates a big problem because as soon as you define several wake up pins in stop mode 3, it no longer works.   Best regards, Steven

Hello,I am trying program the flash memory on an STM32f401RE.After successfully programming sector 7 I cannot flash a new application to my board, instead I am met with :Error: ST-LINK error (DEV_TARGET_NOT_HALTED) I can flash new code after a mass erase with cube programmer but this shouldn't be necessary. Here is the code I am using. FLASH_EraseInitTypeDef erase_op; erase_op.TypeErase = FLASH_TYPEERASE_SECTORS; erase_op.Sector = FLASH_SECTOR_7; erase_op.NbSectors = 1; erase_op.VoltageRange = FLASH_VOLTAGE_RANGE_3; uint32_t err; if(HAL_FLASH_Unlock() == HAL_OK) printf("Unlocked flash!\r\n"); if(HAL_FLASHEx_Erase(&erase_op, &err) == HAL_OK) printf("Erased memory!\r\n"); char str[] = "Hell"; uint64_t data = 0; memcpy(&data, str, 4); if(HAL_FLASH_Program(FLASH_TYPEPROGRAM_WORD, 0x08060000, data) == HAL_OK) printf("Flash programming was successful!\r\n"); printf("Flash error : %lu\r\n", HAL_FLASH_GetError()); if(HAL_FLASH_Lock() == HAL_OK)

Hello,I’m experiencing issues while programming the RVT101HVSFWCA0 Riverdi display. Specifically, I encounter errors when uploading my project using TouchGFX and STM32CubeIDE.I would greatly appreciate your assistance in resolving this matter. I’ve attached a screenshot showing the errors and my current connection setup.

Hello,I am looking at the STEVAL-ISB027V1 dev board. I see that it is obsolete. That is fine, I am more interested in understanding if this design could be implemented on 6x independent channels of Tx coils. I want to be able to independently control 6x copies of this circuit but use a single micro. What would you recommend for an application like this?

Hello, I am trying to implement a zigbee network using stm32wb55 custom board. I use STM32Cube_FW_WB_V1.21.0 zigbee examples. Everything works perfectly, butI want to change the client/router 64 bit IEEE address, but I can't find where it is set or hard coded in the code.I have to change it because end devices must have unique IEEE addresses.

I am using a STM32N6570-DK board and I can't understand how to configurate the FSBL, Application, and the External memory stuff in Cubemx. Can anyone describe how to use and configurate these three options?

"I followed along with this video, but I have some questions. How can I correctly retrieve the ADC array values via UART communication? And why is the UART value coming out as garbage in this video?"https://www.youtube.com/watch?v=_hX6pN2jgYMhttps://rristm.github.io/tomas_materials_v2/RRISTM/stm32u5_workshop/master/2_gpdma_handson_list_mode_mx.md/17 I think it's a clock issue. How can I fix this?

Hi,I want to use CLion for development, which requires CMake, and I've been struggling with integrating the X-CUBE-MATTER package in it.Globbing all files withfile(GLOB_RECURSE src_files "Middlewares/*.c" "Middlewares/*.cpp" "Drivers/*.c" "Drivers/*.cpp")produces a binary significantly larger than FLASH and still fails to compile because it includes various examples and templates.Another option I thought of is manually adding all the necessary files, however that seems like a herculean task.Is there an easier way to go on about this (perhaps ST is already working on it)? Thank you for your reply.

I am a student in embedded systems. I have a final project with the stm32h747i-disco card. I want to configure the touch screen to make a graphic interface.

Hi All,I've been trying to bring up a custom external loader for well over a week and I'm just not getting anywhere.My processor is an STM32L496VGT6 and its connected via quadSPI to an MT25QL128A 16MB external flash memory. I'm running the clock at 80MHz, and my QUADSPI is setup like this (both in my custom loader, and in the application code I'm developing):Following mostly along with the "External QSPI loader how to" (from here External QSPI loader how to - 05 – QSPI driver coding - YouTube), and utilizing the files in the contrib branch of the stm external loader github repository (GitHub - STMicroelectronics/stm32-external-loader at contrib), I've put together what seems like a working driver for the MT25QL128. I got there by starting with the quadspi.h/c files in the stm32-custom-loader/QSPI_Drivers/MT25QL512/ folder, and then modifying them using the micro datasheet for the part to swap different commands where necessary. I pulled in test code from the main.c file in st

I am using a Nuclro-303RE to develop a USB Virtual Com port, and I am running into an issue that I cannot seem to resolve.  Just to verify things, I did put some really simple code in the flash the green indicator on the Nucleo board.I have it connected to a custom board that runs the USB lines out to a USB connector.It is powered externally with 5V to VIN. Jumper set for E5V. The power indicator on the Nucleo is on, and the 3.3V is running.I am able to run it with the debugger tool, however, it will not run with just the USB and the 5V in.When I plug in to the USB on the ST-Link board, it starts to run, i.e. the green LED will blink, and the USB will enumerate for the USB virtual com port.I did add an 8MHz oscillator @ X3 and associated parts.I do have a pull up on the USB line.        

Hi everyone!I'm trying to validate an ONNX model on my STM32H747I-DISCO board, but I'm running into issues.I've successfully generated the project and flashed it onto the board. The validation process does run (using random inputs), but the final metrics I'm getting are all NaN.I'm using the FP32 version of the model (not quantized), and when I run the same validation on desktop, the metrics are almost perfect — so the model itself seems fine.I've tried enabling the --classifier option, but it didn't make any difference. I also attempted using --no-onnx-io-transpose, but got the following error: stedgeai: error: unrecognized arguments: --no-onnx-io-transpose Could this be an issue with my model, the CubeIDE project or am I missing something in the X-CUBE-AI configuration ? I've also noticed that there is a note in the csv file with the inputs:# Note: w/o datanumber of item by sample is exceeded: 4096 > 512Is this issue compromising the classification ?Thanks in advanc

I'm trying to run a sample PWR_DEEPSTOP_RTC from PWR_DEEPSTOP_RTC, but I'm facing some problems.The code works correctly, the UC enters deepstop mode and returns to run mode, but when I try to measure the current in PJ2 as described in item 7.1.4 of UM3345, I get 90uA when in deepstop mode and not around 1uA as the datasheet says. (RTC wakeUP, LSi 32k).I follow this example recipe:/* The following Wakeup sequence is highly recommended before each entry into Deepstop modeespecially when using more than one wakeup source, this is to not miss any wakeup event.- Disable all used wakeup sources,- Clear all related wakeup flags,- Re-enable all used wakeup sources,- Enter Deepstop mode.*/Is there anything I missed or didn't understand?

Hi   I have a a stm32L433 48 pin processor and trying to get it into low power. I am using the STLink-V3PWR module with stm32Cube Monitor Power module.   First of all I placed a known value resistor across the STLink-V3PWR to make sure it is reading the correct value, then tried the following: 1. I am using a MIC5219-3.3YM5-TR from the input with the STLink-V3PWR set to 3.6v.  And on its own it draws 85uA.2. I then added all the resistors and capacitors needed and it measured 96uA.3. I added the STM32L433 and programmed it to first run for approx 5 seconds in normal mode (16MHz), then drop into standby mode. On the output you can see it drop quite a bit, but the lowest current is approx 650uA (far too much current) as you can see on the graph below. My code is below after 5 seconds of normal operation. I tried HAL_PWREx_EnterSHUTDOWNMode(); without Putting the Ram in Retention, but still the same,void EnterLowPower() { RCC->APB1RSTR1 |= RCC_APB1RS
