Solved

Searching through the forum it seems like there are tens of posts regarding this topic. I read many of them, but I struggle to find a solution that applies to me.First of, I use an STM32H743VIT.My goal: Use ADC1 and ADC2, one channel each. The two ADCs should be tied together. The whole conversion should be triggered by TIM4 update event and the data should be moved via DMA.What works: If I just use TIM4 and two DMA streams that move the data for each ADC individually, it works. As soon as I try to use the dual mode, it does nothing.When I'm in dual mode I have confirmed that the timer is still running. TIM4->CNT is changing. I've spent almost two hours with the debugger in the SFR and checked the registers. I'm not sure if I'm close to the issue, but there is something that seems suspicious based on the research I did: DMA1->S0NDTR->NDT does not change, indicating that the DMA stream does nothing. However ADC1->CR->ADSTART is at 0x1, indicating that it tries to do somet

Hello AllI'm working in STMCubeIDE 2.0.0 Windows.I have downloaded STM32Cube_FW_F4_V1.28.0 package and saved it here: C:\Users\marin\STM32Cube\Repository\STM32Cube_FW_F4_V1.28.0I want to use an example and build a project from the example.This LCD example: C:\Users\marin\STM32Cube\Repository\STM32Cube_FW_F4_V1.28.0\Projects\STM32F429I-Discovery\Applications\Display\LTDC_Paint.I don't want to change the original example code, I want to put the example into a new folder and do my changes there.I saw using "Copy to workspace" when importing is a mess and don't compile:  No rule to make target 'C:/Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_core.c' Do I have to copy the whole directory to a new location?  C:\Users\marin\STM32Cube\Repository\STM32Cube_FW_F4_V1.28.0\Projects\STM32F429I-Discovery\Applications\Display\LTDC_Paint. Please show me a way to copy the example code (Only LTDC_Paint project) to a new location and successfully compile. Ma

As my project has morphed I have started from a STM32F103, moved up to a G431, then a F446.With a few #defines and tweaks I have a shared main app code base with identical project structures for each of the processor types (that makes it easy to switch between MCU boards as when whilst doing code tests).All theseSTM32CubeIDE projects have Runtime library = Reduced C, and "do not use default libraries" is ticked. All build fine.All used CubeMX to generate the appropriate sources etc.., all have 99.9% identical CubeIDE project structures.As a stepping stone to a STM32F723 I am bodging up a port to an STM32H723, but so far have been unsuccessful in getting it to link. It seems to be having a problem related to the c library area.(.text._getpid_r+0x0): undefined reference to `_getpid'/home/main/.eclipse/com.st.stm32cube.ide.mcu.rcp.product_2.0.0_1934254364_linux_gtk_x86_64/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.14.3.rel1.linux64_1.0.0.202510151430/tools/bin/../l

Hi We have a old PCBA design with a TDK IMU sensor. When I look at the footprint and pinout it seems like it actually drop-in-replaceable and we should need no new PCBA design, only change the BOM list and replace the TDK sensor with LSM6DSV320XBut the LSM6DSV320X datasheet says that pin 10 and pin 11:Leave pin electrically unconnected and soldered to PCB.But in our design thay are connected to GND signal ground.What would happen if we replace it, will the LSM6DSV320X not work if the pins 10 and 11 are grounded? krrØystein

CubeProgrammer doesn't work with OpenJFX 11, but OpenJFX 8 cannot handle HiDPI screen, which makes Cube Programmer almost illegible.Since you were able to release several new versions in the past months, could you please also update to Java 11, or fix the HiDPI issues yourself?

Isn't TrustZone something which started to be only since Cortex-M33?JW

Where to start...I have mave made a bootloader (done this before), which is placed in the low end of the flash memory. The application is in the subsequent flash.My board has a USB port and a DIP switch for forcing the BOOT input pin high. When I flip the DIP switch on, and power the board, I can connect STM32CubeProgrammer to the internal DFU bootloader via the USB port. I can also upload my application through the USB port. But when I try to upload my own bootloader, it fails. This is the output from STM32CubeProgrammer:However, if I connect an ST-LINK programmer to the board, I can upload the very same file with no issues. Output from STM32CubeProgrammer:Clearly, something starts to go wrong at "Not flash Memory: No erase done"Just now, I upgraded STM32CubeProgrammer to the latest version (2.21.0), but this made no difference.But why does it work with the ST-LINK programmer, and not through the USB port? And why can I upload the application through the USB port, but not the bootload

I am new to ThreadX. I have had experience with FreeRTOS generated with CubeMX.However, I have been starting over repeatedly with CubeMX. Just trying to create a base project with Nucleo-F767Zi.I need to find some documentation for starting this process. I am missing something.Thanks,Greg

 I've been trying for days to find a MIPI CSI-2 thermal camera for use with the STM32N6570-dk.I even looked in the STM store.I even found a company that seems to have one, but their communication system doesn't accept any of my emails.Does anyone have any suggestions to help me?Thank you.

Hi,I haven’t used SWO functionality before, but I now need it to stream real-time data.I’m using VS Code with the STM32CubeIDE extension, but I haven’t found any options to configure and display real-time data (via SWO) in a VS Code window. How can this be done?If this isn’t possible in VS Code, what alternatives would you recommend? Ideally, I’d like to output both text messages and real-time numeric data, with the data automatically plotted on a chart. What is the best way to achieve this?Thank you

Using STM32TRUSTEE-SM framework, the non-secure application is built by the project.py script which in turn callsSTM32TrustedPackageCreator_CLI.exe -pb SM_Code_Image_bin.xmlto generate the application .bin file in MCUboot format.The xml file has <Param> <Name>Security Counter</Name> <Value>auto</Value> <Type>Data</Type> <Command>-s</Command> <Hidden>1</Hidden> <Default>auto</Default> </Param>It is my understanding that with this setting, an incrementing counter should be placed in the image header's ih_ver.iv_build_num field. But this field stays 0 no matter what I put under <Value>, auto or direct number.There is a command "-s" which according to the documentation would be passed on to the imgtool executable, which, however, is described as thisand therefore would have nothing to do with any counter.Could anybody shed some light on it, please? I am using the latest version 2.20.

Hi, I am struggling with TIM2 to restart its CNT from zero without using hal. I am using nucleo-f446 TIM2 clock frequency is 21MHz (no prescaler, 1/4clock division) CNT set for upcounting. I want to use TIM2 to write a simple us_delay function, so I need to restart its CNT  whenever us_delay is called. No matter what I do, I can't make it work, here is the code I am using: TMR2_Start = 1; //start counter TMR2_URS = 1; //Only counter overflow/underflow sets UIF bit TMR2_UDIS = 1; //disable update event generation TIM2->ARR = 2100; //set 100us delay (tim2 clock frequency = 21MHz) TMR2_UDIS = 0; //enable update event generation TMR2_UG = 0x1; //restart counter while (TMR2_UIF == 0){ //wait until TMR2_UIF is set } I put a breakpoint right before while loop is executed, I can see that CNT is enabled, URS set, delay value loaded to ARR. However CNT is not reset to zero, it has a random value, sometimes as high as 0x1A9C, plus the UIF and the Capture/Compare flags are all set for unkn

Heyho, just found that the N6 has gigabit ethernet - which might help me staying away from the monstrous MPUs... :D Is there kinda compatibility list between the STM32 families for the peripherals? ethernet interface, surely different HW concerning GbE vs 100M, but maybe the registers / descriptors work basically the same? CANFD and the SAIs? OCTOSPI / XSPI with memory-mapped HyperRam?  the (partly) more simple peripherals like ADC, timers, UART? Merci!  

Hi, I'm using STM32F407 TIM1 channel 1 to measure the frequency of a square wave. The result is not accurate. For example, when input frequency is 1000.0Hz, the result is around 1006Hz. Input frequency has been verified by an oscilloscope, with probe attaching directly to STM32 pin. My ioc configuration:1. APB2 peripheral clock frequency is 42MHz, APB2 timer clock frequency is 84MHz. (in the datasheet, TIM1 connects to APB2)2. Pin PE9 is configured as TIM1_CH13. TIM1_CH1 uses Input Capture Direct mode4. Prescaler=1 (so TIM1 frequency=84/(1+1)=42MHz)5. Counter mode is Up, Counter Period is 65535. auto-reload preload is Enable6. A DMA connects to TIM1. DMA Request is TIM1_CH1 to capture TIM1->CCR1's value My code:#include "main.h" #include <assert.h> #include <stdint.h> #include <stdlib.h> TIM_HandleTypeDef htim1; DMA_HandleTypeDef hdma_tim1_ch1; #define ARRAY_LEN(a) (sizeof(a) / sizeof(a[0])) #define TIM_FREQ 42000000 // TIM1 frequency is 42MHz // g_timD

We have a board with an STM32H7S3, using STiROT and OEMuROT to run our own application. The application runs in place from external flash, and uses external RAM for data.The process has proven extremely challenging, but we have been able to get the application to run...up to the point where it needs to initialise a peripheral which uses a PLL-dependent clock.OEMuROT does some clock initialisation, but we need to change some of those settings, including turning on additional PLLs.I've tried adding clock setup code to the app (originally generated by CubeMX), but it fails because you can’t change PLL settings while they’re running. So I added a call to the HAL function to reset the clocks first – but that also doesn’t work because we’re running from the external flash at this point, which relies on a PLL!I then tried moving the clock setup code into the bootloader – in the code which runs at the end of proceedings, or at the start – but they also failed.This code has to run from internal

I've interfaced the VL53L4CD with ESP32-S3, but I'm unable to get accurate ranging values below 70mm.I'm using the ESP32-S3 with Arduino IDE.How can I resolve this issue ?#include <Wire.h> #include "vl53l4cd_class.h" #define SDA_PIN 8 #define SCL_PIN 9 VL53L4CD sensor(&Wire, -1); // -1 = XSHUT not used void setup() { Serial.begin(115200); delay(1000); Wire.begin(SDA_PIN, SCL_PIN); Wire.setClock(400000); Serial.println("VL53L4CD Init..."); if (sensor.begin() != 0) { Serial.println("VL53L4CD not detected"); while (1); } Serial.println("VL53L4CD detected"); sensor.VL53L4CD_SetRangeTiming(50, 0); // 50ms timing sensor.VL53L4CD_StartRanging(); } void loop() { uint8_t dataReady = 0; VL53L4CD_Result_t results; sensor.VL53L4CD_CheckForDataReady(&dataReady); if (dataReady) { sensor.VL53L4CD_GetResult(&results); sensor.VL53L4CD_ClearInterrupt(); Serial.print("Distance: "); Serial.print(results.distance_mm); Serial.println(" mm"); } delay(20);

Dear Community,I have a general question. I wanted to use C++ classes in SPC5 Studio to get a cleaner project structure.For this, I changed main.c to main.cpp and included the C headers using extern "C". I also enabled the C++ linker in the Platform Component RLA.The project builds without any issues, but the parsing errors in the editor are extremely annoying. A lot of the code is marked in red even though it compiles fine.Does anyone know what setting I need to adjust to get rid of all these unresolved reference errors in the parser (i presume...)?Kind regards,TKorn

Hello, i just wanna take a snapshot by STM32N6570-DK with IMX335. I am using SnapshotDecimation as my reference. after reviewing the code. i wonder why AXI RAM3/4 and RIF are necessary for this project i saw it in 'HAL_DCMIPP_MspInit' function, but i didnt found anything about AXI RAM in other parts of the code.anyone can explain why does axiram necessary for this project?void HAL_DCMIPP_MspInit(DCMIPP_HandleTypeDef* hdcmipp) { RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0}; RAMCFG_HandleTypeDef hramcfg = {0}; RIMC_MasterConfig_t RIMC_master = {0}; if(hdcmipp->Instance==DCMIPP) { /* USER CODE BEGIN DCMIPP_MspInit 0 */ /*** Enable peripheral clock ***/ /* Enable DCMIPP clock */ __HAL_RCC_DCMIPP_CLK_ENABLE(); __HAL_RCC_DCMIPP_FORCE_RESET(); __HAL_RCC_DCMIPP_RELEASE_RESET(); /*** Configure the NVIC for DCMIPP ***/ /* NVIC configuration for DCMIPP transfer complete interrupt */ HAL_NVIC_SetPriority(DCMIPP_IRQn, 0x07, 0); HAL_NVIC_EnableIRQ(DCMIPP_IRQn

i have been trying to find ways of converting my stm32f103 board to stlink for a personal project , i  have found out i need to flash the st link firmware onto this chip but i am not really able to understand how to flash this on the board , if someone has any way to do this it would a huge help , i cant really do anything else as i have already printed a pcb for this purpose so if any one has any way to flash the stlink firmware onto the f103 chip it would be huge help  ? the board is stm32f103CBT6 (64KB FLASH + 20KB RAM ) 

I want to know what computer vision is and what are its real world applications. 

The X-CUBE-AZRTOS-H7RS middleware is missing the setting to change the USBX System Stack Size which in turn means that the USBX_MEMORY_STACK_SIZE define in the app_usbx.h file can not be changed from its default of 1024. And because the define is not in a USER CODE section, any manual change will be overridden when re-generating code in CubeMX.Here is an example when using USBX host stack, but it's the same for the device stack.STM32H7RSxx:STM32H7A3ZIT:  

Hello,I'm having trouble deploying the middleware for the X-NUCLEO-NFC12A1 demo board.I have an x-NUCLEO-NFC12A1 and a NUCLEO-WBA65RI.I connected the two boards together, wired the pins correctly, and tried to use the X-CUBE-NFC12 middleware package. However, when I generate the project, it only includes the ST25R500 driver under Drivers/BSP/Components/.How can I get a proper starting point to develop with the ST25R300? Is there a specific package or example project available for it?My goal is simple: I want to use it to enable and operate a WLC with a PTX30W.Thanks a lot for your help,Yvan

Hi everyone,I'm currently porting the App of STM32U5 SBSFU example to CubeMX and "smooth" is not the word I would use to describe the process.Namely, the SBSFU example includes Bootloader, Loader and App projects with memory map being in separate centralized header files included by all these projects. These files (region_defs and flash_layout) are not fully polished (some bugginess and inconsistencies) but they do ease the memory management a lot by using defines and not hardcoding; these defines are then used in projects' linker files in order to define memory regions.In contrast, CubeMX just provides a UI representation of the memory space where users can input all the memory bounds, be it flash or RAM. The trouble is, we can only enter numbers and not constants, so generated code is full of hardcoded address bounds.This does not play well with SBSFU Example - since these address bounds are not only used in LD files, but rather for defining FLASH areas, SAU regions etc etc, it is an

Hi, I am trying to establish CAN communication between three different MCUs: NUCLEO-H723ZG, NUCLEO-H755ZIQ, and NUCLEO-G474RE. However, I am unable to successfully communicate between the boards, even though the same baud rate has been configured on all MCUs. I have also connected an external CAN transceiver to each board for proper CAN bus operation. On the NUCLEO-G474RE, I have enabled UART4 to send command data, using the following pins: PC11 – UART4_RX PC10 – UART4_TX Clock Frequency [SYSCLK] & Baud Rate [CAN]: 1. NUCLEO-H723ZG: 550 MHz     Baud Rate: 500000 Bit/s     2. NUCLEO-H755ZIQ: 480 MHz     Baud Rate: 500000 Bit/s     3. NUCLEO-G474RE: 170 MHz     Baud Rate: 500000 Bit/s    

Probably this is trivial, but I just cannot find it.How to deploy image using CubeIDE for VS Code without debugging?How to properly configure Build+Deploy only (no debug) task in tasks.json file?How to configure Build+Deploy with debug task?Should I use cube cli for that or there is some easier way?
