Hi,I have problem (OVERRUN flag) with data transfer from DCMI to external SDRAM.I have STM32H753 which in AN5020 has architecture like this:(Application note, Digital camera interface (DCMI) for STM32 MCUs)So it has connection between DCMI and FMC via DMA1/2 and D2-D1-bridge.Great, but ...when I send frame 320x240@RGB888 from DCMI to SDRAM, I get in HAL_DCMI_GetError value 0x41 (HAL_DCMI_ERROR_DMA | HAL_DCMI_ERROR_OVR) and in HAL_DMA_GetError valueo 0x00 (HAL_DMA_ERROR_NONE).Configuration for DCMI and DMA:hdcmi.Instance = DCMI; hdcmi.Init.SynchroMode = DCMI_SYNCHRO_HARDWARE; hdcmi.Init.PCKPolarity = DCMI_PCKPOLARITY_RISING; hdcmi.Init.VSPolarity = DCMI_VSPOLARITY_HIGH; hdcmi.Init.HSPolarity = DCMI_HSPOLARITY_LOW; hdcmi.Init.CaptureRate = DCMI_CR_ALL_FRAME; hdcmi.Init.ExtendedDataMode = DCMI_EXTEND_DATA_8B; hdcmi.Init.JPEGMode = DCMI_JPEG_DISABLE; hdcmi.Init.ByteSelectMode = DCMI_BSM_ALL; hdcmi.Init.ByteSelectStart = DCMI_OEBS_ODD; hdcmi.Init.LineSelectMode = DCMI_LSM_ALL; hdcmi.Init.Li

I would like to increase no-response time by a few ms instead of 64/fc (4.72us) or 4096/fc(302.08us?), say 100ms(milliseconds). What should be the values in 0Fh, 10h and 11h registers.? I see bit4 in 0Fh register mentions time configuration in milliseconds configuration but don't how to use.Host uses rfal API.Thank you for your support!Thanks,Veera

Hi,Master:​​Platform: STM32F301K8UCPU clock frequency：72M​As shown in the figure, the original analog video signal (PA7 pin) is compared with DAC1_CH1 through a comparator, and a pulse sequence with a slightly changed duty cycle and period is output. ).my question:How to control PA8 (or PA9 / PA10) to output a pulse sequence that is inverse to this pulse sequence, but the phase shift should not exceed 0.25us? I now capture the input of PA3 and control the PWM output of PA8 in its interrupt, resulting in the output waveform always being slower than PA2 (much greater than 0.25us).Thank you very much.​

Hello,I am trying to set up CAN communication on my F042K6 using the HAL library. I have followed the stm guide (attached). I got most of the functionality working, however if i try to use the Rx interrupt using "void HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef*hcan)" the MCU gets stuck in this interrupt when it receives a message. I do not know what i am doing wrong and why I cannot leave the interrupt. I think it might have something to do with the NVIC interrupt priorities maybe? If someone could help me out it would be greatly appreciated. Please see attached my code, NVIC settings and the guide i followed.Thank you:)

Hello everyone,I'm working on the ST B-G431B-ESC1 board and I don't understand the function of the pin GPIO_BEMF from the Back-EMF detection. This pin is in common with the others motor phase. Can you explain the function of this pin please ?The full schematics is available here : https://www.st.com/resource/en/user_manual/dm00564746-electronic-speed-controller-discovery-kit-for-drones-with-stm32g431cb-stmicroelectronics.pdfThank you.

Hello, I am trying to use the LSM to detect taps . I use the default configuration which suggested in the application notes : 1. Write 60h to CTRL1_XL // Turn on the accelerometer   // ODR_XL = 417 Hz, FS_XL = ±2 g   2. Write 0Eh to TAP_CFG0 // Enable tap detection on X, Y, Z-axis   3. Write 0Ch to TAP_CFG1 // Set X-axis threshold and axes priority   4. Write 8Ch to TAP_CFG2 // Set Y-axis threshold and enable interrupt   5. Write 0Ch to TAP_THS_6D // Set Z-axis threshold   6. Write 7Fh to INT_DUR2 // Set Duration, Quiet and Shock time windows   7. Write 80h to WAKE_UP_THS // Single-tap and double-tap enabled (SINGLE_DOUBLE_TAP = 1)   8. Write 08h to MD1_CFG // Double-tap interrupt driven to INT1 pin With this configuration i am able to get interrupts. My problem starts when i try to check the cause of the interrupt by reading TAP_SRC or ALL_INT_SRC. When i read ALL_INT_SRC register i see that the cause of the interrupt was Wake-up event(W

I am trying to install autodevkit plugin using install new software option from help but some features are not getting installed.I am getting the following error:Missing requirement: Autodevkit feature Group 1.1.1.20200327200248 (com.st.tools.autodevkit.feature.group.feature.group 1.1.1.20200327200248) requires 'com.st.spc5.components.spc5rla.usbtypec.full.feature.feature.group 1.3.2' but it could not be foundI think this error is linked to the missing feature/improper installation of autodevkit.Please guide .

Hello,I'm using a STM32L072CB with STOP mode and in section 32.9.3 in the user manual I stumbled over following information:"When exiting from Stop mode, the clock configuration is identical to theone after RESET. Consequently, the software must reprogram the clock controller to enable the PLL, the Xtal, etc."I'm using the MSI at range 6 (default is 5) and the LSI is ON. Additionally there are changes for example in RCC_CCIPR and RCC_CSR. And also checked following question:https://community.st.com/s/question/0D50X00009q2xHv/stm32f0-reconfigure-clocks-after-exiting-stop-modehttps://community.st.com/s/question/0D50X00009XkWtNSAV/what-to-configure-after-stopmode-wakeup1. Question: What is the meaning of RESET? The reset values in the register map in section 7.3.22? 2. Question: Are only the registers of the RCC affected or also the peripherals (e.g. LPTIMER?)3. Question: Basically I "only" need to reconfigure the RCC registers (section 7.3 in user manual) again after leaving STOP mode?

Hello,I'm using STMCubeIDE, with firmware version: STM32Cube FW_F4 V1.25.0I am trying to implement a USB virtual COM port. My code is working on the STM32F4 discovery board. I then created a new project for the STM32F411CEU6 "Black Pill", but the USB device will not enumerate. Error message in windows is "Device Descriptor Request Failed"For the project, I select "Device Only" for USB_OTG_FS, and in the USB_DEVICE middleware, I select "Communication Device Class (Virtual Port Com). The only other change I made to the generated code was to usb_cdc_if.c file to add the lineCoding.I've attached my clock configuration screenshot.Has anyone tried to implement a USB device on one of these black pills? If so, would you know if I'm making any obvious error with what I'm trying to do?Thank you very much,Garrett.

When I want to detect the variables of 2-d array, found it have not be support in this tool, just support for 1-d array, can anyone help to check it whether is my omission or this function is not existed.

Hi,I am working on CAN on STM32F103C8T6. I am using a Callback Function of (HAL_CAN_RxFifo0MsgPendingCallback) but soon after receiving message code hangs in Callback Function even though no data sent afterwards it.I am not getting the reason. Because this function works fine on CORTEX-M4 pocessor.However, Transmit_Interrupt is working fine. But receive interrupt is hanging.Here, is the code Snippet.Code is getting stuck in the receiver callback function (HAL_CAN_RxFifo0MsgPendingCallback)./* INTERRUPT HANG IN RECEIVER ISR FUNCTION */void HAL_CAN_RxFifo0MsgPendingCallback (CAN_HandleTypeDef *hcan) {CAN_RxHeaderTypeDef RxHeader;uint8_t rcvd_msg[5];char msg[50];if(HAL_CAN_GetRxMessage((CAN_HandleTypeDef*)&hcan,CAN_RX_FIFO0,&RxHeader,rcvd_msg) != HAL_OK){Error_Handler();}sprintf(msg,"Message Received : %s\n",rcvd_msg);HAL_UART_Transmit(&huart1,(uint8_t*)msg,strlen(msg),10);}Guys, please help.Thanks,Alankrit

Hi !Don't know if this issue relies to new version V5.6.1, but if SW4STM32 is chosen as tool chain the linker script file (*.ld) is not generated anymore!Steps to reproduce:1) generate a new project (e.g. from board selector: NUCLEO-F072RB)2) goto "Project Manager" tab:enter Project Name and Project Locationselect SW4STM32 toolchain3) press button GENERATE CODE==> the generated output folder contains no *.ld file.Same procedure with makefile as toolchain: file STM32F072RBTx_FLASH.ld is generated

I am trying to get user input from the GUI to FreeRTOS. The text area buffer is transferred from my screen1View, to screen1Presenter, to model then added to a queue. Finally, my task in FreeRTOS will check for new data in the queue every 1 second.The problem now is the received data. The user input in gui is 57346,the text area display this number correctly i.e. no space in between the numbers. But in my ucData[10] buffer, a 0 space exist in between the number i.e. 5070304060. How can I correctly transfer the user input to my main.c? Where is the cause for this ? Thank you!Other code information below if relevant.Screen1View.cpp   void Screen1View::doUpdatePIDParam() {   presenter->doUpdatePIDParamB( textArea_PBuffer, textArea_IBuffer, textArea_DBuffer, textArea_TargetBuffer); }Screen1Presenter.cpp   void Screen1Presenter::doUpdatePIDParamB( Unicode::UnicodeChar *bufferP, Unicode::UnicodeChar *bufferI, Unicode::UnicodeChar *bufferD, Unicode::Unico

So I am guessing it's the issue with the memory allocation. I followed the steps given for External addressable flash in TouchGFX documentation in STM32Cube IDE.(I am not using my application to test Quad SPI Memory: I followed the exact steps given for memory mapped mode with the same example as given in the TouchGFX Documentation)I have read application notes 4760 as well and tried that too still I am getting "???????" from memory address 0x90000000 onwards. What does that mean? Is it reading anything?This application is going to display real time data on the display. which External memory should be compatible for this? External RAM or External flash?Can you please guide me in the right direction?Thank you in advance.

Hello,I am working on a project that acquires ADC readings and saves them into a buffer in the M4 side of STM32mp157 chip on DK2 board, now I need to build a kernel module that copies the saved buffer from the SRAM to DDR on the A7 side when a certain interrupt is triggered.As I am a beginner in embedded linux world I am wondering about the way to do this, I tried memcpy() at first but errors arise when inserting the module (Can't page virtual address error), I also tried converting the SRAM address from physical to virtual before memcpy() but that didn't work as well.Is there a direct way to copy data between the memories like memcpy() or do I need to use DMA from the kernel module to copy the data, if the DMA is the way, sharing an example would be great.Thanks

I want to combine multiple card in one, can I do as I said above? If yes, how do I read the card from flash then send to st25r3917 for card simulation?

Hi,I want to use wildcard texts, which align text to right instead of left.I have empty text items (nothing but <value>), which have text area width set to full width of the screen. I need the text inside the text area to be "anchored" to right side, so that the added text will "grow" left, instead of right.Align feature does not seem to do anything.So far I cannot figure out anything else than manually call  textItemRight.moveTo(XPOS - textItemRight.getWidth(), textItemRight.getY());to align texts to right. This is cumbersome to do manually for many texts.

1- What is the deference between figure 10 and 11? And what is (S22943) in figure 11? is all I need to use active antenna inductor and capacitor? If it is yes what is the value?2- I have seen in the   in section 7 general schematic. Is it for passive antenna only?Thanksbest regards

Hi, I'm relatively new to microprocessors and everything ST. I've recently been assigned to a project that is supposed to use the LSM6DSOX to track movement within a 3D space. I have the SensorTile.box and a STM32Nucleo-L476RG board. I've been having a lot of trouble trying to use the sensor within the SensorTile.box. I tried using Unico GUI, but it won't detect my sensor when I connect it to my computer. I confirmed the SensorTile.box is on, and my computer detects its presence (I'm able to see it in the File Explorer and access the contents of the board). I have STM32CUBEIDE installed, I installed the X-CUBE-MEMS1 Additional Software Pack, I tried downloading the STM Virtual COM Port drivers, but I still can't seem to get this to work. I am running Windows 10, and have tried the most recent versions of all the above mentioned software. Can anybody help me get started, or at least steer me in the right direction? The online videos I've found have people seamlessly using Unico GUI, whi
