Solved

I'm currently working with the STM32F736 Discovery board and an OV5640 sensor. I've successfully configured the DCMI for snapshot mode and enabled DCMI DMA interrupts. However, I've encountered an unusual issue. While I observe that the capture bit clears after frame completion, I'm not receiving a DMA interrupt as expected.In my current setup, I've been relying on the DMA interrupt to signify the completion of a frame. Unfortunately, this approach doesn't seem to be functioning as expected, as the 'hcamera_dcmi.State' isn't transitioning to 'HAL_DCMI_STATE_READY.'As an alternative, I've been depending on the 'CR.Capture' bit to signal frame completion. However, it appears that the frame time is longer than anticipated. I'd greatly appreciate any insights or guidance on addressing this issue.Thank you.

We are using developBoard by Emcraft with STM32MP157A.Emcraft release board with Openstlinux 4.14. If I want change devicetree of STM32MP1 i need use STM32CubeMX to export new devicetree.If i go in STM32CubeMX-->Project Manager-> Project OpenSTLinux setting, I CAN’T CHANGE version of STLinux.Is it possible to change this setting?Thanks

Where can I find the proper documentation for the functions in X -Cube - MEMS package and clear explanations for the use of functions

Hello , i am looking to know for STM32L051 how long will it take a byte to be written in to eeprom.while writing eeprom does it have any limitations like UART intteruptions? 

Hello, I currently working with a NUCLEO-H563ZI Development Board.I executed a script(Provisioning.bat) and set the product state to CLOSED according to the tutorial(How to start with OEM-iROT on STM32H573 and 563–Arm® TrustZone® enabled?).I used debug authentication to turn on secure debug and succeeded, but still couldn't connect the chip with STM32CubeProgrammer.Could you please assit me to look for steps that went wrong?Best Regard.

Hi,I'm trying a simple program with a modulo operator on a STM32G031 MCU. Everything works fine during launch. But when using debug, it says "No source code available for _udivsi3() at 0x08000204".I know that the debugger is unable to find the source code because this MCU can't do hardware division. But I don't understand why the libC can't find any way to implement this. What is the workaround ? Is there a project settings I'm missing?Thanks for your help. 

Hello Madam/sir, Recently we have purchased STM32MP157F-DK2 development board, and we are very new to this board. We are trying to install PyQt5 on this board but we are getting error "Package not found" and also we are not getting proper link to install Python "GPIO Libraries" So we required kind support for our future development by using this board.     Thanks and regards Shailesh Parashar Sr. R&D Engineer Scientific Mes Technik Pvt.

Hi, I cannot find an appropriate touch sensing library for STM32H56x.

Hello,I'm evaluating the LIS2DUX12 accelerometer by using the combination of STEVAL-MKI109V3 and STEVAL-MKI238A. In the datasheet it stablishes that it can reach down to 10 nA during deep power-down:But when I measure the current consumption through Unico-GUI, it says it consumes 2 uA which is similar to the consumption described as "ultralow-power mode" in the datasheet.I would like to know if I'm missing something to modify in order to achieve the datasheet value or is it just that STEVAL-MKI109V3 is not capable to measure such low current.Regards,Pascal.

Hello! I'm evaluating the LIS2DUX12 accelerometer by using the combination of STEVAL-MKI109V3 and STEVAL-MKI238A. In the datasheet it stablishes that in order to achieve certain current consumption is necessary to have the Temperature sensor off:But after going through all the documentation and description of the registers, I can't find any that explicitly state that by modifying certain bit I will be able to turn off the Temperature sensor. I hope you could guide me to identify where is it. The datasheet I'm reading is DS14071 - Rev 2Regards,Pascal.

Dear All,I have the STM32G431C8U6 UFQFPN48 chip mounted on the breakout board (QFPN48 to DIP48). How to use STM32CubeProgrammer and the STLINK-V3SET to program the STM32G431C8U6 UFQFPN48 chip on the breakout board? Thank you.

I'm using SPI on STM32F407VGT6 This is the code I use to check the state of the SPI_SR_RXNE bit:This is the code for the LIS3DSH accelerometer, when I send data to the accelerometer in response the accelerometer sends data to the Microcontroller.This code is working, with this code I am getting data from accelerometer.You can use other code to check the SPI_SR_RXNE status, it doesn't matter. int main() { uint8_t Read_Out_X_Y_Z_REG_Address=0xA8; uint8_t Out_X_Y_Z_Data_Separate[6]={0}; int16_t Out_X_Y_Z_Data_RESULT[3]={0}; SPI1->CR1 |= SPI_CR1_SPE; uint8_t address=0x8F; //Register address+read uint8_t result; HAL_GPIO_WritePin(GPIOE, GPIO_PIN_3, GPIO_PIN_RESET); //Chip Select while(!(SPI1->SR & SPI_SR_TXE)); SPI1->DR = address; while(!(SPI1->SR & SPI_SR_TXE)); while((SPI1->SR & SPI_SR_BSY) != RESET); while((SPI1->SR & SPI_SR_RXNE)); result=SPI1->DR; //STARTING HERE I COMMENT THE CODE FOR THE EXPERIMENT. while((SPI1->SR & SPI_

Hello,We have been using the LIS3DH for some time and recently acquire some LIS3DSH' as well.With both modules there is an internal pull-up for the SDO pin, and with the LIS3DH there is a register to control this pullup:CTRL_REG0I am not able to find a similar register for the LIS3DS, and that register address is referenced as something else.I recall that in earlier versions of the LIS3DH datasheet, this register was not provided, but added in later revisions.Is there some unlisted register for the LIS3DS to disable this internal pull-up? Or some other method?Thankyou.

I'm trying to use the internal op-amps of an STM32L471 to amplify a small current-sense voltage before measuring it via ADC. This figure from the relevant product training resource shows an internal arrow labelled "ADC," coming from the op-amp output. I assumed this meant the output from an internal opamp could be internally routed to the input of an ADC. However, I can't find a way to do this, in STM32CubeIDE or in the documentation. This should be possible, right? Would appreciate any info/advice, before I have to start bodging it externally...Cheers

Hi, I'm a beginner with TouchGFX Designer. I am trying the following gauge example with minor changes:https://youtu.be/NdGgtKwQ6fg Everything works fine in the simulator.On the device needles are not visible, and arcs appear only for left gauge andpartially. What I'm I doing wrong? I use TouchGFX Designer 4.22.1The hardware is a Nucleo-G071RB board with a X-GFX01M2 TFT display (expansionboard). A zip of the project is available here:https://fichiers.dagami.org/Nucleo-G071RB-GFX01M2-gauge.zip Thanks for any help.

I have four FSM programs working with the LSM6DSV sensor, all set to AODR/GODR of 30Hz in line with the examples I copied. Tap detect requires significantly higher ODR.  I might also want to run the SFLP at a rate higher than 15 or 30 Hz, so does this mean that I can't run the FSM when running the AODR/GODR at higher rates than 30 Hz or that I simply need to change the FSM program configuration (gulp!) to account for the desired higher rates?

Hi,I have a project where I need at least 8 PWM input channels, 10 would be great. I can't see a method to filter by PWM input on the website or in STM32CubeMX. I would like to round it down to a few devices and compare them on cost, package, etc. Is there a method to do this that I'm missing?At the moment I'm simply choosing the devices with the most timers and working through the list 1 by 1 using STM32CubeMX, this is quite a slow approach.Any advice is welcome. Thanks

I am trying to use STM32 VSC extension plugin on VSCode for a better coding experience, but error occored when I am trying to debugging.VSCode suggested that build task finish successfully in the terminal.It seems debugger failed to connect debug server. [I am not sure what debug server is and how they work. The only thing I know is that launch file has set up 2 tools named:ST-LINK_gdbserver.exe and arm-none-eabi-gdb.exe. Iguess they are connected with each other and transmit debug info by TCP(?)] I have already tried connect and reconnect my NUCLEO board on my computer. When debugger runnging, the stlink flashlight on the NUCLEO is blinking as normal (red-green-red-green). But somehow the program can't be uploaded. Also I've allowed the debugger access my network so the issue shouldn't caused by a block of my defender (I am using windows Defender only) on my computer. But, however, the debugger crashed before everything I predicted happen and here is some related infos.
