Hello, we are a manufacturer company that uses STM products. We developed a device using stm32f410 and stm32f446 products 2 years ago. We have a few processors from this old series, stm32f410 and stm32f446, and they work without any problems. However, the new stm32f410 and stm32f446 processors we bought do not work on the same card we developed 2 years ago. Periodically, the processor enters an endless reset loop. When we look at the CUB IDE debugger, we see that PADRST is active in the CSR area. But the reset input is not active. We have 200 new stm32f410 products. We cannot solve the problem. Please can you help?Thank you in advance for your help.

Hi,maybe I don't know how/where to look, but I can't find any info why in datasheet for STM32G473 there is the max value for T_trig (external trigger period) in ADC timing characteristics (see the attached image). I several datasheets for several other families and there was maximal value for f_trig instead, which seems perfectly natural to me.Could anyone point me in the right direction?Thx

Hello everyone,  I have a bunch of questions concerning the environmental impact of manufacturing a STM32  I'd like to see the impact according to as many criteria as possible from the following:  Contribution to the greenhouse effect  Particulate matter and respiratory effects of inorganic substances  Air acidification  Photochemical ozone formation  Ionizing radiation potential  Use of mineral and metal resources  Use of fossil resources  Ecotoxicity Do you know where I could find these 

I am trying to find schematic diagram for Nucleo board to know, where button is connected but there are many unnecessary files but where is Schematic? This is so annoying when press Ctrl+V and your text inserted in *** block in this form, how can I insert it as plane text? Thanks

Hello everyone,I am new to hardware programming so please excuse my basic question. Can someone please point me to the right resource to obtain data from an external pdm microphone (https://learn.adafruit.com/adafruit-pdm-microphone-breakout?view=all) from STM32H7 using arduino? Is that possible? I could not find good tutorials for this. Is learning Cube to be able to implement SAI- PDM the only option for this project? I did find the following discussion on arduino forum: https://forum.arduino.cc/t/audio-input-pdm-portenta-vision-shield/1084627 but I wanted to clarify.

Hi! :waving_hand:I have programmed a STM32WB5MMG with the SBSFU + OTA + User app. The SBSFU is able to start the user app with no problem, and the user app is able to start the OTA app.The problem comes when starting the update process. With STM32CubeMonitorRF there is no problem: the device is updated to the new version of the user app. However, when the operation is performed with the ST BLE Sensor app (iOS), the image is sent (100%), but the OTA does not restart to install the new user app and the 100% message does not disappear from the mobile app.With the normal OTA (without SBSU) I have been able to update the versions of the user app with the mobile application.My question is if STM32CubeMonitorRF and the mobile application ST BLE Sensor manage differently the OTA procedure (if so, to know these differences to be able to implement them in our mobile application where the updates will be done in production), or if it is a bug of the mobile app when managing sfb files.Best regards

Hi,I’m using the latest X-CUBECELLULAR version v7.1.0 on the BL462E-CELL1.However, the modem factory FW version (RK_03_00_00_00_11851_001) isn’t compliant with the X-CUBECELLULAR v7.1.0. From the release notes, the X-CUBECELLULAR v7.1.0 requires RK_03_00_00_00_04121_001.However, I don’t know how and where to download the RK_03_00_00_00_04121_001 modem firmware version.Your help is much appreciated.Kind regards.

I installed the Teseo-VIC3DA Evaluation Kit to my car and drove for about half an hour. The "sr" field of PSTMDR2 showed "system ready". Then I disconnected the antenna to test the DR mode. The accuracy of the DR seemed not good (the error was around 50 to 100 meters, and sometimes even worse). What is the typical accuracy of DR mode? Do you have a video that demonstrate the DR performance? 

When I run the below code snippet, it just runs for once, however when I added semicolon as in latter code piece, it runs as expected, continously. Could you please tell me why is the difference? /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ while(!(TIM6->SR & TIM_SR_UIF)) TIM6->SR = 0; HAL_GPIO_TogglePin(GPIOD, green_Pin); *************************THE SECOND CODE PIECE IS BELOW************************************** } /* USER CODE END 3 */ } /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ while(!(TIM6->SR & TIM_SR_UIF)); TIM6->SR = 0; HAL_GPIO_TogglePin(GPIOD, green_Pin); } /* USER CODE END 3 */ }

Hey team,I wanted to check if there is any bridge IC  that can convert parallel camera interface data to USB 3?And/orDo we have anything that can convert MIPI CSI-2 to USB 3? - again for a camera IC.Thank you for your help!

I just got a new stm32f103zgt6. Following the steps on how to use stm32 cube ide with the board, when I tried debugging, it says no St-link connected. I would like to know how to go about this and also how to use jtag instead of stlink as well

Running into a strange problem . We're working on a safety project and using the ST-provided STL library on an STM32H743. Failing the Flash test when attempting to get 100% test coverage. Mode details in section below.The STL library is configured to test a multiple of sectors at a time (128kByte each).Our usage model is closely derived from the Nucleo reference project that ST provides as an aid to integrate the STL library; and we're using the IAR project in that package.As of today our code utilizes 3 sectors (2 complete and one partial).The Flash test (via STL_SCH_RunFlashTM API) works well on the first 2 sectors, but always fails the 3rd.Turns out, this is because the ST-provided CRC table generator utility (STM32_Programmer_CLI.exe called with option -sl) does not generate CRCs past the last byte of in-use memory inside the 3rd sector.As an attempt to remedy the problem I'm using the memory fill option built into the IAR IDE, to force a fill to a known pattern, different from 0xF

For the SPV1050, what is the charge current to the battery? Can I set the current?Also, I would like to verify that when there is no voltage input to the SPV1050 that the two LDOs are off or not operating.

i need help in doing this i am new for this stl need some respureces ahelp would be aprricited 

Hello, Can you tell me the differences between two files linker script STM32... FLASH.id and STM32...RAM.id Regards,      

Hello st community,I work on stm32h7, and I use with RTC output alarmA, when the MCU power supple turned off, and RTC work with VBATT to wakeup some component with this signal, but this component needs any pules to wakeup and not woke up with first event ('0' to '1' or '1' to '0' )  he needs '0' to '1' and after this to go down '1' to '0' , so i have just the half way by config the alarm polarity to high,  but the SW not working yet to clear this signal, is there any way(some configuration of RTC output alarm) to auto clear RTC_SR_ALRAF flag for the output to go down without the SW?

I'am currently engaged in developing an application utilizing TouchGFX on an STM32F429I microcontroller. The initial setup, including LCD initialization, SDRAM configuration, FreeRTOS integration, and the assignment of the primary TouchGFX task, has been successfully completed with the frame buffer start address designated at 0xD0000000 in the SDRAM, resulting in satisfactory operation.I am contemplating migrating the allocation of the TouchGFX frame buffer from the SDRAM to the internal RAM of the STM32F429I. Could you advise on the procedure to reallocate the frame buffer to the internal RAM? Additionally, considering the internal RAM may already be partially utilized, how might I determine an appropriate start address for the frame buffer in this scenario? 

STM32G4 reference manual description offers only monitoring "Busy flag (BSY)" to check if SPI transfer is complete.In order to make sure the transfer is over I have to do polling of this bit. It is waste of time and resources.Is there any other reasonable way to detect the end of transfer with interrupt event generation?If I have both TX and RX, I can see the RXed data amount to know the TX is over.But in case of TX only I cannot do anything else, but polling.I believe there should be a solution, but somehow I cannot find it.Please, help.

Hi,I am using examples from the github repo to test accelerometer. I can read device id from both accel and magnetometer. Also I can read back the registers I set.  However, when it comes to read accelerometer, I read same values from all axis of the accelerometer such as A0A0A0 or 808080 and so on. Another behavior I observed is sometimes, boot register stuck as 1 after I use to BOOT bit from CTRL_REG5_A.Also I read very low values from magnetometer and 0 from temperature sensor.Is there any idea what is going wrong?Thanks.

Hi Everyone, in my previous posts i pretty much beat the bush around this subject and i did get some good supportbut i keep getting stuck with this issue.im using STM32H743ZI2 Evaluation board set to 32Mhzthe ADC is 16 bits and running on "fast channel" so therefore should be 1.2Mhz according to AN5354What i need to accomplish is to sample a large ammount of data (around 1MB, but i can settle for 100kb at this point)at a speed of atleast 1MSPSand store it reliably in internal RAM or some other external Memory device via DMAmy issues are:* RAM is limited and even though im supposed to have 1MB to my disposal i'm only managing to build the code for an array of about 220k half wordsuint16_t adc_buffer[220000]* now even when im using this "small" buffer when using DMA with it im only filling the first 65535 values.and the rest are set to 0, according to the DMA Documentation im limited to 65535 requests.* also i forgot to mention, i tested my sampling rate and it doesnt seem to be going ab

I'm attempting to use the LIS2DE12 in perhaps the simplest configuration: To directly poll the X,Y,Z registers as needed. I'm using the I2C bus. At this point, I've added some debug checks, so the current process looks like this: 1. On wakeup, I read the WHO_AM_I register to verify I'm talking to the correct device. I am.2. (debug) I read all the read/writeable registers so I can see what they are. All of them match the documentation's default values except CTRL_REG1 (0x20). Instead of the expected response of 0x07, I get 0x01. 3. I write to CTRL_REG1 (0x20) the value 0x5F. According to the docs, this should enable X, Y, Z, enable the device, and set the rate to 100Hz4. (debug) I read all the readable values. All other writeable registers are still defaults, but the CTRL_REG1 register has changed... but it doesn't contain 0x5F... it contains 0x02 !? Also interesting is the X, Y, and Z all contain non-zero values at this point, but the STATUS register reads 0x00 (no data, no o

There is an inconsistency in RTC shadow register update frequency description. Some places in text mentions that shadow register update happens once every RTCCLK period:34.3.5, 36.3.4: "Every RTCCLK periods, the current calendar value is copied into the shadow registers..."34.3.10, 36.3.8: "The copy is performed every RTCCLK cycle."And other place say that it actually happens every other RTCCLK cycle:34.6.7, 36.6.3: "Calendar values (when reading from RTC_SSR, RTC_TR, and RTC_DR) are taken from the shadow registers, which are updated once every two RTCCLK cycles."I assume that "every two RTCCLK cycles" is correct, because some other Reference Manuals state this consistently.

I'm trying to create a composite HID device, mouse+joystick. I'm using the HID mouse profile as a starting point and then add a second interface. I also used an already existing example as a guide: the Arduino core based on the HAL is maintained by ST, and implements a composite HID device mouse+keyboard, which is then used by the Arduino Mouse and Keyboard libraries https://github.com/stm32duino. For what is worth, I modified that code to implement a mouse+joystick device, and everything works as expected in Arduino. Unfortunately that code is not based on the latest HAL, so I cannot simply swap it. I then tried to use the same USB description and init function to create my device in a standard STM32CubeIDE project (below). I can see that the device initializes properly, Windows recognizes it as a composite HID device with the right characteristics, and the mouse interface works perfectly. If on the other hand I try to send data via the joystick interface, it stops transmitting. I use
