Hi the datasheet does not contain the thermal junction temperatures for the VFQFPN48, hence hard to work out the max thermal temps for the device. please can you supplyregardsRoss

Hi All,To start, I'm a hobbyist and although I am OK with digital, analogue and the maths surrounding design is beyond me.    I am seeking assistance in specifying the values and component suggestions for the CM Filter as noted in figure 7, page 19 of the PM8805 data sheet. If someone has a ready made solution for the following, it would be very much appreciated.   My circuit will need two power rails which I will create using two buck convertors. A 12V rail as well as a 3.3V rail. The 3.3V will only draw a constant current of around 600mA, the 12V rail will spike on occasion to 2Amps. I have designed these before and I am happy with this area.   The 12V circuit will be driving a Texas Instruments TAS5670L Class D I2S Amplifier, while the 3.3V will be driving a Microcontroller. Thanks in anticipation.  

Hi,I am using the Nucleo-N657X0-Q board and here is what I have done so far:Generated a CubeMX projectEnabled FSBL, Secure Application, Non-secure Application and ExtMemLoader projectsEnabled XSPIM, XSPI2, EXTMEM_LOADER, EXTMEM_MANAGERGenerated codeOpened the project up in CubeIDEAnd this is where I get stuck. Since the project generates 4 sub-projects, which one do I run and on which boot configuration (BOOT0 JP1 and BOOT1 JP2)?I just want to get the non secure application to run, I have added a line of code to turn the blue LED on to verify that the code is running. Purpose of this project is to understand the project structure and its method to get the code running.Can someone please describe the steps I need to follow and in which order these needs to be done?And I also want some feedback on the steps I have performed so far. Was it even needed to generate the EXTMEM_MANAGER sub project, and to enable the EXTMEM loader and manager? 

Hi Team,I came across the LSM6DSV16BX, which seems suitable for sports earbuds. Are there any compact earbud-style development boards or hearable devices available on the market?

Hello,I am looking for MEMS accelerometer for seismic application.We need low noise, up to 100Hz bandwidth, full scale +-2g range.I consider IIS3DHHC as a candidate, which has features as below:3-axis, ±2.5 g full-scaleUltra-low noise performance: 45 µg/√Hz16-bit data outputI would like to clarify what is the effective number of bits for 16bit output?How does the Sensitivity 0.076mg/LSB relates to the noise performance?Is there any other products with lower noise?Best regards,Lhagva

Hi based on the quaternion/Sensor fusion of LSM6DSV example I developed an application where I display the direction of a cube. Everything works fine, no drift, but: when I take the device move and turn it around, then put it back in the same exact position, the drawing on the PC is not back to the same direction as when I started.What is going wrong?Thx

HiI am trying to program the Cortex M33 of STM32MP257F-DK dev board using CubeIDE. I have generated the code in Cube IDE. The debugger failing to program as the board not responding.Following are my debug settings:Again I tried using STM32 Cube Programmer, no luck.But its able to detect Cortex A35 using USB DFU mode and able to flash Linux into sd card.But the MCU is unable to detect.I tried boot settings in Development Mode 0011. Also tried 0001 and 0000. Same issue.Can anybody let me know where I am going wrong?

Hello!I wonder if someone can point me to instructions on how to assign a flash memory region for TouchGFX assets on an STM32H7S78-DK, such as images and large files that won't change during an update? Currently there is a Boot and Application region setup by TouchGFX. Just need to add one for the assets so that it is not necessary to erase the whole flash and upload everything, just what is needed.Thank you

Hello,I stumbled upon a cubemx generation issue for sdmmc2 for the stm32u5g9zjt6q (I didn't have this issue with some other stm32u5xx).For a basic cubemx configuration of sdmmc2, the HAL_SD_MspInit is wrongly generated. It is a bit annoying as I have to manually edit the file for each code generation or create my own overload function (not a huge effort I concede).In the Src/stm32u5xx_hal_msp.c, void HAL_SD_MspInit(SD_HandleTypeDef* hsd) calls __HAL_RCC_SDMMC1_CLK_ENABLE();instead of __HAL_RCC_SDMMC2_CLK_ENABLE();Same for void HAL_SD_MspDeInit(SD_HandleTypeDef* hsd) with the __HAL_RCC_SDMMC1_CLK_DISABLE()I might be the only one to experience it but I put it here just in case. 

Hello,I’m working with the STM32F407VG microcontroller and I want to establish communication between the PC and the board using CAN protocol. Which USB-to-CAN adapter is recommended for CAN communication with Board.[STM32 Board] --- [USB-to-CAN Adapter] --- [PC]

Hi everyone,We're working with STiROT and TrustZone on an STM32H5 (NUCLEO-H533RE), and during the provisioning process we generate the STiRoT_Config.obk file from the STiRoT_Config.xml using the Trusted Package Creator (TPC).Our question is whether the .obk file itself is encrypted or signed during generation, and if so, which keys are used for that purpose?We're trying to determine if we need to protect any additional private keys used during .obk creation, beyond those already defined for firmware encryption and authentication.Any insight on whether the .obk file is cryptographically protected (encrypted or signed), or if it's simply a binary container holding the public and private keys for secure boot, would be greatly appreciated.Thanks in advance!

Hello,I currently upgraded to Scarthgap, and noticed that weston-touch-calibrator does not work anymore.

Dear all, Dear all,I use a NUCLEO_H7A3ZI_Q, connected through an external Arduino/Zio-type connector to an external signal generator, which outputs a constant voltage level.the input channel of the μCU appears to be saturated to 3.3V; it shows this value, even if I increase the incoming voltage to e.g. 4.0V.However, the manual DS13313 states, that this channel should be 5.0V tolerant (see attachment)Could this be related to the caution notice from the UM2408 Manual (see attachment) I wonder how the adapter board is able to saturate the value, if that is true... Many thanksL.A.

For my project, an error message must display on the screen when there's a I2C related communication error. To simulate an I2C error, I pulled out the resistor that is connected between SDA and VCC(for good working of I2C communication, a resistor between VCC and SDA is necessary). When I2C error communication occurs, I2C error callback is called, a lot of things are apparently deactivated such as systick timer etc, using of a delay halts the code(since tick value doesn't increase). The MCU can't enter presenter and view of touchgfx anymore. What  can be done so that TouchGFX works again, so that I can display the needed error message on the screen)?

Hi,I am trying to get the OEMiROT example projects running on STM32H563 from "STM32CubeH5\Projects\NUCLEO-H563ZI\Applications\ROT". The provision.bat script fails after writing option bytes (probably after enabling TZ) and tries to reconnect to the MCU, which is where the script fails.To get around this, I am trying to do what "provisioning.bat" does manually. I compiled the "OEMiROT_Boot", "OEMiROT_Appli_TrustZone" apps (secure and non-secure) in STM32CubeIDE and the expected .hex are generated. Here are the steps I followed next in STM32CubeProgrammer:Product state set to "Provisioning". At this stage, STM32CubeProgrammer confirms if default DA configuration is to be used. I select yes. Successful.Enable TrustZone. Successful.Write "OEMiROT_Config.obk". Successful.Flash all .bin and .hex compiled in "STM32CubeH5\Projects\NUCLEO-H563ZI\Applications\ROT".Set product state to "iROT Provisioned". MCU disconnects, reset problems reported, debugger cannot reconnect.I try DA. DA is in

Edit by ST Moderator: This post has been translated from Chinese to comply with the ST Community Terms and Conditions (§10.2). What is the difference between STM32F070F6 and STM32F070F6P6TR? STM32F070F6和STM32F070F6P6TR的区别是什么呢？

On STM32G0 is it faster to disable and enable interrupts using the functions __STATIC_FORCEINLINE void __enable_irq(void) { __ASM volatile ("cpsie i" : : : "memory"); } __STATIC_FORCEINLINE void __disable_irq(void) { __ASM volatile ("cpsid i" : : : "memory"); }I'm not sure what "memory" does in the above. or is the code below faster__STATIC_INLINE void __NVIC_DisableIRQ(IRQn_Type IRQn) { if ((int32_t)(IRQn) >= 0) { NVIC->ICER[0U] = (uint32_t)(1UL << (((uint32_t)IRQn) & 0x1FUL)); __DSB(); __ISB(); } } __STATIC_INLINE void __NVIC_EnableIRQ(IRQn_Type IRQn) { if ((int32_t)(IRQn) >= 0) { __COMPILER_BARRIER(); NVIC->ISER[0U] = (uint32_t)(1UL << (((uint32_t)IRQn) & 0x1FUL)); __COMPILER_BARRIER(); } }I realize using the NVIC is more fine grained but just wondering what the memory behaviors differences are of these two and if one is heavier than the other.Thanks! xxx

Hi,I am currently working with the nucleo-n657x0-q development board and trying to use the ST neural-ART NPU of the STM32N657X0 MCU. While I know that neural network models can be automatically mapped to the NPU through the STEdgeAI-core, I was wondering if there is any documentation on how I could manually program the NPU? Either through a library/API or through low level functions.Thanks in advance!

Hello Everyone, I am currently using the vl53lmz_uld_api  tto process data measured by the VL53L8CX sensor. I have also used the "example_12_cnh_data" to retrieve data from my sensor. However, the incoming data seems completely incorrect, and I don't know where the issue lies. When I hold my sensor 20-25 cm in front of an obstacle, I receive highly unreasonable data: Zone : 40, Status : 0, Distance : 1383 mm Zone : 41, Status : 13, Distance : 1892 mm Zone : 42, Status : 5, Distance : 1371 mm Zone : 43, Status : 5, Distance : 1367 mm Zone : 44, Status : 5, Distance : 1347 mm Zone : 45, Status : 5, Distance : 1370 mm Zone : 46, Status : 5, Distance : 2448 mm Zone : 47, Status : 9, Distance : 2262 mm Zone : 48, Status : 4, Distance : 2977 mm Zone : 49, Status : 0, Distance : 1398 mm Zone : 50, Status : 5, Distance : 1381 mm     Can someone please help me to understand what i am doing wrong  here is my main.c:  int main(void) { /* USER CODE BEGIN 1 */

Hello,I am listing files on the SD card using fileX. My issue that some of the files contain Czech Characters (eg. č,ž,ě,š and few more). It seems that files with czech characters are read with shortened file names. (FX_MAX_LONG_NAME_LEN is set to 256). For example file "113---Kočka ze Záběhlic.dat" is read as "113---~1.DAT". File with almost the same name length "112---Dejte mu zahrát.dat" is read correctly.So my theory is it has something to do with the character encoding.I used to read all the names correctly with fatfs in the past however this is first time I am using FileX.Any tips?regards Jeronym  

HiI got a new STM32F407VGT6 Dicovery board which is quite awesome. I have been playing with it and now I want to print stuff to a terminal via Serial. I looked up some tutotials and there they simply use the on board STLink becasue USART pins are connected between the MCU and the STLINK and gets the Serial data through USB to the computer. To do that they install VCP drivers which I also did. But when I plug in my STM32 board it does not show as an COM Port. Instead it shows as STM32 STLink.This is the tutorial I have been following. For now I am using an external Serial Converter and getting the job done. But it is messy and I would like to know how to get this done with the STLink itseld. Please share your thoughts with me.Best Regards
