Hi, I need to check a BULK ID for BTA40-600BRG. Could you help me on this issue?  

I've build a central device that need to connect to at least 4 hosts devices it periodically loops on a aci_gap_start_general_discovery_proc()when find a device that fits mac filter it connect itself and restart a scan periodbut when it get connected to 2nd hosts next call to aci_gap_start_general_discovery_proc() return a BLE_STATUS_NO_VALID_SLOT resultmy understanding is that CM0 can't deal with enought "state machines" as quickly mentionned in ble_defs.h /* Returned when no valid slots are available * (e.g. when there are no available state machines). */ #define BLE_STATUS_NO_VALID_SLOT 0x82UI didn't find any details in an5270Can I set maximum state machine count a bit higher in config ??thank's for any help 

Hello,I am trying to write to SPEED_RAMP using the Registers tab in MC Control Pilot, however I get the following error:ASPEP_RESP ERROR:ERROR_BAD_RAW_FORMATI am writing the data as follow for example: 6000;500Can someone help me find the right synthax? Thank you

Previously, I used the HAL_DFSDM_FilterRegularStart_DMA method to enable each of the eight filters one by one. The result was a 2.4Mhz clock output, exactly as configured in CubeMX. Now, to achieve high sync between 8 filters, i referred to the synchronization content in the reference manual(RM0455): i followed the instruction and programmed as below:/** * @brief Configurate DFSDM Filter * @retval None */ void WJ_DFSDM_FilterSyncConfig(void) { // Disable Filter to set RSYNC hdfsdm1_filter0.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter1.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter2.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter3.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter4.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter5.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter6.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; hdfsdm1_filter7.Instance->FLTCR1 &= ~DFSDM_FLTCR1_DFEN; //

Has anyone successfully used the BSD addon for netxduo inside CubeIDE?  I followed the instructions at the top of https://learn.microsoft.com/en-us/azure/rtos/netx/netx-bsd/chapter2 (the #define TX_THREAD_EXTENSION_3 int bsd_errno needed a trailing semi-colon) but the netx timeval and fd_set definitions conflict with the CubeIDE environment (/ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/select.h and /ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/sys/_timeval.h).My only reason for using BSD is to to implement ModbusTCP with libmodbus .  I would gladly opt for a native netx implementation of ModbusTCP if anyone knows of one.

Hi all,I'm currently using Motor Pilot v1.2.12 and working with Observer + PLL mode for sensorless control. I see that there are parameters C1 and C2 available for tuning, but I'm not quite sure what each of them does and how they affect the motor control.Could someone please explain the function of C1 and C2 in this context?Also, are there any reference documents or official resources that go into detail about these parameters?Thanks in advance!

I am trying to deploy an AI model on the STM32N6570-DK board. And I followed these steps:1. Open the STM32CUBEMX, choose the secure only mode, activate X-CUBE-AI, and click the FSBL, choose the application template choice.2. click the RIF3. choose the onnx and NeuralART runtime, and upload the onnx model4. The rest configurations are: profile:n6-allmem-O3; validation inputs:processed_features_reshaped.npy; validation outputs:processed_labels_oneshot.npy(these two npy files are the train set of the model, one input and one output)5. use cubeIDE to generate the code.6. move the middleware to FSBL and modify the include path and the .a pathWhen I compile the generated code, there are some errors and warnings, I am wondering how I can deal with these errors.The errors are listed below:arm-none-eabi-gcc -o "AIN6_FSBL.elf" @"objects.list" -l:NetworkRuntime1000_CM55_GCC.a -mcpu=cortex-m55 -T"D:\projForSTM32\AIN6\FSBL\STM32N657X0HXQ_AXISRAM2_fsbl.ld" --specs=nosys.specs -Wl,-Map="AIN6_FSBL.map

I am trying to measure voltages using the STM32MP157C's built-in ADC on channel 18 in differential mode, but keep getting wrong values. Linux kernel is 6.1.28.Here are the relevant bits from the Linux device tree:&pinctrl {    adc_pins_mx: adc_mx-0 {        pins {            pinmux = <STM32_PINMUX('A', 4, ANALOG)>, /* ADC1_INP18 */                     <STM32_PINMUX('A', 5, ANALOG)>; /* ADC1_INN18 */        };    };};&adc1 {    status = "okay";    assigned-resolution-bits = <16>;    channel@18 {        reg = <18>;        diff-channels = <18 18>;       

Language export fails. I followed this guide: https://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/texts-and-fonts#translationsI installed ruby for windows using rubyinstaller-3.4.3-1-x64.exe.I updated TouchGFXf Designer and the middleware folder to 4.25.0.I ruby from command prompt like this:myproject_path\Middlewares\ST\touchgfx\framework\tools\textconvertruby translations.rb export myproject_path\TouchGFX\assets\texts\assets\texts\texts.xml translations.xlsxThen I get the following error:in 'Kernel#require': cannot load such file -- nokogiri (LoadError)I have no experience with ruby and no instructions are listed.

Hello,I have a AEK-POW-NOT-X and a NUCLEO-F401RE that I would like to monitor using the AutoDevKit environnement. I downloaded AutoDevKit Studio 2.6.0 on the ST website, however I can't seem to make it work. I understand that the 2.6.0 version is meant to be a version of SPC5-Studio with the AutoDevKit environnement already integrated; but exept for the icon, name and welcome page, I can't find anything that looks like what I suppose AutoDevKit Studio looks like.When I try to create a new project, there is no "AutoDevKit project" option available. There isn't any "AutoDevKit perspective" either. I downloaded SPC5-Studio 6.0 as a comparison ; it is the exact same, exept for the fact that there are "SPC5 project" and "SPC5 perspective" available...Since AutoDevKit Studio 2.6.0 is different from all the previous versions, even though I've been watching and reading countless ressources, I can't find a clear explanation on how to make this version work. I can't tell

Hi,The STM32H7RSxx  TRM  specifies, for ETH_MACMDIOAR, the following CSR values: Bits 11:8 CR[3:0]: CSR Clock RangeThe CSR Clock Range selection determines the frequency of the MDC clock according tothe CSR clock frequency (eth_hclk):0000: MDC clock = eth_hclk / 420001: MDC clock = eth_hclk / 620010: MDC clock = eth_hclk / 160011: MDC clock = eth_hclk / 260100: MDC clock = eth_hclk / 1020101: MDC clock = eth_hclk / 1240110 to 0111: Reserved, must not be usedThe suggested range of CSR clock frequency applicable for each value (when Bit 11 = 0) ensures that the MDC clock is approximately between 1.0 MHz to 2.5 MHz frequency range.When Bit 11 is set, you can achieve a higher frequency of the MDC clock than the frequency limit of 2.5 MHz (specified in the IEEE 802.3) and program a clock divider of lower value. For example, when CSR clock is of 100 MHz frequency and you program these bits to 1010, the resultant MDC clock is of 12.5 MHz which is above the range specified in IE

Hi everyone,I'm working on a university project involving vehicle lateral control using the SPC5-MCTK-01 board. I'm using SPC5 Studio and AutoDevKit, but I'm facing issues with the setup:AutoDevKit installation via SPC5 Studio (Help → Install New Software) fails repeatedly.Launching AutoDevKit directly results in:"Error: Could not create the Java Virtual Machine. A fatal exception has occurred. Program will exit."Tested on both Windows 10 and 11 – same issue.I'd appreciate help with:Correct integration of AutoDevKit into SPC5 StudioFixing the Java VM errorTips or resources for using SPC5-MCTK-01 efficientlyThanks in advance!Best regards

HI,    I download BLE_Audio_TMAP_Peripheral firmware to STM32WBA55G-DK1 board,  and Headphones was select as Audio Configs on the borad.    When i start playing music, the audio quality was so bad.  I previously sent the input data of the headset to the audio codec chip for output on my project, and the sound quality was very good.  So why is the sound quality so poor when playing music? Is it a problem with the BLE codec or is the processing speed of the MCU too slow?

Hello,we have an issue with a STM32MP1 and EMMC. The only boot source is SDMMC2 from eMMC-Flash.So far it works fine, but when we try to initiate a "reboot" in linux the system hangs and won't start again. If we do a reset in u-boot, there is no problem at all.Also, we have two boards. One board has an eMMC THGBMNG5D1LBAIL from Toshiba (is recommeded in errata sheet) and the other board is the eMMC SDINBDG4-8G from Sandisk. At both board the Software is the same and MPU is STM32MP151CAB3T REV Z. With the Toshiba eMMC the "reboot" works everytime and with the Sandisk eMMC we have the trouble.BR    

Can anyone provide pspice model for the T1620T-8I part.Thanks

I am currently working on initializing the Ethernet peripheral on the Nucleo-H723ZG using the following environment:CubeIDE Version: 1.17.0 (MacOS)STM32Cube Firmware Version: H7 V1.12.1While calling the MX_ETH_Init() function, I encountered an issue where HAL_ETH_Init(&heth) returns HAL_ERROR. Upon debugging, I found that the problem is related to the software reset step in the initialization process.Here is the relevant portion of the code from stm32h7xx_hal_eth.c:  /* Ethernet Software reset */ /* Set the SWR bit: resets all MAC subsystem internal registers and logic */ /* After reset all the registers holds their respective reset values */ SET_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR); /* Get tick */ tickstart = HAL_GetTick(); /* Wait for software reset */ while (READ_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR) > 0U) { if (((HAL_GetTick() - tickstart) > ETH_SWRESET_TIMEOUT)) { /* Set Error Code */ heth->ErrorCode = HAL_ETH_ERROR_TIMEOUT

How do you perform a soft reset on the VL53L4CD if XSHUT is not used?  I can't seem to find an example.  I see the VL53L4CD_ULP_SOFT_RESET or VL53L4CD_SOFT_RESET is defined, but I don't know what to write to it.Also, how do you shut the sensor down without XSHUT, is telling it to StopRanging enough?Thanks.

I have the following function to verify that a full flash sector is erased but the code never seems to exit this function and I believe it gets stuck at the point where I dereference the address value. What could be the issue?static bool check_sector_erased(uint32_t sector_base) { bool ret = true; uint32_t sector_end = sector_base + SECTOR_SIZE; uint32_t addr_val = 0; for (uint32_t address = sector_base; address < sector_end; address += 4) { addr_val = (*(volatile uint32_t*)address); if (addr_val != ERASED_32) { ret = false; break; } } return ret; } 

Regarding the conflict between st-arm-clangd and the VSCode extensions "clangd" and "C/C++", I had to disable or completely remove these extensions in VSCode to use st-arm-clangd. But now I'm stuck—without them, I can't develop anything outside STM32 projects! No code navigation or intelligent recognition for other projects anymore. What a pain!

 How to import assembly files and compile them in STM32CudeIDE ?When I create a .s source file in a project, I cannot even save the file, and STM32CudeIDE only reports an error:Save failedAST is empty

I wanted to use the HDP (Hardware Debug Port) peripheral on the STM32N6 MCU (Nucleo N6 board), but CubeMX does not generate the MX_HDP_Init() function for it and does not initialize the peripheral either.Based on the reference manual, I tried configuring the peripheral at the register level but was unsuccessful.My example:LL_APB4_GRP1_EnableClock(LL_APB4_GRP1_PERIPH_HDP); *(uint32_t*)(HDP_BASE_NS + HDP_MUX) = 0xffffffffUL; *(uint32_t*)(HDP_BASE_NS) |= 0x1UL; *(uint32_t*)(HDP_BASE_NS + HDP_GPOSET) = 0xff; uint32_t hdpval = *(uint32_t*)(HDP_BASE_NS + HDP_VAL); // read back the HDP_VAL registerMy question is: how can I enable the "(from BSEC) HDPEN" signal shown in the diagram below? Thanks:Peter   

Hello,I am trying to develop a board with Bluetooth Low Energy using the STM32WBA63.I have tried to base my design on application note AN5165, but it is for the STM32WB55, and I couldn't find any application note related to RF and the WBA series.I also wasn't able to find the impedance of the RF pin of the WBA63 (QFN48 package) in the datasheet.Could you please provide to me the impedance value of the RF pin for this MCU ?Also if there are application notes for RF development on the WBA63 series, could you please provide them ? Thank you

The new revision of errata sheet for STM32H7 mentions a new error relative to SPI: It is particularly vague.What "fast software" and "slow SPI" frequency means exactly ? What is the minimum ration between both frequencies to avoid the issue ?What "add a delay" means ? How many clock cycles ?With this description it is impossible to evaluate if a software may have this issue neither to implement a workaround. 

Hello everyone, I’m working on a project using TouchGFX and I would like to know if it’s possible to display real-time curves (line graphs) that represent data coming from a sensor connected via I2C. :small_blue_diamond: I’m using a microcontroller from the STM32 series.:small_blue_diamond: The sensor communicates through I2C (temperature sensor).:small_blue_diamond: I would like to visualize this data in graphical form (curves or charts) on the display using TouchGFX. My main questions are: Is it possible to plot real-time curves or graphs using TouchGFX? Are there any built-in widgets or recommended methods to implement dynamic data plotting? What is the best way to send I2C data from the MCU to the TouchGFX GUI efficiently? Are there any examples or tutorials available? Any suggestions, code examples, or documentation links would be very helpful!Thanks in advance :folded_hands:  

Hi I'm working with the ISM330DHCXTR sensor and would like to know how long I should wait after applying power before the device is fully operational and ready to communicate (e.g., via I²C) Thanks Uri
