  I am noticing a particular issue while measuring the internal temperature sensor using ADC on an STM32H743. Since my Vref tends to vary with temperature, I am internally sampling the Vref to measure the correct reference to the temperature sensing unit.  In the main codeblock that calculates the temperature from the ADC values, I am using the built-in calibrated values for 30C and 110C. Please see below.  My ADC is setup in the following way. static void MX_ADC3_Init(void){  hadc3.Instance = ADC3;  hadc3.Init.Resolution = ADC_RESOLUTION_16B;  hadc3.Init.ScanConvMode = ADC_SCAN_ENABLE;  hadc3.Init.EOCSelection = ADC_EOC_SINGLE_CONV;  hadc3.Init.LowPowerAutoWait = DISABLE;  hadc3.Init.ContinuousConvMode = DISABLE;  hadc3.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV4;   // 64 MHz / 4 = 16 MHz  // --- CRITICAL POLLING SEQUENCE CORRECTIONS ---  hadc3.Init.NbrOfConversion = 2;  hadc3.Init.DiscontinuousConvMode = ENABLE/*DISABLE*/; // Pauses sequence after each rank  hadc3.Init.ExternalTrigCon

Hello, Our setup uses a VL53L9-based board with an STM32N657 (NUCLEO-N657X0-Q). The sensor streams RAW8 over one data lane at 1 Gbps on VC0. We are using ST’s driver, and 54 × 42 at 100 fps works well.We would like to connect three or four sensors to the N657’s CSI-2 receiver and trigger them through SYNC_IN at staggered times, so their frames do not overlap on the link. Each frame occupies the link for about 0.24 ms of the 10 ms period.We checked the receiver’s lane-state flags between frames. The clock lane remains in high-speed mode throughout streaming, while the data lane returns to the stop state (LP-11). This suggests that the sensors keep driving both lanes, which would prevent them from sharing the same lanes without a MIPI switch or bridge.Could you please clarify the following?Clock-lane mode: Can the VL53L9CX use non-continuous clock mode and return its clock lane to LP-11 between frames? If so, which register or firmware patch enables this? Pin states: Can the MIPI clock a

Hello ST Support Team,We are developing a custom evaluation board using the STM32C5A3REG6 MCU and ISM330DHCX IMU.We would like to connect our board directly to MEMS Studio via USB without using the STEVAL-MKI109D motherboard.We have reviewed UM3420 and UM3233, but would like to clarify the following: Can MEMS Studio recognize a custom STM32-based board? Is implementing the ProfiMEMS serial command protocol sufficient? Does MEMS Studio require specific USB VID/PID values, board identification commands, or firmware version responses? Is the complete communication protocol or compatible firmware source code available? Can the MLC configuration, training workflow, and sensor data visualization functions be used with custom hardware? Thank you.

Hello, I mistakenly programmed the HSM enable record into the host core DCF area at address 0x29F81A10. Could this introduce any risk of incorrect configuration? I found that I can overwrite the incorrect DCF record by programming all 0xFF. However, I am concerned that the programmed 0xFF may differ from the 0xFF of an unprogrammed blank device. Could you advise whether this operation is valid?

Hello everyone! I am following the tutorial on st wiki on how to work with STM32MP257F-DK board. Everything was going pretty good, until the “Develop on Arm® Cortex®-M33” part. This is a really important part for me, because the main reason I chose this MPU is because of the additional low-power cortex M33 and M0 co-processors. The part where I am stuck is “Modify, rebuild and reload the firmware for A35-TD flavor”. I have successfully built the “*_sign.bin” file and populated the board with it by using the “Run_Configuration” button. However past 78% the process stops and shows an error that states:“Error in final launch sequence:Failed pre launchFailed pre launchFirmware remoteproc load failed, please:     1. make sure that /lib/firmware on your target has space     2. make sure that /lib/firmware has write access   > you can open a Console View for this..”In the STM32MP2 system a log of these messages are displayed:“[ 2321.306087] remoteproc remoteproc0: powering up m0 [ 2321.307

 1. Executive SummaryDuring evaluation of the vienna_stm32g474 reference project, a data-rate decoupling effect was identified in the main PFC voltage control loop. The physical DC-link voltage feedback structure (VOLTAGE_ADC_DC_IN_PHY) is calculated inside a 2 kHz telemetry task (TIM7), but it is consumed by the main cascaded controller (DPC_LCT_PFC_Ctrl) operating within the 20 kHz interrupt loop (TIM2).Although the raw ADC data is sampled at 20 kHz (TIM2) and is immediately available in the Data Layer via DPC_CDT_DcVoltageRead(), the conversion to physical units is delayed by the low-frequency task. This feedback latency was previously masked by a 16-bit register truncation error in TIM7, which forced its real execution frequency up to ~8.7 kHz. Testing confirms that relocating the physical voltage scale conversion (DPC_ADC_VoltageDCAdc2PhyProcessData) to the 8 kHz voltage loop task (TIM6) resolves this constraint, optimizing PI controller responsiveness and improving grid current w

I have an IIS3DWB10IS connected to ESP32 host MCU via four-wire SPI.It answers the WHO_AM_I correctly and lets me read out accelerometer values successfully.However, when I want to init it to ODR larger than 20 kHz what corresponds to values 0x6 (40kHz) or 0x7 (80kHz) the read back value is 0x05 (20 kHz)What only could I be doing wrong?Do I need to configure anything beforehands setting the ODR?This is the output of my initialization function:[MINI2] R WHO_AM_I(0x0F)=0x50 expected=0x50[MINI2] BDU enable: R/W CTRL3_C(0x12), wrote=0x44 readback=0x44[MINI2] Self-test positive: configure ODR=80 kHz, FS=50 g, INT1_DRDY_XL=1[MINI2] setup readback CTRL1_XL=0x05 CTRL2_XL=0x00 INT1_CTRL=0x01

Title: STM32L431 debug launch fails every other time depending on odd/even number of Flash pagesHello,I would like to report a reproducible issue with STM32CubeIDE and an STM32L431 device.Environment MCU: STM32L431CBT6 STM32CubeIDE: Version 2.2.0 Build: 29186_20260626_0934 Debugger: ST-LINK / SWD Flash page size: 2 KB SymptomFor a long time, I had an intermittent problem when starting a debug session.Approximately every second debug launch failed.Depending on the failed attempt, I observed one of the following: The program appeared not to be loaded correctly. The CPU ended up somewhere in System Memory, for example at an address around 0x1FFFxxxx. The program started, but did not stop at the configured breakpoint. In some failed sessions, peripheral registers could no longer be read from the debugger. Initially, I suspected BOOT0, reset timing, SWD speed, or hardware noise.However, the same physical PCB worked reliably when I programmed another firmware project into exact

Hello all,I’m building a prototype of simple digital clock that shows the current time in 24 hour format with 29 LEDs. The schematic also shows a 10-LED bar, but it is not implemented at the moment. The LEDs are divided into four banks: minutes, tens of minutes, hours and tens of hours. LED cathodes are controlled via two 8-bit shift registers driven via SPI2 & two GPIO pins.I’m prototyping with a Nucleo-F410RB board which uses the STM32F410 chip. I’m using the STM32Cube and STM32CubeIDE for development.I would like to know if it’s possible/feasible to use a 4-channel timer (such as TIM1) in PWM mode for driving the four multiplex signals (MPX0..3 in the schematic below)? Or is GPIO pins with software control the best choice for this application?Thank you for your advice!LED display schematicSTM32 I/O pinsMy messy prototype setup showing the time “07:18” and one bi-LED showing the status “green”. 

RefMan RM0522 version 1.0 seems to conflict with the datasheet DS15137 - Rev 3 and DS15136 - Rev 1.RM0522 Table 23 says that all three calibration values (Vrefint, TS_CAL1 and TS_CAL2) are stored as 32-bit words.Both Datasheets’ sections 5.3.5 specify the Vrefint calibration value as 24-bit. (?! - looks like a mistake)Both Datasheets’ sections 5.3.20 show the TS_CALx values as 16-bit, as in most of other STM32 models.

We used to define STM32 pinout in STM32CubeMx since it's aware of all the possiblilities of the MCU.Then we manually need to transfer the pnout into Altium Designer Schematic. And to keep those in sync when design changes.So we want to automate that step if possible.Thus the question: How can I Import pinout generated from STM32CubeMx into Altium Designer Schematic.

I have many timers working on out H743VIT6 board, so only have Tim2, 5, 12 and above available.I have many forms of of timer triggered DMA working, but in this case as the system is near to max capacity, I need a DMA event scheduled for 52uS in the future WITHOUT using IRQs which are not time-stable enough for the purpose.So I found that timer 16 in table 98 of the RM0433 manual is show connecting to timer 2, but in CubeMX timer 15 shows no trigger source!So I though I would set up timer 5 to count down 52uS and trigger its DMA stream to write a half word to CR1 of Timer 15, that was setup to pace its own DMA stream.  Now I can get tier 15 triggering and DMA transfering it I enable it via the end of event cllback for timer 5, but DMAing to CR1 of an diabled timer doesn’t seem to work.It’s a very complicated problem! // Arm one amplitude bank, started by a TIM5 countdown delay to trigger DMA write to enable a target timer with DMA streamHAL_StatusTypeDef ArmOneBank(uint32_t *pwm_values,

Are the 4 MSbits of the M24M04E-F slave address completely fixed at 1010? So incompatible with another I2C peripheral on the same bus sharing the same 4 MSbits slave address, yes? Is there a clever way around this? (I know it can be changed on the M24M02E-F.)

Device: STM32H523xxReference Manual: RM0481Description of Issue:We are observing an apparent discrepancy between the documented initialization behavior of the Epoch programming registers and the actual silicon behavior.According to RM0481 Table 90 (Option byte loading description), both FLASH_SECEPOCHR_PRG and FLASH_NSEPOCHR_PRG are specified to be loaded from option bytes during a system reset / option byte reload sequence. This implies that after a successful boot or reload cycle, the _PRG registers should mirror the current active values found in their respective _CUR registers (FLASH_SECEPOCHR_CUR and FLASH_NSEPOCHR_CUR).However, during live register readbacks in our firmware (running at HDPL1), both FLASH_SECEPOCHR_PRG and FLASH_NSEPOCHR_PRG consistently read back as 0x00000000, even when the corresponding _CUR registers contain non-zero, successfully committed epoch values.Per §7.11.21 and §7.11.22, both _CUR registers allow Secure/Non-Secure reads and are behaving exactly as exp

Subject: STM32F373CCT6 SDADC: Wrong Readings with VDDA Reference on One Board After Environmental TestingHello ST Support Team,We use the STM32F373CCT6 to read four analog inputs with SDADC1 and SDADC2. One of our boards developed a problem during environmental testing (temperature change, dry heat, cold, damp heat cyclic and steady state), where it ran in full-function mode throughout.What happenedThe board worked correctly until day 2 of the damp heat steady-state test (40 °C). Then all four channels read with an offset (for example, a 100 V input read as 50 V). After a power cycle it worked for 2 to 3 hours, then read full scale (3.3 V) even with no input. Reflashing the firmware did not help.A couple of days later we debugged it with the same firmware (internal VDDA reference). With no input, each channel should read 1.65 V (confirmed with a multimeter at the MCU pin), but the firmware reads 1.85 V on all four channels. With the reference set to internal 1.8 V, the readings are cor
