HiiI'm interfacing External adc with stm32f429I want to read 16-bit parallel data from ADC and connected16 lines from ADC to GPIOA GPIOA->IDRhow the data is stored in IDR and how to access the input data register continuously for every sample. Thank you.

Currently purchased with the STEVAL-SMARTAG1, it was discovered that the capability collected through the ST25 powers the L0 via EH pin VDD while collecting data from the sensor. I need to collect signals by thermocouple, which is the same transmission mode as SPI. Can I successfully collect data in this way? Any better suggestions?

Greetings!I'm designing a board using STM32WLE5CCU6 MCU and decided to use a 32-MHz Clipped Sine Wave TCXO instead of a crystal for the HSE32 clock.I have a question regarding the additional circuitry between the TCXO and MCU, is an AC coupling capacitor required? Or perhaps a load capacitor (from OSC_IN pin to GND).The datasheet mentions to add some kind of a capacitor but I'm not sure if it's an AC cap or a load cap - "For TCXO output voltage of 0.8 Vpk-pk, 10 pF can be used."Also what is the input impedance of the OSC_IN pin?My TCXO is specified for a input of 10KΩ in parallel with 10 pF, am I supposed to add those externally?I hope you can help me with these questions.BRDomagoj

Hey,I am a third year embedded electronics student and I am doing NB-IoT as an Bachelor trial. Is it possible to get the STM87M01?

STM32CubeIDE does not give me an options to select PE15 as an external interrupt source.The documentation , RM0438 suggests there are 15 possible external interrupts.  Which is true?

Hello,are we going to see CAN-XL controllers on a STM32 MCU anytime soon, or will ST only feature them in automotive MCUs for the foreseeable future?I would really need CAN-XL on a general purpose MCU for an upcoming project, where CAN-FD bandwidth won't be sufficient. And it would be great to build on an familiar Ecosystem.BestThomas

Hi all,I've a project on STM32CUBEMX and STM32CUBEIDE and I'm going to use the STEVAL-STLKT01V1(https://www.st.com/en/evaluation-tools/steval-stlkt01v1.html ) so I'll have to decide what to choose between X-CUBE-BLE1 or X-CUBE-BLEMGR.Does anyone have any suggestions?  

Hello,I noticed that INT2 is repeated in 2 pins so it confuses to identify which is INT1 and INT2. Please consider change it for future production. Regards,Pascal.

Hi,I'm using H723 for programming,and TCM ram is in use.when compiler optimization feature is on,code can not work.Is it not possible to use TCM while turning on optimization? or requires some setup? Regards,Binge

Hello everyone,I want to use the MT46V64M8P-5B:J 64Mx8 SDRAM by Micron with a STM32F745IET6 microcontroller.I'm configuring the peripheral on stm32IDE and it looks fine, the configurator automatically set PG8 as clock signal. Still, the SDRAM requires differential clock source: Is there any way to configure another uC pin as complementary clock signal? It seems stm32CubeIDE won't let me configure my clock as differential.Thank you very much in advanced.Best regardsNick  

For producing 4KHz resonant frequency sound from a buzzer using 32KHz system clock, what should be the Prescaler value and Period(ARR)? Is there any rules for defining these values?

Hello friends, i have the following setup:STM32H725ZGT6 on a selfmade board. STM32 CubeMX (default program with HSI clock and without any other peripherals). Keil µVision 5.23ULINK2 Debugger problem:I can program the controller ("verify successfull" by Keil) several times. The ULINK2 recognizes the controller (see IDCODE in the picture below) but as soon as i restart the power supply of the board (or press "debug" in Keil), the controller hangs and cannot be programmed again. In this state, the IDCODE is also not recognized anymore). What could be the reason for this?I have connected the signals:NRST (Pin27) to +3V3BOOT0 (Pin135) to GNDPDR_ON (Pin142) to GND+3V3 on all VDDs, GND to all GNDs SWDIO (Pin102) to SWDIO (ULINK2)SWCLK (Pin107) to SWCLK (ULINK2)GND to GND (ULINK2)NJTRST (Pin131) to NRST(ULINK2) I think the error must be somewhere in the hardware.I tested the toolchain on a Nucleo Board (STM32H723ZGT6) and all works fine there. 

Hi, On STM32MP1, what is voltage threshold for boot pins to be detected as 0 and 1 in digital?Will 0.61V be detected as 0? I research seem under 1.23V will be 0 and start from 1.88 or higher will be detected as 1 (if VDD = 3.3) but I am not sure this is applied for all STM32 or not. Many thanks.

Hello,We are currently in the process of developing a device that contains the STHS34PF80 IR sensor. After study of the datasheet and conducting our own tests, we have found that the sensor reliably detects a person within a 4-meter range. However, for our project requirements, we need an extended detection range of 10 meters.We understand that one way to achieve this goal is to use appropriate lenses to enhance the sensor's capabilities. We would greatly appreciate your recommendations on which lenses would be suitable for extending the range of the STHS34PF80 sensor to meet our specific needs.

I have to examples of a PCB with a H735. On one of them HAL_Init for ethernet fails due to the SWR bit of ETH_DMAMR not getting reset by hardware. On the other example of the PCB everything is working fine, running the exact same binary.Usually this seems to indicate an issue with REF_CLK. Unfortunately, REF_CLK is fine in both cases. The reference manual does not got into really more detail about what else could be missing or incorrect. As the exact same binary is working on a different PCB I expect the internals to be configured correctly by software. Hence, I assume an external signal is incorrect or in an incorrect state?Regards,Benedikt Schmidt

Currently, STM32CubeMX 6.8.0, including the one used in CubeIDE, generates an incorrect comparison when using the low layer library (LL) for reset and clock control (RCC) in a project. This happens when you change the peripheral module RCC from HAL to LL in Project Manager > Advanced Settings by clicking on the relevant line and then selecting LL.void SystemClock_Config(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_1); while(LL_FLASH_GetLatency()!= LL_FLASH_LATENCY_1) { } LL_PWR_SetRegulVoltageScaling(LL_PWR_REGU_VOLTAGE_SCALE***); while (LL_PWR_IsActiveFlag_VOS() == 0) // <-- to be corrected { }Explanation:LL_PWR_SetRegulVoltageScaling() sets bits VOS in PWR_CR1,LL_PWR_IsActiveFlag_VOS() checks the corresponding bit VOSF in PWR_SR2:Typically, the return value 0 stands for OK or HAL_OK, so LL_PWR_IsActiveFlag_VOS() returns the correct value, but STM32CubeMX inserts the wrong comparison so that the while loop is never exited on OK.Temporary fix until thi

Several questions:1. Dimensions of smallest object that can be detected.2. Maximum Sampling rate (60Hz). Can sampling time be adjusted for multiple sensor array.3. Plan to use multiple sensors. What pattern should I use to place the sensors?4. Can interrupt be generated when object is first detected?5. Any other advice would be appreciated, such as best part to use.

Hi,I have a VL53L8CX Sensor on a Satel-VL53L8 board that I am controlling with a custom microcontrollerboard that has an ESP32-S2 chip. I want the microcontroller to sleep until the sensor triggers the Int Pin, based on a threshold that I configure in advance. My knowledge of configuring thresholds goes as far as the provided example of the VL53L8CX arduino library (here). I havent really found a documentation for configuring interrupts.As far as I understand the Int Pin trigger has to be a falling edge. However I think the sleep method of the ESP does not provide a falling edge trigger for waking up (see). Only triggers on low/high level are allowed.Therefor my question is, if it is possible, to adjust what kind of trigger the Int Pin sends? And where can I find more documentation about thresholds and interrupts of the VL53L8CX? (Sorry, if I overlooked it)

Used sensor: VL53L1XApplication: TOF sensor is on bottom of a liquid filled container to measure the fill level. The light of the TOF-sensor is reflected on:1) Liquid surface (water to air, oil to air)2) Container roof surfaceIs it possible to mask out one of the reflective surfaces by limit the accepted distance for the measurement (or better: time of flight) to an expected range?E.g: The red light in the sketch will have a longer 'travel time' as the magenta light because the time to travel trough the air volume is added. If I could mask the sensor to 'see' only times below/above a given limit, I could mask out one of the reflective surfaces.

Hi, I would like using SD card with FATFS and read/write to SD card.If i have bare-metal FW without DMA template enable it is work.But if I enable DMA template f_mount, f_open return FR_OK but f_write, f_read Disc_error.I setted in CubeMX SDMMC1- SD 1bit.In DMA window added shared DMA channel (RX/TX SDMMC)In Fatfs enabled dma template.But doesnt work.If in FatFS disable dma template, read/write is work propertly.I using STM32L496RGCubeMX 6.1.1FW package 1.16.0Please help.thank you

Hi everyone, I would like use FTM feature of ST25DV.I develop the code to write EEPROM and buffer of FTM, I can read this buffer with developed Kit and ST25PC-NFC software.But I can't use APP for IOS NFC-TAP because it doesn't read FTM buffer. why?

能具体说明第二三行，代表的是什么呢？ 

Any member could advice us whether we could connect the X-NUCLEO-OUT01A2 expansion board to NUCLEO-G474RE development board.As data brief explanation is "Compatible with STM32 Nucleo development boards" but the recommendation is mentioned " The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEOG431RB development board ". This make us so confused in selection the hardware.Thanks.
