Hi Sir/Mam,For our design which operates at both 1.8VDC and 3.3VDC and we use the sensor with part number LIS2DW12TR. We require the current consumption details for 3.3VDC,in datasheet we found the current consumption values only for 1.8VDC. So please provide current consumption values for 3.3VDC for both at Active state and Sleep state.RegardsVinodh

I'm sttarting with STM32. I've bought Nucleo STM32H745ZI-Q and I'm trying to bling a LED (or any other GPIO). I've downloaded CubeIDE, CubeMX is included in it. I'm tring to Toggle GPIO pin, i've tried few tutorials on yt with no luck. ST-Link is up to date. Do i need some additional software? Building process ok. Debuging also seems to be working but GPIO pins on board are LOW no matter what im doing.

Greetings,STM32WLE5 reference manual says an external TCXO should have a sinusoidal output. Clipped sine oscillators seem to be more available, do you think they would work too?Thanks!

To my current knowledge, the latest version of STMCUFinder (3.1.0, MacOS) does not include a selectable column (and/or Peripheral on the left) to select FDCAN.​Also, it does not appear that FDCAN is 'implied' by the CAN peripheral. For example, the part STM32G431x6/8/B appears to have FDCAN - according to the spec, but has no "1" marked in the CAN column (and is not selectable with CAN peripheral on the left side).​Is this the only peripheral that is missing, or is STMCUFinder to be considered incomplete/obsolete (for example, can't find USB-PD specifically either)?

Hi together,the VCONN voltage at STEVAL-USBPD27S is generated with a LDO. https://www.st.com/content/st_com/en/products/evaluation-tools/solution-evaluation-tools/psu-and-converter-solution-eval-boards/steval-usbpd27s.html#overviewUSB power delivery specifies a cable supply power of max. 1W at VCONN that means that in worst case, the SOT23 LDO generates about 1.7W loss at 9V USB output voltage. More than that, VCONN is specified with 5V, not 3.3V.How does this work? Is the duration of the VCONN at 1W limited? Is there an option to skip VCONN if output power stays at 3A, not 5A?Thank you and Regards,DRH

Hi All,freeRTOS causes Hardfault when using sscanf. When I don't use freeRTOS this works fine, so the issue is freeRTOS related.I also previously had printf causing Hardfault but I found a library named newlib which allowed printf to no longer generate the hardfault but sscanf is still a problem.Any idea on how to resolve this. I am using STM32F103 (Bluepill) Regardsonio

Hello,I'm working with a STM32F412. In my process, the STM32 will receive a firmware. The idea is to flash this firmware (that is in RAM) to the STM32 for it to execute after a reset. I don't know if it is possible.If it is not, what are the properties I should look for to be able to do so with a STM32 (if I have to change microcontroller)?

Hi ,Is ST25RU3993 module support "Any Sensor tags " like RF micron ..?

Hello everyone. I am nearly beginner of using mems sensors. The license agreement of x-cube-mems1 is SLA077 . I read this license agreement a little bit and i confused that could i use this library for my commercial product. And additionally could i use mc-sdk libraries for my commercial motor control product?

Hi Guys,I am familiarizing my self with SPC5 Studio, version: 6.0. After installing the IDE and downloading a project, the build fails due to some of the standard include files not being found. That problem was solved by adding C:\SPC5Studio6.0\eclipse\plugins\com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514\toolchain\lib\gcc\powerpc-eabivle\4.9.4\include to "CDT User Setting Entries" as a file system path.However, stdint.h still isn't behaving properly. The "wrapper" file is found but int32_t, int16_t, etc. aren't being defined properly.Any help appreciated.Thanks for Your Time,Wes

Issues:target MCU programs correctly.debug aborts on resume or run, then target runs by itself.single-stepping works, but if breakpoints are set then on resuming or running then debugger never stops at the breakpoint(s).Debugger connection lost.Shutting down...The same problem occurs with multiple boards - BluePill (F103C8xx), BlackPill (F411CEUx) and CELEX STM32F407CE.STM32CubeIDE is being run under Linux Mint 20- Cinnamon version 4.6.7 with kernel 5.4.0-58-generic, howevr an associate reports experiencing the same issue under Windows 10.STM32CubeIDE is the latest version: Version: 1.5.1  Build: 9029_20201210_1234 (UTC).The problem doesn't only occur with the Chinese ST-Link V2 - it also occurs with an ST-Link V2 on a Nucleo board.3.3V is wired to the target board from the ST-Link in addition to the 3.3V supply for the target."Debug" is configured for "Serial wire" under "SYS" in the "Pinout & Configuration" page and therefore both of the TMS_SWDIO and TCK_SWCLK pins are

Hi,I'm trying to trig a DMA from the EXTI0 input. There is a good example in the STM32Cube package for the H7: Projects\STM32H743I-EVAL\Examples\DMA\DMAMUX_RequestGenBut this example uses the BDMA and I need to use the DMA1. I tried to make some modifications to the example but without success (see https://community.st.com/s/question/0D53W00000Pnct0SAB/make-the-stm32h7-example-dmamuxrequestgen-work-with-dma1-instead-of-bdma).Reading the chapter "Block interconnect" I see that the source signal is called "exti_syscfg_exti0" when connected to dmamux2_gen20, but it is called " exti_exti0_it" when connected to dmamux1_gen6. I really don't understand what it means... For sure I use DMAMUX1 with the correct signal ID, but is there something else to change from the example using BDMA/DMAMUX2 ?Thank you.

Cube_IDE_1.4 and TouchGFX 4.16.Use the stm32f469i_Discovery Board to put the picture in the TouchGFX and upload it, and only the black screen appears.https://www.youtube.com/watch?v=12KXreXaLp0 that I have informed you hereI've seen and followed, but the result is the same.It is not easy to obtain data on stm32f469.Who can give me some advice?Please tell me how to upload a picture using TouchGFX on stm32f469.

I am designing a movement detector with the chip IIS328DQ (using INT1).For the IIS328DQ registers configuration, I use the driver https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/iis328dq_STdCNOTE: User register configuration was included in original support request, but irrelevant here.I can observe a lot of latency (5...15 seconds) between the move and its detection. But it's not an issue for me.The problem is that sometimes a move isn't detected at all (no interrupt generation on the INT1 pin). My impression is that some movements are better detected than others.Any suggestions what might be wrong?NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hi,The example DMAMUX_RequestGen works perfectly on my STM32H755 board and now I'm trying to modify it so it uses the DMA1 instead of the BDMA. I need that because at the end I would like to trigger a SPI5 RX.Unfortunately I cannot make it work, that means I don't see the output pin toggling when EXTI0 is changing. I have no error during the configuration. And no DMA error neither.Here is what I changed form the example:Use SRAM1 instead of SRAM4 for the DMA (SRC_Buffer_LED1_Toggle array)Use DMA1 instance instead of BDMAUse DMAMUX1 instead of DMAMUX2Enable DMA1 and SRAM1 clocksWhat did I forget? What shall I check?This is the source code:/*Buffer location and size should aligned to cache line size (32 bytes) */ /* Use SRAM4 for BDMA, or SRAM1 for DMA1 */ #if defined(__ICCARM__) #ifdef USE_BDMA #pragma location = 0x38000000 #else #pragma location = 0x30000000 #endif uint32_t SRC_Buffer_LED1_Toggle[2] = { 0, /*Value for LED 1 ON */ GPIO_PIN_10 /*Value for LED 1 OFF */ }; #endif  

I am not using OTG (Only host USB's) in the PCB I connected OTG_VBUS to GND. Is this problematic? I saw that it should be left open but not sure if it is connected internally

Hello,Issue 1: assert_failed() triggeredI had observed an issue wherein the file stm32h7xx_hal_timebase_tim.c generated by STM32CubeMX for STM32H753BIT6 has HAL_InitTick() implementation different from what is provided on the GitHub repository of STM32CubeH7 (One may refer to file stm32h7xx_hal_timebase_tim_template.c to check a sample implementation).I am concerned that the STM32CubeMX generated code calls only below inside HAL_InitTick():/*Configure the TIM2 IRQ priority */ HAL_NVIC_SetPriority(TIM2_IRQn, TickPriority, 0);   /* Enable the TIM2 global Interrupt */ HAL_NVIC_EnableIRQ(TIM2_IRQn);   /* Enable TIM2 clock */ __HAL_RCC_TIM2_CLK_ENABLE();(where TIM2 is the timer being used by FreeRTOS).I believe the code should be modified to:/*Configure the TIM2 IRQ priority */ if (TickPriority < (1UL << __NVIC_PRIO_BITS)) { HAL_NVIC_SetPriority(TIM2_IRQn, TickPriority ,0U);   /* Enable the TIM2 global Interrupt */ HAL_NVIC_EnableIRQ(TIM2_IRQn); uwTickPrio

I am working on USB CDC ACM device. I want to communicate with High Speed device using full speed host(NUCLEO-F411RE). As I am new to USB protocol, but I know that device starts communication in FS mode and switch to HS mode only if host respond to J-K chirp signal. Device is enumerated and detected as full speed device.Descriptor is successfully received on host It is high speed device but detected as FS to my host. Bulk endpoint(IN and OUT) size of device is 512 Bytes. Device transmits data when I send specific character to device, I transmit that data from host and host receive ACK from device.After that I am waiting for data from device, but I don't get any data.I am suspecting that it might be due to Bulk Endpoint size. When I am communication between two STM32 NUCLEO-F411RE board one as HOST and other as DEVICE then data is transmitted and received successfully.When device is connected with PC(host) I am able to get reply from device.IDE used : STM32CubeIDE

Hi. I am trying to make a tester for a PCB and implemented ADC value display and Timer PWM output with no issues thanks to examples and youtube videos.Application has 2 screens, 1 with ADC measurements and 1 with Frequency Check. When trying to update textAreaWithOneWildcard on the 1st screen there are no issues, but doing same on 2nd screen causes system to fall into Memory Management Interrupt Handler (both screens use the similar logic, names of variables and methods are different).The debugger can not provide any Error details as the issue seems to be in the Drawable class.The definition of all textAreasWithOneWildcard is similar (position, buffer lengths are different obviously).// 1st screen display update function - works with no issues void MeasurementScreenView::analogUpdate(uint32_t value0, uint32_t value1, uint32_t value2, uint32_t value3) { memset(&measurementValue_5VBuffer, 0, MEASUREMENTVALUE_5V_SIZE); Unicode::snprintfFloat(measurementValue_5VBuffer, sizeof(measure
