I need to develop a low-power embedded device with pedometer functionality. I'm looking at the LIS3DH because of it's low power, but there's no built-in pedometer application. I've also looked at the LSM6DSL, as it has built-in pedometer support, but the power consumption is ~8x higher. Is there a low-power IMU with built-in support for step counting? Or are these my best options? I'd like to minimize power consumption by the IMU as well as power consumption by the MCU controlling the IMU.Thanks!Brian

Hi all, I'm using pololu VL53L7CX sensor carrier board interfaced with Nucleo-L552zeq EVK for ranging application. For first level, iam using the Simple ranging application that comes with software package. Sensor api calls till getting the data seems working fine. But when viewing the result, the status is always 0. For first frame its 6, but i understood it will be 6 for the first frame. The expected status should be 5 (or 9), but for me its always 0. For now i have set the resolution as VL53L7CX_RESOLUTION_4X4 with ranging mode as VL53L7CX_RANGING_MODE_CONTINUOUS. Additionally, am not using INT pin or LPn pin. Is there anything i need to take care in the hardware side?Or is there anything to be handled in the sensor configuration in the app side?Below is the some zone result i got from a single frame:Details:{NumberOfTargets = 1, Distance = {53}, Status = {0}, Ambient = {0}, Signal = {0}}Details:{NumberOfTargets = 1, Distance = {51}, Status = {0}, Ambient = {0}, Signa

Hello,I'm using AzRTOS with FileX.  Currently, I can detect when the SD card is plugged in, then I initialize the hardware, and call fx_media_open().   The filesystem works as expected.I can also unmount the media with fx_media_close(), and the user can pull out the card.  That works.The problem is when the user pulls the SDcard when the media is open.  I detect the card removal and try to call fx_media_close(), but that just hangs the system when calling fx_media_close().  Is there a special procedure needed to recover when the media is removed?thanksMatthew 

Previously I posted a message thinking that there was an error in AN4221 regarding the checksum and whether it should be complemented.  However, looking at (for instance) the Write Memory command, I can see that the command byte sequence and the data packets employ different methods.  The command is always accompanied by its complement (i.e. XOR 0xFF, or simply ~command in C); for instance, Erase Memory (No Stretch) is sent as 0x45 0xBA.  But then the data packets are accompanied by a checksum where all the bytes are XORed together, starting with 0x00 as a base value.  E.g. 0x00 0x01 0x00 0x02 has 0x03 appended, per the AN4221 example in section 2.13.  The app note describes in section 2 "Communication safety" how for all data packets sent to the bootloader, "a byte containing the computer XOR of all previous bytes is added to the end of each communication (checksum byte).  By XOR-ing all received bytes, data plus checksum, the result at the end of th

Hello,I have assembled a PCB that contains a TESEO LIV3F + LNA + SAW, this part of the schematics is shown below.Using the teseo suite pro, the GPS receives no signal so I used a -9dB 1575MHz RF source on the input and measured the RF power at the output (GPS_RF_IN), the signal is well amplified and filtered but the LIV3F module cannot see a single satellite.Any ideas pls ?

Hello, I am having a huge problem with my development board that has a stm32f103 and STM32H757IIT6 on board.The stm32F103 works perfectly. However, I have a problem with the H757....

Hello everyone,I am generating PWM signals using the HRTIM module. Specifically, I am using Timer D to generate a PWM signal along with its complementary signal. This signal is always in phase with the master counter, setting at the timer period and resetting at the half-period.Similarly, Timer C also generates a PWM signal, but unlike Timer D, it allows phase shifting relative to Timer D.The issue arises when I try to apply a phase shift step greater than 50% of the period. In this case, instead of obtaining the desired output (shown in blue), I get an unwanted signal (shown in black). Oviously this behavior is only in the phase shift transient.From what I understand, it seems that the set in timer period, marked in purple, is being skipped. However, I am not sure if the skipped moment could be instead the one shown in blue. Or even if this is the origin of the problem.However, if I set the PWM to trigger at CMP1 = 0 of Timer D instead of PRD, and reset at CMP2=0.5*PRD, I don’t observ

Hi, is there any documentation regarding controlling brightness on STM32F75x?

Hello, I'm working with a Teseo EVB-VIC3DA.I want to control the data flow on the UART and query only the sensor data I'm interested in.After setting the baud rate to 921600, I proceeded to disable all automatically sent messages using the command $PSTMNMEAONOFF,0.My idea was to use the $PSTMNMEAREQUEST command to retrieve only the messages of interest.When sending $PSTMNMEAREQUEST,0x2,0*06, I correctly receive the $GPGGA message as specified in CDB-ID 201 of the documentation (UM2791 - TeseoVIC3 Software Instructions, STMicroelectronics).My question is whether it is possible to do the same with the DRAW messages ($PSTMDRSENMSG 30,31 and 3, bitmask 0x10000000), as I am interested in accelerometer, gyroscope, and odometer data.When I try $PSTMNMEAREQUEST,0,0x10000000*35, I only receive an acknowledgment from the device.If this is not possible, I am interested in reducing the message rate from these sensors.I attempted to do this using the command $PSTMCFGMSGL,0,50,0,0x10000000*01, but a

Hey, I am trying to build a battery pack with AEK-POW-BMS63EN BMS Slave Boards, AEK-MCU-C4MLIT1 as the Master Board, and an ISOSPI Translator.  I have made a 4S Dummy Battery to check whether I could get the cell data on the serial bus from the Master Board. As suggested, I started working with the Example code titled 'SPC58EC-AEK_POW_BMS63EN_SOC_Est_SingleAccess_CHAIN application for discovery' but although the code got flashed onto the master board, I was still reading '0' values from the slave.  Again, I tried the program titled 'SPC58EC - AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery', since I realized that there was no ISOSPI Component added in the previous project. With this example project, I started getting some values but they seem incorrect. I am getting 5.8V on Cell 1 and 0V on the rest of the cells even when I checked the voltage on the test pins on the board between C0 and C1 is 3.8V.  I am definitely doing something wrong here, I

HiI debugged the Sigfox AT_Slave example in stmcubeWLv1.3.0 package.All tutorials show how to get the board sigfox credentials through CubeProgrammer software, which once connected with a STM32WL device, shows an extra button called "sigfox credentials" (in figure).However, this does not work for me with the last 2.18 version of CubeProgrammer (tested on 2 different PCs). I had to unistall the software ad get the previous 2.17 version in order to display the extra button.   

Hello, I am using my custom PCB with the STM32H747IIT6 microcontroller. I have set up a JTAG/SWD connection. Initially, when I power up the board and connect via ST-Link, I can access the microcontroller through STM32CubeProgrammer without any issues. However, after generating a new code in CubeIDE and flashing it onto the MCU, I can no longer connect to the device. I have tried selecting all available connection modes in CubeProgrammer, but none of them work. "Error: No STM32 target found!

Hello,I'm using AzRTOS with threadX and FileX.  I have a thread with msg_queue that monitors the SD_Detect pin.  The code works properly, I detect the card insertion/removal process.  The problem is I need to re-initialize the SDMCC hardware so it can read the parameters off the SD card before I can mount the media.  I tried calling MX_SDMMC1_SD_Init() which is defined in the main.c file, but the compiler says MX_SDMMC1_SD_Init is an undefined reference. app_filex.c  has an  include "main.h" at the beginning.in "main.h" I defined the routine:/* USER CODE BEGIN EFP */ void GetDateTime(void); static void MX_SDMMC1_SD_Init(void); /* USER CODE END EFP */in app_filex.c: /* check if we received the correct event message */ syslog(SYSLOG_NOTIF, "SD Card received queued event"); if (r_msg == CARD_STATUS_CHANGED) { r_msg = 0; /* reset the status */ /* for debouncing purpose we wait a bit till it settles down */ tx_thread_sleep(TX_

Hello,I was researching ST eSIM offerings, and what I found out is that SIM provisioning goes through partner 1Global. My primary use case is to be able to provision the eSIM with multiple profiles without using 3rd party.Can you please tell me are there any eSIM solutions that I can use without going through 1Global (profile download as it is implemented in consumer eSIM devices)? And if not are there any plans in the future to offer consumer grade eSIM solutions that use provisioning without 3rd party?Thank you

Hi, We are developing PD multiport design with TCPM/TCPC architecture, but we've come across a post of CPM stack should be no longer supported for newer products. https://community.st.com/t5/stm32-mcus-embedded-software/usbc-pd-tcpm-on-the-stm32u5/m-p/637207 We understand G series have replaced much of the PD functions. That aside, our question is: is there a reason that ST no longer support TCPM/TCPC style design, whether the trend is moving to obsolete this model?Thank you. 

Hi all, I am currently using the STM32F0 MCU. I would like to understand how errors are handled when the CAN bus triggers errors. Specifically, how is the error handling process for each error category implemented? Additionally, how can the system recover to normal operation mode? Are there any related example codes or documentation that you can provide for reference? Thank you very much!

Hi everyone,I am trying to capture monochrome video using the MB1854B camera module on the STM32N6570-DK board. I am following this tutorial .My task is to obtain monochrome video at a resolution of 320 × 320 pixels at 60fpsCurrently, I am able to capture RGB video at 2592 × 1944 pixels. After checking the imx335.c file, I found only one available resolution (2592 × 1944) at 30fps and a pixel format set to IMX335_RAW_RGGB10.Is there any way to obtain my desired image resolution without any processing, just by changing register values? If so, where can I find those values? I was able to find the datasheet for the IMX335LQN, in which it was written that it can work at 60fps but it did not contain any details about the registers.
