Dear SupportI want to add timestamp registration to the FIFO.I already use FIFO to save gyroscope and accelerometer samples, but I'm struggling to add timestamps.Since ODR is too high for polling mode the only solution is this one.I attach some code snippets to make it clear, also consider them as pseudo code taken from a more complex structure.ism330dlc_fifo_time_set and timer_rd are not present in the library but I wrote them based on the AN5125 int32_t ism330dlc_fifo_time_set(stmdev_ctx_t *ctx, uint8_t val) { ism330dlc_fifo_ctrl2_t fifo_ctrl2; int32_t ret; ret = ism330dlc_read_reg(ctx, ISM330DLC_FIFO_CTRL2, (uint8_t *)&fifo_ctrl2, 1); if (ret == 0) { fifo_ctrl2.fifo_timer_en = val; ret = ism330dlc_write_reg(ctx, ISM330DLC_FIFO_CTRL2, (uint8_t *)&fifo_ctrl2, 1); } return ret; }​ uint64_t ism330dlc_timer_rd(stmdev_ctx_t *ctx) { uint64_t time = 0; uint8_t t0; ism330dlc_read_reg(ctx, ISM330DLC_TIMESTAMP0_REG, (uint8_t *)&t0, 1); time =

The TS3330AMR has a voltage reference, but the internal configuration of the IC is unclear.Is a reverse bypass diode, like the reverse voltage protection of a linear regulator, unnecessary?

Hi. I have a problem when trying to establish a serial communication from SPC58 to my PC. My device manager only shows SPC58EC-DISP in the "other devices" section. 1.  SPC58EC-DISP is connected with USB cable to my PC. 2. I have installed the drivers from the link that was provided in the DKReferenceCode: CP210x USB to UART Bridge VCP Drivers - Silicon Labs.  3. Installed "CP210x Windows Drivers"  and "CP210x VPC Windows" and "CP210x Universal Windows Driver" 4. I run the installer, example "CP210xVCPInstaller_x64". 5. When i try to update the drivers to the SPC58EC-DISP in the device manager, windows doesn´t find the drivers.   Kind Regards, Joona.

Good afternoon,I'm using a screen that is naturally in a portrait orientation but my application requires landscape. I've found how to rotate the entire GUI in TouchGFX, however I am finding that I need also to rotate every PNG asset I've imported 90 degrees for it to appear correctly on the simulator or the actual screen (Focus LCD).Here it is without the asset rotated:And here you'll see that I've rotated the asset 90 degrees in the `Images` section, and it appears correctly:Is this expected behaviour or is something set up incorrectly in my project? I wouldn't expect to have to rotate every single asset, in addition to the global setting being set.Thanks in advance!Julia

So it looks like there are 2.5W or 15W reference designs, does anyone have a 5W reference design? 

Dear Gfx Team,When building Gfx in CubeIDE 1.17, C++20 compiler,in file framework\include\platform\core\MCUInstrumentation.hpp ,statement 'cc_consumed += cc_temp' causes this warning../Middlewares/ST/touchgfx/framework/include/platform/core/MCUInstrumentation.hpp: In member function 'virtual void touchgfx::MCUInstrumentation::setMCUActive(bool)': ../Middlewares/ST/touchgfx/framework/include/platform/core/MCUInstrumentation.hpp:73:37: warning: compound assignment with 'volatile'-qualified left operand is deprecated [-Wvolatile] 73 | cc_consumed += cc_temp; | ~~~~~~~~~~~~^~~~~~~~~~If you could please change it tocc_consumed = cc_consumed + cc_temp;With this change the warning is no longer.ThanksFerro 

When I have the HC-06 powered from the board (either 3.3V or 5V) & try to upload to the board I get, Target no device foundError in initializing ST-LINK device.Reason: No device found on target. Yet when I unhook the module from the board everything uploads fine.So, I uploaded to check my debug serial connection without the HC-06 connected, all fine.Hook up the module, no debug . Its as if connecting it up to the power on the board knocks out the USB-ST-Link. When I plug into the 5V - debug drops, LED3 goes out & LED1 starts flashing.When I plug into to 3.3V - debug stops but the LEDs remain on.I've swapped out the HC-06 module but I still get the same behaviour, All power is being supplied by the US-ST-Link  

I am trying to use my STM32F429IGT6 CAN to receive some data from the host computer. The data is basically 4 16-bit unsigned integers (8 bytes in total), the message ID is 0x16 and uses the 11-bit standard ID format. The host computer sends messages to the bus in a 2ms cycle.On the STM32 part, I enabled CAN1 and used the interrupt function to receive and process the data. However, most of the time, the STM32 does not show any CAN messages coming, and the HAL_CAN_GetRxFifoFillLevel() function always returns 0. This makes me really confused.Below is the initialization code in my can.c file. My CAN1 is mounted on the APB1 bus with a frequency of 45Mhz, and the CAN transmission rate of the host computer and STM32 is 500kbps.void MX_CAN1_Init(void) { /* USER CODE BEGIN CAN1_Init 0 */ /* USER CODE END CAN1_Init 0 */ /* USER CODE BEGIN CAN1_Init 1 */ /* USER CODE END CAN1_Init 1 */ hcan1.Instance = CAN1; hcan1.Init.Prescaler = 6; hcan1.Init.Mode = CAN_MODE_NORMAL; hcan1.Init.Sync

hello st community!I installed today STM32CubeIDE Version: 1.17.0 Build: 23558_20241125_2245 (UTC). I want develop the firmware for a motor controller with the stspin32g4 mcu. i cant select this mcu in the target selector for the new project. why did the people at st.com not have this mcu in the target selector?what is a work around? i already run a serach for updates but it came back with no new updates.should I select a G431 mcu? but I think the pin config will be different then. i have 5 mcu stspin32g4 here.and the datasheet look like they are perfect for a small esc because the stspin32g4 with 170MHz has enough power to run FOC. and the BOM and pcb is small. thank you if you can help meFrank

Good morning,I am implementing a USB connection between my PC and the STM32F107 MCU in Device Only mode on a custom PCB. Since the PCB is powered through the USB connector (VBUS), I do not want to use the VBUS sensing pin (PA9) to activate USB communication. I have disabled it in the STM32CubeIDE settings, but the communication still does not start when I connect the cable.The only way I found to initiate USB communication between the PC and the MCU is by setting PA9 as a GPIO OUTPUT Pull-Up. Is there a way to disable VBUS detection?For reference, I am using the Middleware USB library with the Virtual COM Port (VCP) class. In the past, I used an STM32F411CEU6, and I did not encounter this issue—USB communication started immediately upon connecting the cable, even without VBUS being connected.

Hi,I am using MotionFX Library on stm32wl55 (CM4 without FPU). run at 48MHz (max frequency)it is impossible to run MotionFX_CM4F_wc32_ot.aso i use :MotionFX_CM3_wc32_ot.a and it is work. by debugging, the MotionFX_manager_run function take different execution time in different cycles?. in general, it tack 1 or 2 ms for 3 or 4 cycles, than 10 to 15 ms for the 5th cycle ! (trying Oz and Ofast optimisation)it is normal ?in attachment a screenshot for fusion execution real time record.  the lowest recommended frequency on the UM2220 is 100Hz.in my case it is just impossible to do faster !so is the library can work correctly if i set a lower frequency ?the third argument in MotionFX_manager_run(pdata_in, pdata_out, MOTION_FX_ENGINE_DELTATIME) can be a variable (set the real delta time between two execution)? because in ST examples it is always set to a fix value.if you have other recommendation to reduce the time of execution, pleas tel me :) Tha

Hello,We are investigating the VL53L7CX presence detection ToF sensor. In the datasheet its mentioned it needs to be mounted in a clean environment "The customer is advised to use a clean assembly process until aprotective cover glass is mounted." and the application note TN1532 "Recommendations for assembling dToF sensors without liners in an environmentally clean place" - states that the sensors should be mounted in a clean environment grade 1000.  Our manufacturer dose not have a 1000 grade clean room but he has 10000 grade. What would be the consequences of mounting the sensor in an 10000 grade environment ? Thank you very much!

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 ?
