I need to simulate some external data while running simulator. For example, our device reads temperatures and I need some way to pass those temperatures (simulate) to simulator. Is there any way that is ready for this? Or I must write WinAPI code for that (sockets, COM, IPC, etc.)?

Hello thereI have a custom board based on STEVAL-IDB011V2 EVM. Is the same schematic but I have a problem with this. Apparently it boots but not run... When I flash "Hello World" example I have some issue that I can't check why.... The expected message does not is sent complete. So I have this output:In this test, I reset the board sometimes. Some times it shows "Applicat", "Applicati", (Probably bootloader output?) Some times it shows truncated "Hello World". I checked voltage levels by https://www.st.com/resource/en/application_note/an5503-bringing-up-the-bluenrglp-bluenrglps-devices-stmicroelectronics.pdf application note (bringing up the bluenrglp devices).I tried the Power Supply test (flashing DTM Firmware - UART without update) and VDDA thats we expect 1.2V, I measured 0V. The Core voltage (VCAP) I measured 1.2V as expected.I also tried flash other firmware examples without success.Can someone help me?

Hello,during testing Zigbee_OnOff_Client_SED example, hard fault in time of joining network happen, when logging with ZB_LOG_MASK_LEVEL_3 or higher is configured. With ZB_LOG_MASK_LEVEL_2 or lower example works fine.Hard fault analyzer report PRECISERR with BFAR 0x280027. Origin seems to be in the ZbLogPrintf (see attached screenshot with stack). Because it's library, it's out of my range. Depth, lqi, pjoin values are reported weird. See next log. Any suggestion, except keeping log mask level low?Thanks, Slavomir Tomascik  ZIGBEE Application Init StackLayers Init (startupMode = 3) Adding endpoint 17 (0x11), profile = 0x0104, mem = 108 ********************************************************** Network config : CENTRALIZED END DEVICE Application Flashed : Zigbee OnOff Client .

I have a problem programmatically setting RDP to level 1.My code is:OBInit.RDPLevel = OB_RDP_LEVEL_1;OBInit.OptionType = OPTIONBYTE_RDP;ret = HAL_FLASH_Unlock();ret = HAL_FLASH_OB_Unlock();/* Clear SR register */CLEAR_BIT(FLASH->SR, FLASH_SR_BSY);ret = HAL_FLASHEx_OBProgram(&OBInit);ret = HAL_FLASH_OB_Lock();ret = HAL_FLASH_Lock();HAL_Delay(2000);ret = HAL_FLASH_OB_Launch();// shouldn't get to this point, as processor will resetI had to put in the clear pf FLASH->SR, otherwise the "FLASH_WaitForLastOperation" would fail inside "FLASH_OB_RDPConfig". I've no idea why the flash should be busy at this stage.Whether or not I run this under the debugger, the RDP byte never changes. The last HAL_Delay is to give the flash chance to be written properly before the launch resets the processor.

In CubeMX when configuring a SPI peripheral I can only choose either 8 or 16 bit, but the STM32G491 reference manual says data size can be from 4 to 16 bit. Is this a bug in CubeMX?(using the newest CubeMX version)

Hello,I struggle to use the LSE clock as a source for timer LPTIMER1. My MC is a STM32L051R8Tx and I am using Keil MDK-Lite. ARM Compiler default 5.For debugging purpose I am using the following settings: PSC = 1; ARR = 3275; Interrupt: Auto-reload match. In the IRQ handler I toggle a LED to measure the frequency by use of a manual stop-watch.I cant measure the 32,768 kHz. Instead I measure the following: with printf() statement in loopwith debuggerLowest drive~3,276kHzwith printf() statement in loopwithout debuggerLowest drive~3,276kHz    without printf()with debuggerLowest drive~150Hzwithout printf()without debuggerLowest drive~50Hz The frequency is approx. factor 10 less and will dramatically go down when I remove the printf statement inside the while(1) loop. Can someone please give me some hints where I need to have a look on?bool low_power_timer_init(void){RCC->APB1ENR |= RCC_APB1ENR_PWREN; // 1: Power interface clock enabledRCC->APB1ENR |= RCC

Hi everyone,I am using an STM32h7 to program an STM32L151 using the system bootloader through usart.When I ask for the supported commands, I get that the erase command is between them but, surprisingly, when I try to use it I get a nack.Then I read that some MCUs do not support the erase command and so my first question is: does the STM32L151 support the erase (or extended erase) command?Then I tried to erase the flash enabling and then disabling the RDP level 1, that is working but, after this operation, I find also the option bytes changed respect to the default (I read {0xffff0000, 0xffff0000, 0xffff0000, 0xffff0000, 0xffff0000} instead of {0xFF5500AA, 0xff0700F8, 0xffff0000, 0xffff0000, 0xffff0000} at address 0x1FF80000).So at the moment my firmware update process is working but, instead of sending a single erase command I have to:- set RDP level 1- restart the uP- set RDP level 0- restart the uP- re-write default option bytes- restart the uPMy second question is: am I do

Hello, I'm experimenting with algobuilder, motionFX and IKS01A3 + SMK1229AAA.Btw, very cool app for investigation.My goal is to obtain vertical speed. As motionFX provide gravity vector with magnitude 1 (let's call it G) and linear acceleration vector (let's call it A).I computed the vertical acceleration with the dot product A.G which leads toAx * Gx + Ay * Gy +Az * GzIt looks like this method gives the expected result: I get the "same" curve for the "same" vertical movement whatever the orientation of the device and whatever the direction of the movement. (I used quotes for "same" because I'm moving the device by hand ie the movement is not an exact reproduction of the previous one). However, it seems that there's an offset in result which depends on the orientation. It is particularly visible when the device is not moving: there's still a residual computed speed. If I flip the board, the residual speed is inverted.You can see it on the screenshot.Here a

In my project I use TouchGFX for an STM32 microcontroller.After visually changing the view, I need to generate the updated viewBase classes in the TouchGFX Designer.Now I want to automate this process on my build-server. I am able to generate the files for the assets, but so far I am unable to generate these ..viewBase classes from the command line.So I saw an old question https://community.st.com/t5/stm32-mcus-touch-gfx-and-gui/how-to-generate-source-code-cpp-hpp-for-touchgfx-on-linux/td-p/315134 which is no longer relevant as tgfx.exe does no longer exist.With the current version there is a touchgfx executable which can be called with update: touchgfx update If I call this from the main directory of my project, nothing really seems to happen?For now added all the generated (viewbase classes) code to git, but this is really undesirable.Can someone explain to me how I can generate the updated files from a project.touchgfx file from the command line?@Martin KJEL

Hi ! I'm using the VL53L4CD sensor's example with the Nucleo-L432KC.A first problem I solved was that the VL53L4CD didn't have the adress 0x52 as in the documentation, but 0x29 (this problem has already mentioned in a topic).My current problem is that the following code return a good status but a wrong id :'''/* (Optional) Check if there is a VL53L4CD sensor connected */status = VL53L4CD_GetSensorId(dev, &sensor_id);if(status || (sensor_id != 0xEBAA)){printf("VL53L4CD not detected at requested address\n");printf("Sensor ID : %d\r\n", sensor_id);return status;}'''It gives back the address 0.It should be the basic code, but it doesn't work.Have you got a solution ?Thank you ! Clément Poisson.

Hi,I'm using a CR95HF NFC reader using the SPI. I have Hibernate mode problemI'm sending a command :CR95HF_Send(0x07, 14, 0x08, 0x04, 0x00 , 0x04 , 0x00, 0x18 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00);If the tag is in the field then I can go into Hibernate modeIf the tag is not in the field then I cannot switch to the Hibernate mode.The generator remains on. Current consumption. How to correctly switch the CR95HF to mode Hibernate? Thanks From Ready state to Hibernate state and back to Ready stateIn Hibernate state, most resources are switched off to achieve an ultra-low powerconsumption.The only way the CR95HF can wake-up from Hibernate state is by an external event (lowpulse on pin IRQ_IN).A basic Idle command is:>>>0x07 0E 08 04 00 04 00 18 00 00 00 00 00 00 00 00 https://www.st.com/content/ccc/resource/technical/document/application_note/93/7e/d9/bc/44/d4/40/d4/DM00034250.pdf/files/DM00034250.pdf/jcr:content/translations/en.DM0003425

I am experimenting with the USB HS peripheral on the STM32U5A9NJ Discovery Kit, and noticed that there is a signal called VBUS_SENSE which is routed to PG1 (ADC4 IN8). I've configured ADC4 to sample from this pin, and notice that the sensed voltage is ~0.14V with the USB connected, and 0.0 with the USB disconnected. Is this the expected behavior? I would have expected to see a higher voltage with the USB cable connected. What is the maximum possible voltage for VBUS_SENSE? My ADC resolution is set to 12 bits, sampling time is 814.5, and Vref+ is 1.8.

Is there any function I can use to calculate the yaw and pitch directly from the IMU? Or do I need to find the quaternion(SFLP) and then calculate Euler's angle on my own? 

Where can I get schematics for these 2 dev boards in pdf format.  I found a link to the cad resources but they do not contain pdf or any recognizable format. Thanks in advance for your help !!!

Hi, how can i take values of the iks01a3 sensor (in particular LSM6DSO) in CubeIDE (or Arduino IDE). The value of the angle, and so on.
