I have tow arrays one named adcData[] that is adc input buffer and Xbuf[] that is output buffer. Now i am calculating some paramaters... But when i use my debuger and Live variables, i get only adcData[] and Xbuf[] is "Failed to evaluate expression". Arrays are declared same way and everything is configured similarly.

Hi,Is there a way to obtain the actual SDAD location that is currently being detected. The reason for this is because I want to map out the locations and can see what are actually being triggered.I am using 4x4 ROI with 199 as the center.Thanks.

Hello. I wrote the following code to use the LSM9DS1 sensor with the STM32 WB55RG board. The current issue is that when I set the gyro to 0x18 and the accel to 0x28, as specified in the sensor datasheet, the accelerometer and gyro values are swapped when read. However, gyro x, gyro y, accel x, accel y, and accel z values are correct in terms of their output, even though they are read from the wrong position. The issue is that the gyro z value does not respond to sensor movement.void lsm9ds1_read_data_polling(void) { stmdev_ctx_t dev_ctx_imu; /* Initialize inertial sensors (IMU) driver interface */ dev_ctx_imu.write_reg = platform_write_imu; dev_ctx_imu.read_reg = platform_read_imu; dev_ctx_imu.handle = &hspi1; /* Wait sensor boot time */ platform_delay(20); /* Check device ID */ uint8_t who_am_i = LSM9DS1_ReadRegister(LSM9DS1_WHO_AM_I_AG); if (who_am_i != LSM9DS1_WHO_AM_I_VALUE) { while (1) { /* Device not found, handle error */ } } LSM9DS1_InitGyro(); plat

Hi,I created this Reset configThe address of Reset_Hnadler () is from a .map file.As the adress changes with builds, would be great to use function name.'set $pc=Reset_Handler'Is that possible ? What language is that 'set $pc ...' See chapter '3.1.5.6.2 Restart configurations' in 'UM2609 STM32CubeIDE user guide' (Eventually I'll port the handler from .s to .cpp and place it at a fixed address so that the address never change)Thanks

I want to deploy a model I've trained on my STM processor using STM32 Cube AI, but I am encountering some issues. Could someone with experience in this area assist me? I don’t see any obvious issues in my model, but there could still be something wrong with it. Since I don’t have much experience in this area, any help would be greatly appreciated.I am encountering an error when trying to perform the 'validate on desktop' operation. The error message is as follows:E010(InvalidModelError): Couldn't load Keras model W:\BYS_Tez\LSTM\model_RNN.h5, Error when deserializing class 'InputLayer' using config={'batch_shape': [None, 10, 3], 'dtype': 'float32', 'sparse': False, 'name': 'input_layer_9'}. Exception encountered: Unrecognized keyword arguments: ['batch_shape']I have attached the model. I would greatly appreciate any help with resolving this issue.

Hi all!I’m starting with secure zone projects using the STM32U575RIT6 microcontroller. First, I want a project with the secure zone active, and that jumps to the non-secure zone to print a message. However, when jumping to the secure zone (NonSecure_ResetHandler();) , it enters to error function (void HardFault_Handler(void)) .I have created a empty project, with this IOC: In secure zone, main.c: #define VTOR_TABLE_NS_START_ADDR 0x08100000ULAnd in NonSecure flash:MEMORY{RAM (xrw) : ORIGIN = 0x20040000, LENGTH = 512K /* Memory is divided. Actual start is 0x20000000 and actual length is 768K */SRAM4 (xrw) : ORIGIN = 0x28000000, LENGTH = 16KFLASH (rx) : ORIGIN = 0x08100000, LENGTH = 1024K /* Memory is divided. Actual start is 0x08000000 and actual length is 2048K */}Does anyone have an idea of what might be happening? Think you in advance! :)

Hi ST ,Originally posted an issue on github page here (https://github.com/STMicroelectronics/ispu-examples/issues/1), but have not heard back. So thought I'd sign up here and give a polite nudge :)I'll paste what I put here, for convenience:We've been using the MotionFX library for orientation estimation (yaw, pitch, and roll) on an ISM330IS - with only an accelerometer and gyroscope.The introduction of MotionFX v1.0.1 introduced some new factors to play around with...Snippet from https://github.com/STMicroelectronics/ispu-examples/blob/master/ism330is_lsm6dso16is/sensor_fusion_6x/ispu/lib/motion_fx.htypedef struct{float alpha_acc; /* Coefficient to control accelerometer mean and variance computation [0 to 1] /float alpha_gyr; / Coefficient to control gyroscope mean and variance computation [0 to 1] /float alpha_mag; / Coefficient to control magnetometer mean and variance computation [0 to 1] /float kappa_acc; / Coefficient to control accelerometer we

Hello,I'm currently working with the STM32WB55 evaluation card (P-Nucleo WB55). According to the data sheet, those MCUs supports ZigBee 3.0 which include Green Power configuration.However, I can't seem to find the Green Power Device (End device) cluster when configuring my ZigBee device on CubeMX. Would greatly appreciate any help.

Hi,i am playing with the code example BLE_p2pServer_ota with NUCLEO-WBA55 and i would like to change the BLE advertising intervall in the code (not with CubeMX).For example, if I switch on the blue LED with using ST BLE Toolbox on the smartphone, the advertising interval should change to 100ms - 200ms after BLE disconnection. If I switch off the LED, the advertising interval should be reset to the default value after the BLE connection is disconnected.My idea was to change paramA and ParamB in the file app_ble.c: /* Call ACI APIs */ switch(ProcGapPeripheralId) { case PROC_GAP_PERIPH_ADVERTISE_START_FAST: case PROC_GAP_PERIPH_ADVERTISE_START_LP: case PROC_GAP_PERIPH_ADVERTISE_NON_CONN_START_FAST: case PROC_GAP_PERIPH_ADVERTISE_NON_CONN_START_LP: { /* Start Advertising */ if (ledState == 1) { paramA = 0x64; // new min time (100ms) paramB = 0xC8; // new max time (200ms) } else if (ledState == 0) { paramA = ADV_INTERVAL_MIN; // min time default value paramB =

1) Using the definition I found here (Wolfram-Stadium).Would it be possible to add an option in the flex button to change into a flex-Stadium/button?I ask this because I saw multiple implementation of keyboards and most of them instantiate way to many object around the idea of a button (4 corners png , text, callbacks).2)(extra) I ask this because because you can't easily "stylise" a keyboard via Designer.It feels like it is easier to just program them manually at the screen setup (i.e.: Gaetan's T9KeyboardCustomWidget).1b) The only obvious thing that I see is to set a radius_pixel and that would limit the minimal size to not be smaller than a circle. Not sure if customizing the edge with a custom spline would make sense (easing function from the Academy videos).

Dear Community member,In L9963E burst response for 0x78, we are getting only 17 response frames out of 18 after feedback response.Last frame 18 is missing. Also the cell 7,8,9,10 is disable, while it is showing no data(for disable cell) for cell 6,7,8,9.Seems like frame is shifted one above.Also the cell voltage data in burst response(Vcellx field in response frame 1 to 14) is consistent compared to voltage read by individual voltage sense register Vcellx.what could be possible reasons for frame loss ?Adding spi signals in logic analyser for reference.  Regards,bitBuddy

Dear Community members,I have connected 2 node in ring configuration, and working on an custom pcb for BMS.In registers Faults1, Fault_L_line_status is always 1, while all other fields of Faults1 and Faults2 registers are 0. Also the OVRLATCH is not detected. What could be cause to set 'Fault_L_line_status' 1 and where could I check to diagnose.screenshot for expression view is added for reference for both nodes 1 and 2. Regards,bitBuddy

Hello everyone,I’m writing this post because I have never worked with NFC/RFID technology before, and I need help with implementing a device. I have created my own electronic circuit based on the ST25R3911B and STM32F103. So far, I have downloaded the NFC5 library and started reading its technical documentation. However, I’m not sure what to do next. I would greatly appreciate an explanation on how to create a sample program in STM32CubeIDE for reading the UID of an RFID tag, as well as how to implement the NFC5 library in this project.Thank you in advance for your help!

Hello everyone, I had no internet connection in my computer, so I cant create a TouchGFX project with board. I had TouchGFX generetor in my STM32CubeIDE software packages manager.    Do you guys know how can I create a project for my STM32H747I disco card without an internet connection or how can I download the STM32H747I board package and implement for TouchGFX. 

Hi, I'm using STM32L0 series MCU to configure the RTC to wake up after 24 hour during sleep/standby mode. Understand that we need to configure the Wake up clock to use 1Hz with 1 bit wake up counter added so that it can have the wake up time from 18h to ~36h.Anyone know what number of wake up counter I have to set in order to have 24 hours wake up time? The wake up counter is 16 bit with max value of 65535.if configure the Wake up clock to use 1Hz with 1 bit wake up counter added (RTC_WAKEUPCLOCK_CK_SPRE_17BITS), we can set the wake up time range from < 1hour up to 36h  or from 18h up to 36h?  

Good Morning,I'm trying to setup the STM32U083C-DK dev kit.  The user manual UM3292 Getting Started section, step 2, mentions installing the STLINK-V2EC USB Driver, but the link referenced doesn't take me to the driver.  Where can I find the driver?  Or is there a newer driver?  My workstation is a Win 11.  Gordon Margulieuxgordonmx@gmail.com

Hello.I am working on the LSM110A communications module project https://github.com/Support-SJI/LSM110A and I want to enable the necessary peripherals to be able to communicate the module with a MEMS using the SPI standard.The first thing I developed was the creation of a project, in STM32CubeIDE, in which I configured the SPI communication to the STM32WLE5CCU6 module. I created the code and used the source files (.c), which are included there, within the LSM110A project.Inside the “Drivers/STM32WLxx_HAL_Driver” folder of the LSM110A project, I created a file with the “link to file in file system” configuration and linked the source file “stm32wlxx_hal_spi.c”. Likewise, I performed the above procedure but with the “spi.c” file that is hosted in the “Application/User/Core” location; I also made sure that, in the folder containing the header files (.h), the “stm32wlxx_hal_spi.h” and “spi.h” files were included.My problem is that, when I made the linking of the “spi.c” file to the LSM

Hi,I don't have any experience in RF design but I need to design the matching circuit for this RFID antenna (PDF attached) to work with the ST25R100 (PDF also attached).(NOTE: IF for some reason that antenna cannot be used, can you please suggest some other [ideally] rectangular antennas that can be used and that are FLEXI-PCB TYPE because we need to attach it to a curved plastic surface). As long as the RFID card can be read reliably every time from a distance of at least 20mm, then it is acceptable. I saw the reference design but the values are different. And after trying to play with the ST tuning tool I still don't know what values to put into some of the fields: https://eds.st.com/nfc-tuningcircuit/ From the datasheet, I assume the values to input in the software are as follows: antenna self resonance = 13.56MHz, DC Resistance 2,000mR and inductance 2,000nH. Correct? BUT... These are not clear to me in the tool input fields:- should I use series or parallel res

I'm looking to integrate a ToF into our product for gesture recognition. I have my eyes on theVL53L8CH, VL53L8CX and the previous VL53L7CH, VL53L7CX. I understand the difference between the different generations. But I've been all over the datasheet, and yet I can't find the difference between the so call "AI enabling" CH ones, and the "High Performance" CX ones. Is there an actual difference, or is it just a marketing gimmick.Thanks!https://www.st.com/en/imaging-and-photonics-solutions/vl53l8cx.html 8cxhttps://www.st.com/en/imaging-and-photonics-solutions/vl53l8ch.html 8chhttps://www.st.com/en/imaging-and-photonics-solutions/vl53l7cx.html 7cxhttps://www.st.com/en/imaging-and-photonics-solutions/vl53l7ch.html 7ch
