Hi. Isn't it possible to turn on the internal pull-up resistors for SDIO lines in STM32U585?In cubeMX configuration, It doesn't show pull up option in gpio config. Also choosing pull up in the init code doesn't look like enabling it. is there anywhere in the datasheet or reference manual that explains this?

Hello all I am facing a issue my program works however when is executes this part it runs only once after that it ran into hard fault. I have attached the snap of structure part of code which cause it and also exception observation please let me know if you do have any suggestion.    

Hi, I am using the STM32 Nucleo WBA52CG evaluation board and programming it using Zephyr v3.7.0 and am looking how to set the Tx output power of the BLE radio. Are there any configs available in Zephyr for the same?  If not, alternatively please suggest a way to do this. I want to configure the Tx output power of the radio to +5 dBm. Thanks, Kaiwalya   

Hello All ,   I am using UART6 of STM32H7 series MCU for reception of 9 Byte data . UART is  losing first byte when receiving data on UART using interrupt. Setup: 1. I am using full duplex RS485 (Modbus) 2. I have 2 MAX485 IC one for reception & another one for Transmission. 3. Data I am sending : Take for second Reception Image: 02 00 35 01 00 01 00 03 3C when I do hit RxCpltCallback function in debugger I have observed that I am losing first byte of frame.  I have added two Snaps of Data reception. we can see the first byte is getting filled with 0 after that we are receiving data and at the end we are losing 9th byte. do you think there is some issue with UART configuration ? What could be the possible solution for this ? Thanks & Regards,  Devendra Mishra STM32Cube Mx Setting :    

TL;DR: I see that the WUTF bit in RTC ISR register is correctly set after the RTC wake up timer period elapses, but the interrupt service routine is never entered. RTC interrupt is enabled in NVIC though, and the interrupt service routine function name matches the one in the startup file. What's stopping the MCU from entering the interrupt routine? Hello,I am trying to periodically enter an RTC wake up timer interrupt service routine on my NUCLEO-L031K6. I don't actually go to any low power mode yet, so I do not actually "wake up", I just want to respond to the interrupt for now. I managed to do this very easily with HAL driver, but I am completely stumped with the Low-Layer (LL) driver, which is the one I intend to use in my application.This is what I did:1) Set CubeMX: activate RTC clock source, enable internal wake up, set wake up clock to 1 Hz clock, set wake up timer to 2 (just a random value, don't care), output 1 Hz signal to verify on oscilloscope the RTC is running (and I

Hello,I am implementing Secure Manager V1.2.0 from X-CUBE-SEC-M-H5 in my firmware. I am following the instructions provided in the "How to start with Secure Manager (customized configuration) on STM32H5" page.Is it possible to configure Option Bytes outside of the specific registers described on that page?To clarify, I am developing firmware for the STM32H573VI and plan to incorporate Secure Manager V1.2.0. My non-secure application requires High-Cycle Data, which can be set through the EDATA1R_PRG register.

Hello everyone,I have a question regarding the ST25R95-VMD5T. I’m working on a project where I need to read an NFC tag, specifically an ISO 14443-4A NXP MIFARE Plus tag. This tag contains a URL in an NDEF message: nordicsemi.com.I’ve successfully retrieved the 7-byte UUID using the following sequence of commands.

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.

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!
