Hello,I am conducting tests using the STEVAL-L99615C evaluation board. Despite following the L9961BMS Quick Start Guide and User Manual, I am encountering an issue with Demo 1. As shown in the attached picture, the message "No device found" continues to appear. Even when applying 20V to the B+ and B- terminals, the same issue persists.I have ensured that the hardware jumper pin settings match those specified in the Quick Start Guide. However, I am concerned that the difference in versions might be causing the problem. The version of Demo 1 in the Quick Start Guide is 1.1.0 (July 21, 2023), while the version I am testing is 1.3.0 (December 1, 2023). Could the change in version be causing this issue?Thank you for your assistance.

Hi,I cannot understand acquired ADC data order using this configuration on a STM32G030C6 device:I want to acquire 9 input channels + 2 internal channels (Temperature Sensor + Vbat). Continuous mode w/ Circular DMAHere's my Initialization routine static uint32_t adc_values[11]; HAL_ADCEx_Calibration_Start(&hadc1); // DMA continous requests: ENABLED HAL_ADC_Start_DMA(&hadc1, adc_values, 11); Everything works as expected except the channels order.adc_values[0] ---> OKadc_values[1] ---> OKadc_values[2] ---> OKadc_values[3] ---> OKadc_values[4] ---> OKadc_values[5] ---> KO This should be (afaik) the internal temperature sensor channel but I see the IN8 adc value.adc_values[6] ---> KO This should be (afaik) the IN8 channel but I see the IN9 channel.adc_values[7] ---> KO Does not match either.adc_values[8] ---> KO Does not match either.adc_values[9] ---> KO Does not match either.adc_values[10] -

Hi, I am working on Anomaly Detection in motor using ISM330ISN. As soon as I am choosing the Buffer Size of 256 in the datalogger and adding the signal, I am getting this warning of minimum RAM required is 9KB. However upto 128 buffer size, it is working fine. What is the reason that I am getting warning as I am going above 128 buffer size ? @Denise SANFILIPPO @Eleon BORLINI   

As mentioned in the datasheet of ISM330IS, we can go to accelerometer ODR of 6667 Hz but in the NanoEdge AI Studio, it is showing only upto 833 Hz. Can you tell how can we go above ODR of 833 and the. Also how can we go above Sample per axis i.e. buffer size of 256 ? @Denise SANFILIPPO @Eleon BORLINI    

Are formulas 1-4 correct in AN5894?Segment [AC] is the hypotenuse of triangle ACE, and the angle between segments [AC] and [CE] is half the dihedral angle HFOV. Then formula 1 should have a sine instead of a tangent.If I am right, in the example the angle between the segment [CB] and the opposite segment of the pyramid should be [DFoV] = 2*ASin(Sqrt(2*(Sin(60/2))^2)/Sqrt((Sin(60/2) )^2+1)) = 78.5 degrees. This value agrees with measurements made on the 3D model.

This is my first time using STM32 Cube IDE. I have run into the problem where after I program the board and everything says successful. My board does not execute my command. I have tried giving the came code to both cores so they both have something to do but that didnt work either. Here is my code. Cheers./* USER CODE BEGIN Header *//********************************************************************************* @file : main.c* @brief : Main program body******************************************************************************* @attention** Copyright (c) 2024 STMicroelectronics.* All rights reserved.** This software is licensed under terms that can be found in the LICENSE file* in the root directory of this software component.* If no LICENSE file comes with this software, it is provided AS-IS.********************************************************************************//* USER CODE END Header *//* Includes ------------------------------------------------------------------*/#i

I'm working on a project where we have to program an STM32 board to enter stop mode and only wake up when an Ethernet packet is received (wake-on-lan function). I started by installing the ThreadX OS with NetX Duo and simply enabling stop mode, but it doesn't wake up! I programmed the user button to generate EXTI interrupts, but nothing happens. I tried this same strategy without NetX Duo, and it seems to work fine.used borad: NUCLEO - H563ZIthis is what i do to start StopMode (this code is the NetxDuo thread function):static VOID nx_app_thread_entry (ULONG thread_input) { /* USER CODE BEGIN Nx_App_Thread_Entry 0 */ HAL_SuspendTick(); HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI); /* USER CODE END Nx_App_Thread_Entry 0 */ }and this is how i setup the controller: I tried what's shown in the figure, i was expecting the execution to continue after pressing the button. If it worked i would have start to work on the Ethernet wake up.if more information are n

I am writing to request specific information regarding the MTBF (Mean Time Between Failures) of the L7805 positive voltage regulator component. We are considering using this component in a critical project and need to assess its reliability for our design.I would greatly appreciate it if you could provide the exact MTBF value or direct us to where we can find this detailed information.Thank you in advance for your assistance

Hello,VL53L8CA is active product on your product list but i couldn't find a datasheet and sample.I have contacted with my local reseller buying termin is 22 weeks. Before buying i would like to have a datasheet and sample. What is the last situation of VL53L8CA?  Thanks in advance,  

See DS13560 Rev 4 (Datasheet of STM32G0B1RE)please. On the right side, it said "Six USARTs with master/slave synchronous SPI; three supporting ISO7816 interface, LIN, IrDA capability, auto baud rate detection and wakeup feature". I'm now writing courseware for my students and i cannot explain what is "USART with SPI", seems to not be "Serial peripheral interface".

Hi!I’d like to know if the Vl53L8xx product series support “SPI daisy-chaining” ?For a project, I’ll need few of those, either “straight” along a line segment ( +/- like Neonode’s ZForce sensor bar ), as a “grid”, or as an “arc section” ( that is, a curved line segment ), and I’d like to maximize speed while minimize the needed pins to control the whole set of n sensors.Regarding my choice among the whole “VL53L” product lineup, it seems it’s the only one that supports SPI, which is one of the main needs for the project, the others being the smallest amount of processing needed on the “controller” uC, and a precise-enough detection of multiplemfingers up to 10cm from the sensor in a reliable manner.From what I can read in the datasheet, it does some “auto-incrementing” stuff when begin given more than the expected 15+8 bits, which may get in the way or even prevent some tricks I had in mind totally ( I guess, wrongly ? )This being said, I could also be cool repurposing the GPIO1 of oth

Hi，I would like to know the meaning of each data in the L4CX calibration data(VL53LX_CalibrationData_t in API）, because there is a lot of data for this IC, and I would like to confirm the status of the calibration from the data.Thank you.

Hello! I'm following the STM32 tutorial on External interrupts from here and got stuck. The controller doesn't react to the press of button and the IDE for some reason switched to tab of `startup_stm32h503rbtx.s`. Reproducing steps:1. Create a new project (STM32 Project)2. Select Nucleo H503 as target board3. Go to PinOut and configuration, change mode of  PC13 to GPIO_EXTI134. Go to GPIO tab, select mode External Interrupt with Falling edge, without Pull-up ot Pull-down, set user label to B15. Go to NVIC tab and enable `EXTI Line 13 interrupt`, press `Ctrl + S`6. Go to section user Code 4 of main.c and insert the following function into it: /* USER CODE BEGIN 4 */ void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if(GPIO_Pin == GPIO_PIN_13) { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_SET); } else { __NOP(); } } /* USER CODE END 4 */ 7.

Hello,I am working with an NFC reader with an ST25R3911B chip. The problem I am experiencing is the output power. The power emitted by the antenna is too high; therefore, my task is to reduce the transmitted power.To do this I have relied on reading your application notes. From this extensive reading I realized that there are many possible solutions to reduce the output power, including:- reducing the supply voltage of the chip;- using a single-ended antenna instead of differential antenna configuration;- designing an antenna with higher impedance;- change the antenna driver output resistance;- change the chip internal regulated voltage.Unfortunately, I am working with an already defined differential architecture that excludes the first three options (because would be optimal to not change the current HW structure of the PCB). This allows me to hope for only the last two.First of all I am assuming that these last two options do not require a change in the PCB hardware, if this is true

HI team,I am working in NUCLEO-F439ZI board, now I am doing multi-channel ADC, in that I selected ADC 1 for getting the data, in ADC1 select CH3 and CH10 and Internal Temperature sensor. The data from CH3 and 10 work fine, but the internal temperature sensor value was so what different. Check my code where I do the mistake. I attached the code and result of the program for your reference./* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************

I am experimenting with the VL53L5/VL53L8 sensors. For multi-target there are the options of target order of strongest and nearest. This is not a difficult concept. However, I am curious about the algorithm for detecting the peaks in the histogram. I assume there must be some thresholding, so small peaks caused by noise(?) are ignored. I can't see a way to set the threshold, however I see this being difficult, better different thresholds work for different ambient light levels, light noise levels etc... After some quick experiments, I haven't seen any problems. Using nearest rather than strongest target order, may be more sensitive to noise conditions. Any thoughts?

My question is, using Algobuilder (or mems studio) and unicleo, can i use for example two accelerometers (on hardware nucleo 401RE, x-nucleo ISK01A3 and steval MKI233) and get data from them simultaneously to reduce the measurement error/noise?Whats the best option for this to be made?Thanks in advance

Hello everyone,i am trying to enable the secure user memory on the stm32h743 using the x-cube-sbsfu project and have the following problem:After activating the security bit, the value of the OPTSR_PRG flash register is not changing, so the security bit is not set and therefore i cannot configure the secure user memory.I use the function SFU_LL_SECU_SetProtectionSecUser from the sfu_low_level_security.c file for the configuration and before calling the function i also called HAL_FLASH_Unlock() and HAL_FLASH_OB_Unlock().Does anyone know what could be the problem?  /** * @brief Apply Secure User Memory protection. * psFlashOptionBytes: pointer to the Option Bytes structure. * pbIsProtectionToBeApplied: Output parameter to be set as "TRUE" if * this OptByte has to be modified and immediately reloaded. * @retval SFU_ErrorStatus SFU_SUCCESS if successful, SFU_ERROR otherwise. */ SFU_ErrorStatus SFU_LL_SECU_SetProtectionSecUser(FLASH_OBProgramInitTypeDef *psFlashOptionByt

I’m using the STM32H750B-DK board to explore FD CAN integration with TouchGFX.  I currently have the FD CAN working but I can't get the touchgfx to work properly.  Is there anyway to merge a touchgfx project with a STM32H750B-DK stm32cubeide?  To clarify, I want to merge a existing stm32cubeide project with a new touchgfx file.
