Hi All,I have configured for STM32L071xx xx controller bare metal. I was not able to find X-Cube-Mems1 for the controller.Please me know if LIS2MDL (or Mems package) is not supported on STM32L0 series?PFA screen shot of the STM32Cube IdeThanks,Milind

Hi,I am using a custom board to do some application (https://www.waveshare.com/openh743i-c-package-b.htm). On this application I should turn on LTDC (to use it with touchgfx) and I am also using the RTC.When I am only using RTC alone, the RTC clock is correct and I can see it on pin MCO1 via my oscilloscope a good shape.But when I turn on RTC and LTDC, the shape is wrong frequency (clock is slower 10seconds) is different then 32.768Khz and dutyCycle is different from time to time.Can I fix this issue via S/W?

I have two functions to calculate the phase via DFT. In both functions, real and imaginary parts are first calculated, and then the phase is determined using different methods.The first function employs the standard atan2f function from the math.h to calculate the phase. The execution time for this function is approximately 126 us.The second function utilizes the CORDIC phase function, which essentially performs the same task as atan2. Surprisingly, the execution time for this CORDIC-based approach is not much faster, taking around 121 microseconds.This result raises questions because, according to the reference manual, the CORDIC calculation should take approximately 10 clock cycles, equivalent to around 50 nanoseconds on my MCU. I am utilizing HAL_CORDIC_CalculateZO() to obtain the results.Is this expected and does anyone have an idea how to get the specified calculation time. I would be pleased with 10us?

In this document it's stated that STM32H5 devices implements the FPv5 floating-point extensions.From there, how do I know the proper flags to pass to gcc to enable the FPU? -mfpu=fpv5-sp-d16 -mfpu=fpv5-d16other ?

Hi,I am using STM32G491RE. I have to read temperature values from ADC. We  used voltage divider circuit to map the voltage values with temperature values it is non linear change between volatge and temperature.I tried below wayconst uint16_t adc_values[182] = {/* mention all voltage values*/};const uint16_t temperature_values[182]={/* mention corresponding temperature values*/};const int calibration_points = sizeof(adc_values) / sizeof(adc_values[0]);float mapADCtoTemperature(uint16_t adc_value) {for (int i = 0; i < calibration_points; i++) {if(adc_value==adc_values[i]){return temperature_values[i];}}return -1.0;} while(1){HAL_ADC_Start(&hadc1);HAL_ADC_PollForConversion(&hadc1, HAL_MAX_DELAY);uint16_t adc_value = HAL_ADC_GetValue(&hadc1);float voltage=(float)adc_value/4095.0 * 3.3;float temperature = mapADCtoTemperature(voltage);char buff[100];sprintf(buff,"ADC value: %d,voltage:%.2f V,Temperature: % .2f C\r\n",adc_value,voltage,temperature);} With ab

We are working on developing a host-module that requires two-way device authenticationThe controller we are planning to use is the STM32WL55 Series.We have the following Queries.1) Does STM32WL55 has a functionality to locally generate a certificate or a private public key pair that is not readable even by the FW itself ?Our goal is complete security of the device key/certificate.2) Does STM32WL55 has a secure storage functionality where it can store externally generated certificates/keys?Our goal is to store keys in unreadable form but still accessible for security operations.We need a brief explanation of how the mentioned functionality can be achieved on the STM32WL55 microcontroller.Also please share all the relevant documents and Example code explaining the security architecture of STM32WL55

Hello,   I created the STM32H735G-DK project with the board selector in STM32CubeIDE. The OSPI_HyperRAM_MemoryMapped project was created by the example selector. Its HyperRAM test codes were added to the STM32H735G-DK project as below. The reading sequence was repeated twice on the same address w/o increasing the memory pointer. However, the 2nd reading was always failing while the 1st reading was fine as below. Please help me to solve this issue.

Good morning everyone,I’m trying to get FDCAN working on a STM32G431 however with very limited success. I’m not able to get a valid output signal on the TX line (measured with an oscilloscope) however, if I put the FDCAN peripheral into External LoopBack Mode, then a valid message appears on the TX. Even though there are no other CAN devices connected to the CAN bus, I still expect a few (3?) valid TX messages to be registered on the oscilloscope before the buffer fills up and throws an error.In order to exclude any hardware issues on the PCB (first rev. of the PCB), I switch over to the NUCLEO-G431RB Evaluation board instead. Unfortunately, the exact same issue appeared, no valid data in Normal Mode but when in External LoopBack Mode, I do get valid TX.Right now I’m just trying to get valid TX data out on the NUCLEO in Normal Mode, so I’ve based my code on an example from the STMCubeIDE. In the main while loop, I’m simply calling AddMessageToTxFifoQ with a break point at the 1 ms HAL_

Hi,I am working with STM32G491RET6 custom board and for debugging I am using segger jlink debugger with STM32 Cube IDE 1.13.0. Everything working correctly like flashing and debugging.1.But I don't know what happened suddenly while debugging program getting struck in either Hardfault_handler() or in below function.__weak uint32_t HAL_GetTick(void){return uwTick;}2.While debugging I get to know that only one time its going inside while loop nexttime its going to either Hardfault handler or HAL_GetTick function.3.I changed the jlink debugger also I am facing same issue.I took new project in cube ide I only checked GPIO toggle with that also same issue I am facing4.With Development board same program working perfectly. Can anyone suggest what's going wrong .Thanks

I will use the STM32U575 with OCTOSPIM as Quad SPI (master) adapter.Q: The DQS signal is intended for DDR mode (I know).Could I use also DQS as input in SDR mode (when OCTOSPIM acts as SPI or QSPI master)?Idea:I want to compensate the "Round Trip Delay" on QSPI (or OCTOSPIM as SPI).Could I provide a SCLK' signal via DQS (delayed, with external DLY line) so that the READ cycle will use this signal in order to sample the response bits?Or is DQS only "working" in DDR mode (even I would 'enable' DQS also in SDR mode)?Quad-SPI in SDR mode should use DQS with external delay in order to sync D[3..0] during a READ transactions. Is it possible? (feedback SCLK with a delay line to DQS)

I have reviewed the many posts from others that have not been able to jump from a bootloader the application code and nothing that I tried worked.My MCU has its 128kB of flash in two banks, one at 0x08000000 and the other at 0x08040000.  When the MCU is reset, it starts with the code in the first bank, so this is where my bootloader is located.I have 6kB of flash reserved for storing calibration and configuration information immediately following the bootloader.  I have the application code in the second bank (0x08040000). The sole purpose of my bootloader is to allow an application software package to update the application firmware over a Modbus connection (via USB or RS485).  I am able to send the new firmware and successfully program the new application code.  I have verified this by using the STM32CubeProgrammer to compare the file to the updated flash contents.Without the bootloader, the application code works fine from STM23CubeIDE when debugging.When th

We developed a PCB that have an STM32L476. In the hardware configuration I configured the USB communcation as a Device_only and virtual com. For the hardware connection, I have the USB D+ , D- and ground connected and verified. when connecting the PCB to PC there is no new device appearing and the stm isn't appearing to the PC. Can you help what might be the reason and how to debug it. Most of the tutorial show how to do the configuration and once they connect to the PC the STM appear. Note: when the STM32 is connected to the st-link and debugging, if I plug the usb cable to the STM32, the debug stopped and give connection error.  

Please let me know if there is any evaluation board available from ST for target MCU STM32F765XX.Thanks,

Hellow community, I'm currently working with the IIS3DWBTR sensor, which I purchased from Mouser Electronics. I've encountered an issue where the `WHO_AM_I` register (0Fh) is returning a value of `0x76`, whereas the expected value is `0x7B`.The SPI bus signal seems fine, and I've checked the usual suspects such as clock speed, voltage levels, and signal integrity. The sensor initialization also appears to be correct.Has anyone else experienced this issue or have any suggestions on what might be causing this discrepancy? Any help would be greatly appreciated.Best,

Currently in the process of coding an MQ5 gas sensor, right now I was able to get the ADC value to appear on the serial terminal using PuTTy, but for whatever reason the voltage value always produces zero. I tried also changing the formula to have it produce millivolts instead of volts, but that doesn't seem to work either. Below is my code and the serial PuTTy output: /* USER CODE BEGIN Header *//**  ******************************************************************************  * @file           : main.c  * @brief          : Main program body  ******************************************************************************  * @attention  *  * Copyright (c) 2023 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 wit

Hi Team,How strong is 8 bytes NFC password given the fact that there is no lockout mechanism. Assuming an attacker with physical proximity tries to brute-force (try all combination) the password on nfc chip, How much time will be needed to crack the password? How to calculate the time it takes to perform one valid/invalid authentication attempt on nfc chip?

Hi,I am working on SPI communication between STM32G491 and ATM90E26. and I am using the SPI polling API with HAL_SPI_Transmit and HAL_SPI_Receive.My System clock is 96Mhz and I am using prescaler of 64 for SPI.CLKPolarity=Low,CLKPhase=1Edge.Communication is happening between the devices but I am not getting the correct data.there is only a shift of one bit.For examplein binary:expected: 0001 0011 1001 0100received: 0000 1001 1100 1010f I shift the received bitstream to the left I get exactly the right result.I found one solution in the forum for similar type of question(for stm32H7) It was solved withhspi1.Init.MasterKeepIOState = SPI_MASTER_KEEP_IO_STATE_ENABLE;But I am using STM32G4 with SPI Poll methodthere is no MasterKeepIOState parameter  available its giving me the error I use it.Is it due to bad configutation?or anything do I need to configure to solve it. Can anyone please suggest.Thanks  

Hello everyone,Currently, I am using the Ubuntu 22.04 operating system. I'm having a problem: when I plug ST-link into my computer, the CH340 driver doesn't convert the USB port to a traditional COM port. Therefore, the Arduino IDE does not show the port to perform serial communication as usual. I tried installing STM32CuberProgrammer to check what the error port was, then I saw the /Dev/bus/USB/001/007 port. I also tried connecting to an Arduino mega 2560, when I checked, the port still showed /Dev/ttACM0. Thanks, everyone.
