STM32 MCUs Embedded software

Is it possible to programm STM32U083C-DK as USB Device MSC? I can't see any examples of USB MSC in repository. 

Hi,I have following settings: IDE : VS Code (NRF connect plug-in) Programmer : Stm32Cube programmer (West tools used from zephyr sdk to flash and build) Stlink Debugger  OS: Zephyr  MCU: Stm32u5 series (Stm32u575) Imagetool used for the signing of the image that is part of the zephyr sdk. I'm trying to upgrade application firmware using MCUboot ( Zephyr's) bootloader and AWS FOTA .I can upgrade application firmware however, as soon as I change the size of the image slots the MCUBOOT bootloader on stm32 chips mcuboot does not upgrade the image after the download is complete and complainsE: Image in the secondary slot is not valid!.          (image attached)Then the mcuboot fallback to the primary slot image after reset.On reverting back the size of the slots it works again every time.I have put some debug messages in mcuboot which shows the hash mismatch issue (image attached for code snippet with debug message from M

Hi,   I've been trying to find something on WebSocket connections to a public domain for sending and receiving data for the past month, but couldn't find anything related to Cubeide or C library for WebSockets or the public domain, all I can see are codes associated with Arduino IDE for WebSocket which straight forward uses simple functions, Can Anyone help me with c code for the WebSocket connection to the public domain. I have initialized the w5500, static/dynamic IP allocation, I can send or receive data through the local network on a local IP address and I can create a socket server on stm32 to receive and send data locally.  

Hello all,I am learning to implement a bare-minimal code that let PTP(OC, slave mode) works with STM32H755(Nucleo-H755ZI-Q with FreeRTOS). I have read RM0399, UM2217 as well as stm32h7xx_hal_eth.c with corresponding chapters. And here is the first draft I have done: https://codefile.io/f/vny07A1hYW. In this implementation only PTP-over-Ethernet (PTPv2) will be considered.So basic ideas are:+ "DataQ_PTP_Init" implements RM0399 §61.9.9 "Initializing the System time generation". This function will be called with ETH_Init(). As well as when network cable status is changed(connected).+ "DataQ_PTP_DeInit" will be called when e.g. network cable is disconnected.+ "DataQ_PTP_SysTime_Fine_Correction" implements RM0399 Page 3037 "System time correction" algorithm, with Fine-Correction only.+ "DataQ_PTP_TSI_ISR" will verify Addend Register, has been updated correctly. By referencing RM0399 Page 3037 "System time correction" algorithm step 3-8. (When TSI interrupt is triggered.)+ "DataQ_PTP_Rx_ISR"

Deos anybody know how to change UART configuration to send MSB or LSB first? I use STM Cube MX with STM32F446RE. 

With latest STM32CubeIDE:when I try to import a project for U585 with ThreadX and NetX Duo, I get local file copy failure.Issue #1 - you need to add more details/logs, so that we can know WHICH file / package is causing the issues. It's a guessing game now.Issue #2 - the importer downloads some file, which has a license I should read. If you click there to read it - browser just says the file is not available!Issue #3 - the README.md file is missing.  Is it because I can't read the license file? I did accept the terms and conditions (god knows what they were).But, how do I know what other files are missing? Is the project now usable or not? I have plenty of disk space available.annek@jannek-P720:~$ df -h .Filesystem Size Used Avail Use% Mounted on/dev/nvme1n1p1 916G 305G 565G 36% /home Connections to GitHub are otherwise working just fine.- Multiple pushes & fetches done to GitHub today w/o issues. jannek@jannek-P720:~$ ll STM32Cube/Repository/total 360496d

Hi,recently I changed my microcontroller from STM32L152 to STM32L552. In L1 I was using the code in the following link to activate the internal bootloader.https://community.st.com/s/question/0D50X00009XkeeWSAR/stm32l476rg-jump-to-bootloader-from-softwareBut apparently that piece of code is not working on STM32L552. Actually by looking into aplication note (AN2606) in "table 153. STM32L552xx/562xx configuration in system memory boot mode" in system memory row it isn't stated that system memory contains the bootloader firmware.I was wondering how I can activate internal bootloader in the software?

Hi,I try to enable the hardware ARP Offload in a STM32H753 custom board. The problem is, that it doesn't take the given IP adresse in die MACARPAR register regardless what the sequence of code is. I tryed it before and after enabling the ARPEN bit and before and after enabling the ETH Modul. The adresse where the MACARAR register is, is staying at zero. Does anybody know, how to enable the ARP offload?Best regards,Andreas

Not able to send STM32L4S9ZIJ6 into low-power sleep mode even after using inbuilt sleep API calls. Have used HAL_PWR_EnterSLEEPMode function call after configuring SLEEP_PD register, configuring system clock to run at 2MHz & changing the regulator mode into low power regulator mode while configuring interrupt mode for device wake up. The input supply voltage is 3V.Please suggest any resolution on the issue as the board is not entering low-power sleep mode.

Hello,I am using a STM32F427 to read and write data to EEPROM Serial 256-Kb SPICAT25256. I use LL API, and DMA full-duplex over SPI. I manage myself the Chip Slect signal.I can see with logic analyser that datas are sent and received to/from EEPROM correctly.But I do not have interruption from DMA, neither input or outputstream.I do not understand why.The only way to detect the end of the transfer is to look at the BSY flag LL_SPI_IsActiveFlag_BSY(pSPI_Instance). Could-you help me to find where is the problem?Thank you for help.Best regards,                                                        FWX.I 

HiI have a project using lwIP, created by STM32Cube.It works fine, but I really want to shut OFF the debug messages.I have searched and tried a bunch of different things, but nothing seems to be able to stop it. Example of error/debug message: "netif is not up, old style port?" failed at line 744 in C:\..." Thanks

Im trying to communicate between nucleof446re board with other processor board using UART.Communication works fine when I connect my nucleo board with USB power supply but when I connect nucleo with external 3.3V or 5V supply the communication does not happen.Can I know what might be the reason. I have connect Tx Rx and GND of both the boards. Thank You

Hello I have a Nucleo-H723ZG and I'm trying to build a custom bootloader with CMSIS v2 that need a TCP connection. Since it needs to receive 1KB of data through TCP I've made the receive array long 1024 bytes, but this size crashes the whole LWIP making the TCP connection impossible and unable to respond to ping.#include <stdint.h> #include <stdlib.h> #include <string.h> #include <math.h> #include "lwip/opt.h" #include "lwip/api.h" #include "lwip/sys.h" #include "lwip/sockets.h" #include "cmsis_os.h" #include "cmsis_os2.h" #include "main.h" #include "my_tcp.h" static osThreadId_t my_tcp_task = NULL; const osThreadAttr_t my_tcp_task_attr = { .name = "my_TCP_task", .stack_size = 128 * 26, //128 * 26 .priority = (osPriority_t) osPriorityNormal, }; uint8_t tcp_received_data[PACKET_SIZE]; //Works only with 1012 instead of 1024 const char go_data = 'Y'; const char stop_data = 'N'; static void my_tcp_task(void *args); void TCP_init(void) { memset(tcp_recei

Hi,I want to compare a couple of different ways to implement the same functionality in an ISR to see which one leads to the smallest/fastest code. Is there a way - after compiling but without running a debug session - to see the disassembly code after each instruction? Also - regardless of whether there is such way or not - what other ways can you see the number of cycles it takes for a chunk of code to execute, again, without running a debug session on the micro. Thank you

Hello, all. I am currently trying to program a black pill board to print out the output from a sound sensor, for which I use the Arduino IDE 2.3.2. Used components:- STM32F411CEU6 black pill- KY-037 sound sensorCurrent connections:- the "G" pin from the sensor is connected to the "GND" pin on the black pill- the "+" pin from the sensor is connected to the "3v3" pin on the black pill- the "A0" pin from the sensor is connected to the "A9" pin on the black pillThe code:  #define DIGITAL_INPUT PA9 void setup() { Serial.begin(9600); pinMode(DIGITAL_INPUT, INPUT); } void loop() { Serial.println(analogRead(DIGITAL_INPUT)); }  This code prints out values around 270-290 and it doesn't seem like creating any loud noises has any effect on the output, and neither does changing the potentiometer on the sensor itself. What I am trying to get is an output that has a clear and visible change between different amounts of noise. I am starting to think that the current outpu

Hi,I am using a STM32L452RET6 (without any RTOS) and I would like to use the same timer for both:- drive a sounder on PWM at 4KHz (but ideally also other changing frequencies above and below 1ms time period so it can make more elaborate sounds which)- generate and also 1ms interrupt to check other tasks. What would be the best way to configure and use the micro to implement that? Thank you as always :)

Hi,during implementation of a bootloader I have encountered a problem.I'm using stm32 standard peripheral library.During writing to flash, for example at address: 0x0800C000 or 0x08010000 when the 18th line: FLASH_Status FLASH_ProgramWord(uint32_t Address, uint32_t Data) { FLASH_Status status = FLASH_COMPLETE; /* Check the parameters */ assert_param(IS_FLASH_ADDRESS(Address)); /* Wait for last operation to be completed */ status = FLASH_WaitForLastOperation(); if(status == FLASH_COMPLETE) { /* if the previous operation is completed, proceed to program the new data */ FLASH->CR &= CR_PSIZE_MASK; FLASH->CR |= FLASH_PSIZE_WORD; FLASH->CR |= FLASH_CR_PG; *(__IO uint32_t*)Address = Data; /* Wait for last operation to be completed */ status = FLASH_WaitForLastOperation(); /* if the program operation is completed, disable the PG Bit */ FLASH->CR &= (~FLASH_CR_PG); } /* Return the Program Status */ return status; } static void flashPage(vo

Hi everyone,I have written class that handles U(S)ART communication on top of HAL. In my application I have several objects of that class, e.g. one for USART2, another for LPUART1,...Currently, I have my own way of registering callbacks: I have static method that stores, which UART handle (UART_HandleTypeDef) belongs to which of my object. The callback function then looks up what object is responsible for the handle passed to it. E.g.:  void HAL_UARTEx_RxEventCallback(UART_HandleTypeDef *huart, uint16_t Size) { UartComm* uc = UartComm::get_object_by_UART_Handle(huart); if (uc == nullptr) { return; } uc->RxEventCallback_(Size); }   If understand correctly, the HAL provides HAL_*_RegisterCallback, which would allow a similar registration directly. Having "ordinary" functions this should be straight forward but in my case I would need binding to an object method.Is there a clean / preferred way of doing so? Or better stick with the current solution :\I am

Hi all, i decided to write a simple program on my stm32 board (B-L475E-IOT01A), here are some of the setting of my peripheral: i read input data from channel 2 sampling data on rising edge   The clock frequency at which the microphone is outputting PDM bits is 80 Mhz (by clock tree) divided by 40 using the internal prescalerfor the filtering on pdm signal i choose (by using the table) sinc3 with FOSR = 32, so that my output data is represented on a 16 bit signed integer.the dma mode is circular and i use one bufffer for dma and the other buffer for pcm samples, the samples are mono so the audio buffer contains only one channel sampleshere is a snippet of my code, i didnt include half buffer and full buffer callbacks, they just update the associated flags.  The problem with this program is that, the audio buf data is always negative (which i suppose is wrong because we are talking about some pcm waveform). What am i doing wrong?

     I am using an STM32 Nucleo H563ZI board for stm32CubeIDE and I am trying to send AT commands to a Telit LE910C4-WWX threadx modem over usb using the usbx host and threadx middleware. My program should be able to detect the modem as a cdc acm device, but it's failing to enumerate. When I connect a usb mouse to the Nucleo, it can enumerate properly as an hid mouse, which leads me to believe that the modem might not be properly configured. When I connect the modem with the configuration AT#USBCFG=1, it steps through the _ux_host_class_cdc_acm_entry() function 7 times, and the last time, it is able to check for IAD presence, but the IAD class is 2, and the IAD subclass is 0, so it still fails. Is there some other configuration for the modem I need to do, or do I need to modify the usbx driver or the ioc file?

Hi,I have an STM32L412RBT6P microcontroller and a CFAG12864T3-NFH LCD which uses an ST7565 controller. I want to use SPI to communicate with the LCD and leverage DMA to efficiently transfer data with lowest current consumption possible. Could someone provide an example code or any helping notes on how to set this up? Specifically, I'm looking for:1. Initializing the SPI peripheral on the STM32L412RBT6P for communication with the ST7565 controller.2. Configuring DMA to handle data transfers from memory to the SPI peripheral.3. Sending initialization commands and data to the LCD with ST7565.Any help would be greatly appreciated!

I have a high-resolution timer configured at some frequency. This master timer has three other timers associated to it, where each timer also runs at the same frequency. But the trigger events of these timers are compare values from the master timer, that generate update event to trigger the reset of these timers.This works and all and I am using LL APIs but I need now at some point to change the period of these timers to a lower frequency. I know I can change the period using LL APIs while running. But can I do so without causing any glitches?I have 6 outputs (2 for each timer) set to 50% duty cycle.My approach would be to use the functions as follows, but instead of doing a jump in the period, I do in a ramped fashion. Which means each run of the mainLoop I changed the period and then apply the code shown for all timers.Then after 10 mainLoop runs, the change of frequency is completedLL_HRTIM_TIM_SetPeriod(HRTIM1, LL_HRTIM_TIMER_MASTER, NEW_PERIOD); LL_HRTIM_TIM_SetPeriod(HRTIM1, LL_
