STM32 MCUs Embedded software

i try to implement stm32f10c example on a custom board with stm32f107 as my controller but it causing the controller to always goes in to hard fault please suggest what to do

Hi guys, Ill keep this short, anytime I set the I2S bus to use FWS = 196KHz it acts all whack.I am not sure if its the tool I am measuring with but its a saleae logic analyzer so I doubt it. Here a picture of what I am talking aboutI double checked everything the clock config is correct, I double checked with other FWS work such as 96,48, and 44.1 KHz and they are all fineThe GPIOs are using the "Very High Speed" Setting as wellCode/* * AUDIO_SELECTOR_FACTORY.c * * Created on: May 3, 2021 * Author: Christopher */   #include <CONSTANTS.h> #include "stm32h753xx.h" #include "Opcode.h"   void INPUT_AUDIO_SELECTOR (int INPUT_TYPE, int BIT_RATE, int SAMPLING_RATE) { RCC->APB2ENR |= (RCC_APB2ENR_SPI1EN);   //DECONFIG I2S DMA1_Stream0->CR &= ~DMA_SxCR_EN; DMA1_Stream1->CR &= ~DMA_SxCR_EN; SPI1->CR1 &= ~SPI_CR1_SPE; SPI1->CR1 &= ~SPI_CR1_CSTART; RCC -> CR &= ~(RCC_CR_PLL2ON);   //CONFIG I2S   switch (SAMPLING_RAT

Hello everybody,I am currently using a stm32l4R9 and it's communicating with a RTL2832u over USB FS. The initialisation works perfectly (using USBH_CtlReq). However, when I use USBH_BulkReceiveData I can see a frame transmitted on my oscilloscope but the STM32l4 doesn't get it and USBH_LL_GetURBState returns ERROR after a while (5ms approx)I really need help with this because it's been weeks and still I have the same bug.Thanks in advance,

Hi,For one project i have to save some pictures taken with one SPI Camera into an SD Card by SPI and i have to save also some info related to the image. For saving the pictures i am going to use FATFS and i was wondering if i could save some Exif info along with the picture. Otherwise i would have to create another file on the SD and link it to the picture. Thanks in advance.

I am trying to interface DS18B20 (Temperature Sensor) with STM32L072 using OneWire communication. But not able to generate proper delay.I have reached some of the solutions but did't worked.https://community.st.com/s/question/0D53W000003LJZsSAO/micro-sec-delay-with-stm32l0This solution uses UART and custom HAL, that I cannot use.https://community.st.com/s/question/0D53W00000UiUVjSAN/interfacing-ds18b20-temperature-sensor-with-stm32wb55-development-boardPlease Help If any one have better solution

void DMA_DoubleBufferModeConfig(DMA_Stream_TypeDef* DMAy_Streamx, uint32_t Memory1BaseAddr, uint32_t DMA_CurrentMemory)What is your role?

I am working on a project that requires 3 channels of ADC1 and FreeRTOS.I am using STM32F446RCT6. I start ADC conversion at the start of the code HAL_ADC_Start_IT(&hadc1);Here is my implementation for ADC callback.whereas array to hold data is described as: volatile uint16_t ADC_raw[3] = {0};void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { if (__HAL_ADC_GET_FLAG(hadc, ADC_FLAG_EOC)) //if call to end of convesion { ADC_raw[counter] = HAL_ADC_GetValue(hadc); //ADC value stores in array counter++; if(counter>2) counter = 0; }   }Now, When I do not implement RTOS and just runs normal code in while(1) loop, it works well and values for ADC_raw is updated correctly.But when I enable RTOS and run the same code, the ADC callback is never getting called and thus ADC_raw values are always zero.I can't figure out what can be the issue. Any help would be greatly appreciated.Here is my configuration for ADC, interrupt is enabled, DMA is not used. Here is my RT

I'm using STM32H745. Both cores run FreeRTOS 10.2.1. Timebase for CM4 is TIM6, and CM7 is TIM7. For some reason, on CM4, from the time osKernelStart() is called in main() until StartDefaultTask starts to run is about 5 seconds ( i turn an LED on just before osKernelStart() and it's turned off first thing in StartDefaultTask) . The only reason i can think of is that the timebase/tick interrupt don't get going for that amount of time. Other than this startup behavior, CM4 multi tasking seems to be fine. Has anyone seen this?

Hello guys,I have a small question I have st link v2.1 which comes with the Nucleo board, so I need to program another custom board using this st link, but I have to do using UART (Rx, Tx) pins which is nearby the SWD connector, please if anyone has an idea about please let me know. I used cube programmer and tried to connect with UART but it is giving an error that saying Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... Used the flash Loader as well but it is not connecting, wiring wasStlink Rx ---> MCU Tx (PA2)Stlink Tx ----> MCU Rx (PA3)BOOT0 --- HighNRST ----> NRSTIf there is any other error can you point it to me?

Hi,I have STM32F030 which is connected to STM32L082 with UART (Rx/Tx), RESET and BOOT0 line. When needed STM32F030 is able to restart STM32L082, run ROM Bootloader, erase and program flash.But when I have clean STM32L082, empty flash on it on production, STM32F030 has a problem with restart and run main program for STM32L082. To run it, it needs power reset.I've read about OBL_LAUNCH, but it does not work.I try to:write value 0x89ABCDEF to 0x4002200C address FLASH_PEKEYRwrite value 0x02030405 to 0x4002200C address FLASH_PEKEYRwrite OBL_LAUNCH to 0x40022004 - address FLASH_PECRAnd I got NACK in 1st command for setting 0x4002200C address.And my question, does Bootloader (ST ROM) have access to these addresses ? BRJakub

So I notice when I configure my STM32F769 Discovery board as USB Host, the generated middleware already have built in logging USBH_UsrLog() which is handy.But looking at it definition on the macro, basically it wrap standard printf() like following:#define USBH_UsrLog(...) do { \ printf(__VA_ARGS__); \ printf("\n"); \ } while (0)I am not sure the original intention of making it printf(), but let say I want to direct this into Virtual Com Port, how should I do this? Without doing anything, let say I already define my USBH_DEBUG_LEVEL > 0, can I see the USB logging somewhere?

I have seen a similar thread for the ST25R3916-DISCO (making appropiate changes in stm32l4xx_hal_msp.c ), however in this board the USB pins are not connected to the same pins and I am not capable of correctly reconnect the solution to PA11, PA12.UART communication to UART3 (STLINK) works fine.What am I missing? Thanks in advance

@Ons KOOLI​. ​Hi, i want to use stm32f103 or stm32f1 family microcontroller for mass storage in usb for data logging.any reference and example are pretty useful as i am new to usb logging with stm32.​

HiI am trying to implement a fault filter for the HRTIM on a stm32G474.I am using the LL libraries and the Reference manual.I find the table 234 in the reference manual completely unreadable and confusing. Could someone please explain how it is suppose to be interpreted.Lets take an example.my Fhrtim is 170 mhz and I have done the followingLL_HRTIM_FLT_SetPrescaler(HRTIM1, LL_HRTIM_FLT_PRESCALER_DIV2);   LL_HRTIM_FLT_SetFilter(HRTIM1, LL_HRTIM_FAULT_1, LL_HRTIM_FLT_FILTER_4); How do i calcualte the filter length?Best regards Martin

Hi everybody,I am using stm32h743i-eval2 and I need to write data on an USB stick via USB HS.It configured by Stm32Cube easly and I could write data as well. But I don't know why the device is too slow. Throughput is about 1.2MBps via HS USB.Is that normal? or is there any configuration to speedup USB?this is a part of my code which may help you:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};   /** Supply configuration update enable */ HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY); /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE0);   while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) {} /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDef structure. */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI; RCC_OscInitStruct.HSISta

Hi there,Use DfuSe v3.0.6, upgrade success and click "Leave DFU mode"but mcu can't be reset/start?Thanks

I am trying to run DSP Functions like as FFT with freeRTOS which use multiple tasks.And HardFault is occurred from prvPortStartFirstTask() for calling FFT functions.So I don't have any idea what i check.. Please help me which parts I will check.. Thank you.

Hello,is there any way to set the user descriptor string on the USB CDC device?In the HAL library, I found some functions related to descriptor strings, but their type is "get" and I did not find a corresponding "set" functions.

Having a bad documentation day or something, I registered the ICCID with Truphone but after 5 hours of watching it trying to find an operator I don't think it's going to happen. No information at Truphone about carriers or network support.

I've enabled LwIP in CubeMX and now I cannot compile my code anymoreI thought the include paths where the problem, but I checked them all multiple times and I cannot find the error.   Can someone help me?

Hii all, ım using stm32f103c8t6 and trying to implement freertos project,i have flash write function and it work very well but when i use it in freertos project, if ı call write flash func before vTaskStartScheduler it is okey but after vTaskStartScheduler from any of task it gives hard fault. what can go wrongit tried tasksuspend , taskenterritical, disable_interrupt but none of them helped,any sugestions, thanx s

Hi,I have a CubeIDE peroject with STM32H753ZI, C++, TreadX, Nucleo-H753ZI board. This device has 2MB Flash and 16 sectors of 128K each. 16 x 128K = 2MB but the generated stm32h7xx_hal_flash_ex.h includes only 8 sectors. Only OB_WRP_SECTOR_0-7 are defined. Whaere is the rest?Best regards,Osto

We use STM32F479 for portable measurement device (with TouchGfX HMI, data is stored on quadspi flash also). We have a USB host interface where we can read and write data to an USB stick.Now we would like to send an USB stick to the customer in order to make an update to both flash: internal flash and external quad spi.The prefered solution would be that he inserts the usb stick, switches on the device and both the flash are overwritten by data on usb stick.Is there already a solution for this, eventually by a third party?Or is there a source which I could adapt?
