STM32 MCUs Products

Dear All I already informed you that I already have the STM32H735G-DK tools for the New STM32H72x/3x MCUs for running deeply embedded applications Online workshop information my email : d.frigerio@loptex.it

Facing difficulty to access internal bootloader in STM32H743BIT6

Hi Guys,I working on one project where we need to enter into system bootloader for updating new firmware through the UART from software without using BOOT0 Pin.But I am facing problem in entering bootloader through software(user application).I had c...

Write Backupcode from QSPi to SDRAM when flashing from IDE

My application is executed from flash and external SDRAM.I have a bootloader(seperat project) that saves the volatile SDRAM content on a QSPI.Normaly my application is applyed by a .hex file that is located on the SD-Card. So my bootloader can clearl...

STM32H753 ADC auto calibration not working properly?

I am using STM32H753 MCU. I am using ADC1 and ADC2 and calibrated the ADC offset using auto calibration function. But this function is not working properly. I am getting a difference of 50 counts on subsequent starts of my device. I checked this by g...

Errors in STM32F446RE datasheet

Refer to https://www.st.com/resource/en/datasheet/stm32f446re.pdfIn section 3.23 on PDF page 32, it says:"The devices embed four universal synchronous/asynchronous receiver transmitters (USART1, USART2, USART3 and USART6) and four universal asynchron...

Enable conversion of regular group is crashing / resetting program.

Howdythis line: hadc->Instance->CR |= ADC_CR_ADSTART;at the end of: HAL_ADC_Start_DMA(ADC_HandleTypeDef* hadc, uint32_t* pData, uint32_t Length);is causing a crash / reset. I've used HAL for this set up quite a few times with no problems, but this ti...

Delay function using timers - LED blinks too fast

void delay_setup(void) { rcc_periph_clock_enable(RCC_TIM6); timer_set_prescaler(TIM6, rcc_apb1_frequency / 1000000 - 1); timer_set_period(TIM6, 0xffff); timer_one_shot_mode(TIM6); }   void delay_us(uint32_t us) { TIM_ARR(TIM6) = us; TIM_EGR(TIM...

using STM32L0538, is it possible to make SysTick_Handler count in microseconds not in milliseconds and if it is, where to start?

I'm writing some code with PWM and I'm using very high number of periods in short time causing my LED's to dim very choppy. I think it's not working properly because timer is to fast and counting in milliseconds and I need it to count in microseconds...
