STM32 MCUs Products

hi, i am new to stm32, i am doing a project on fan controller module, i need to measure the powerfactor of zero crossing of my current and voltage waveform displaying on CRO. firstly i need to select two channels for input capture to capture values

on those rising edge with interrupt and i need to count each time.secondly i need to use another timer and set its frequency to 100KHZ with interrupt mode. i need to use counter to count at each interrupt. thirdly based on that counter i need to cal...

STM32H725 ADC3 circular DMA not working? (It does with ADC1)

I've been stumbled upon this issue for a week now.On STM32H725ZG, ADC3 circular DMA is not working.A test codelet below, designed to demonstrate the issue, repeatedly takes 12-bit readings from PC0 (ADC123_INP10) and PC1 (ADC123_INP11) with ADC1 or A...

Hi , I would like to know if there is a way to use DMA to get the TIM1 advanced timer update events ? I can successfully trigger an IRQ but having problems setting a DMA to trigger on every update. I am using STM32 L4 MCU.

I am using the advanced timer TIM1 on STM32L476RG MCU. I have configured the timer in slave reset mode as given in section 30.3.26 of the reference manual. The counter resets every rising edge. I want to use this mode to measure low frequencies such ...

Hi, i would like to know which chip is under name ST A267BB (100 pin case ).

Low power modes on STM32L4 series MCU

Hi, Below is my requirement: Need to send a DAC sample every 2ms (on 32KHZ clock) Every 12 sec will do an access to external flash to copy a block of memory (on HSI clock)how can i accomplish this? am new to microcontroller, can anyone help me with s...

DWT_CYCCNT does not seems to count cycle

I'm using follow code:volatile unsigned int *DWT_CYCCNT = (volatile unsigned int *)0xE0001004; //address of the register volatile unsigned int *DWT_CONTROL = (volatile unsigned int *)0xE0001000; //address of the register volatile unsigned int *DWT_L...

Run Debugger in one step

hi I want to enter the debugger mode and then run the whole code by clicking 'Run' button or F5. but every time that I click 'Run' it just goes one step forward and it even enters inner functions...what should I do?

i need to create the motor profile of 86BLF03 WITH x-nucleo ihm08m1 AND nucleo f303re

i am trying to create 86BLF03 motor profile using X-NUCLEO IHM08M1 AND NUCLEO F303RE boards, i am having serious problems cause i can't find max current, vbus, magnetic.Moreover X-NUCLEO IHM08M doesn't give me any information about the phase of the c...
