STM32 MCUs Products

Hi Finding the time difference between signals in microphones.

I am currently trying to use a stm32F767ZI to find the phase difference between a sound wave using three microphones. My plan is to use the three ADCs withDMA in simultanously mode to achieve high enough sampling time. My question is how to find the ...

I am using STM32F070F6P6 with my own board, and I have the following issue: When I start debug session in Keil run button is something like already pressed and when I stop the execution the PC is at address 0x1FFFCAC4. The program never enter main.

I use Cube MX to configure pins and peripherals.I think that is board issue but I can't find the reason.Thanks

How can we integrate continuous data(Real time data)

Hello.I am estimating SOC using coulomb counting method.By coulomb counting method ,we have to do integration of discharge current.I got successfully discharge current in a variable but it shows one value at a time.I know,by using array we can store ...

STM32F417 RTC_BKPXR Reset during power up

The RTC_BKPXR register is for recording power off status in our board, we make 10 boards, 4 boards works and 6 boards keep reset the RTC_BKPXR during power recycle, I check the Vbat, it is 2.91 Volt after power off which is correct.I use TureStudio t...

How to use internal rtc of stm32fo microcontrollers with out delay in time.

I have been using internal rtc of stm 32 microcontroller for which i have connected external 32.768khz crystal with out load capacitors i have recording the values since three days and i have observed inaccurate time which is 43 sec faster, i was con...

Where can I download the Flash Loader sources from the STM32F7xx_QSPI.FLM (Keil uVision) to change the GPIO Pins? We want to integrate the Micron MT25QL512 Flash from the STM32F7x6_Eval Board into our circuit.

STM32 UART Baremetal

Hey guys, I've been playing around with STM32F334R8 Nucleo board's USART module. As a part of it, I have written a small bare-metal code to print a character and unfortunately, my code isn't working. I am seeing junk on my putty window sometimes and ...

STM32H745-DISCO odd SDRAM problem

Hi all,my SDRAM setup seems to work EXCEPT that I have a strange behavior:When I write any value (8, 16, 32 bit) to an address (example 0xd000004),it in fact gets written to the address - 2, in this example 0xd0000002.All written bytes are readably @...
