STM32 MCUs Products

In STM32F303RE my customer is trying to use 3 timers but problem is happening with using them at the same time as it is real time application

I am using TIM1&TIM8 for PWM generation and using TIM15 for PWM input capture mode, individually if I check in IAR TIM1&TIM8 WORK properly for PWM generation, and TIM15 properly in input capture mode, but if I use them all together after the first it...

Hello. I need to development a project that only count pulse of a flow meter. But i need count this pulse with a ultra low power, because I using battery without solar panel. What the best option of Microcontroller ST, and using timers I can do that?

About 100 micro amps is greatfull. Sorry, I'am begginer. Thank you.

How to interface WS2813 LED strip to STM32F413ZH development board

I have an STM32F413 disco board and now I have to interface WS2813 LED strip to the controller board.I found a sample code for nucleo board but I didn't understand how they interfaced to the board.I ported their code to our controller board but I am ...

Write issue with STM32F405 w/ SDIO using fatfs as part of CubeIDE. uSD card mounts OK, system links OK, but anytime a write operation occurs there is a fault. The hardware has been instrumented OK and checked withe same result on another PCB.

However this was tried on an STM32F469 Discovery and worked fine. Does anyone have an STM32F405 running with an SD using a fatfs?

QUADSPI, hammered by FTF interrupts as soon as I set CR?

Hello, so I am creating a QUADSPI driver to interface with some external FLASH, and what I've discovered is that as soon as I set my QUADSPI_CR register, I am spammed by FIFO threshold interrupt (FTF) interrupts. I guess this makes sense, because my ...

ethernet communnication with STM32h7 NUCLEO cubemx and keil

I use stm32h7 microcontroller and I want to make ethernet communication cubemx and keil .However I didn't find resources or examples.

TOO Many loads!!!

What is the best way to make work-like prototype?

My project is to build a battery operated you've got mail detector (which detects if there is mail inside the mailbox with TOF sensor with RF notification. Which would be the preffered way to build this proof of concept? Nucleo + Shields? Disco + Shi...

ADC triggers only in rising edge PWM

Hi! ADC triggers only on rising edge of PWM signal. I want to trigger it at both rising/falling​ edge. When ADC=continous conversions, I can see some samples are 3V some 0V. But its random. So I changed continous conversions=disable.​Using HAL.​​Pwm ...

Does STM32H743 mcu support ONFI1.0?

I am going to use STM32H743 mcu.​And I am trying to configure the nand-flash memory test circuit using this chip (using the EVL board).What I want to ask is whether you can use nand-flash memory chip that supports only ONFI1.0 as STM32H743 chip.​Than...
