STM32 MCUs Products

Hi, I am trying to connect ESP8266 module to STM32F429ZI so I am wondering if (and which) transmit pins of UART transmit max voltage of 3.3V (not 5V)? Thanks in advance!

Hello. When I use external crystals, I have a low frequency (2Hz) disturbance on PWM outputs. This disturbance also appear on SWDIO & SWCLK pins. But everything is ok with internal oscillator. The MCU is STM32f401RBT6. Thank you for your help.

The first image is PWM output when using internal oscillator & The second image is PWM output when using external crystal.

Hardfault (Usage Fault INVSTATE) on STM32H743 - how can I find the position where the fault happened?

I have a system with several SPIs and logging of data to SD Card. During a test which logged data over night the system ran into a Hard Fault (INVSTATE) after some hours. My questions:What is the reason for an INVSTATE Hard Fault? How can I detect, ...

Issue with microseconds delay with timer

Hi,we are using stm32f745xx and bellow are our configurations.we are using total 6 timers, out of which we are using TIM6 to generate 50us interrupt.htim6.Instance = TIM6;htim6.Init.Prescaler = 1;htim6.Init.CounterMode = TIM_COUNTERMODE_UP;htim6.Init...
