STM32L4+USART+Rx+HAL-------Distortion of received data

Hello Everyone,I am using Nucleo-32 board in my project. I am programming USART to receive 10 character data and then transmit this 10 character data back. Problem that I am observing is that if accidentally 11 character it is suppose to display erro...

Find MCU by supported Debug/Trace facility

Do Interrupt Priorities Have To Start At Zero?

I've been fighting a very subtle strange QSPI bug for a while now where data is occasionally spuriously clocked out unexpectedly. Without going into too much detail about that right now, my question is about interrupt priorities. I found what appears...

Question on Floating Point operations

I've heard that floating point operations are very time consuming. However, I've seen that many STM32 include a floating point unit. I'm using a L432KC Nucleo. How does it exactly work? As far as I know, L432KC includes this unit which supports hardw...

I used stm32cubemx to config stm32f407, when it entry stop mode, PA0 is used to wakeup MCU from stop mode, how to config system clk. when it entry into stop mode and leave stop mode

entry into stop mode:  HAL_NVIC_EnableIRQ(EXTI0_IRQn);  HAL_PWR_DisableWakeUpPin(PWR_WAKEUP_PIN1); __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WU);  HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1);  __enable_irq(); HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_ST...
