Instructions for using STM32 SysTick delay

/*Initialize clock*/ void Init_SysTick(void) { if(SysTick_Config(SystemCoreClock / 1000)) //Note: SystemFrequency is replaced by SystemCoreClock in the 3.5 library. while(1); } /*1ms delay function*/ __IO uint32_t TimingDelay; void delay_ms(__IO uint32_t nTime) { TimingDelay = nTime; while(Timi

Detailed explanation of STM32's gpio mode set

When I was reading the data sheet recently, I found that there are 8 types of GPIO configurations in Cortex-M3: (1) GPIO_Mode_AIN analog input (2) GPIO_Mode_IN_FLOATING floating input (3) GPIO_Mode_IPD pull-down input (4) GPIO_Mode_IPU pull-up input (5) GPIO_Mode_Out_OD open-drain output (6) GPIO_Mode_Out_PP push-p

STM32 serial port ring buffer

1 Overview 1.1: This article implements the serial port driver, realizes the redirection of the printf function, realizes the interrupt reception and transmission of the serial port, and imitates the 3.5T timeout mechanism in the modbus protocol to determine whether the reception is completed; 1.2: If the serial p

stm32 learning notes (1): real-time clock RTC

I haven’t written a decent article for a long time. I will start with my study notes and then gradually supplement my microcontroller study notes from this month. -------------------------------------I am the dividing line you can't see------------------------------------------ 1.

STM32 interrupts and nested NVIC quick start

A quick introduction to STM32 interrupts and nested NVIC. I also learned it by reading this book: Cortex-M3 Definitive Guide by Joseph Yiu Translated by Song Yan It’s actually very simple. //CM3 has up to 240 interrupts (usually external interrupts are written as IRQs), which is what the software calls IRQ CHANAE

STM32ADC sampling time, sampling period, sampling frequency calculation method

ADC conversion is the conversion of analog input signals into digital signals by the microcontroller. To read the digital signal, you must wait until the conversion is completed. The completion of a channel reading is called the sampling cycle. Generally speaking, the sampling cycle = conversion time + reading time.
