stm32---gpio-EEWORLD

Collect

This program is a small entry-level program, equivalent to hello world in C language! I hope it will be helpful to you. I try to write this program as simple as possible!

The program is written using library functions and does not directly operate registers.

Library version STM32F10x_StdPeriph_Lib_V3.5.0, development environment MDK4.12, debugging tool is JLINK v8.0, chip STM32F103C8T6

Note: If you use the 3.5 library for development, the configuration of RCC is much simpler. The system calls the SystemInit() function by default to automatically initialize the clock. You only need to enable the corresponding GPIO port.

[cpp] view plain copy

#include "stm32f10x.h"
//Define the GPIO structure
GPIO_InitTypeDef GPIO_InitStructure;
//main function
int main()
{
// Enable GPIO clock
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
//GPIO structure configuration
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
//GPIO initialization
GPIO_Init(GPIOB, &GPIO_InitStructure);
// Turn on the small light
GPIO_SetBits(GPIOB, GPIO_Pin_5);
//Infinite loop
while(1);
}

Difference between STM32 core reset and system reset and program implementation

1. Preface Some systems allow reset, but have special requirements for peripherals: a certain IO state cannot be changed due to reset, a certain timer counter cannot be changed, etc. For example: System A controls the power of system B through an IO, and the power of system B is turned on only when this IO is set high

stm32 startup process

In the current embedded application development process, C language has become the best choice for most occasions. In this way, the main function seems to be the starting point for granted - because C programs often start execution from the main function. But a question that is often overlooked is: how does the microc

Analysis of TCP/IP protocol stack code UDP (STM32 platform)

1. Introduction to UDP UDP is a simple datagram-oriented transport layer protocol: each output operation of a process generates exactly one UDP datagram, which is assembled into an IP datagram to be sent. This is different from stream-oriented protocols such as TCP, where the entire data generated by the application

STM32_GPIO key input

/* Name: STM32_GPIO key input Note: This experiment is about the input function of GPIO. The basic idea is similar to that of 51 single-chip microcomputer. Operate the corresponding IO port, but the difference is that for the independent key input experiment, the 51 microcontroller is It is necessary to set the IO

Things about STM32's independent watchdog

Why does the MCU have a watchdog? With this question, let's learn about the watchdog. Even the 51 microcontroller has a watchdog, which shows that this dog is very important to us. The purpose of the watchdog is to prevent the program from running wildly. The operation of the MCU program will be disturbed in differe
