C语言实现串口通信

C语言实现串口通信

C语言实现串口通信在使用系统调用函数进行串口通信之前，需要打开串口设备并设置相关参数。

打开串口设备可以使用open(函数，设置串口参数可以使用termios结构体和tcsetattr(函数。

以下是一个简单的串口通信接收数据的示例代码：```c#include <stdio.h>#include <stdlib.h>#include <fcntl.h>#include <unistd.h>#include <termios.h>int mainint fd; // 串口设备文件描述符char buff[255]; // 存储接收到的数据int len; // 接收到的数据长度//打开串口设备fd = open("/dev/ttyS0", O_RDONLY);if (fd < 0)perror("Failed to open serial port");return -1;}//设置串口参数struct termios options;tcgetattr(fd, &options);cfsetspeed(&options, B1200); // 设置波特率为1200 tcsetattr(fd, TCSANOW, &options);//接收数据while (1)len = read(fd, buff, sizeof(buff)); // 从串口读取数据if (len > 0)buff[len] = '\0'; // 将接收到的数据转为字符串printf("Received data: %s\n", buff);}}//关闭串口设备close(fd);return 0;```这段代码首先通过open(函数打开串口设备文件"/dev/ttyS0"，然后使用tcgetattr(函数获取当前设置的串口参数，接着使用cfsetspeed(函数设置波特率为1200，最后使用tcsetattr(函数将设置好的串口参数写回。

c语言怎么写串口通信编程

c语言怎么写串口通信编程

c语言怎么写串口通信编程串口通信是一种广泛应用于嵌入式系统和电子设备之间的通信方式。

无论是嵌入式开发还是电子设备控制，串口通信都是常见的需求。

在C语言中，实现串口通信需要通过操作串口的硬件寄存器和使用相应的通信协议来实现数据的发送和接收。

本文将一步一步介绍如何使用C语言编写串口通信程序。

第一步：打开串口要开始串口通信，首先需要打开串口。

在C语言中，可以使用文件操作函数来打开串口设备。

通常，串口设备被命名为/dev/ttyS0，/dev/ttyS1等，具体名称取决于系统。

下面是一个打开串口设备的示例代码：cinclude <stdio.h>include <fcntl.h>include <termios.h>int open_serial_port(const char *port) {int fd = open(port, O_RDWR O_NOCTTYO_NDELAY);if (fd == -1) {perror("open_serial_port");return -1;}设置串口属性struct termios options;tcgetattr(fd, &options);cfmakeraw(&options);cfsetspeed(&options, B9600);tcsetattr(fd, TCSANOW, &options);return fd;}int main() {const char *port = "/dev/ttyS0";int fd = open_serial_port(port);if (fd == -1) {打开串口失败，处理错误return -1;}串口已打开，可以进行数据的读写操作return 0;}在上面的代码中，open_serial_port函数用于打开指定的串口设备并进行一些必要的设置。

stc15串口范例程序

stc15串口范例程序

stc15串口范例程序STC15是一种常见的单片机型号，它具有丰富的外设和功能，其中包括串口通信功能。

下面是一个简单的STC15串口通信的范例程序，供你参考：c.#include <STC15F2K60S2.H>。

#define FOSC 11059200L.#define BAUD 9600。

void InitUART() {。

SCON = 0x50; // 8位数据,可变波特率。

TMOD = 0x20; // 设置定时器1为模式2。

TH1 = 256 FOSC/12/32/BAUD; // 波特率9600。

TL1 = TH1; // 初始化TL1。

TR1 = 1; // 启动定时器1。

ES = 1; // 使能串口中断。

EA = 1; // 打开总中断。

}。

void UARTInterrupt() interrupt 4 {。

if (RI) {。

P0 = SBUF; // 串口接收到的数据通过P0口输出。

RI = 0; // 清零接收中断标志位。

}。

if (TI) {。

TI = 0; // 清零发送中断标志位。

}。

}。

void main() {。

InitUART(); // 初始化串口。

while (1) {。

// 主循环。

}。

}。

以上是一个简单的STC15串口通信的范例程序。

在这个程序中，我们首先定义了晶振频率和波特率，然后编写了初始化串口的函数InitUART。

在主函数main中，我们调用InitUART进行串口的初始化，然后进入一个无限循环。

当有数据通过串口接收到时，会触发串口中断UARTInterrupt，并将接收到的数据通过P0口输出。

这个程序可以作为一个基础的串口通信范例，你可以根据自己的实际需求进行修改和扩展。

希望这个范例对你有所帮助。

stm32f103串口程序代码

stm32f103串口程序代码

stm32f103串口程序代码STM32F103系列是意法半导体推出的一款32位单片机系列产品，该系列产品在嵌入式系统领域广泛应用。

其中，串口通信是单片机应用中常用的通信方式之一。

本文将介绍STM32F103的串口通信程序代码。

我们需要了解串口通信的基本原理。

串口通信是一种通过串行传输数据的通信方式，它将数据分为一系列的位依次传输。

串口通信一般包括发送和接收两个部分，发送数据时，将数据从高位到低位逐个发送；接收数据时，将数据从低位到高位逐个接收。

为了使数据传输更加稳定可靠，常常需要使用校验位进行数据的校验。

在STM32F103系列中，串口通信的实现需要使用USART模块。

USART 是一种通用的同步/异步收发器，它可以实现全双工通信。

串口通信的代码一般包括以下几个方面的内容：1. 引入头文件和定义宏：在开始编写串口通信的代码之前，我们需要引入相应的头文件，并定义一些宏。

头文件中包含了USART所需要的寄存器地址和一些相关的宏定义。

宏定义可以方便我们在代码中使用一些常用的参数。

2. 初始化USART模块：在使用USART进行串口通信之前，需要对USART模块进行初始化。

初始化的过程包括设置波特率、数据位、停止位、校验位等参数。

在STM32F103系列中，可以通过修改USART_CR1和USART_CR2寄存器来完成初始化。

3. 发送数据：发送数据时，需要将待发送的数据写入USART_DR寄存器中。

在发送数据之前，需要判断USART_SR寄存器中的状态位，确保USART_DR 寄存器为空，以免数据丢失。

发送数据完成后，可以通过判断USART_SR寄存器中的状态位，判断数据是否发送成功。

4. 接收数据：接收数据时，需要从USART_DR寄存器中读取接收到的数据。

在接收数据之前，需要判断USART_SR寄存器中的状态位，确保USART_DR 寄存器中有数据可读。

接收数据完成后，可以通过判断USART_SR寄存器中的状态位，判断数据是否接收成功。
