# Serial

Serial 是一个Go语言实现的串口(Uart)接口包,可使用操作系统标准的 read 和 write 文件接口

实现串口字节流的接收和发送。

## 默认配置

 

> 8 N 1 N （数据位: 8 奇偶校验: N 停止位: 1 数据流控: N）

## 代码使用

```go

package main

import (

	"log"

	"github.com/xluohome/serial"

)

func main() {

	c := &serial.Config{Name: "COM9", Baud: 9600}

	s, err := serial.OpenPort(c)

	if err != nil {

		log.Fatal(err)

	}

	txbuf := []byte{0xAA, 0x01, 0x0f, 0x00, 0x00, 0xBA}

	n, err := s.Write(txbuf)

	if err != nil {

		log.Fatal(err)

	}

	buf := make([]byte, 128)

	n, err = s.Read(buf)

	if err != nil {

		log.Fatal(err)

	}

	log.Printf("%X\n", buf[:n])

}

```

## 非阻塞模式

By default the returned Port reads in blocking mode. Which means

`Read()` will block until at least one byte is returned. If that's not

what you want, specify a positive ReadTimeout and the Read() will

timeout returning 0 bytes if no bytes are read.  Please note that this

is the total timeout the read operation will wait and not the interval

timeout between two bytes.

```go

	c := &serial.Config{Name: "COM45", Baud: 115200, ReadTimeout: time.Second * 5}

	

	// In this mode, you will want to suppress error for read

	// as 0 bytes return EOF error on Linux / POSIX

	n, _ = s.Read(buf)

```
