- 引入 go-serial 库
go get github.com/jacobsa/go-serial/serial
- 编写串口读取函数
func readFromPort(port io.ReadWriteCloser) {buf := make([]byte, 1024)for {n, err := port.Read(buf)if err != nil {log.Fatal(err)}fmt.Print(string(buf[:n]))}}
- 打开串口
port, err := serial.Open(serial.OpenOptions{PortName: "COM1",BaudRate: 115200,DataBits: 8,StopBits: 1,MinimumReadSize: 4,})if err != nil {log.Fatal(err)}defer port.Close()
- 向串口写入数据
_, err = port.Write([]byte("hello"))if err != nil {log.Fatal(err)}
完整代码：
package mainimport ("fmt""io""log""github.com/jacobsa/go-serial/serial")func readFromPort(port io.ReadWriteCloser) {buf := make([]byte, 1024)for {n, err := port.Read(buf)if err != nil {log.Fatal(err)}fmt.Print(string(buf[:n]))}}func main() {// 打开串口port, err := serial.Open(serial.OpenOptions{PortName: "COM1",BaudRate: 115200,DataBits: 8,StopBits: 1,MinimumReadSize: 4,})if err != nil {log.Fatal(err)}defer port.Close()// 开启读取协程go readFromPort(port)// 写入数据到串口_, err = port.Write([]byte("hello"))if err != nil {log.Fatal(err)}// 等待select {}}
