我正在尝试设置一个读取canbus数据输出的车载PC。我希望计算机自动设置usb2serial设备。
我的问题是来自SocketCAN的命令:
sudo ip link set up can0 type can bitrate 125000
我无法使连接正常工作。
在终端中执行命令时,它会提示链接成功,但是当go代码运行时,它仅返回can't find script fork/exec
func Can_connect() error {
var err error
if helpers.Can_bitrate == 0 {
log.Println("can bitrate = 0")
err = errors.New("can bitrate = 0")
return err
}
//sudo ip link set up can0 type can bitrate 125000
obd_connect := exec.Command("bash", "-c", "sudo ip link set up can0 type can bitrate "+string(helpers.Can_bitrate))
obd_connect.Run()
obd_output, err := obd_connect.Output()
if err != nil {
log.Println("Error reading output from connecting to obd", err)
return err
}
i, err := strconv.Atoi(string(obd_output[:len(obd_output)-1]))
if err != nil {
log.Println(err)
}
if i == 0 {
log.Println("successful confection to obd")
} else {
log.Println("unable to setup obd")
}
return nil
}
