Question

我正在尝试使用johnny-five模块在Windows 8.1和Node.js的USB上的esp8266上运行simled led闪烁。

我已经按照本教程https://boneskull.com/how-to-use-an-esp8266-with-johnny-five/进行操作，并且能够通过wifi连接执行所需的任务。

从Arduino IDE上传StandardFirmataWifi示例后，此代码将起作用：

const { EtherPortClient } = require('etherport-client');
const five = require('johnny-five');

const board = new five.Board({
    port: new EtherPortClient({
        host: '192.168.1.113',
        port: 3030
    })
});

board.on('ready', () => {
    var led = new five.Led(2);

    // "blink" the led in 500ms
    // on-off phase periods
    led.blink(500);
});

但是，当我尝试使用usb连接而不是wifi使用以下代码运行相同的代码时：

const { EtherPortClient } = require('etherport-client');
const five = require('johnny-five');

const board = new five.Board();

board.on('ready', () => {
    var led = new five.Led(2);

    // "blink" the led in 500ms
    // on-off phase periods
    led.blink(500);
});

它输出下一个错误：

Please check that you've properly flashed the board with the correct firmware.

ng

If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the b
oard, wait approximately 11 seconds for complete reset, then run your program ag
ain.

PS：当我通过USB从Arduino IDE加载草图时，它可以完美工作，所以我认为问题在于某些节点配置。

在此先感谢您的帮助！
