Windows 10,Arduino 微型。我最初使用的是标准的“Blink.js”教程,但 Johnny-Five 一直连接到错误的串行端口。我硬编码了我的 COM 端口(在这种情况下为端口 8),并克服了最初的错误,但一个新的错误阻止了我的死亡。我的输出如下所示:

C:\Users\...\folder>node Blink.js
1536475383667 Connected COM 8
1536475383673 Error Opening COM 8: File not found
(node:12700) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Uncaught, unspecified "error" event. ([object Object])
1536475393671 Device or Firmware Error A timeout occurred while connecting to the Board.

    Please check that you've properly flashed the board with the correct firmware.
    See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting

If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the board, wait approximately 11 seconds for complete reset, then run your program again.
events.js:165
    throw err;
    ^

我已经完成了他们推荐的所有明显的事情:重新刷新固件,烧录引导程序,重新安装节点和 npm,逐步完成了 Arduino 的安装说明,尽管我不得不推送标准的FirmataPlus .ino 通过 GUI 而不是命令行,因为 Windows 本身不包含用于 Arduino 的命令行工具。我的代码,如果有什么不同的话,看起来像这样:

var five = require("johnny-five"),
    board, led;

board = new five.Board({port: "COM 8"});

board.on("ready", function() {
  console.log('ready');
  led = new five.Led(8);    //This would be port 13 on most, but the Micro doesn't have that port
  led.strobe(100);
});

多年来,我一直在努力从使用 Johnny-Five 的 Arduino 获得任何反应,任何帮助将不胜感激。

事实证明,问题是交叉兼容性问题。我使用 Git 在计算机之间同步文件和项目,一台计算机是 Mac,另一台是 Windows。与许多其他 JavaScript 包不同,serialport 是一个特定于平台的包。所以,学习使用 gitignore。

希望这对其他人有所帮助。
