Question

Windows 10，Arduino Micro。我最初使用的是标准的“ Blink.js”教程，但是Johnny-Five一直连接到错误的串行端口。我对我的COM端口（在本例中为端口8）进行了硬编码，并且超过了最初的错误，但是新的错误使我死了。我的输出看起来像这样：

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;
    ^

我已经完成了他们建议的所有显而易见的操作：重新刷新固件，刻录引导程序，重新安装节点和npm，逐步完成Arduino的安装说明，尽管我必须这样做通过Windows而不是命令行来推送standardFirmataPlus.ino，因为Windows本身并不包含用于Arduino的命令行工具。我的代码（如果有什么不同）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);
});

我一直在努力争取使用Johnny-Five来获得Arduino的任何反应，我们将不胜感激。

Answer 1

事实证明，问题在于交叉兼容性问题。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软件包不同，serialport是特定于平台的软件包。因此，学习使用gitignore。

希望这对其他人有帮助。
