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

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.

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。
