Arduino在上传代码时更改了COM端口（Windows）

Question

我正在Windows中测试新的MKR1000。我有一个恼人的问题，导致Windows每次将新代码上传到开发板时都会在另一个端口中重新安装Arduino驱动程序。例如： -

如果安装在COM4 Arduino的，当我上传的代码插入到主板的Windows决定在COM5安装Arduino的。这会导致IDE告诉我上传过程失败（因为COM5上没有连接Arduino），但奇怪的是，代码实际上传正确。

如果我想打开串口监视器，我需要进入IDE并将Arduino端口改回COM4。每次将新代码上传到Arduino时，让Windows通过驱动程序安装过程是非常烦人的。

一些通用的信息：

• 这发生在这两个Windows 7
• 我与闪烁例如故障排除（引脚6）
• 的问题，同时与Arduino的IDE发生（1.6 0.11）&的Arduino创建（1.0.38）
• 的MKR1000正确安装在Windows中，显示在设备管理器 '的Arduino MKR1000（COM4）'
起来SAMD板1.6.6安装
• 试过多个USB电缆

在Arduino的IDE的错误是：

Answer 1

是的，我也有同样的问题。尝试下载arduino advance ide（增强版）。

Here

这应该帮助，因为当它改变端口，它会告诉你，问你，如果你想。

希望它有帮助！
