上传代码时Arduino更改COM端口(Windows)
上传代码时Arduino更改COM端口(Windows)
提问于 2016-09-13 22:04:12
我正在Windows中测试新的MKR1000。我有一个恼人的问题，导致Windows重新安装在另一个端口的Arduino驱动程序，每次我上传新代码到板。例如：
如果Arduino安装在COM4上，当我将代码上传到板上时，Windows决定在COM5上安装Arduino。这导致IDE告诉我上传过程失败(因为COM5上没有连接到Arduino )，但奇怪的是，代码实际上正确上传。
如果我想打开串行监视器，我需要进入IDE并将Arduino端口更改为COM4。每当我将新代码上传到Arduino中时，让Windows通过驱动程序安装过程是非常烦人的。
一些一般性信息：
- 这在Windows 7和8中都会发生
- 我正在用Blink示例进行故障排除(pin 6)
- 这些问题发生在Arduino IDE (1.6.11)和Arduino Create (1.0.38)中。
- MKR1000在Windows中正确安装，在设备管理器中显示为'Arduino MKR1000 (COM4)‘
- 安装了SAMD板1.6.6
- 试用多个USB电缆
Arduino IDE中的错误是：
Arduino: 1.6.11 (Windows 7), Board: "Arduino/Genuino MKR1000"
Sketch uses 7,972 bytes (3%) of program storage space. Maximum is 262,144 bytes.

嗨，基于您的输出，可能有一个原因，它这样做。如果我错了，其他开发人员可以纠正我。
当您将代码上载到ATSAMD21时，
->所使用的IDE/开发环境将使板进入引导加载程序模式5秒。( 1200bps) //步骤1
->但当它将程序上传到板时，引导加载程序在成功上传后锁定，并更改其端口//步骤2
->在步骤1中，微操作为本地USB端口，并调用编程USB端口
->在步骤2中，微程序完成编程，并在重置后返回其默认状态--原生USB端口(这是COM端口更改到下一个端口的地方)。
希望能帮上忙。

这是我对SAM操作失败的修正。使用USB3端口的情景Windows 7(以前只使用USB2端口的Windows 7机器)上传到Sparkfun
将USB 2集线器放在PC机和电路板之间。
SAM-BA错误不再发生。
