问题描述
我正在尝试从TI Chronos获取加速度计数据.运行代码时收到以下错误消息:
Traceback (most recent call last):
File "C:\Python32\chronos_accel.py", line 50, in <module>
.
.
.
raise SerialException("could not open port %s: %s" % (self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port COM4: [Error 5] Access is denied.
为什么拒绝访问?我是系统管理员.代码可能有问题吗?
解决方案
我知道了.很简单.
我只是在设备管理器窗口中禁用了COM端口,然后再次启用了它. /p>
I'm trying to get accelerometer data from TI Chronos. I get the following error message when I run the code:
Traceback (most recent call last):
File "C:\Python32\chronos_accel.py", line 50, in <module>
.
.
.
raise SerialException("could not open port %s: %s" % (self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port COM4: [Error 5] Access is denied.
Why is access denied? I'm the system administrator. Could it be a problem with the code?
解决方案
I figured it out. It was simple enough.
I just disabled the COM port in the Device Manager window and enabled it again.
