MicroPython PyCharm 2021.3.3插件权限错误

Question

我试图在MicroPython 2021.3.3上设置PyCharm，不幸的是，我无法成功地将我的板连接到PyCharm上。我正在尝试使用tools>>MicroPython>>MicroPython REPL：

Found the device, but could not connect via port 'COM4': could not open port 'COM4': PermissionError(13, 'Odmowa dostępu.', None, 5)
I'm not sure what to suggest. :-(
Press ENTER to continue

然后，我试图冲洗简单的程序来控制，尽管之前的错误，它喷出：

Connecting to COM4
Traceback (most recent call last):
  File "C:\Users\reczul\AppData\Roaming\JetBrains\PyCharm2021.3\plugins\intellij-micropython\scripts\microupload.py", line 139, in <module>
    main(sys.argv[1:])
  File "C:\Users\reczul\AppData\Roaming\JetBrains\PyCharm2021.3\plugins\intellij-micropython\scripts\microupload.py", line 56, in main
    board = Pyboard(port)
  File "C:\Users\reczul\PycharmProjects\pythonProject1\venv\lib\site-packages\ampy\pyboard.py", line 147, in __init__
    raise PyboardError('failed to access ' + device)
ampy.pyboard.PyboardError: failed to access COM4

我能做些什么来纠正这个错误？

我使用的示例代码：

from machine import Pin, Timer

led = Pin(25, Pin.OUT)
tim = Timer()
def tick(timer):
    global led
    led.toggle()

tim.init(freq=2.5, mode=Timer.PERIODIC, callback=tick)```

假设您使用的是Pi Pico..

您很可能会收到此错误，因为您按下'BOOTSEL‘按钮时，您的设备插入。

将您的UF2文件拖到设备上，它将重新启动。不要拔掉设备，这次拿着'BOOTSEL‘。

现在该走了。
