MicroPython PyCharm 2021.3.3插件权限错误

Question

我试图在PyCharm 2021.3.3上设置MicroPython，但不幸的是，我无法成功将我的板连接到IDE。我正在尝试使用工具>gt；MicroPython>gt；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

然后我尝试刷新简单的程序来控制，尽管之前有错误，但它吐出来了：

Connecting to COM4
Traceback (most recent call last):
File "C:UsersreczulAppDataRoamingJetBrainsPyCharm2021.3pluginsintellij-micropythonscriptsmicroupload.py", line 139, in <module>
main(sys.argv[1:])
File "C:UsersreczulAppDataRoamingJetBrainsPyCharm2021.3pluginsintellij-micropythonscriptsmicroupload.py", line 56, in main
board = Pyboard(port)
File "C:UsersreczulPycharmProjectspythonProject1venvlibsite-packagesampypyboard.py", line 147, in __init__
raise PyboardError('failed to access ' + device)
ampy.pyboard.PyboardError: failed to access COM4

我能做些什么来修复这个错误？

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

您很可能会出现此错误，因为您在插入设备时按下了"BOOTSEL"按钮。

将你的UF2文件拖到设备上，它应该会重新启动。这次不要拔下设备插头并按住"BOOTSEL"。

现在去应该很好。
