Arduino Pro Micro 未上传任何代码(avrdude : ser_open(): can't open device "/dev/ttyACM0": Permission denied)

Question

我尝试上传任何类型的草图(包括最基本的草图)，但没有任何效果。其他人说这个错误是由于端口权限不足引起的，所以我按照其他几个人和 arduino 站点(对于 linux)的建议做了。

Sketch uses 3462 bytes (12%) of program storage space. Maximum is 28672 bytes.
Global variables use 149 bytes (5%) of dynamic memory, leaving 2411 bytes for local variables. Maximum is 2560 bytes.

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

来自documentation :

Open Terminal and type:

ls -l /dev/ttyACM* you will get something like:

crw-rw---- 1 root dialout 188, 0 5 apr 23.01 ttyACM0 The "0" at theend of ACM might be a different number, or multiple entries might bereturned. The data we need is "dialout" (is the group owner of thefile).

Now we just need to add our user to the group:

sudo usermod -a -G dialout $USER then:

sudo chmod a+rw /dev/ttyACM0 You will need to log out and log in againfor this change to take effect.

然而，每次我启动 arduino 时，权限都会被清除回原来的状态。如果我以 sudo 的方式运行 arduino，它会起作用，但我显然不需要这样做。

我没有足够的经验知道使用什么程序员来开发 arduino，但问题是我使用的是“AVR ISP”，但是当我切换到“ArduinoISP”时，一切都完美上传。无需更改任何权限。
