【问题描述】:
我尝试上传任何类型的草图(包括裸骨草图),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 网站(适用于 linux)的建议做了。
Sketch uses 3462 bytes (12%) of program storage space. Maximum is 28672 bytes.

avrdude done. Thank you.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
打开终端并输入:
ls -l /dev/ttyACM* 你会得到类似的东西:
crw-rw---- 1 root dialout 188, 0 5 apr 23.01 ttyACM0 The "0" at the ACM 的结尾可能是不同的数字,或者可能是多个条目 回来。我们需要的数据是“拨出”(是 文件)。
现在我们只需要将我们的用户添加到组中:
sudo usermod -a -G dialout $USER 然后:
sudo chmod a+rw /dev/ttyACM0 你需要退出并重新登录 使此更改生效。
但是每次我启动 arduino 时,权限都会被清除回原来的状态。如果我将 arduino 作为 sudo 运行,它可以工作,但我显然不需要这样做。
