Applied latest patch set from Mint and from then on the serial port cannot be found. I've followed previous posts, using each USB port in turn, checked 'groups' membership, and 2 Arduino UNO's, looked at the Windows 8 posts on driver permissions (not directly relevant for Linux), but ...
It actually found the com ports. The cause of the error: I realized when I debugged. Some functions defined after the" ifname== 'main': app.run(debug=True, host="0.0.0.0") "line. Normally when running from the console there was no problem but it was from exe. it worked when ...
将头文件改为以下两行代码即可,其原因是所用头文件被包含在另一个文件中,无法直接检索 1 2 #include <QtSerialPort/QSerialPort> #include <QtSerialPort/QSerialPortInfo> 【关注我】。

Code works fine when tested on Arduino Uno, (editing delay(x) affects the led), but I get this error and Serial Port Monitor does not show anything. Error in CLion Event Log is: Error running Unnamed: Cannot run program "C:\Users\Nikhil Verma\.CLion12\system\cmake\generated\4b320303\...

只要把事件驱动串行控制这个选项勾选起来，必须关闭再重新打开mach3，就可以打开串口监控窗口。这个选项在菜单–设置–端口/针脚–端口设置和轴向选择–右下角倒数第二个。
针对你遇到的 serial.serialutil.SerialException: could not open port 'com1': FileNotFoundError 错误,我们可以从以下几个方面进行排查和解决: 确认错误信息的完整性: 错误信息已经明确指出无法打开端口 'com1',原因是 FileNotFoundError。这通常意味着系统找不到指定的文件或路径,在这里指的是找不到指定的串口。
