[英]C# Raspberry pi Linux serial port permission denied even as root
I am writing a program trying to communicate with serial ports of the raspberry pi. 我正在编写一个程序,试图与树莓派的串行端口进行通信。 The program can find the device linked to the port.
该程序可以找到链接到该端口的设备。 But when I want to open that port, it threw me an exception saying that the serial port can't be opened, permission denied.
但是,当我想打开该端口时,它抛出了一个异常:无法打开串行端口,权限被拒绝。 I logged as root(pi) and I think I added myself to "dialout".
我以root(pi)身份登录,我想将自己添加到“拨号”中。 However nothing worked.
但是,没有任何效果。 What will be the problem of my situation?
我的情况会是什么问题? Hope there's any could help, thanks in advance.
希望有任何帮助,在此先感谢。
