C#Avalonia串口通讯Linux部署测试

一、效果展示

虚拟两串口

C#Avalonia串口通讯Linux部署测试

打包程序

C#Avalonia串口通讯Linux部署测试

配虚拟机串口

C#Avalonia串口通讯Linux部署测试

虚拟机开机

C#Avalonia串口通讯Linux部署测试

运行程序

C#Avalonia串口通讯Linux部署测试

发现找不到串口，需要设置权限

C#Avalonia串口通讯Linux部署测试

Linux串口访问权限设置：

–要查询Linux系统中的当前用户可以使用whoami命令。

whoami

–将当前用户加入dialout组。命令：

sudo usermod -aG dialout debian

sudo adduser debian dialout

–查询所有串口

ls /dev/tty*

–发送串口消息

echo hello > /dev/ttyS0

–检查串口读写权限

ls -l /dev/ttyS0

–接收串口消息

cat /dev/ttyS0

串口权限正常了
