在linux下，用minicom作为终端连接ARM开发板。由于电脑没有串口，需要用usb转串口
首先接上usb转串口，在终端输入：
lsusb查看信息：
crazyleen@crazyleen-desktop:/dev$ lsusb Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
其中这个Bus 003 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port就是我的usb转串口器
然后查看器驱动： ls /dev/ttyUSB*
crazyleen@crazyleen-desktop:/dev$ ls /dev/ttyUSB* /dev/ttyUSB0
我的串口设备文件就是/dev/ttyUSB0
接下来设置minicom
提示：安装minicom：sudo apt-get install minicom
输入：sudo minicom
