连线方式
Cable Pin on Cubieboard
GROUND (BLACK) GND #接地
MUST NOT BE CONNECTED VCC #这个是不能接的
PIN2 (GREEN) RX #TTL读
PIN1 (WHITE) TX #TTL写
Exclamation-red.png WARNING: DO NOT CONNECT THE RED LINE TO VCC.
一、可以上 http://linux-sunxi.org/Cubieboard/TTL
这里面介绍的是 gtkterm 链接方式
现在一个简单的介绍
stty -F /dev/ttyUSB0 -crtscts # turn off hardware flow control - the cable has no wires for that
cu -s 115200 -l /dev/ttyUSB0
screen /dev/ttyUSB0 115200
gtkterm -p /dev/ttyUSB0 -s 115200
如不能链接则是用下面命令查看
$ sudo cu -s 115200 -l /dev/ttyUSB0
cu: open (/dev/ttyUSB0): Permission denied
cu: /dev/ttyUSB0: Line in use
一般的解决方法是
$ sudo usermod --append --groups dialout myusername
二、minicom的安装
sudo apt-get install minicom
1、查看USB转串口设备是否存在
ls -l /dev | grep ttyUSB
如果成功连接USB转串口工具，那么可以查找到ttyUSB0或ttyUSB1等。 //这个是USB转TTL的
也可以用lsusb 查看usb端口
我的如下
zhz@zhz:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 009: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 005 Device 010: ID 18d1:0003 Google Inc.
Bus 005 Device 007: ID 0e8f:0016 GreenAsia Inc. 4 port USB 1.1 hub UH-174
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 002: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
zhz@zhz:~$
这个就是我的TTL链接
Bus 005 Device 009: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
2、配置
sudo minicom -s
进入初始化设置
+-----[configuration]------+
| Filenames and paths |
| File transfer protocols |
| Serial port setup |
| Modem and dialing |
| Screen and keyboard |
| Save setup as dfl |
| Save setup as.. |
| Exit |
| Exit from Minicom |
+-------------------------
选择 serial prot setup
按如下设置
+-----------------------------------------------------------------------+
| A - Serial Device : /dev/ttyUSB0 |
| B - Lockfile Location : /var/lock |
| C - Callin Program : |
| D - Callout Program : |
| E - Bps/Par/Bits : 115200 8N1 |
| F - Hardware Flow Control : No |#需要关，否则没按键控制不了
| G - Software Flow Control : No |
| |
| Change which setting? |
+-----------------------------------------------------------------------+
| Screen and keyboard |
| Save setup as dfl |
| Save setup as.. |
| Exit |
| Exit from Minicom |
+--------------------------+
3、首先在命令行下执行sudo minicom启动程序的 进入 cubieboard
可以开始调试 cubieboard ，#可以用sudo minciom -c on 命令进入带颜色的调试
（1）首先在命令行下执行sudo minicom启动程序的
（2）进入主界面后按 Ctrl+A 然后再按Ｚ
可以进入配置界面
当 sudo minciom 进入不了。报如下错误
Device /dev/ttyUSB0 is locked.
可以用
sudo rm /var/lock/LCK..ttyUSB0 删除
再用sudo minicom 重新开始
