不想嚼别人吃剩的馍.我只说我自己是怎么痛苦的连上的. 环境设备: window7笔记本,没有串口,装有XP和Ubuntu2个虚拟机(不是必须的,我只是说明一下我的环境) 友善之臂mini2440(含USB转串口设备一个,串口线一条) 尝试过程(官方手册完全是废): 手册是的环境是xp,自带“超级终端”.于是我自己百度下载超级终端,搞了不成.我想可能是win7不好用. 改为虚拟机里用Ubuntu,安装minicom,总是出现"cannot open dev ttyusb0".dmesg的

FTDI公司的FT2232系列芯片可实现USB与异步串行口RS232/RS485.同步串行总线IIC/SPI/JTAG相互通信,市场占有率,使用普遍. FTDI芯片有两种类型的驱动:virtual COM port driver (VCP)和D2xx.VCP就是常用的U转串COM驱动,实现USB到虚拟串口功能,应用于异步RS232/RS485与USB间通信,linux设备文件为/dev/ttyUSBx:D2XX应用于同步串行总线IIC/SPI/JTAG与USB间通信,整个驱动框架都有FTDI公司
看了一篇文章<debug by printing>,文中提到了多种通过printk来调试驱动的方法,其中最有用的就是"Dynamic debugging". “Dynamic debugging"的官方文档:http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/dynamic-debug-howto.txt?id=HEAD "Dyanmic de
This is a tutorial on how to program the Serial Ports on your Linux box.Serial Ports are nice little interfaces on the PC which helps you to interface your embedded system projects using a minimum number of wires.In this tutorial we will write a smal
In this tutorial we will learn How to communicate with an external device like a microcontroller board or modem using the Serial port of a windows PC(Windows XP,7). The software is written using C language and communicates with the Serial Port using
