- 实现一个简单的shell,实现步骤:(1)在虚拟的shell界面上出现命令提示符($或#); (2)获取用户指令:获取用户在命令提示符后面输入的命令及其参数,并注意命令输入的最大长度; (3)解析指令:对用户输入的命令进行解析,解析出命令名和参数; (4)寻找命令文件:每个命令的执行都必须依靠对应的可执行文件,这些文件的存放路径存放在用户的PATH环境变量里; (5)执行命令:可通过fork( )系统调用创建一个进程来完成执行命令的任务,具体的命令执行用execv( )函
USB-serial-driver
- 这个结构是定义一个USB串行驱动。它提供了所有的的信息USB系列核心代码的需要。如果函数指针定义,然后当TTY端口功能一致的时候USB系列核心代码会叫他们是所谓的天圆。如果他们不被调用,则为通用串行函数来代替。-This structure is defines a USB Serial driver. It provides all of the information that the USB serial core code needs. If the function pointer
CPUfreq
- 该程序模块中xllp_CPUfreq.s,xllp_freq.c,xllp_intc.s,xllp_freq.h四个文件是修改CPU频率的主要代码,使用前可以将这些文件和xllp目录下的文件编译在一起,以便可以在程序的任何地方调用它们,修改和读取CPU频率主要依靠调用xllp_freq.c文件中的两个函数完成:XLLPSetCoreRunFrequency,xllpGetCurrentFreqSetting。-The program module xllp_CPUfreq.s, xllp_fre
