<P><SPAN
style="FONT-FAMILY: Tahoma">键盘是用户对电脑进行输入的最常用工具，所以创建某类的驱动来处理和管理键盘很重要。当你开始考虑这个的时候，应该先获取一些键盘的要素，比如：当按下一个键的时候怎么样得到它，如何把所谓的“扫描码”转换成我们可以正确理解的标准</SPAN><FONT
face=Tahoma><SPAN lang=EN-US>ASCII </SPAN></FONT><SPAN
style="FONT-FAMILY: Tahoma">字符。</SPAN></P>
<P><SPAN
style="FONT-FAMILY: Tahoma">扫描码仅仅是一个键号。键盘给键盘上的每个键分配一个号码，这就是扫描码。扫描码一般从左上到右下依次编号，同时有少量异常以与老式键盘向下兼容。你必须使用一个检查表（一个数组）并且把扫描码作为表的索引。检查表被称为
键映射（</SPAN><FONT face=Tahoma><SPAN lang=EN-US>keymap</SPAN></FONT><SPAN
style="FONT-FAMILY: Tahoma">），并用来快速地把扫描码转换为</SPAN><FONT face=Tahoma><SPAN
lang=EN-US>ASCII</SPAN></FONT><SPAN
style="FONT-FAMILY: Tahoma">码值。最后一点需要注意的是，如果第</SPAN><FONT face=Tahoma><SPAN
lang=EN-US>7</SPAN></FONT><SPAN style="FONT-FAMILY: Tahoma">位被设置（用“</SPAN><FONT
face=Tahoma><SPAN lang=EN-US>scancode & 0x80</SPAN></FONT><SPAN
style="FONT-FAMILY: Tahoma">”语句测试），就说明一个键刚被释放。创建你的“</SPAN><FONT
face=Tahoma><SPAN lang=EN-US>kb.h</SPAN></FONT><SPAN
style="FONT-FAMILY: Tahoma">”并完成所有标准程序，比如为</SPAN><FONT face=Tahoma><SPAN
lang=EN-US>GCC</SPAN></FONT><SPAN
style="FONT-FAMILY: Tahoma">添加一行、添加一个文件到</SPAN><FONT face=Tahoma><SPAN
lang=EN-US>LD</SPAN></FONT><SPAN style="FONT-FAMILY: Tahoma">的命令行。</SPAN></P>
