#ifndef KEYBOARDFUNC_H
#define KEYBOARDFUNC_H
void KeyboardFunc(void);

#endif

具体使用：

1、把keyboardfun.h拷到include/geekos
2、把keyboardfun.c拷到src/geekos
3、Makefile中KERNEL_C_SRCS后添加keyboardfun.c
4、在main.c中添加：#include <geekos/keyboardfun.h>
      和Start_Kernel_Thread((Thread_Start_Func)KeyboardFunc,0,PRIORITY_HIGH,true);


添加完成后需要修改keyboard.c
1、s_scanTableNoShift[] s_scanTableWithShift[]中的'\r'改成'\n'
2、注释186行
3、Enqueue_Keycode(keycode);
    改成
    if(!release)
    {
Enqueue_Keycode(keycode);
    }
