用tc在dos下显示高分辨率的方法 键盘是电脑最基本的输入设备，对101键盘上所有键直接管理，而且直接判断所有键的状态是按下还是释放。此键盘程序适用于游戏等即时性的键盘应用，如果用来管理打字等还应加上键盘缓冲区方面的管理。 /*保存为keyboard.c*/ /*由define定义的，SCAN_开头的是键盘扫描码，可用kbkflag[]数组判断某个键的状态 具体的键盘扫描码可参考其它书籍,KEY_开头的是键盘返加的ASCII码，可用getkey()函数得到。 ，为了减少篇幅，只定义游戏中用到的控制键及少数其它键。*/ #ifndef KEYBOARD #define SCAN_CAPSLOCK 58 #define SCAN_LEFTSHIFT 42 #define SCAN_RIGHTSHIFT 54 #define SCAN_SHIFT (keyflag[SCAN_RIGHTSHIFT]||keyflag[SCAN_LEFTSHIFT]) #define KEY_CTRLBREAK 248 #define KEY_INSERT 236 #define KEY_CAPSLOCK 230 #define KEY_F11 229 #define KEY_F12 228 #include #include static unsigned char asciinames[]= { 0,27,1,2,3,4,5,6,7,8,9,0,-,=,8,9, q,w,e,r,t,y,u,i,o,p,[,],13,0,a,s, d,f,g,h,j,k,l,;,39,`,0,92,z,x,c,v, b,n,m,,,.,/,0,*,0, ,0,0,0,0,0,0, 0,0,0,0,0,0,0,7,8,9,-,4,5,6,+,1, 2,3,0,127,0,0,\\, KEY_F11,KEY_F12,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 }; /*按下shift键返加数组*/ static unsigned char shiftnames[]= { 0,27,!,@,#,$,%,^,,*,(,),_,+,8,9, Q,W,E,R,T,Y,U,I,O,P,{,},13,1,A,S, D,F,G,H,J,K,L,:,34,~,0,|,Z,X,C,V, B,N,M,,,?,0,*,1, ,0,0,0,0,0,0, 0,0,0,0,0,0,0, 7,8,9,-,4,5,6,+,1, 2,3,0,127,0,0,|,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 }; /*特殊键返回数组*/ static char specialnames[]= { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,13,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,/,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,KEY_CTRLBREAK,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 }; unsigned char lastascii; unsigned char lastscan; unsigned char keyflag[128]; /*键状态数组*/ static unsigned char capslock; static unsigned char curkeycode,lastkeycode; static void interrupt (*oldkeyinterrupt)(void); /*清除所有键*/ void clearkeyboard() { int i; lastscan=0;lastascii=0; memset(keyflag,0,sizeof(keyflag)); } /*新的INT9H键盘硬中断*/ static void interrupt newkeyboardinterrupt(void) { static unsigned char specialflag; unsigned char k,c,t
