1.讀取鍵盤的值，進行相應的處理。

#include <stdio.h>

        fd_kb = open("/dev/input/event1", O_RDONLY); //鍵盤輸入
        if(fd_kb <= 0)
        {
                printf("open device error\n");
                return 0;
        }

        while(1)
        {
                if(read(fd_kb, &event_kb, sizeof(event_kb)) == sizeof(event_kb))
                {
                    if (event_kb.type == EV_KEY)
					{
                        //if (event_kb.value == 0 || event_kb.value == 1)//1表示按下，0表示釋放，會檢測到兩次
						if (event_kb.value == 1)//鍵按下
                        {
                                //printf("key %d %s\n", event_kb.code, (event_kb.value) ? "Pressed" : "Released");

					}
				
                }
				
				
				
        }
        close(fd_kb);
        return 0;
}
 

#include <stdio.h>
#include <linux/input.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int main()

					} 	


	
					if(event_mouse.code == BTN_LEFT && event_mouse.value==1)//左鍵按下，1表示按下，0表示釋放。不然會檢測到兩次
						printf("left down: %d\n", event_mouse.code);
