本人编写一个测试程序能捕捉红外设备/dev/inout/event1的的按键信息:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

void main(int argc,char *agrv[])
{


char devstr[256];
FILE *fp;
char key;
strcpy(devstr,"/dev/input/event1");

printf("Get the status of the system IR buttons:\n");
int count=0;
while(1)
{

      fp=fopen(devstr,"r");
      if(fp)
      {
         while(1)
         {
            if(fscanf(fp,"%c",&key)!=-1)
               {
                  count++;
                  if(count<=15)
                  {
                     printf("%02x,",key);
                  }
                  else
                  {
                     printf("%02x\n",key);
                     count=0;
                     }
               }
            else
            {

               break;
            }
         } //while in
      fclose(fp);
      }//if
      usleep(50000);
}//while out
}

请问大虾在ANDROID下怎样映射红外接收的按键与系统按键的对应关系，在此先谢谢了！

Android 本身有一个genevnet 和 sendevent 工具用来从内核获取event事件和向内核发送event事件，具体可以参考 Android 下收发input事件的工具 getevent 和 sendevent
o get_evnet 是一个可以获得注册成input设备上报event的调试工具。
o usage: get_event /dev/input/eventX, X is 0, 1, 2，3, 4, 5，6
o 附件为其源代码，可以采用静态编译，然后通过adb push进手机，进行调试。
arm-linux-gcc -static get_event.c -o get_evnet

请问一下
我在Android 系统下
把自行编译好的sun7i-ir.ko覆盖原本的档案
进行重新开机
为何开机就不能自动执行sun7i-ir.ko?
