测试写好的输入设备模块,比如遥控器,交叉编译后bin档放到rootfs/bin,直接运行
/* test remote.ko * you should insmod remote.ko and config it before */ #include <stdio.h> #include <stdlib.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <unistd.h> #include <linux/input.h>
struct input_event buff;
int main(int argc, char **argv) { int fd;
printf("%s: entered/n", argv[0]);
fd = open("/dev/input/event0", O_RDONLY); if(fd == -1) { printf("open failed"); exit(-1); } printf("%s: open successful: %d/n", argv[0], fd); while(1) { if(read(fd,&buff,sizeof(struct input_event))!=0) printf("type:%d code:%d value:%d/n",buff.type,buff.code,buff.value); } close(fd);
