基于am3358的蜂鸣器测试

#include <sys/ioctl.h>#include<stdio.h>#include <fcntl.h>#include <sys/types.h>static int fb;int main(){ int i=0; printf("hello world !\n"); fb = open("/dev/beep", O_RDWR); if (fb < 0) {perror("open device beep fail"); }for(i=0;i<100;i++) {ioctl(fb, 1, i);usleep(200000); }ioctl(fb, 0, 1);//关闭蜂鸣器驱动close(); return 0;}

，微风吹过，海面上金光闪闪，泛起一道道美丽的浪花，
