准备：
1].硬件：RTL-SDR R820T2 TUNER，30元左右一个
2].CentOS
1.下载RTL-SDR软件
git clone git://git.osmocom.org/rtl-sdr.git
2.编译&安装
$cd cmake
$cmake ..
$make install
增加/etc/modprobe.d/no-rtl.conf
blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830
3.接收FM广播
$rtl_fm -f 955e5 -M wbfm -s 480k -r 48000 - | aplay -r 48k -f S16_LE
4.复位USB接口
#include <stdio.h>
#include <fcntl.h>
#include <errno.h>
#include <sys/ioctl.h>
#include <linux/usbdevice_fs.h>
void main(int argc, char **argv)
{
const char *filename;
int fd;
filename = argv[1];
fd = open(filename, O_WRONLY);
ioctl(fd, USBDEVFS_RESET, 0);
close(fd);
return;
}
