LimeSDR Getting Started Quickly LimeSDR 上手指南

LimeSDR Getting Started Quickly LimeSDR 上手指南，LimeSDR部分特性：

USB 3.0 ;

4 x Tx 发射天线接口 6 x Rx 接收天线接口;

可用于Wi-Fi, GSM, UMTS, LTE, LoRa, Bluetooth, Zigbee, RFID等开发测试环境中。

RTL电视棒、HackRF、BladeRF、USRP、LimeSDR参数对比表：

HackRF One的价格，性能参数却能跟BladeRF甚至USRP媲美!

LimeSDR核心组件：

先上几张特写：

主板长10cm，算上USB接口11.5cm：

主板宽5.7cm:

相对于HackRF、BladeRF、USRP这三款主流SDR硬件(USRP mini除外)，体积已经很小巧了。LimeSDR其体积实测只有一个iPhone5s的体积大小!

当插上USB供电后，除了上图显示的两颗绿色LED灯，还有一颗一闪一闪的红色LED灯也在工作。

接下来将分一键快速安装和源码编译安装来使用LimeSDR硬件，推荐使用源码编译安装。

0x01 Mac OSX

1.1 搭建开发环境

Mac OSX当中强烈推荐通过Mac Port 搭建SDR环境，配合源码编译达到最佳效果。

1.通过AppStore安装：Xcode

2.下载安装：XQuartz/X11

3.下载安装：MacPorts

sudo port search sdr

sudo port install rtl-sdr hackrf bladeRF uhd gnuradio gqrx gr-osmosdr gr-fosphor

完成之后便可从GayHub上clone源码并进行编译安装。

1.2 源码编译LimeSuite

git clone https://github.com/myriadrf/LimeSuite.git

cd LimeSuite

mkdir builddir && cd builddir

cmake ../

make -j4

sudo make install

1.3 源码编译UHD驱动&&增加UHD对LimeSDR的支持

jocover基于UHD给LimeSDR开发了LimeSDR的驱动支持OpenUSRP，把LimeSDR来模拟成USRP B210来使用。

git clone https://github.com/EttusResearch/uhd.git

cd uhd/host/lib/usrp

git clone https://github.com/jocover/OpenUSRP.git

echo "INCLUDE_SUBDIRECTORY(OpenUSRP)">>CMakeLists.txt

cd ../../../

mkdir build && cd build

cmake ..

make -j4

sudo make install

1.4 添加环境变量

echo 'export UHD_MODULE_PATH=/usr/lib/uhd/modules' >> ~/.bashrc

如果用的是iTerm2+zsh则执行：

echo 'export UHD_MODULE_PATH=/usr/lib/uhd/modules' >> ~/.zshrc

1.5 检测LimeSDR模拟USRP是否成功:

LimeSDR模拟成USRP B210之后最终的效果跟USRP是一样的：

uhd_find_devices

uhd_usrp_probe

Mac OS; Clang version 8.1.0 (clang-802.0.38); Boost_105900; UHD_003.010.001.001-MacPorts-Release

Using OpenUSRP

[WARNING] Gateware version mismatch!

Expected gateware version 2, revision 8

But found version 2, revision 6

Follow the FW and FPGA upgrade instructions:
