REDHAWK UHD设备使用方法

Question

我已成功安装了REDHAWK版本1.8.3的UHD设备.我不清楚如何将波形中的组件连接到由设备管理器管理的设备.我也不清楚IDL接口和USRP设备上的数据端口之间的相互作用.

我无法找到一个简单的例子来发送和接收利用USRP设备的波形(例如,信号发生器组件向USRP发送正弦波).有没有人有这个或任何建议的经验？

在运行环境中将组件连接到设备的一种方法是通过REDHAWK python模块.它能够连接到正在运行的域,查询任何已启动的应用程序并将端口从组件连接到设备.以下是一个示例python脚本(注意,为了使连接成功,端口必须是相同的类型):

from ossie.utils import redhawk
from ossie.cf import CF

# Connect to the running domain
domain = redhawk.attach("REDHAWK_DEV")

# Gets a reference to the running application
for app in domain.apps:
    # Find desired application
    if app.name == 'desired_name':
        application = app

# Gets the component from the application
for comp in application.comps:
    # Find desired component
    if comp.name == 'desired_name':
        component = comp

# Gets the device to connect
for devMgr in domain.devMgrs:
    for dev in devMgr.devs:
        # Find desired device
        if dev.name = 'desired_name':
            device = dev

# Gets the references to the input and output ports
comp_port = component.getPort('port_name')._narrow(CF.Port)
dev_port = device.getPort('port_name')

# Makes the actual connection
comp_port.connectPort(dev_port, 'ConnectionID')

# Make sure device is started
device.start()

# Start application
application.start()

# To disconnect:
# Stop device and application
application.stop()
device.stop()
comp_port.disconnectPort('ConnectionID')
