Dear all,
I got the transceiver code for UHD from Isaac
here<http://www.gergltd.com/home/2011/02/simple-uhd-transceiver-class/>.
The code is written in C++, just like the examples for UHD. He implemented 3
threads: tx_thread, rx_thread and processing_thread. Now I want to extend
this transceiver, e.g. to add modulation / demodulation. But I don't know
how to use the existing gnuradio blocks with C++.
My guess is I need to use the gr-uhd wrapper and have a python top block.
But I'm not very familiar with threading in python. Can someone show me how
to do these operations in python?
// Start up the thread
m_pRxThread = new boost::thread(&CSimpleTransceiver::rxThread,this);
and
void CSimpleTransceiver::rxThread()
{
// fill pBuff with received data
{
// Lock queue
boost::mutex::scoped_lock l(*m_pMutexRxQueue);
// Put data block on queue
m_pRxQueue->push_back(pBuff);
} // Unlock queue
}
Or is there a way to invoke gnuradio signal processing blocks in C++?
Thank you very much,
Johnny
