Protected Member Functions | |
| virtual frame_settings | node_init (void) |
| Override this function with your implementation. This function has the same function as node_process except that it is called only once and before anything has been transmitted and received. The function is called before synchronizing against the PPS. Here you can place any time consuming initializations you may need. | |
| virtual frame_settings | node_process (void) |
| Override this function with your implementation. This is the most important function of your implementation. The function returns a "frame_settings" value which defines when then next frame should be transmitted, if it is a transmit or receive buffer. If it is a transmit frame then you should fill the transmitter buffers, d_tx_buffers, with the signal that should be transmitted before exiting node_process. If the previous frame was a receive frame then you should process the samples in d_rx_buffers. The frame_settings of the previous frame is stored in d_old_frame_settings. | |
| virtual void | end_of_run (void) |
| Override this function with any post processing you may want to do. | |
