Hello Everyone, I am a relatively new user to the USRP2 and currently would like to make some changes to how an external PPS signal is deciphered. As of now, I believe that once the first rising edge of a PPS signal is detected, the USRP2 will continually collect data until it is programmed to stop. What I am hoping to do is collect data when the PPS sends a rising edge and pause the data collection when a falling edge is detected. Basically the external PPS signal is going to act as a TR switch. So far I have been looking through the rx_timed_samples.cpp and the header file clock_config.hpp programs to plan out my approach. The problem where I am getting stuck is telling the USRP to pause data collection on a falling edge. I have not found any function in the libraries that is able to do this. Has anybody been able to program the PPS input to act as a TR switch or have any ideas about how to about this? Any information on this would be greatly appreciated.
Thank you very much, Rob -- View this message in context: http://old.nabble.com/Using-PPS-as-a-sampling-trigger-tp33312321p33312321.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
