You can use a vector_source_x block to pull samples into a flowgraph from a vector though. Tom (Ok, so it's possible to call work/general_work yourself from outside of a flowgraph, but it's very difficult to set up and do and almost certainly not worth the hassle.) > 2016-04-18 21:18 GMT+08:00 Tom Rondeau <[email protected]>: > >> On Mon, Apr 18, 2016 at 3:53 AM, Ekko <[email protected]> wrote: >> >>> hello all >>> i want to know how to write a c program with the lib of gnuradio. >>> for example i want to write a c program,to add a 15HZ sin signal with a >>> 135HZ sin signal,then send from the usrp. >>> i know how to send the data to the usrp.but i don't know how to use the >>> signal source and the add fnuction of gnuradio in c program,just like use >>> the uhd api as a fnuction. >>> i will not want to write a oot block,i just want to write a *.c file to >>> accomplish this work. >>> but i don't how to start. >>> is there some demo in gnuradio about how to use the gnuradio with C?just >>> like the tx_samples_c.c in uhd. >>> or something others to teel me how to solve this . >>> >>> >>> >>> thank you >>> >>> --Ekko >>> >> >> >> Ekko, >> >> No, you cannot write a C program.
