+################################################## + +XMLRPC allows software to make remote function calls over http. +In the case of GRC, one can use XMLRPC to modify variables in a running flow graph. +See http://www.xmlrpc.com/ + +--- Server Example --- +Place an "XMLRPC Server" block inside of any flow graph. +The server will provide set functions for every variable in the flow graph. +If a variable is called "freq", the server will provide a function set_freq(new_freq). +Run the server example and experiment with the example client script. + +-- Client Example -- +The "XMLRPC Client" block will give a variable control over one remove function. +In the example client, there is one client block and gui control per variable. +This technique can be used to remotely control a flow graph, perhaps running on a non-gui machine. diff --git a/gnuradio-examples/grc/xmlrpc/xmlrpc_client.grc b/gnuradio-examples/grc/xmlrpc/xmlrpc_client.grc new file mode 100644 index

Allows the max rate deviation to be independent of the integer rate. Scaling of the differential taps also allows alpha and beta to operate independent of the rate when fractional samples per symbol are used. Slightly more tolerant to large signal values, but they still should be close to +/-1. --- gnuradio-examples/grc/demod/pam_timing.grc | 760 ++++++++++++++++------------- 1 file changed, 410 insertions(+), 350 deletions(-) (limited to 'gnuradio-examples/grc') diff --git a/gnuradio-examples/grc/demod/pam_timing.grc b/gnuradio-examples/grc/demod/pam_timing.grc index 907233aca..4e2a2f861 100644 --- a/gnuradio-examples/grc/demod/pam_timing.grc +++ b/gnuradio-examples/grc/demod/pam_timing.grc @@ -1,6 +1,6 @@ -
