Signal source window with custom actions
This example implements a realtime random signal generator including custom functions to start or stop generating signal
#this variable defines a display rate of the signal generator
displayRate = 0
#add Start/Stop custom commands to the context menu
function getCustomActions( )
return ["Start", "Stop"];
end
#react to Start/Stop custom commands by setting display rate accordingly
function customAction( action :: String )
if( action == "Start")
global displayRate = 100
elseif ( action == "Stop")
global displayRate = 0
end
end
#generate signal
function update( output_signal:: SigviewSignalWindow )
if( displayRate == 0 )
return false
end
output_signal.samples = rand(-1000:1000, 1000 )
output_signal.samplingRate = 1
return true
end
#provide update interval by using internal display rate variable
function getUpdateIntervalMSec( )
return displayRate;
end
