I need to output sinusoidal signal using NI channel
I code like following;
s=daq.createSession('ni'); ch=s.addAnalogOutputChannel('6711',0,'Voltages'); rate=66000; s.Rate=rate; f=3300; t=(1:rate)/rate; output=sin(2*pi*f*t);
s.queueOutputData(output);
lh=addlistener(s,'DataRequired',@queueMoreData);
startBackground(s);
pause(); delete(lh)
// and function queueMoreData is like following
function queueMoreData(src,event) rate=66000; f=3300; t=(1:rate)/rate; output=sin(2*pi*f*t); s.queueOutputData(output); end
and as a result of these code, only one period runs.. I want the sin signal running continuously until I command not to..
What's the problem??
