Hi,

Currently I have code below

s = daq.createSession('ni');
addAnalogOutputChannel(s,'cDAQ1Mod2',0,'Voltage');
s.IsContinuous = true;
s.Rate = 10000;
data = linspace(-1,1,5000)';
lh = addlistener(s,'DataRequired', ...
         @(src,event) src.queueOutputData(data));
queueOutputData(s,data)
startBackground(s);
stop(s)

After executing stop(s), daq will stop generate new data. I just wanna to know if there is any way I can continue queueOutputData without create a new session?

Thanks sooo much!

My goal is to generate a triangular ramp signal that user could pause and continue whenever they want
