how to do a voltage ramp

[jpnavarini]

Hello All,

              I'm a beginner on LabView and have written a program to generate the following ramp shown below. From the graph it appears to be working, however when I plug in a scope or voltmeter into the board, I see no output. Why?

riclambo,

I'm guessing that the DAQmx Clear Task.vi is stopping the task before the waveform can be generated.  Take a look at example that ships with LV titled Cont Gen Voltage Wfm-Ext Clk-Dig Start.vi  Pay particular attention to how the DAQmx Is Task Done.vi is used to determine when the task is cleared.
