C# write to USB-6001

I already have a task created in MAX.

I am loading the task using Task Setpoint_Task = NationalInstruments.DAQmx.DaqSystem.Local.LoadTask("Setpoint");

The channel is called AO-0 in MAX.

I am not sure what I need to do to set that channel to 5V.

nyc,

When you create a voltage analog output task in NI MAX, you will set the signal output range to a maximum of 5 volts, and then at the top you will set the voltageOut to 5 volts.

From reading the Help file, it appears that I would need to

Task setpoint_Task = NationalInstruments.DAQmx.DaqSystem.Local.LoadTask("Setpoint");
AOChannel aochannel_setpoint = setpoint_Task.AOChannels[0];
AnalogSingleChannelWriter setpoint = new AnalogSingleChannelWriter(setpoint_Task.Stream);
            setpoint.WriteSingleSample(true, 5);

nyc,

I thought that you were asking about how to set up the 5 volts output using NI MAX. The code that you posted seems to be right to me. The following white paper can help you with the DAQmx functions. 

Mapping the NI-DAQmx .NET API to the NI-DAQmx C API - NI-DAQmx .NET Class Library Help for Visual Studio 2010

Please give this a try and let me know.
