USB-6289 Setting Digital output signals

[DPearce]

I am using a USB-6289. I am writing a CVI application which uses this device. I need to set the Digital I/O pins as outputs. In the CVI application I know that I can create these tasks with Tools->Create/Edit DAQmx Tasks. It created this:

int32 CreateDAQTaskInProject(TaskHandle *taskOut1)
{
 int32 DAQmxError = DAQmxSuccess;
    TaskHandle taskOut;

 DAQmxErrChk(DAQmxCreateTask("DAQTaskInProject", &taskOut));

 DAQmxErrChk(DAQmxCreateDOChan(taskOut, "USB-6289/port0",
  "DigitalOut", DAQmx_Val_ChanForAllLines));
 DAQmxErrChk(DAQmxSetChanAttribute(taskOut, "DigitalOut", DAQmx_DO_InvertLines, 0));

    *taskOut1 = taskOut;

Error:
 return DAQmxError;
}

So this sets it up but doesn't write the data out. My question is what is the command to write the data out?

Also I was wondering if there any example source code which shows how these commands are done? Is there a way to configure the bits individually? I only need to use 5 of these pins as outputs so t would be coll if I could write to only bits D0-D4.

Are there any documents written on these commands and how they are used?

thanks in advance

A DAQmxWrite writes the data.

Go to Help>Find Examples>Hardware Input and Output>DAQmx>Digital Generation.

If you specify lines instead of a port, you can use however many bits as you want.

First look at the CVI help.
