What is the WFMsingleBufAsync Example supposed to output?

[roz]

Hardware: 6711 Software: VB. I don't measure any output with the WFMsingleBufAsync example. Does the buffer that is supposed to be output ever get filled, or is it just outputing 0 Volts? How and at what point in the Waveform generation procedure does the buffer get filled?

Greetings,

The NIDAQMakeBuffer() function fills the buffer. Since the ulType input paramter is set to WFM_DATA_F64, the buffer contains a 10 period sinewave (0 - 4.99). Are you using the correct device number? How are you measuring the output? Have you verified that your board is outputting correctly with its Test Panel in Measurement & Automation Explorer (MAX)?

The Test Panel outputs correctly and some of the example functions output correctly (such as WFMsingleBufSync). The AOonePoint example doesn't output anything either. I am measuring the output from the TBX-68 terminal block using an oscilloscope and I have also tried using a multimeter for the single point functions and I just measure a voltage spike and then 0V.
Is it only possible to fill the buffer with the WFM_DATA_U8, WFM_DATA_I16, WFM_DATA_F64, WFM_DATA_U32 ulTypes? What do I do if, for instance, I want to have a 2V sine wave, or a different period?
