three questions

[tyro]

1 .I want to control a stepper motor by using the PCI 6024E
card. Can I realize it? How to do ?
2 .What is the difference between Call Library Function and Code
Interface Node, why does Call Library Function need .dll, but Code
Interface Node need .lsb, They are both dynamic link library, why does
NI not use one form?
3 .There are three .vis in labview ,( waveform generation->sine
waveform.vi ,signal processing->signal generation ->sine pattern.vi
and sine wave.vi)I want know the difference,
anyone can tell me ,I'll
be very appreciated!

Hi,

About your second question:

Using dll in LV good when you want use existing libraries.
CIN good when you write your code because you work with data structures in same format that they are stored in LabVIEW.

About your third question:

Sine Wave and Sine Pattern makes same thing but you use them with different parameters. There are cases when it more easy to use Sine Wave.
Sine Waveform is good because it returns Waveform (not Array) that consists more data about wave and you can use more functions for wave operatings.

For first question - post it separately.
