using multiple channels DAQ

[nampostech]

HI!

I am new user Labview and NI DAQ. Now I am programming for a simple task, but I don't know where I should start from.

I am using Labview 8.6, hardware: NI PCI 6281 and BNC 2120.

Requirement:
1. Generate PWM signal to control the speed of motor

2. Generate 3 Digital output signal to control the direction of rotation (CW, CCW, brake)

Therefore I should generate simutaneously 1 Analog and 3 Digital signal to my driving circuit.

Please help me, or give some advices.

Thank and regard

as a start labview ships with some good examples. 
and there is a tutorial on the NI site

HI Buddy,

Just start learning the tutorials before see the link below and get more about your devices and there in the manual u coulds find  all you need

Thanks for your advice.

Actually, I already started with a simple PWM program. It is used to generate PWM signal through AO and its function is to adjust duty cycle only.

Now I should upgrade to the next version that: generate DO and AO at the same time.
That makes me stuck ~~!

Put all DAQ assistance into one While loop??

on avarage PWM is generated with a digital IO. ( that is the bennefit from PWM to other control meganisems )
