Embedded DAQPad

[gregory.poirier]

Hello,

I am trying to find a solution for my application. I need to sample and digitalise 65 analog signals on my application (electronic board) and then to send it with USB 2.0 or Firewire to Labview on my PC.

First, I need to know how to write a driver for Firewire or USB 2.0 or if I can use an existing driver (Licensed ?) which works with a DAQPad and modify it?

Secondly, I need to know how to communicate between my electronic board and Labview ?

Are they any application notes or white paper or datasheet or anything else which could help me to do it ?

I need to build my own DAQPad on my electronic board.
Note : I can't use a DAQPad solution for some reasons.

Thanks for any help.

If you're stuck with building your own DAQPad instead of using the NI Firewire DAQPad, creating drivers and communication layer is going to be dependent on what hardware you choose. Any papers on this would have to come from the manufacturer.

You might be able to get away with something prebuilt if you look at PC104 devices. These are small devices controlled by a small single board computer. You may be able to "embed" this on your device. Creating drivers and a comm layer would probably end up costing more that purchasing something that already has it. Many of these can talk to LabVIEW via a .dll.

LabVIEW has many communication protocals built-in, so that shouldn't be a problem.
