need advice: IMAQ 1408

[lam chun-wei]

I'm working on my senior design in which i need to acquire 25 pixels
(8-bit each) from a IMAQ PCI-1408 video source and pass the data to a DSP
chip. What is the easiest way for doing it? Is Labview the best
option? (other options include VB, C, ...)

Thanks,
Chun-wei

LabVIEW is easily the fastest way to do this (in terms of development time) and probably quite comparable to the speed of other languages for this application, particularly since the overall speed will be fairly well balanced between I/O and processing. If your DSP is in a standalone board, you may even want to use a digital I/O board to output the data directly to the DSP from the host. Use a handshaking mode from the DIO. The IMAQ software will allow you to extract the pixels you need and pipe them easily to the DSP.

Hi Chun-wei,

The IMAQ driver for the PCI-1408 provides you a programming interface for LabVIEW, VB, C and VC++. LabVIEW maybe the best option as it provides a graphical programming environment and much of the work is already done for you in the driver level VIs. I would suggest that you go to the developer zone resource library to check out some example code for both C and LabVIEW, and see which one you prefer.
