Chapter 4 Programming Guide

4.1 Overview

The PCI-1718 cards are delivered with an easy-to-use 32-bit Device Driver for user programming under the Windows 98/2000/XP operating systems.

At the Windows driver level, PCI-1718 cards are fully compatible with the PCL-818 series so you can easily use older applications of the PCL- 818 series with PCI-1718 cards.We also advise users to program the PCI- 1718 cards using the 32-bit Device Drivers provided by Advantech to avoid the complexity of low- level registry programming.

4.2 Programming with the Driver

Your program can perform A/D by writing all the I/O port instructions directly, or you can take advantage of the PCI-1718 driver. We suggest that you make use of the driver functions in your program. This will make you programming job easier and improve your program’s performance.

See the Software Driver User’s Manual for more information.

4.3 Register Programming.

The most important consideration in programming the PCI-1718 cards at register level is to understand the function of the card's registers and the process of programming. The information in the following sections is provided only for users who would like to do their own low- level pro- gramming.

Without the driver you would do the following: perform software trigger, pacer trigger with interrupt, pacer trigger with interrupt and FIFO, and program a controlled data transfer.
