Product Description

The AD Software Toolkit is for systems integraters, VARs, OEMs, developers, and serious programmers. Design applications using data acquisition and control hardware to create Virtual (PC) Instruments. The AD Software Toolkit is a library based on the Microsoft & Borland protocols for optimizing the functions of the Lab Master Advanced Design (AD). It is linkable with current version of Microsoft, Borland, and other compilers that support this standard. Source code for the library routines and example programs are included.

AD Software has foreground and background routines. Background routines occur simultaneously with user's application code. Foreground routines return after the assigned task is completed. Hardware interrupts are implemented to service a foreground or background process. Functions range from simple building blocks to complex routines. The Borland C complier is recommended for re-compiling the library.

Key Features

Callable Library
Source Code Included
Working example applications (i.e., stream data to disk, scope emulation)
Supports Extended Memory protocols

Analog Input Processes

Sample one channel in foreground
Reload (map) the Channel/Gain Array.
Setup system for Sweep routines
Perform background sweep (single or repeating) using specified buffer
Return status from background process
Abort background process restoring system conditions
Inform background process that a trigger was detected
Foreground sweep(s) - simple and complete
Foreground triggered pre/post circular buffer
Threshold detection on one single either within a background sweep or as a foreground trigger

Analog Output Processes

Single point output of one sample
Setup system for Sweep routines
Perform background sweep (single or repeating) using specified buffer
Return status of background process
Abort background process
Foreground sweep

Utility Functions

Allocate/Free a memory buffer (low memory or Extended Memory) for DMA transfers
Transfer data To or From the DMA buffer and a separate application buffer
Reload DOS clock from real time clock
Initialize the hardware and establish parameters
Set/Reset hardware interrupts

Digital I/O Processes

Get a sample from a digital input channel
Output digital value to a channel
Continuously sample from one digital input channel, returning when bit changes.
Monitor digital lines form changes in patterns

Counter Processes

Count events (TTL pulses)
Determine frequency of events per time unit
Determine interval between edges on two signals
Output one or more pulses or square waves
Count up/down events

Programming Examples

The AD Software Toolkit comes with working applications created using the AD Software Toolkit. Each application includes source code. Use the applications as is, incorporate the programs into your own custom project, or modify the programs to fit your needs.

The applications include:

Stream data to disk files using one of two examples. One uses a large Extended Memory buffer to store samples and then transfers them to disk at the end of sampling. The other uses a circular buffer scheme to stream data continuously to disk.
Oscilloscope emulation is provided by a program that has data acquisition, storage, and file replay capability, with optimized graphics, a simple uses interface, and multiple triggering options.

Also, a DOS character driver allows access to AD library functions from any software that can open files to sample data or issue commands (e.g. spreadsheets, interpreted BASIC). Also included is a command line interpreter.
