Low level software development is replaced by an intuitive visual programming system that harnesses all the power of Microsoft Windows - graphic user interface (GUI), access to more host memory (16 megabytes), multi-tasking, and inter-process communications using DDE. Applications of PC-414 include highly concurrent system testing, process monitoring and control, telemetry, radar, sonar, acoustics, DSP front end quantizer, education, and research.
The PC-414 LabVIEW package from DATEL consists of a set of inexpensive VI's for low level control of the board. These integrate into the LabVIEW package which the user must purchase from National Instruments. Once installed, these VI's appear as icons on the LabVIEW menues. DATEL's VI's are offered in two versions. Model PC-414LV is the executable binary-only configuration which can be fully integrated into the user-written block diagram. Model PC-414LVS is the full source to model PC-414LV and also includes all binaries. The source code should be considered by a programmer who wishes to extend or modify the existing VI's or just wants to more fully understand their operation.
LabVIEW's feature-rich program development system combined with DATEL's library of VI functions for the PC-414 provide the essential building blocks to create any conceivable LabVIEW applications.
Graphical programming works like a flowchart - when the flowchart is accurate and complete, the program is done. PC-414LV off-loads as much programming as possible into the LabVIEW environment so the user has maximum control.
It creates a library of fast, simple, highly modular VI functions for the PC-414 that do not sacrifice board performance. The user builds VI's to configure PC-414 acquisition hardware, process the data, and ultimately display and store that data without writing programs. Similar VI's can be created to update the analog output and to read and write the digital I/O port.
