Developing Your Application
This chapter discusses the software utilities you can use to start developing
applications that use the NI-VXI/NI-VISA drivers.
After verifying your system configuration, you can begin to develop your
VXI application. Be sure to check the
README
file for the latest application
development notes and changes.
Your software includes several utilities to assist you in your system
development. These include Resman, vxitedit, and victext. You can also
access several examples to learn how to use NI-VXI and NI-VISA for
certain tasks.
Configuration
The configuration utilities in your kit are Resman and vxitedit. Resman
is the application that performs VXI Resource Manager functions as
described in the VXIbus specification. Its most important functions include
configuring all devices on the VXI backplane for operation and allocating
memory for devices that request it.
Note
Power cycling resets all devices, so you need to run Resman every time chassis
power is cycled to reconfigure them.
After Resman has detected and configured all VXI devices, you can view
specific information on each device in your system by using the vxitedit
utility. This utility includes a Resource Manager Display, which contains a
description for each device, including each VXI device’s logical address.
Although the VXIpc controller is configured in hardware and software for
the most typical configuration, you may want to change the default settings
to best suit your application. Use the VXIpc Configuration Editor or the
VXI/VME-MXI-2 Configuration Editor available in vxitedit to view or
change the settings for your devices.
