Chapter 4 - Programming the Board Introduction This chapter contains information about how to program the GX5642 board using the GXPIO driver. The GXPIO driver contains functions to initialize, reset, and control the power-supply instruments. A brief description of the functions, as well as how and when to use them, is included in this chapter. -
Page 40: Programming Gxpio Boards Using Ateasy
Programming GXPIO Boards Using ATEasy The GXPIO package is supplied with a separate ATEasy driver for each board types. For example, the GX5642 is supplied with GX5642.DRV ATEasy driver. The ATEasy driver uses the GxPio.dll to program the board. In addition, each driver is supplied with an example that contains a program and a system file pre-configured with the ATEasy driver. -

Chapter 4 - Programming the Board Figure 4-1: PXI/PCI Explorer Slot numbers are gathered by PXI/PCI Explorer using a PXISYS.INI file located in the Windows directory. Each PCI slot is identified by a unique combination of PCI Bus and Device numbers. If that file does not exist or not complete with all bus/devices assigned slot numbers, you can assign slot numbers to your PCI slots. -
