ACCES32.LIB for LabVIEW 7.0 The ACCES32.LIB for LabVIEW is a wrapper for the ACCES32 driver written for use with ACCES I/O products. The library includes six Virtual Instruments (VIs) that each use one of the functions available in the ACCES32 driver. InPortB.vi : reads an 8 bit value from a specified address. InPort.vi: reads a 16 bit value from a specified address. InPortL.vi: reads a 32 bit value from a specified address. OutPortB.vi: writes an 8 bit value to a specified address. OutPort.vi: writes a 16 bit value to a specified address. OutPortL.vi: writes a 32 bit value to a specified address. All of the VIs will return AA55 hex if there is an error. The individual VIs are also available in the VIs subdirectory.
