File Tools

  File Tools is LaVIEW a toolkit which helps working with some file types. The list of tools in this toolkit is as follows:

  • Execute File – a couple of VIs for executing one or multiple files. This tool can be used for launching documents or other files as well as executable files.
  • HEXrw – this tool reads and writes Intel hex files as described in Wikipedia. The HEXread.vi is a polymorphic VI. You have options to read 8, 16, 32, 64-Bit files. HEXwrite.vi automatically selects what type of file to create based on address and data size.
  • RW_INI – this tool provides simple VIs for reading and writing of configuration files in ini format. Both ReadFromIni.vi and WriteToIni.vi are polymorphic and allow for different data types to be used. You can choose from boolean, double, integer, path, string and unsigned. Those VIs are not meant for use in loops. They open (create) a file, read or write a single parameter and close the file.

Array Tools

  This is LabVIEW a toolkit, meant for array processing tools. Currently the contents is as follows:

  • LogSort – this tool sorts logically 1D string array. Big part of this tool I found on NI’s forums. Those VIs are sorted a bit, but I haven’t put my copyright in them of course. I replaced the original swapping with a set of new VIs that are capable of sorting strings, containing multiple numbers, numbers with leading zeros, IP addresses… It is a bit slower than the original, but provides better sorting. If you are sorting thousands of strings, it will take some time, but even Windows takes its time sotring files by name and it is not really good at it. The vip file will install 2 icons in your Functions menu under PenoffTools>>ArrayTools>>LogSort: LogSort and LogicSwap. LogSort is the VI that does full 1D array sorting. LogicSwap is a part of the tool and it only swaps 2 strings if need in order to sort them. It can be used to sort 2 strings if you ever need that.

Numeric

  The LabVIEW Numeric toolkit contains a few VIs for numeric operations. The following list shows the VIs you will find in Functions menu if you install this toolkit as a VI package:

LV_Numeric

  • 2’s_Comp_to_Num and Num_to_2’s_Comp – a couple of VIs for converting between decimal and 2’s complement numbers
  • SIprefixConverter – converts a number for use with a specific SI prefix. For example you can use it to convert from nano to base or from kilo to mega or anything else you choose. Both input and output prefix are selectable.
  • x_power_y – calculates x to the power of y
  • y_root_x – calculates y-th root of x
  • NumToNoDecPtStr – a VI to convert a number to a sort of scientific notation, but without using decimal point (or comma). It uses the SI prefix instead. For example you can convert 4523 to 4k523 or 0.025 to 25m. You can also add unit.
