  1. Serial Mouse Driver for LabVIEW

    Author:
    Eric Olson
    --see readme file for email address
    Description:
    This driver is an implementation of the Microsoft two-button mouse protocol, for using a serial mouse or trackball. It polls a specified serial port at a specified rate, and reads any data waiting there. This has been tested under LabVIEW versions 7.1.1, 8.0.1, and 8.20 under Windows 2000 and Windows XP, and under LabVIEW Real-Time 7.1.1 and 8.0.1.
    This driver contains components created using the dqGOOP toolkit to enable object-oriented programming.
    Note: When using a serial mouse under Windows, it is important that Windows not auto-detect the existence of the mouse (e.g. upon bootup). Otherwise, the operating system will intercept the mouse input and LabVIEW will never see it.
    Dependencies:

    Version history:
    1.0.0:
    Intial release of the code

  3. Game of Life

    Author:

    --see readme file for email address
    Description:
    Conway's Game of Life is a fun little simulation of a group of cells. How new cells are born and how old cells die is decided by a simple set of rules, but can lead to complicated behavior by the entire colony. I've always found this simulation to be interesting and I thought coding it in LabVIEW would be a fun exercise. Comments and critiques of either the game or of my coding style are always welcome.
    The basic rules are simple:
    1. A cell that has one or zero neighbors dies of lonliness.
    2. A cell that has four or more neighbors dies of overcrowding.
    3. An empty cell that has exactly three neighbors containes a new cell in the following generation.
    A thorough explanation of the Game can be found at http://web.archive.o...7s_game_of_life .
    Dependancies:
    This uses the OpenG time, file, and variantconfig libraries. They are not included.
    Download them via the OpenG Package Manager: http://web.archive.o...p?showtopic=233
    Change Log:
    1.0.0: Initial release of the code.
    1.0.1: Include readme.txt in the zip file.
    1.1.0: Added Open and Save As functions (in the menubar). Added an About dialog. Removed the Exit button (redundant to Close).
    1.1.1: Forgot to include the .rtm file in the distribution. Rows/columns now update when opening a .gol file.
