About Me

My name is Roger Meier, and I am NOT a professional programmer. Writing my own programs is a hobby that I picked up when I couldn't find any decent (if at all) freeware or shareware for certain tasks for which I wanted to use a computer.
I picked Xojo (formerly REALBasic) as my language of choice for several reaons, including its structure, its 'object-orientness', its capability to create executables for Mac OS X, Windows, and Linux Platforms, and last but not least for its fairly large and helpful user community.
Here I'm hosting open-source code that may be generally useful. Current open-source projects are listed in the table below. Simply click a project name to download the project archive.

I have also created a number of small Freeware Applications and Tools that you might be interested in.

Open and CoolTerm 5. Connect to your serial port should look something like COM3 or USB 1121. Set the baudrate to 115200. Select the Terminal tab and make sure your the line Mode option is selected under Terminal mode. CoolTerm is a tool that's geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers etc. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system/platform without restrictions.

Current Projects

Project Name	Version	Description
OpenSimpleTerm Source Code	v1.1.2 5/04/2021	A bare-bones version of CoolTerm released as an opensource project. Written in Xojo.
OpenVisualTimer Source Code	v1.0.0 7/13/2020	A previous version of VisualTimer released as an opensource project. Written in Xojo.
Complex Utilities Source Code	v1.0 7/9/2006	A REALBasic class that implements support for complex numbers with Double precision. Standard operators are overloaded, and many other mathematical functions are implemented to work with complex numbers. Comes with a module with wrapping functions for convenience, as well as a test harness for quick verification.
DataPlot Classes Source Code Screenshot	v1.4.3 2/4/2019	A set of Xojo classes for plotting data, Y versus X. Useful for Math, Engineering, or other scientific disciplines. Includes a User's Guide and several examples. NEW: Cross-platform Hi-DPI support. Contributions from others: Examples, additions, etc. from users in the community. Note: These projects are not actively supported. Please contact the individual contributors for questions and information. DataPlot Zoom: Interactive zoom, by Hakan Nyberg Candlestick and Piechart: Two additional Classes by Leonidas Brasileiro
SmoothTrace for DataPlot Classes Source Code Screenshot	3/25/2015	A modified version of the Trace Class (part of DataPlotClasses) to demonstrate a way to draw smooth traces. NOTE: Lines styles other than solid as well as the TraceClick, MouseOverTrace, and MouseDownTrace events are not properly supported by this modified version.
FFT Suite Source Code Screenshot	v1.0 10/19/2007	FFT Suite is a REALBasic Module with a set of methods related to FFTs. Its FFT functions implement the Cooley-Tukey Algorithm for real and complex FFTs. Also included are methods to generate various window functions. Requires Complex Utilities. Autocad for mac torrent. The included example Project FFT Demo requires DataPlotClasses.
DigitalCircuitSim Source Code Screenshot	11/14/2006	A real time graphical digital circuit simulator with a library of logic ICs. It also includes a fully functional timing simulator although no file I/O has been implemented for it yet. Circuits can be copied and pasted into the timing simulator (as text). Stimuli have to be edited as text. Requires DataPlotClasses.
