SliderWriter, Capacitive Slider/Button Maker for OsmondCapSense_to_Osmond.html
MC34063 Boost Converter Calculator
Simple calculator with worst-case output voltage margin calculation. MC34063_boost.html
Schmitt Trigger Calculator
A resistor calculator for inverting and non-inverting Schmitt Triggers built with Comparators (Push-pull output).SmTrig.html
LCR Library Generator
Helps generate libraries of components with systematic part numbers. Useful for resistors, capacitors, inductors, and diodes. It generates a spread sheet with up to three manufacturers’ part numbers (two second sources), values, and device markings per rules you set. There is also a script for import into DesignWorks.

1 Wire Keypad Generator
Resistor selection for a resistor divider keypad using a single A/D input. User enters resistor characteristics and temperature range to assure robust design. Generates C code for reading keyboard.1-wire_keyboard.html

FPGA to Osmond

Generates both text for DesignWorks’ Auto Part Gen tool and a footprint for Osmond PCB layouts. Has not been tested with recent versions of Xilinx software.

BLAST - Basic LIN Application Support Tool 
With the aid of a USB-to-Serial Port Adapter and an RS-232 to LIN adapter, allows monitoring and sending of LIN messages.Blast.html
Serial Analyzer
Monitors serial communications and
hardware protocol lines.

PPSC - Programmable Power Supply Controller 
Takes a CSV file with voltage and time columns and sends them to a programmable power supply. Many programable power supply models can be supported. Three examples included. PPSC.html

This is a collection of electronic engineering software tools and projects. I have written most of the desktop software in XOJO so it is easy for me to build Apple Macintosh (OS X), Windows, and Linux versions of most of them. They are not polished works of art, but they get the job done, and are here for you to use as long as you do not sell them. If you are a consultant, you are free to use them in your work as long as my software is not part of your deliverable. If you do not find what you are looking for here, check out this list of tools from others.

NOTE: Use this software at your own risk. I assume no liability what-so-ever.
