warranty for eventual bugs. If you find any, please contact me and sometimes I can fix
Datalogger for VC840 multimeter
for VC840 and UT60E
allows display and logging of multimeter values, can copy them to the clipboard and
thus offers the possibility to paste them into EXCEL or whatever.
(J.C. Feltes, based on readout code by H.J. Berndt)
MTDRAW is a simple drawing program especially useful for drawing electrical circuits.
It has the possibility to put reusable macros into a library
Easy drawing of coordinate systems, sine waves and any curves.
The drawings can be imported via clipboard to any WINDOWS application.
(J-M. Frantz and J.C. Feltes)
Some drawing libraries
AVR timer calculator
AVR timer calculator calculates the Compare register values necessary to achieve a certain timer interrupt time.
Needs a Python 2.x installation with Tkinter (for the GUI)
I programmed this little application because I find it useful, and as an exercise in Python GUI programming.

My (very uncomplete) summary of FreeCAd scripting in Python
From draft to G code A short summary for the Path Module of FreeCAD 0.17
Topological scripting The principles
Creating objects with SolidPython in FreeCAD. How to start SolidPython allows us to do OpenSCAD things, with a friendlier Python syntax,
From drawing to CNC: an overview
CAM: Generating toolpaths with HeeksCNC
LinuxCNC Konfiguration für High-Z S-400
LinuxCNC: Generating a signal on the parallel port with HAL
Heeksfunctions: generate 2D objects, pocket, profile and drilling operations for HeeksCAD
The Pythonic approach to 2.5D CNC milling. All objects are generated by code (as in OpenSCAD).
This allows the use of variables, for loops and calculations in the drawing script.
The only thing to do in HeeksCAD is "Menu - Post process" to get the G code for the machine. Collaboration welcome!
