Who I am
not familiar with layouting WIki-pages as you can see from the non-existant layout of this page
43 yeras old. I have a degree similar to a bachelor (Dipl.-Ing.) in mechanical engineering. My daily work is working as a teacher in mathematics and metal technology (basic things about milling, lathhing, water-heatings steel-construction).
I'm a "hobby" electronic "engineer". No formal examination but quite a good amount of knowledge.
I have software-developing experience with turbo-pascal (long time ago) and delphi. I worked several years for a company as a softwaredeveloper for industrial controls of engraving machines.
I write code for the microcontroller called propeller-chip [1] from parallax inc.
This is my favorite microcontroller for the following reasons:
development environment is very easy to setup:
1) Start Setup.exe for FTDI-driver
2) Start Setup.exe for Code-Editor.
Start coding in a high-level-language called SPIN (similar to C or delphi) or propeller-assembler PASM
EACH PASM command can be executed conditional to flags
Code runs completely in RAM so selfmodifiying code is possible.
32Bit at 80MHz clock
Chip has TV-graphic and VGA-graphic "on board". (add some resistors and you are done)
Has 8 CPU-cores than can run independant from each other
So no interrupts for catching external events nescessary.
absolute deterministic behaviour of the PASM-code.
Very flexible as all interfacing is done by software.
