Hello,
here are some answers to the recently posted questions:
The development of RTuinOS has been made from scratch. I've tracked the
effort: It took about 90 hours to do the implementation (including
specification, makefile and all the test cases) and about 70 hours to
write the documentation.
I didn't hear about protothreads before and can't compare it to RTuinOS.
DuinOS is the port of FreeRTOS for our micro controller. FreeRTOS exists
for many years and has been ported to many controllers. Actually, it has
been designed to be easily portable to other controllers; this is one of
its major features. Obviously, FreeRTOS is much more mature than RTuinOS,
it would be overweening to announce RTuinOS as a comparable competitor of
FreeRTOS.
The only goal for developing RTuinOS was enthusiasm for Arduino and the
RTOS topic. When I got acquainted to Arduino a few month ago I was really
enthusiastic about the concept which put the ease of use on the first
place. I immediately bought a MEGA board, made some simple experiments
first and looked then for a challenging task. I'm professionally working
with existing RTOSs and took the chance to develop another one.
There's no university background, it's just a leisure time project.
The test cases which come along with RTuinOS have been developed together
with RTuinOS. You call it a proof of concept and this will hit the point.
RTuinOS is new and not proven in practice. There are no real life
applications of RTuinOS so far. If being used in a productive environment
this needs to be considered a major risk. For leisure time projects it
should be alright.
This is the first time I issued self-made software in the net and I'm not
so familiar with the various sites for publishing free software and how to
do. I going to investigate it and notify the Arduino Forum if I find
another adequate upload location. Furthermore, I will take a look at the
Arduino Playground. Thank you for your hints.
Kind regards
Peter
