To port the Open Source implementation of the industrial communication profile Ethernet POWERLINK on STM32 Connectivity line family.
Fig. 1 - System Architecture
- STM3210C-EVAL evaluation board.
- OpenPOWERLINK stack. Tested with version v1.6.
- FreeRTOS.org real time scheduler - tested with version 6.0.1.
- OpenOCD On-Chip debug solution for embedded target systems. Tested with version 0.4.0 RELEASE.
- Eclipse open development platform. Tested with version Galileo SR2.
- Versaloon hardware IF.
This demo project was developed by Massimo Trubia (email@example.com) and Alessio Tognazzolo
(firstname.lastname@example.org) for taking their degree in Computer
Engineering at the University of Catania (Italy). I had the pleasure to follow the boys during their adventure... may be they were not so happy to use my Eclipse based IDE during this time! They are good beta-tester! :-)
So I deci
ded to write this web page to show their work and to make them my personal congratulation.
The Multi-Tasking API layer provides a system level service in order to use the POWERLINK stack in the multi-tasking environment provided by FreeRTOS.
Fig. 2 - Multi-tasking API
A generic user task interacts with the stack trough the multi-tasking API That serialize the access to the openPOWERLINK task, as shown in Fig. 2.
The openPOWERLINK is a project designed for a PC environment that has less limited resources than an embedded system. Under this scenario, the most critical resource of STM32 was the SRAM. Its limited dimension has not allowed to include the lwIP stack in the demo project and it was also needed to cut off some openPOWERLINK components.
Massimo and Alessio have published their work on Internet. Feel free to look at the following web page for more information:

Questions, Suggestions, Bugs, and...
Every feedback is welcome. If you have a suggestion to improve a demo or
the web pages, it's ok. If you found a bug in a demo, please let me
know. If you have an idea to improve a demo, I'm pleasure to discuss
about it. If you have any questions about a demo, I hope to have the
answer (by asking to Alessio and Massimo)!
