7 - Conclusion
As shown in previous chapters the F2812 performs really well in this type of applications, and
the Link- and Target- package for Simulink makes it a very powerful tool with literally
limitless opportunities.
It’s when using Simulink that the eZdsp F2812 shows its real strength. An application that
may take hours or even days to write using conventional coding, can be easily implemented in
mere minutes using Simulink standard modeling blocks and a few special blocks for the DSP-
specific features.
Truly, the ease of transferring a model in Simulink onto the hardware once all obstacles have
been avoided is the systems biggest strength. Included in the appendix of this report is a users
guide and some notes for beginners.
The relay algorithm chosen to emulate the needs of power grid applications was implemented
without any apparent obstacles and once again shows just how user friendly the system is.
The twin DFTs extracted two pairs of amplitudes and phase angles – the break criteria was
governed by a pair of simple relay blocks, band-pass filters, but could just as well been of
derivative nature should one require a more intuitive fault detection.
7.1 - Further work
The F2812 supports Ethernet connectivity, though there already exists custom cards with
connectors already present, it could be interesting to investigate how much work would be
required to add this feature to the eZdsp F2812.
A small LCD-screen would make a great addition to an already excellent platform. Of course,
both this and the Ethernet interface mentioned above should have custom blocks added in
Simulink to maintain the ease of use that characterizes the rest of the system.
