Hi Marco,
I think that your board will be very interesting and I hope to have the RS485 drivers running on Souliss as soon. It will be a nice work, because I shall build a P2P over RS485 and so means have a collision management done at software side.
In Souliss, we are planning the new release by the end of the June or earlier July. The new release shall contain the support for ENC28J60, a new scheduler, anti-theft logics and some general improvement and bugfix. After, we will start for the new features that will include: RS485 drivers, Ethernet-MAC support (to skip IP configuration) and a binary protocol for the external interfaces.
In the while, we are working with the Freedomotic team for the integration between Souliss and Freedomotic, using a plugin on the freeedomotic side (JSON), and I hope to be able to release also a new web-based user interface.
Thanks for sharing your work.
Regards,
Dario.
