Massive GIPO Interface - Conversion to IoT Framework

Massive IO for IoT - Phase One

FAC massive IO framework is an interface board (DIO120) and bus that supports thousands of optically isolated high current control points. The existing DIO120 connects to a PCI GPIO interface card running in 8255 PPI mode.

FutureHouse is currently re-designing primary interface to support mounting RaspBerry Pi as master microcontroller. Boards can be connected together via parallel bus or spread over a wide area using ethernet discrete io meshing protocols.

Project progress will be posted here as material becomes available.

Phase One

• Illustrate design principals of DIO120 - completed

• Provide detailed documentation - partial

• Design showcase and feedback - in progress

Phase Two

• Redesign interface for Raspberry Pi

• Rewrite current PC based .net driver to operate on Raspberry Pi 

• Port master control logic

• Test operation using 6 boards connected to expansion bus (720 control points)

Phase Three

• Production changes to interface board

• Port Device Sphere mesh services and library

• Test operation using 8 boards on one location and 6 boards in a remote locate for a total of 1680 control points.
