i2c to communicate with another standalone gizmo i built
If i release it it'll be a lightweight version simply because companies with which i work wouldn't probably understand that i sell them something i give for free, so it's not yet the moment, i'm still in business relation with some automotive and nautical companies.
Here is the very first unit in which i installed the two units, the media and the automation part.
The tiny gizmo (the one with the green lcd) which has other tasks and the big box containing solid state relays with 90 I/O working with the tiny gizmo.
The 90 ports are scanned within 10 ms regardless of the duty (watchdog inside).
It manages water levels (clean and used), fuel injection of the heather, batteries coupling managment, AC managment, solar panels energy production, warm water for shower and cooking purpose, pumps managment, lighting, several security levels including tracking, narcotic gases detection especially used for burglar and / or attacks while motorhome is a bit away from crowd etc
