Before I spend 50 hours reading items that may not apply I thought someone could help point me in the right direction.
With Venus on a Pi and targeting and RV how do I interface with external devices. I'll have...
- lithium bats
- house bat
- lights (may need to access code for this)
- line power
- solar panels
My basic understanding is the PI has a usb and people use dongles to convert to can.* but I have not can.*. Just stuff, some serial, some just voltages and currents etc. Are the GPIO's accessible on the PI through some drivers code on the Venus? Do you have to roll your own display info, DB, data storage, etc. or is the venus just defaulting to what the manf put together for their equipment.
If someone could clear it up in a couple of sentences I'd appreciate it. It will save me lots of time as I have the basic work to do on the RV.
