Thanks Matti,
I'm on slack, but that moves too fast to be able to get me going in the correct direction.
So far, I've built two N2K Gateways, which I've given to buddies of mine. I have one SH left which I'm experimenting with (will get some extras from you soon).
I've successfully loaded SensESP. Nice work!
I want to begin with simple tank level sensors. My issue is they are still connected to my 12 volt system and I know that will required stepping that voltage down. For now, I'll just remove the 12 volt and attempt to go from the hat to the sending unit to keep things simple. I'll use the "fuel level sensor" as a base "Main.cpp" and make adjustments from that. I assume that I'll need a ground to all sending units and and bring the positive side back to the SH32 and land them on GPIO pins 12, 13, 14, 15. Then it should be a simple matter of defining the SK paths to use and the pins to read in the software.
Correct?
Now, the SH32 will sample those reads to the equivalent of 4,096 different readings. I see in the sw that I can set a low and a high, but I'm a little lost in what to start with, except 0 and 4096. I'll eventually pull the senders and operate them to see where I'm at, but am a little unclear what the ADC would out put as a value, if low voltage is input on the analog side.
And if I decide to leave them on the 12 volt gauges they are on, I'll need a voltage divider to lower the voltage to 5.5 and under.
