Installation and Startup Procedure
#1
In short, I haven't found one.

I have the tinypilot connected to the large motor controller. It is connected to the motor, a Octopus 2l 12v hydraulic pump. and to my homemade rudder position sensor.
  red -> 680 ohm -> 5k precision pot ->black with wiper connected to yellow, 0.1v when full starboard.

I did the gyro calibration, but did not lock the calibration.
I set the 'Boat is level"
I set the motor max current to 6 Amp.
I did the rudder calibration. But I cannot find a place to view the rudder position.

In standby mode, the small course correction buttons move the motor some.
  I get FAULT or SYNC or SATURATION errors.

Next I connected a tablet by WiFi to pypilot and went thru the calibrations again.
     still no rudder position.


Next I installed the pypilot_pi in opencpn on my laptop
    (my navigating opencpn runs on an Orange Pi PC2, AIS and GPS are wifi broadcast on ships wifi router)
And connected it to the pypilot's AP.
    The plugin is enabled but the preferences button remains grayed out. Is this correct?
I added rudder position to opencpn's dashboard.
    Nothing shows, always centered, even when I manually turn the rudder.
I clicked on the pypilot_pi config tab, and checked all 3 boxes under opencpn settings
I checked the signalk settings
    still no rudder position display
I attempted to manually config connections-> TCP-20220, bi-direction, sentences but no change, so removed it.


I must be missing something??

I almost forgot:
opencpn 5.0, pypilot_pi 0.9, latest image for tinypilot from pypilot.org

I almost thought I found it, but no. The voltage was 0.4-1.25
So I added a 3.8k on the high side, so now the voltage is 0.09 - 0.78
now it is +5v -> 4.5k -> 5K pot -> GND

opencpn will move the rudder, but still no position indicator, always 0.
