I have a Navio2 on a Pi2 with the power module from the store.
I followed the docs on how to set it up in APM Planner 2.0 but still I get zero measured voltage.
Could it be broken or is there some way I can test it?
It powers the Navio and Pi just fine.
Thanks

Hello there!
It is necessary to provide following information to get help:
I’m using a Navio2 with a Pi2 with image: emlid-raspbian-20160718.img and ArduPlane V3.7.1
I have connected a 4S lipo to the power module sold on the emlid store and according to the docs
selected the Pixhawk power module 90A in APM Planner 2.0 while connected to ArduPlane over UDP port 14550.
The problem is that I still get measured battery voltage as 0.
So far I have no servos or RC/radio gear connected.
Just a Wifi adapter.
I tried the ADC example and got:

could you check that in full parameters list battery voltage and current pin are 2 and 3?
Not sure if I’m doing something wrong, but APM Planner doesn’t show Full Parameter List, only
Standart Parameters, and here
BATT_MONITOR, BATT_VOLT_PIN and BATT_CURR_PIN
are always set to Disabled even if I change them manually and restart ArduPlane and APM Planner.
Where does ArduPilot store settings and parameters on the Pi?
How do I ensure that parameters changed in APM Planner are stored on the Pi?
/Jacob
click on file (upper left) and click advanced mode;
now full parameter list appears and you can check the pin numbers;
settings are in /var/APM/ArduCopter.stg
in full parameters list there is a button “write to”
Not sure what I’m doing wrong, but Full Parameter List is empty.
Tried refresh, reset to default and reboot and download.
Also checked: /var/APM/ArduPlane.stg
It’s 16kb but almost all zeros?
/Jacob
are you connected to your Navio?
u usually only need /var/APM/ArduPlane.stg after major upgrades to delete it;
Yes, UDP port 14550
what happens when you click refresh parameters?
a green square shows you that heartbeat is being received; also you can see your navio moving in the hud?
Everything is online, Heartbeat, GPS, Gyro, etc.
When I click Refresh unde Flight Controller it says: no params to write
When I click Refresh under Download Parameters nothing happens.

Okay…
I made a fresh image, and using Mission Planner (Windows 10) on my laptop i was able to get the full parameter list and set:
BATT_MONITOR=4
BATT_VOLT_PIN=2
BATT_CURR_PIN=3
Wrote params and restarted ArduPlane.
Now I have correct Voltage in APM Planner 
(OS X)
(But still no full parameter list in AMP Planner???)
/Jacob
delete ArduCopter.stg and reboot;
if that doesn’t solve your problem, please:
post a screenshot of APM’s full params list;
post a screenshot of command line starting ArduPlane;
Edit: ignore the above;
make sure you have latest APM planner or reinstall;
I’m not sure how to purge settings on OS X.
I tried deleting ~/apmplanner2 and reinstall but some settings remain.
