[Paparazzi-devel] HV LIPO pack and GCS voltage indication

[Chris]

Hi.
I have a question about battery voltage indication for anyone that might 
know.
I would like GCS to show the battery voltage like it does now but not 
from the standard source which i think i ADC_3  but from ADC_1.
I use 10 cell lipo pack and because the voltage is high i use a separate 
psu set to 12V
powering the AP and a resistor voltage divider connected directly to the 
10 cell battery in order to make 50v appear as 3.3 (14.7K and 1K resistors)
This voltage signal is routed to ADC_1.
Unfortunately so far GCS is showing me 12v which is the supply to the AP 
and not the real lipo pack's voltage.
I know about the correction factor etc. but i don't know how to make the 
autopilot
use ADC_1 instead of the standard ADC_3
Is there any definitions that can be added to the airframe file in order 
to achieve this
or i must do some code changes?
