Basic battery capacity meter, which only reports basic battery data
|

via ADC channels and optionally indicate that the battery is full by
|

polling a GPIO line.
|
||||
|
||||
The voltage is expected to be measured between the battery terminals
|
||||
and mandatory. The optional current/power channel is expected to
|
||||
monitor the current/power flowing out of the battery. Last but not
|
||||
least the temperature channel is supposed to measure the battery
|
||||
temperature.
