getValue(source)

Returns the value of a source.
The list of fixed sources:
OpenTX Version
Radio
2.0
​all​
2.1
​X9D and X9D+, X9E​
2.2
​X9D and X9D+, X9E, Horus​
2.3
​X9D and X9D+, X9E, X7, Horus​
In OpenTX 2.1.x the telemetry sources no longer have a predefined name. To get a telemetry value simply use it's sensor name. For example:
Altitude sensor has a name "Alt"
to get the current altitude use the source "Alt"
to get the minimum altitude use the source "Alt-", to get the maximum use "Alt+"
@status current Introduced in 2.0.0, changed in 2.1.0, Cels+ and Cels- added in 2.1.9
Parameters
source can be an identifier (number) (which was obtained by the getFieldInfo())
or a name (string) of the source.
Return value
value current source value (number). Zero is returned for:
non-existing sources
for all telemetry source when the telemetry stream is not received
far all non allowed sensors while FAI MODE is active
table GPS position is returned in a table:
lat (number) latitude, positive is North
lon (number) longitude, positive is East
pilot-lat (number) pilot latitude, positive is North
pilot-lon (number) pilot longitude, positive is East
table GPS date/time, see getDateTime()
table Cells are returned in a table (except where no cells were detected in which case the returned value is 0):
table has one item for each detected cell:
key (number) cell number (1 to number of cells)
value (number) current cell voltage
Notice
Getting a value by its numerical identifier is faster then by its name. While Cels sensor returns current values of all cells in a table, a Cels+ or Cels- will return a single value - the maximum or minimum Cels value.
