FrSky AD1 & AD2 voltage in hundreths #290

What new feature/ability do you want?

Display FrSky voltages in hundredths of a volt. I am using an LM35 temperature 
sensor on AD2. The sensor has an output of 0 to 1.00 volts dependent on the 
actual temperature sensed. 20 degrees C. is output as 0.20 volts. 25 degrees is 
output as 0.25 volts. When the display is only in tenths of a volt then a lot 
of the resolution of the sensor is lost. This only has to work below 10 volts 
or even 1 volt in my case. If the decimal could be moved over and the leading 
zero removed then that would be even better. Best case scenario would be to 
also change the volt symbol to C for centigrade.

What is the expected output?

Change display for actual input of 0.25 volts or any reading under 1.0 volts 
from 0.2V to .25V and have the ability to move the decimal over 2 places or 
better still to read 25C

What version of the product are you using?

364

Please provide any additional information below.

The initial versions of the FrSky firmware had the volt display in hundredths 
but with the last major revision to the FrSky FW that disappeared.

Is this still a problem? A1 and A2 sould now go to 2 decimal if the full scale 
value is below 10.0.

I was just out flying today with my temp sensor hooked up and voice activated 
by switch. The voice is saying "point two five" for 25 degrees celsius so 
ideally I would like to be able to move the decimal over 2 places to the right 
and have just 25 displayed and spoken. The LM35 temp sensor outputs .01volt for 
each degree of temp between 0 and 100 so that is the source of the problem. It 
is, however a very cheap and simple setup. Most of my telemetry equipped models 
have that temp sensor installed.
