Added ability to rescale rssi input voltage. Useful for receivers like FrSky which have 3.3V output.

merged, sorry for the delay, thanks for the contribution! Can you double check that master looks ok? I added a minor change to add a check that the rssi_range is not zero to avoid a divide by zero.

hello Randy,
I just loaded AC 3.1 and i cant find the rssi_range parameter anywhere. did it make it into 3.1 which is published on mission planner ?

hpcre,
No, it went in just after AC3.1 so it won't be out officially until AC3.2 but it'll make it into the next release candidate. I suspect that the 1st AC3.2 release candidate will be out within the next 2 weeks. It will primarily be for the Pixhawk people but anything else that has made it into master (like this change) will also go out.

Hey Randy, thanks for the update.

Hi, any news for the AC3.2 RC? it isn't in the 3.1.1 RC2 ... :-(

[rmackay9]

No, it didn't make the cut-off for AC3.1.1. It'll be out for AC3.2. Sorry!
