(Feature request) Use intenal gps of TX

[stefaanbolle]

I have added a BN-220 GPS sensor via AUX2 to my TX16S. What I actually want to do is displaying my model coordinates using telemetry from Frsky GPS sensor built-in into model using a Frsky receiver (already working with Yaapu HorusMappingWidget). However this widget does not display the location of the transmitter with the newly builtin GPS as home. If this would be possible it would map the model in respect to the transmitter's location.
It would also be possible to show real distance and direction in this case to find model that landed :-) in the corn field nearby.
Does this require major changes to Yaapu HorusMappingWidget for Frsky sensors or is it something that can be easily implemented?
Thanks for considering!

It may be better to use a widget such as https://github.com/moschotto/OpenTX_GPS_Telemetry for this... it's more suited to logging and showing relative distance

I don't know how to program, but I changed some of the code.

function task4HzUpdateHome(widget, now)
  local GPSTable = getTxGPS()
  if GPSTable == nil then
    if telemetry.lat == nil then
      return
    end
    if telemetry.lon == nil then
      return
    end
    if status.homeSet then 
      return 
    end
    if telemetry.groundSpeed < conf.horSpeedMultiplier*0.5 then
      if not status.homeTimerRunning then
        status.homeTimerStart = getTime()
        status.homeTimerRunning = true
      else
        local elapsed = getTime() - status.homeTimerStart
      
        if elapsed >= 500 then
          telemetry.homeLat = telemetry.lat
          telemetry.homeLon = telemetry.lon
          status.homeSet = true
          status.homeTimerRunning = false
        end
      end
    else
      if status.homeTimerRunning  then
        status.homeTimerRunning = false
        status.homeTimerStart = 0
      end
    end
  else
    if GPSTable.numsat > 5 then
      	telemetry.homeLat = GPSTable.lat
		telemetry.homeLon = GPSTable.lon
		status.homeSet = true
	end
  end
end

We need to check what happened.
I honestly stole some code from TxGPStest
