Max altitude

erskyTx runs on many radios and upgrade boards
ersky9x was a port of er9x for use on the sky9x board.

Max altitude

Post by kantacoolwind »

Hi, :D
I use Turnigy 9XR PRO + Frsky DJT module + X6R Rx + variometer(w s.port)
I can get altitude in tx monitor , but I can not get "max altitude"
Please tell me how to set telemetry plogram.

It seems I haven't got anything in the firmware to display the max altitude from the variometer, only that from the GPS altitude.
I've made a note to add this in.
If you want to see the max altitude after a flying, you could turn logging on, then review the log file on a PC.

I got XJT module , X8R RX and Frsky GPS sensor.
I can bind but not get GPS data in my 9xr pro screen.
Is my GPS sensor broken ?
By the way, I can get vario data.

I have found the GPS can take several minutes to obtain its position. Until then, it doesn't send any data. It needs to be outside or it may never find its position.

Thank you ,Mike.

I know that.
When Frsky GPS sensor get Location,that LED is flashing slow .
My GPS's LED will also flash slow several minutes later at outside.

Oh sorry,Mike
I succeeded to get GPS signal on My Tx screen.
It was mistake that I bound by D8 mode.
I must bind by D16 mode.
Thank you.

If you want max altitude, and you have the GPS working, then the GPS max. altitude is recorded, and shown on the LAT/LONG telemetry screen.

MikeB, is this something you've enabled in er9x since this post? This is exactly what I'm looking for for DLG use!

What about with vario /Pressure sensor altimeter?? ;)

Thanks

GPS max altitude has been present on that screen for a long time.

The vario max altitude is stored, but it looks like I don't have any way (currently) of displaying it!

Mike,

When do you think you'll have this value accessible? This flying season, or more likely in 2018?

Check this post: viewtopic.php?f=5&t=10338&p=130024#p130024, for a way of detecting max altitude (or max any telemetry value). It is a bit of a fiddle, but should get what you want now.

Re: Max altitude

Having recently acquired a FrSky High Precision Vario...

Here is another way to display the max altitude from the variometer telemetry data. This uses a model background script to keep track of the highest altitude seen so far. Just a few lines of script code will do the job:

altitude = getvalue( "Alt" )
if maxalt < altitude then maxalt = altitude
if getvalue( "CH17" ) > 0 then maxalt = 0
settelitem( "Cus6", maxalt )
stop

"Cus6" is used in this script to display the max altitude on one of the (two) custom telemetry screens. A scaler may be used to round and/or truncate the "Cus6" value, while renaming the data if so desired. Of course, maxalt could also be rounded/truncated in the script itself, before assigning its value to "Cus6".

CH17 is used to reset the max altitude when needed. The CH17 mixer might look like: CH17 +100% FULL switch (AIL). (This produces channel values of either -100 or 100, as determined by switch AIL in the mix line.)

The script was bench tested on a TGY9X/AR9x with an XJT module, running (test) firmware version ersky9x-pd4r222. Rx's used were an RX6R and RX4R. The script worked without apparent problems on said hardware.

Other maximum (and minimum) telemetry values could equally well be displayed using a similar model background script. Three cheers for scripting then, thank you Mike!

Tony

Edit:

As Mike pointed out, the status of a switch may be accessed directly using the getswitch function. There's no need then to get the value of CH17 in my model script, in order to detect the status of switch "AIL". Because I want to reset maxalt when getswitch( "AIL" ) returns 1, the third script line becomes:

if getswitch( "AIL" ) then maxalt = 0

Wish I would have thought of that myself!

I recently added the ability to use a custom name for the Cus1 to Cus6 telemetry items. Go to the Telemetry index and select "Sensors" from the popup.

You should be able to read the switch state directly (e.g. getswitch("AIL"), rather than use CH17. To be general purpose, you may also use sysflags() to find out the type of radio, bit 5 of the returned value is set if it is a FrSky type radio with switches SA, SB etc.

Nice example of a background script.

Thank you for your comments Mike. Being able to rename Cus1 through Cus6 is yet another lovely feature in erskyTx. I had found it a while ago and then forgot all about it...

Regarding switch state detection: but of course, silly me! I shall repent by reading, and memorizing, your script.pdf document ever more assiduously, and by editing my original posting to point out this much cleaner approach.

Now on to setting up my new S6R receiver. Thanks for all your work on supporting it through S6R.bas and the S6R configuration menu in erskyTx.

Best Regards,

Tony
