Marcus Harrysson commented on Gary McCray's blog post Great deal on a 3 axis gimbal with Alexmos controller
"Im looking how to connect pitch and yaw to my RX so I can trim/tilt when needed.What do I connect and where, and are there any setting I need to edit for this?

Thanks in advance :)"

"I know what you mean, you can connect a BT-module as it was the 3dr telemetry-link :)
This in parallell with the teensy, but BT-module would need both TX and RX while teensy would only need to connect to the APM-TX

So no need for additional teensys…"

"You could just run both in parallell, just dont hook up tx to the teensy if I remember correctly.
Teensy = send data only, and the BT-module both send and recieve.

Double check this though."

"Select the correct chipset in the dropdown menu? Correct port etc?

Only times I have gottens errors are if the code is bad (this code isnt), if missing libraries (are you?)  and wrong chipset selected (Tools > board >teensy3.1   is the correct one)"

"Perhaps the issue I had, after updating to AC3.2 and reset. Resulting in no data recieved on the taranis yet the teensy transmitting but no data at all. Some values were changed and then changed back and voila, data again."

"Using a teensy? If so, got the extras needed for the software? Otherwise errors when verifying :)

IF I understood the question correctly that is :)"

"I am trying to edit some code to Catch the call that shows all cell-levels and not just cell_min.
Anyone know the call to make? To get the function for cell_min its :  cellmin=getValue(214)

Should be a similar way to get "cells" that is available…"

"Tried all and finally did the powerpanel changing just Before you wrote and voilá!

A final Q if you can answer, is it possible to call "cells" and put in the powerpanel?
The one showing every single cell, its available if you go through pages in…"

"BTW, is it possible to edit the code to just have lipo-voltage and the cells instead of wattage etc? :)"

"Ahhh I need Another sensor for the apm?Then I know why it doesnt work :)  Thought it somehow could sense things without one using teensy,
but now I know.  Guess Ill have to figure out how to connect a current sensor on my version of APM then :)…"

But how to get mAh-usage showing and such? 
The F G H I from  https://raw.githubusercontent.com/wolkstein/MavLink_FrSkySPort/s-c-... I see voltage and cell-min and I Think I did the config correctly with Wh but…"

"All ok again, found an error in my network though, but I am afraid to hook it up now :P

Is there a certain order to connect? Lipo main first, then balanceplug? Or doesnt matter?
And I should have a common ground using a single battery yes? :)"

"I kind of killed my teensy when doing something wrong on the network and redid it just nu, can you instruct me how to see if all good?  Measurements to make etc? :)

Say Cell1 lines on the network has a certain resistance in the end etc?"

"OR flash the s.bus firmware on the APM if possible (seems not all non-"original" itterations of it can do it)"
