Taranis QX7S / OpenTx 2.3.1 / Crossfire Alt & Hdg problem (Matek F765)

Hi, I'm using a Taranis QX7S running OpenTx 2.3.1 with Crossfire Tx (full) and I'm setting up a wing with a Matek F765 running ArduPlane. All softwares are up to date. Specifically, I'm asking about what is displayed on the Taranis TELEMETRY page (12/13). Hdg (F765 compass) and Alt (F765 baro) are n...

Re: Scale the resultant signal of all other mix signals, resultant signal changing sign

Depending on exactly what you are trying to do (e.g. what you wish to scale by, constant or variable), you can use three mixes: Add Weight(0), offset(100) Multiply - whatever you need Add Weight(0), offset(-100) If, say, using a pot for the scaling, you could try two mixes: Multiply S1 weight(50) o...

Re: Scale the resultant signal of all other mix signals, resultant signal changing sign

@Kilrah - I tried that. The problem is that you end up scaling relative to the x-axis - which is fine if there are no negative values. It does not give the desired effect if there are. What I'd like to achieve is scaling relative to a line parallel to the x-axis at y = -100. I tried simply offsettin...

Re: Scale the resultant signal of all other mix signals, resultant signal changing sign

I see where you're going by making everything in the positive domain, but surely this will offset the whole channel making my multirotor unflyable..

Scale the resultant signal of all other mix signals, resultant signal changing sign

Hi, Can I use a mix to scale the resultant signal of all other mixed signals *when the resultant signal goes from a negative value to a positive value*? To clarify further: OpenTx uses signals going from -100 to +100. Scaling a signal would be easy if it were 0 to 100. But it isn't.. The origin is (...

Plotting stick position (input) against channel pulse width (output) as a graph

Hi all,

Can this be done with OpenTx? After all the mixing is said and done, I need to be able to plot stick position (input) against channel pulse width (output) as a graph. Let's say we have stick position on the horizontal x axis, and channel output on the vertical y axis.

Please help!

:)

Re: Adjustable 'centre' for mini-quad throttle curve - during flight

That's fantastic. Thanks Mike. Very much appreciated!

I could graph this manually (throttle stick deflection on x (horizontal) axis v. channel 3 output on the y (vertical) axis, but is there a quicker way? Perhaps this is where some Lua could come in handy.

Thanks :)

Re: Adjustable 'centre' for mini-quad throttle curve - during flight

Hi again Mike,

I'm having difficulty programming it into the radio. I'm confused about.. umm.. quite a lot of things. Could you possibly provide me with a file of it programmed so I can examine it to see exactly what's going on?

Sorry about this, but I'm pretty new to programming the mixes.

Re: Adjustable 'centre' for mini-quad throttle curve - during flight

Hi Mike, That looks great! I won't be able to try it till the weekend, but I'm looking forward to it! I studied up on Lua last night (just introductory stuff), but it seems to be quite a simple scripting language. Yes, I saw the warnings about execution not being guaranteed, so I guess that's not a ...

Adjustable 'centre' for mini-quad throttle curve - during flight

Radio: QX7S running OpenTx 2.2.1 Hi all, At the moment, I set up a simple custom 5 point curve for my mini-quad throttle. The middle three points form a line with a 'flattened' gradient, just as if I'd chosen a traditional expo curve. What I want to do is assign one of the control knobs to be able t...

Re: QX7S LBT Tx, Non-EU R9M Module & Non-EU R9 Slim Rx

I have another R9M Module, the LBT version on 868 MHz, and that works fine. It binds with its corresponding LBT R9 Slim Rx. I don't have a replacement Non-EU R9M Module with which to test. But yes, the Non-EU R9M Module's red light does flash at power up, and I can literally hear the RF power when I...

Re: QX7S LBT Tx, Non-EU R9M Module & Non-EU R9 Slim Rx

Yes, that's all done. Currently, I have the QX7S External RF set to R9M, FCC, CH1-16, Mod telem. is checked, RF Power is set to 100 mW. Internal RF is set to OFF.

I can't figure this out..!

QX7S LBT Tx, Non-EU R9M Module & Non-EU R9 Slim Rx

Hi, I am (intentionally) trying to use the following combination: QX7S LBT Tx, Non-EU R9M Module & Non-EU R9 Slim Rx. The problem is I cannot get the Non-EU R9M Module to bind to the Non-EU R9 Slim Rx. All firmwares have been installed (in order) to the most current versions. Is this a case of t...
