Arming via switch

[Reddog]

I was wondering if someone could explain how to select the switch for arming?

[Carsten Böhme]

on tx, map a switch to a channel
in inputs, set 'arming' to that channel, leave neutral in the middle
select 'switch' in arming settings

becareful your failsafe!!! I use DSM2 TX and RX with OPENTX, when signal lost or RX not working, it will auto armed!! maybe is my setting problem(default setting), just make sure your setting is correct.

Can you check when you turn off the transmitter if your ManualControl.ControlSource goes to Failsafe?

i actually have a little problem like this, although i have successfully mapped my Tx with the GCS, on all 4 channels, setting the ARM channel, e.g roll left while throttle down, doesnt work. i have to set it always armed to get the motors spinning and flying

[peabody124]

I would STRONGLY STRONGLY advise not doing this and getting things configured properly. You are losing a major safety feature by not having the ability to quickly disarm. Not to mention the danger of it always being armed.

When you say "successfully mapped my Tx with the GCS" do you mean you are flying with the GCS in control instead of a transmitter?

[Francis Velasco]

i mean my physical Tx is recognized by the GCS and im able to properly set the necessary values when using the radio wizard, using a WFLY tx. my Radiolink Tx didnt fully sync, it couldnt get it to recognize the yaw.

I agree about the safety feature of arming/disarming on the fly, but i cannot get the feature to work, ive selected all the options and none help me arm or disarm the the quad, it only works if i set it to always armed.

it would be cool to use a switch to arm/disarm

[peabody124]

I'd like to understand why normal arming isn't working for you. My guess is you need to recalibrate your transmitter to the GCS - perhaps you shifted a trim too much or messed with a dual rates switch.

When you set it to arming on roll or whatever and then put it in the arm position look at the ManualControlCommand. You should see throttle < 0 and the roll value < -0.95 (IIRC)

[Evan Wong]

i just check again, when transmitter off, failsafe is working, ManualControl in warning state, no problem. 

when i try to cut off the RX power, then it auto armed! but it only keep about 10s, after will disarm again, is it my setting problem?

i use this RX http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idproduct=31224 it two type failsafe can set, i set it the preset mode, when signal lost, back to preset position.

No, it sounds like you found a bug then - I'll try and check this ASAP.

>you found a bug

I recently had one occasion where a plane was armed with the switch off. I had just plugged in the battery and taken it up for flying. Attributed it to a Tx glitch or user error and do not remember what I did in which order.

[peabody124]

DSM2 doesn't cause this problem (because it nicely says when data is invalid) so I can't replicate it but I think I see how some receivers could cause this bug. I think this should be fixed in this branch:

https://github.com/TauLabs/TauLabs/pull/1095

I'd appreciate one of you that can replicate this problem saying if the fix works.

[Carsten Böhme]

I cannot reproduce the condition. As mentioned before, I do not remember the details.

[Reddog]

I was setting up arming with a switch last night and I found it a bit confusing, with a bug as well.

Is the arming switch the 9th channel or one of the 8 input channels? For example accessory2 is also the arming switch?

The arming switch only works properly if when it asks you to center your sticks/dials/switches you flip the arming switch (2 position) to max value. If you put it on min value it does not work.

[peabody124]

I'll need to look at the wizard aspect (and your other issue with the wizard, thanks for reporting that). To answer your question, though, no it is an additional channel. Not an accessory one (although you _could_ assign it to both I suppose).

You can see this on the Input config page http://imgur.com/NeI4MPp it is listed bellow the accessory channels.

[Reddog]

Great, thanks for getting back to me. It seems that if you skip the accessory2 and create an arming switch, it is linked to accessory2. In saying this, that might not be the case as I did the wizard a few times and it might have been left over from a previous run.

[peabody124]

Yeah I think you pointed out a previous bug that the wizard doesn't wipe the configuration first. Thanks for reminding me. That totally had slipped my mind.
