Well crap. I upgraded my 9x to Frsky just to get PPM.

I agree. I would rather just give you a couple bucks.

What kind of glitches?

signal15

Anyone?

signal15

Anyone know how to physically connect an Frsky receiver to get PPM to the MW board?

Some of the stuff I read over mentioned 3.3v and the risk of frying something.

Acrotrainer mode is now added to shared. With #define ACROTRAINER 200 . It's possible to fly around in level mode. Once the sticks is outside the 200 area it's in acroMode and can be flipped over. Release the stick and it will return to stable. Change the ACROTRAINER value to suite your flight styl...

Any chance of adding straight USB support? My Asus tablet has a usb port on the dock that I use with a serial converter, so it should be possible.

signal15

Got it. So if I blow away the EEPROM, I've gotta restore my save file, but then recalibrate gyros, acc, and mag. And then manually trim my acc again. Oh, and set my aux buttons.

It would be nice if there was a way to store calibrations and ACC trim.

signal15

Does it just save PID and AUX settings, or does it save things not exposed in the GUI (like mag/gyro calibration, and acc calibration/trim)? What about things that are not used? For example, some people were having problems with their copters yawing to one side when Mag mode was on, but then erasing...

signal15

Can you calibrate just by powering through usb? The ESCs are just looking for throttle endpoints right?

signal15

Make sure you follow the procedure for trimming the ACC mode also.

signal15

Any way you can add landscape view? I have a keyboard dock on my tablet, and it's weird to use it sideways.

Also, with tablets, you may be able to fit all of the data on one screen.

signal15

I always take my props off when doing calibration. Doing a search on google images for rc prop injury will make you have a new respect for these things. Helicopters are by far the worst though.

signal15

Keep in mind that your power wires and battery produce a magnetic field. Everything may look fine when you are powering the board through the USB cable, but when the battery is plugged in and drawing current, it may be flaking out your mag sensor. I was having problems with mine, but it turned out i...

signal15

Do you have mag turned on or off?

When I upgrade, is it going to erase all of my PID settings?

Also, will I have to retune my PIDs at all?

For those wondering, it does wipe everything. I put my old values in for pitch and roll, and left the rest at defaults, and it flies great.

signal15

If you look at the IMU code above, there are two scenarios coded into it. One with gyros only, and one with gyros and level mode. Taking into account level mode increased the time of one cycle to something like 5 times that of gyros only. Due to resource contraints, it might not be possible to do al...

How much and how big are laser interferometer gyros?

Oooh, there is a bunch of stuff on doing Kalman filters on the arduino:

https://www.google.com/search?aq=0&oq=a ... man+filter

signal15

So, would the Kalman filter be applied before sensor inputs were used at all? Or just before feeding them to the inertial nav code? If you're implementing it, I would think you might as well apply it so the resulting output is used everywhere. This would make vibration in general less of an issue th...

signal15

This is what you're talking about:

https://en.wikipedia.org/wiki/Inertial_ ... ion_system

The navy has used these for a long time because when traveling underwater (or under Arctic Ice) there is no GPS signal, and there are no stars to look at.

signal15

Too bad this firmware hasn't been ported to work on the Silabs F330 chips yet. Apparently it is possible, but no one has done it yet. Many of the ESCs coming out are switching to this chipset, but using the same model number they were when they used Atmel.

signal15

Will this be rolled into 2.1? Or is 2.1 frozen?

signal15

Sorry Patrik, To just fly around it's a bitch, but for doing flips it's amazing.... in a moment of desorientation, you don't need to find your level switch as before. just let go of the sticks, and voilla all sorted. I upped the 200 to 250, and it's not bad flying around. Technically, I could up it...

signal15

Too bad er9x doesn't work on the Devo radios with the touchscreen.

signal15

Over on RCG, someone asked the question if the following code would make more sense. I agree that it may:

Code: Select all

if (abs(rcCommand[ROLL]) >=200 || abs(rcCommand[PITCH]) >=200) acroTrainerMode=1;

signal15

Isn't the Derivative term of the PID loop supposed to adjust for predicted future change? I haven't looked at the code, but the D term is supposed to take care of this.

signal15

What a adrenalineKick!... My first flip ever! I tested the code and it works fine. A little warning.... The transfer betweem the modes is very sharp. When you pass the threshold with the sticks it will become Wild! If a lower threshold value than 200 it can be more soft. I will test it better tomor...

signal15

Ok, holy crap. I tried the code above. I set my RC Rate to 1.0 and my Pitch/Roll rate to 0.7. I got it up about 50 feet and tried some rolls, letting go of the stick right before it was level again. Works like a charm. Then I pulled the stick to the back right corner, and did two backwards pitch/rol...

signal15

I'm just about to test the code above. Does the Rate setting for pitch and roll get disabled in level mode? I didn't see it in the PID loop anywhere, unless it's returned from this: dynD8[axis]

If that's the case, then it DOES get disabled in Level mode.

signal15

You could also do something like that in your transmitter, rather then in the MultiWii. if your Tx has some decent firmware, that allows custom switches, it should not be so difficult. That's a good point. I have a DX6i right now, I'm not sure there's a way for me to program this into it. I have a ...

Awwww sweet.

This seems like it would be awesome feature for one of the next releases. I can certainly patch my own code, but it would be nice if this was already included. I think I saw something on the wishlist for 2.1 that was similar to this. Even better, it would be cool to be able to define the params in c...

Not sure what the CPPM signal actually looks like, I'm assuming it's some sort of tag that's sent within a frame from the satellite to the control board. This idea is 2 parts: - Modified code on the Turnigy 9x (er9x) - Modified code on MW The modified code on the 9x would provide for an LCD menu wit...

I want to start trying some acro stuff, but I don't want to have to flip on ACC if things go wonky. I want it to flip on by itself when I release the stick to center position. Can I leave ACC on, and still do acro stuff, or do I have to disable it? It seems to me that if you're doing greater than 75...

signal15

Is it possible with the DX6i to activate 4 modes in any combination? Above, it looks like you can switch between modes, but I want to be able to enable any combination of modes. For example: - Just ACC - ACC and level - ACC and mag - ACC and headfree - ACC, headfree, mag, and barometer Basically, I ...
