Right you are. It looks like 3.15 is out now. I haven't tried it, but I'm sure it will work about the same as 3.14. I have to go try it myself now...

This link says 3.14, but it's really 3.15.

Well done. We can certainly see that the UAVP is not happy with the receive channels. Channel 1-5 must be within 100 and 1FF, or no green light. Channels 6 and 7 don't matter. I assume you have no compass?

First, make sure your radio is in Airplane mode, not helicopter. There should be no mixing at all turned on. Set channels 3 and 4 to "reversed", and leave the rest on "normal".

Verify that you have connected K12 connectors as follows:
pin-1 to ground on any servo channel of the receiver
pin-2 to channel 1 signal pin on the receiver
pin-3 to channel 3 signal pin on the receiver
pin-4 to channel 5 signal pin on the receiver
pin-5 to channel 7 signal pin on the receiver (this is optional)
pin-6 to +5V on any servo channel of the receiver.

Finally, make sure you have "throttle channel 3" on UAVPSet.

FWIW, I just ran the new test software myself, and here's a capture. I do have a compass, and the barometric pressure sensor, so it will be a bit different from yours. I am only using 5 channels, and you see that 6 and 7 "failed", but it still says the receiver channels are "OK".

Good luck,
Rusty

Did you get a green LED with the AR6000?

The UAVP was made to work with a common PPM type radio, using individual channels, rather than requiring all the channels in one PPM composite pulse stream. This is the only quadrocopter I know of that allows this. All others require you to either use their receiver, or modify one.

The PPM composite is a string of pulses, one for each channel. The width of each pulse determines the servo position for that channel. The pulses follow one right after another, then start over. In order to save inputs, the UAVP folks realized that if you know where the odd channels start and stop, the time in between must be the width of the even channel pulses. This allows them to determine the even channels, even though they were never physically connected. Pretty slick.

Bottom line, the UAVP sees all the channels, so don't try to help it by getting too creative

Channel 1 is roll, 2 is pitch/nick (never figured out where "nick" comes from), 3 is throttle, 4 is yaw, 5 simply switches between two pre-set flight parameter files. It's very important that there be no mixing.

Advanced modes like PCM, and whatever CCPM is, can throw it off, and the whole 2.4 GHz line has really thrown a monkey wrench into it. There's no rule that says radios must use the old PPM timing of channel outputs, so there are some receivers that simply won't work. I still believe your Futaba will, though I'd never choose that over 2.4 GHz.

There are certainly receivers that just won't work, but I can't say if that's one of them.

Usually, this is a low battery warning. In UAVPSet, what's your low battery limit set to? The battery alarm won't stop the UAVP from flying BTW, but if you have the beeper hooked up correctly (not backwards), you won't want to be close to it. Man is that thing LOUD!

What do you mean by "uC" ?

When you're connecting via the odd channels, your choice is 5 or 7 channels. Even though the AR6000 is 6 channels, you'll only get 5.

As for "mixing everything around", I'm afraid you're trying to make this harder than it is. You don't mix anything. You don't have to move, or reassign any channel. You want the most basic airplane mode you can get on your radio.

If you hook up channels 1,3, and 5, the UAVP will see 1,2,3,4, and 5, just exactly as if you hooked all of them up. If you add channel 7's connection, the UAVP will see ch 6 and 7 also. FWIW, 6 and 7 aren't used unless you want to tilt or roll your camera manually. Even with 5 channels, the UAVP will gyro stabilize the camera in tilt and roll directions.

It's too early to get worried. I'm sure we can get this working

SO I just do move the THR stick, and the green LED turns off, then NO LED's are on. If I move it back to off position, Green LED turns back on.

Now that's just odd... Do you have any close up photos showing how this is all connected?

Do you have access to an oscilloscope?
