Another suggestion:

An ACTION to command FLIGHT_TERMINATION.

MAVlink Packets like this could be used for those ones participating UVA Outback Challenge and are changing APM code for it ;-). Or to command the same IO pin the current APM code allows.

Omar

Hello!

I'm a new member to this community and I recently acquire an APM 2.0 Purple and my goal is to use the APM 2.0 and the APM Planner to visualize in flight data.

I need help, besides all the information displayed in the HUD display it is possible to add to the gauges tab or to the HUD display the information regarding Acceleration in the 3 axis (G-load) and pressure and temperature from the MS5611 Pressure Sensor built in the APM 2.0?

Best regards

André Marques

Andre: If you want a customizeable GCS compatible with APM, check out QGroundcontrol

Hi All, Another sugestion:

If APM is set to use throthel Fail safe, if it leaves out RC range, it engages RTL. If RC signal restores, APM is automaticaly set to the current mode from the switch mode. I forgot myself this behaviour 2 times.

Could I suggest to APM Planner to present some alert in case there are at least one mission point far away from home when the throtle fail safe condition is turned on?

regards,

Omar

RE: 7. Grid feature, this is excellent, looking forward to trying that out! Nice one chaps, keep up the good work!

Hello

I have a Ardupilot Telemtry Log (.tlog) and I want to extract data from the gyro and accel to a (.txt) file, is there any way of automatically doing this using APM Planner?

Best Regards

use the tlog to txt or csv function.
flight data > telemetry log > tlog > kml

Hi Michael,

Is there a way to load more than 175 waypoints to the APM 1.X?
I see in the code that the space is calculades based on Memory addresses and space for fence.

I tried with a mission having 207 WPs. It completes the load but when read from APM to planner it stops in the 175 waypoint number and didn't present any point in the Mission Planner screen (missing the read WPs).
Also the Combobox for the "Set Waypoint" buttons doesn't allows to set the point 207 or other major than WP 128. I see too that the Distance>WP, when distance have 5 digits, the WP number is not presented entirelly.

regards,
Omar

@omar - it's not even an issue with MP. Even if MP allows you to load more than 187, there isn't enough EEPROM space on the Amtel chip to support it. The first 1k is used for parameters, and the rest of the 4k space is entirely dedicated to waypoints. Even with the massively truncated Mavlink waypoint format, there isn't enough space for more than about 187 entries in the script. 

 

However, I've been toying with different approaches to addressing this issue as a tangent to another team's request for additional mavlink features, see this video:

 

and also this discussion: http://diydrones.com/forum/topics/change-loiter-radius-from-waypoin...

You would NOT want to use the stdio9-more-mavlink code as it is, it would create more problems, because it reduces the eeprom space to 104 entries. But because I find this unacceptable, I have been toying with different ways to reclaim the space, or even make room for tens of thousands of entries. If you need it, I could maybe work up a branch of code to support something like that. I suspect that MP would allow you to transmit the larger missions as-is, and if not, with only a very simple change. However, I am fairly certain you'd be running a custom ArduPlane code, as I'm not comfortable (yet) with submitting these kind of changes to the devs for consideration because they are features that almost no one else needs, but they would impact everyone, even if only slightly. 

Cheers.

That's too cool Mike!  BTW, where or how do I get the APM & the X-plane settings for the Bixler?

 

Thanks,

Dan

Dan,

If you mean the X-plane virtual model I put together, the parameters I use very successfully are at the bottom of the blog entry at http://diydrones.com/profiles/blogs/hilstar17-public-release called/linked here  HiLStar-June2012.param

If you mean for a real bixler, not a virtual X-Plane model, there is a file called "bixler.param" at http://code.google.com/p/ardupilot-mega/downloads/list

Cheers,

-Mike

Hi Mike, I meant the virtual model for now but thank you for sending links for both.  This is very helpful.

Muchas gracias,

Dan
