I've just released ArduPlane 2.32
This is a minor update with 2 changes:
The new MANUAL_LEVEL option is a boolean option. If set to zero (which is the default) then the existing behaviour of doing automatic accelerometer calibration on every boot is used.
If you set MANUAL_LEVEL to 1 then it won't calibrate the accelerometers on boot and will instead use the values from the last time it did a calibration. The idea is that you get a good level once, then set MANUAL_LEVEL to 1. You can then redo the level using the mission planner or another ground station, or by setting MANUAL_LEVEL to 0 and restarting.
The compass learning change is based on feedback from the last release where noise in the magnetometer caused the learning to be quite bad for some people. The automatic offset learning should now be robust to quite large amounts of magnetic noise.
update your mission planner and then in the firmware tab update your APM then look in the configuration tab MANUAL_LEVEL 0 change the 0 to 1
Thanks very muth Brad. Know i have it. I forgot to update also the mission Planer.
Hi all, I just did a first test flight this morning with Bixler and APM2/ArduPlane 2.32.
I experienced a strange thing... Everything was going smooth (stabilize, rtl) was A ok. But I lost control of the airplane and the Bixler circled slowly down to the ground and crash on tip of wing. When I was near the crash site, the ESC was beeping (throttle no signal) and all leds on APM was off... ???. I suspect a bad jumper on APM2 (I replaced it with another one today) and fixed the airframe. Fortunatly the crash was not to severe and I managed to repair the Bixler. Another thing I should mention is that the GPS lock was looking flaky (long time to get a fix)... I mounted the GoPro on Top of the APM chassis.
... probably a bad idea.
So... today, I moved the CAM in front of the Bixler chassis in order to not block the GPS antenna.
To be honest I'm a bit scared for the flight test #2.
...any idea what could have cause this?
Just an idea. Might helps;
Is your ESC big enough?
Can its bec handle all the servos, APM and everything else together?
If it can not, than it reboots, and your throttle setting gets messed up also in it.
Happened to me before.
Thanks for your reply Gabor, it is exactly the case... I reproduced the problem on the workbench.
The ESC effectively heats up pretty bad and reboot after 1-2 minutes at 3/4 of throttle.
I will put this GWS ESC in the garbage and never buy again.
I just placed an order on DIYDrones Canada for a new ESC.... hopefully it will do the tricks.
At full throttle, current setup is using 23amps.
If you got a telemetry look then we could look for causes in that. For example, it logs the board voltage, allowing us to tell if your BEC was keeping up OK.
If you did get a tlog then please post it.
thanks Tridge, the issue is not related to Arduplane. but a cheap ESC. (see below)
I had a similar issue twice and after doing some tests I've discovered that my ESC BEC was not handling the current consumption.
I've added a separate BEC and never crashed again.
Tip for everybody. Add a separate BEC to your system and do not use the ESC to power APM and servos (mainly if you use digital servos).
You should consider adding a protection lens :
It is really light and might save your camera
Has the Arduplane 2.32 been well flight tested ?
Most tested code we've ever released. Many hours in the air, on sims and through automated code verification. And at this point there are so many thousands of APM boards in use that users quickly identify any edge cases that didn't show up in developer testing.
