Pat Hickey 83326a9d62 APM_RC_APM2: Add support for CH_10 and CH_11
* CH_10 is on APM2 pin A10 (based on A1..A8 convention)
* CH_11 is on APM2 pin A11

* Only the code in enable_out, disable_out, and OutputCh needed to change.

* CH_10 and CH_11 always have an output period of 20ms (50Hz).

Doug Weibel e22a83eec0 Add a CLI setup action to reset the magnetometer offsets
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI.  Useful if you somehow get bad offsets or if you change magnetometer.  If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values.  I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.

Andrew Tridgell 897d9a1c0b baro: fixed an integer overflow issue at high altitudes
the averaging array was using 16 bit numbers, but we are storing
numbers with 19 significant bits. That caused overflow at high
altitude, and some very interesting altitude graphs!

Thanks to Michael Oborne for spotting this in a log

Andrew Tridgell 15d446bde2 DCM: prevent a segmentation fault when compass is not enabled
when compass is disabled _compass is NULL
2012-01-13 15:48:07 +11:00
Doug Weibel 9846822748 Bug fix for compass.
This is a fix for an interesting bug when a DCM matrix reset was added to the ground start.  This bug only showed up if (A) a ground start were performed after an air start or due to use of the "Calibrate Gryo" action, (B) if the current orientation were sufficiently different from 0/0/0, and (C.) if the particular magnetometer had sufficiently large offsets.  Why did resetting the DCM matrix to 0/0/0 pitch/roll/yaw at ground start cause a bug?  The magnetometer offset nulling determines the proper offsets for the magnetometer by comparing the observed change in the magnetic field vector with the expected change due to rotation as calculated from the rotation in the DCM matrix.  This comparison is made at 10Hz, and then filtered with a weight based on the amount of rotation to estimate the offsets. Normally it would take considerable time at normal in-flight rotation rates for the offset estimate to converge. 

If a DCM matrix reset occurs when the offset nulling algorithm is up and running, the algorithm sees the DCM reset as a instantaneous rotation, however the magnetic field vector did not change at all.  Under certain conditions the algorithm would interpret this as indicating that the offset(s) should be very large.  Since the "rotation" could also have been large the filter weighting would be large and it was possible for a large erroneous estimate of the offset(s) to be made based on this single (bad) data point.

To fix this bug methods were added to the compass object to start and stop the offset nulling algorithm.  Further, when the algorithm is started, it is set up to get fresh samples.  The DCM matrix reset method now calls these new methods to stop the offset nulling before resetting the matrix, and resume after the matrix has been reset.

Randy Mackay bbe6dea980 OptFlow - initial support for APM2 (there are still problems) including adding ability to set Chip Select pin.
Other unrelated changes are:
a) fixed typo in 'esitmate_velocity' to 'estimate_velocity'.
b) moved init_compass from system.pde to sensors.pde which seemed consistent with other sensors.

this moves out all the high level logic from ArduPlane/ArduCopter to

disable logging on APM2 if a dataflash card is not inserted
