rmackay9 c034e38cbd ArduCopter HIL: changed calls to setHIL to send in time as a uint32_t (it was a float) 2012-06-26 22:50:17 +09:00

Andrew Tridgell ae9883a8e2 GPS: fixed auto-config of UBlox setup with no UBX messages
if a UBlox is configured for NMEA only, with no UBX messages at all
then it would never trigger the GPS_AUTO detection. This adds a UBX
config message to the init strings that enables the NAV_SOL message
2012-06-15 15:53:27 +10:00
Andrew Tridgell b7e807cd58 FastSerial: added tx_pending() method
this allows the caller to wait for the tx buffer to drain

Andrew Tridgell f4718cafad GPS: re-open the serial port with a 256 byte serial receive buffer
this ensures all GPS parsers have a 256 byte buffer available
2012-06-08 16:42:03 +10:00
Andrew Tridgell ddebf7b443 GPS: fixed the UBLOX parser to handle unknown messages
the parser was broken in several ways:

 1) when it received an unknown message it didn't update the ck_a and ck_b fields, so it
    thought the message had a bad checksum, which meant it got out of protocol sync

 2) the read() method would return false if the last message from the GPS was of an unknown type. 
    So we relied on the last msg always being one that we understand and want

 3) the parser considered any valid UBLOX message to be 'new data', whereas we only actually get 
    a new fix when we get box a new position and velned message

 4) the total message size per update is more than 128 bytes, but the serial port was opened 
    with only a 128 byte buffer, so we got corruption regularly

Andrew Tridgell c2fb8a7a98 DataFlash: use ChipErase() instead of PageErase() on all pages
This makes the DataFlash erase much faster (about 6 seconds instead of
about 60 seconds).

We need to test and ensure the behaviour is equivalent apart from the
speed

Andrew Tridgell 8f27297896 DCM: fixed a bug when using GPS for yaw correction
When using GPS for yaw correction we need to apply the x and y omegaI
corrections from the _omega_I_sum in the period before we get to the
minimum ground speed for GPS yaw correction. Otherwise we get a large
sudden omega_I change on takeoff.

Andrew Tridgell fef4134702 MAVLink: removed the cpp part of the library

can't set cpp defines
2012-04-24 22:24:58 +10:00

mechanisms available via waypoints
2012-04-24 10:57:43 +10:00
Andrew Tridgell 6d837891b0 DCM: buffer omega_I changes over 10 seconds
this buffers up _omega_I changes in _omega_I_sum over a period of 10
seconds, applying the slope limit only when _omega_I_sum is
transferred to _omega_I.

The result is a huge improvement in the ability of _omega_I to track
gyro drift over the long term.
2012-04-23 12:13:25 +10:00
Andrew Tridgell 398a608b83 DCM: drop the 'drop z' method
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:

  http://diydrones.com/xn/detail/705844:Comment:834373

Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.
