Andrew Tridgell 1e0a2fb0be MAVLink: don't waste 100 bytes of bandwidth sending 1 byte of information
the GPS_STATUS message is a massive waste of bandwidth, but it is the
only message that tells us the number of visible satellites. So only
send it if that information changes.

This makes MAVLink work better at low baud rates

Andrew Tridgell e9773ea09c APM: use set_blocking_writes(false) when we have done ground start 2012-03-30 17:46:20 +11:00
Andrew Tridgell 0985327331 ACM: use set_blocking_writes(false) when we arm motors 2012-03-30 17:46:20 +11:00
Andrew Tridgell 08b66e18b7 FastSerial: added set_blocking_writes() interface
this allows us to put a serial port into non-blocking mode, so that
writes that don't fit in the transmit buffer are dropped. This will be
used in flight to prevent stray printf() calls from causing large time
delays in the code

Andrew Tridgell 36e741b078 MAVLink: raise the serial transmit buffer size to 256 bytes
the 128 byte serial transmit buffer was causing significant problems
with queueing of mavlink messages. With 256 bytes we can fit a lot
more messages out in each pass of the code, which makes telemetry more
efficient

As we discussed on the dev call, we now have enough free ram for this
to be worthwhile

Andrew Tridgell c221c91f87 autotest: use the automatic declination code in autotest 2012-03-30 14:25:27 +11:00
Andrew Tridgell c2ff66c9cd examples: fixed build of some examples with new AP_Declination code 2012-03-30 14:25:27 +11:00
Andrew Tridgell 5dbd2a2b60 APM: enable AP_Declination by default 2012-03-30 14:25:27 +11:00
Andrew Tridgell 58f539ca35 ACM: removed FORCE_AUTOMATIC_DECLINATION_UPDATE
we now have the EEPROM option COMPASS_AUTODEC instead
2012-03-30 14:25:27 +11:00
Andrew Tridgell 825340d53d Compass: added COMPASS_AUTODEC option
when this is 1 (which is the default), we will get the declination
automatically via the AP_Declination library

when it is 0 we will use the value configured by the user

Andrew Tridgell a98a092a59 AP_Declination: enabled auto declination by default in APM 2012-03-30 14:25:27 +11:00
Andrew Tridgell e4e052ff91 AP_Declination: save some more memory by putting the declination keys in progmem
there was a comment saying this was too slow, but it actually costs
about 30 usec extra, which is trivial given the full auto declination
call costs 680 usec and its only called once per boot

Andrew Tridgell 01c4cde14f AP_Declination: fixed build under SITL 2012-03-30 14:25:27 +11:00
Adam M Rivera 9c414e9573 AP_Declination_test: Updated test with better print messages. 2012-03-30 14:25:26 +11:00
Adam M Rivera cff189e911 AP_Declination: Update LUT based on the changes that I made in the LUT generation code. This LUT is the final version that has no truncation. 2012-03-30 14:25:26 +11:00
Adam M Rivera 0727955fe3 ArduCopter: Changed implementation of configuration value for automatic declination. There is now a FORCE_AUTOMATIC_DECLINATION_UPDATE that when enabled will update the declination on every GPS 3D fix regardless of whether or not the user saved a value to the EEPROM. By default the declination will only be set by the automatic declination routine if the user has not saved a declination to the EEPROM. 2012-03-30 14:25:06 +11:00
Adam M Rivera 380b9ece44 AP_Declination: Updated comments to reflect new LUT size. 2012-03-30 14:25:06 +11:00
Adam M Rivera c04e074c89 AP_Declination: Removed trailing zero deltas as they have no impact on the final value and only take up extra bytes. 2012-03-30 14:21:58 +11:00
Adam M Rivera 662f11f801 AP_Declination: Updated compressed lookup value table. Located 9 more failure points due to truncation on the packed LUT. 2012-03-30 14:21:58 +11:00
Adam M Rivera 0178906389 AP_Declination: Found 7 of the 22 failure points and fixed them. The issue with those 7 was the way I originally packed the value array. The last delta values on some rows were getting truncated. The new number of failures is down to 15 - WIP. 2012-03-30 14:21:58 +11:00
Adam M Rivera 08259bb2de AP_Declination: Updated test to run in 5 degree increments. Changed to only print failures and also print total pass vs total fail. 2012-03-30 14:21:58 +11:00
Adam M Rivera 64c236800c AP_Declination: Moved check for y index of zero to after the y index is properly transformed. 2012-03-30 14:21:58 +11:00
Adam M Rivera e99d26cfa3 AP_Declination: The exception signs unpacking logic was incorrect. I was shifting a 1 value left y%8 which would have needed a the signs to be packed right to left. My packed signs byte was packed left to right (left most being the 0 position) so I needed to reverse the shifting. 2012-03-30 14:21:58 +11:00
Adam M Rivera d9c9e0e608 AP_Declination: In order for the bitwise & operation to work, negative signs need to be represented by 1s instead of 0s. Changed so that negative signs are represented by a 1 in the packed signs array. Updated lookup logic to reflect this change. 2012-03-30 14:21:58 +11:00
Adam M Rivera 8b1c383f97 AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly. 2012-03-30 14:21:57 +11:00
Adam M Rivera c0813f8d62 AP_Declination: Changed test to run in increments of 10 degrees. 1 was too granular. 2012-03-30 14:21:57 +11:00
Adam M Rivera 289d7a2784 AP_Declination: Added original array to test sketch. Added loop to validate new compressed array against original in 1 degree steps. 2012-03-30 14:21:57 +11:00
Adam M Rivera 63ce400f77 AP_Declination: Moved rows with large spikes in delta to their own unsigned exception rows. The signs are in a separate packed array. 2012-03-30 14:21:57 +11:00
Adam M Rivera 782c1aaaa3 AP_Declination: Implemented Delta Encoding and Run-Length Encoding. Added method to traverse the compressed array and return the lookup value based on the same lat_index/lon_index that was used before. 2012-03-30 14:21:57 +11:00
Adam M Rivera 9888a4730f AP_Declination: Changed PROGMEM read function to pgm_read_word_far to support the int16_t datatype. 2012-03-30 14:21:57 +11:00
Adam M Rivera d883bdf75e AP_Declination: Changed datatype to int16_t to support the -90 <-> 90 latitude range. 2012-03-30 14:21:57 +11:00
Adam M Rivera 719636d00c AP_Declination: Reduced the size of the lookup table to support -75 <-> 70 latitude range. This allows the datatype to remain int8_t. 2012-03-30 14:21:57 +11:00

Andrew Tridgell 03800ec5f4 APM: Added MANUAL_LEVEL option
when MANUAL_LEVEL is set to 1, we don't do accelerometer levelling at
startup, and instead used the values saved in the EEPROM. This makes
it easier to do levelling on the bench, or once for a series of
flights for the day

Andrew Tridgell 071f89df2e AHRS: fixed error_yaw reporting with 2 MAVLink connections
when a user first connects with USB, and later switches to the
telemetry port without restarting we were getting zero for error_yaw
in the logs, as AHRS.get_error_yaw() was being called twice.

This ensures we give the last value after the counter is reset
