Andrew Tridgell 73faaddc1b AHRS: first successful version of Bills new drift correction system 
This makes 3 major changes:

 1) fixes the scaling of the yaw drift correction term to fix the time
 constant

 2) don't integrate the mag vector over multiple readings

 3) accumulate omega_I changes over 15 seconds before applying, to try
 to prevent omega_I picking up short term responses

Andrew Tridgell b32726e867 GPS: need pgmspace.h for _write_progstr_block() 2012-06-15 16:27:11 +10:00
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 04a71197f9 FastSerial: avoid buffer re-allocation on re-open if possible 
we commonly re-open serial ports a lot in the AUTO GPS driver
 2012-06-09 07:43:22 +10:00
Andrew Tridgell f347572fc2 SITL: map() is a C++ function, so needs to be in C++ part of the header

Andrew Tridgell 9adaacedcd GPS: added debug code to the main GPS class 2012-06-08 16:42:03 +10:00
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

 2012-06-02 16:13:23 +09:00
rmackay9 3246f2bad3 RC_Channel library: change all "int" types to "int16_t". 
Fixes SITL compile error due to type mismatch of set_pwm between .h and .cpp file (this only occurs because on the SITL, "int" is actually "int32_t"
 2012-06-02 14:20:58 +09:00

rmackay9 df3fb5c041 ArduCopter: fixed print_latlon bug in which it would print negative lat/lon numbers incorrectly (i.e. -1234567890 would be printed as -124.xxx). 2012-06-02 12:51:12 +09:00
Jason Short 477aa6e47a RC_Channel fix for throttle output. 
throttle was outputting incorrectly and allowing the user to max out the throttle leaving nothing for attitude control
