jasonshort 8f17f95cbc Moved motors to individual files.
updated motor setup test to be sequencial pulses of the motors in CW order.
Fixed Mission scripting logic
fixed Free yaw error in neutral throttle
fixed D term issue with Baro hold - was too high
incremented firmware revision, removed frame var
removed setup show from startup
removed unused EEPROM functions
fixed broken demo mission
fixed non working loiter with delay

***********************************
Commands below MAV_CMD_NAV_LAST are commands that have a end criteria, eg "reached waypoint" or "reached altitude"
***********************************
Command ID Name Parameter 1 Altitude Latitude Longitude
0x10 / 16 MAV_CMD_NAV_WAYPOINT delay (seconds) altitude lat lon
0x11 / 17 MAV_CMD_NAV_LOITER_UNLIM (forever) altitude lat lon
0x14 / 20 MAV_CMD_NAV_RETURN_TO_LAUNCH - - - -
0x15 / 21 MAV_CMD_NAV_LAND - - - -
0x16 / 22 MAV_CMD_NAV_TAKEOFF - altitude - -
0x19 / 22 MAV_CMD_NAV_LOITER_TIME - altitude - -
NOTE: for command 0x16 the value takeoff pitch specifies the minimum pitch for the case with airspeed sensor and the target pitch for the case without.
***********************************
May Commands - these commands are optional to finish
Command ID Name Parameter 1 Parameter 2 Parameter 3 Parameter 4
0x70 / 112 MAV_CMD_CONDITION_DELAY - - time (seconds) -
0x71 / 113 MAV_CMD_CONDITION_CHANGE_ALT rate (cm/sec) alt (finish) - -
Note: rate must be > 10 cm/sec due to integer math
// MAV_CMD_NAV_LAND_OPTIONS (NOT CURRENTLY IN MAVLINK PROTOCOL OR IMPLEMENTED IN APM)
0x72 / 114 MAV_CMD_CONDITION_DISTANCE - - distance (meters) -
0x71 / 115 MAV_CMD_CONDITION_YAW angle speed direction (-1,1) rel (1), abs (0)
***********************************
Unexecuted commands > MAV_CMD_NAV_LAST are dropped when ready for the next command < MAV_CMD_NAV_LAST so plan/queue commands accordingly!
For example if you had a string of CMD_MAV_CONDITION commands following a 0x10 command that had not finished when the waypoint was
reached, the unexecuted CMD_MAV_CONDITION and CMD_MAV_DO commands would be skipped and the next command < MAV_CMD_NAV_LAST would be loaded
***********************************
Now Commands - these commands are executed once until no more new now commands are available
Command ID Name Parameter 1 Parameter 2 Parameter 3 Parameter 4
0xB1 / 177 MAV_CMD_DO_JUMP index - repeat count -
Note: The repeat count must be greater than 1 for the command to execute. Use a repeat count of 1 if you intend a single use.
0XB2 / 178 MAV_CMD_DO_CHANGE_SPEED Speed type Speed (m/s) Throttle (Percent) -
(0=Airspeed, 1=Ground Speed) (-1 indicates no change)(-1 indicates no change)
0xB3 / 179 MAV_CMD_DO_SET_HOME Use current altitude lat lon
(1=use current location, 0=use specified location)
0xB4 / 180 MAV_CMD_DO_SET_PARAMETER Param number Param value (NOT CURRENTLY IMPLEMENTED IN APM)
0xB5 / 181 MAV_CMD_DO_SET_RELAY Relay number On/off (1/0) - -
0xB6 / 182 MAV_CMD_DO_REPEAT_RELAY Relay number Cycle count Cycle time (sec) -
Note: Max cycle time = 60 sec, A repeat relay or repeat servo command will cancel any current repeating event
0xB7 / 183 MAV_CMD_DO_SET_SERVO Servo number (5-8) On/off (1/0) - -
0xB6 / 184 MAV_CMD_DO_REPEAT_SERVO Servo number (5-8) Cycle count Cycle time (sec) -
Note: Max cycle time = 60 sec, A repeat relay or repeat servo command will cancel any current repeating event
// need to add command
0xB7 / 185 MAV_CMD_DO_SET_ROI Yaw_Mode altitude lat lon
