Rabbit Flight Controller

Lfhm_Tools_20120306_English.zip

1.  new GPS functions: indication of the number of satellites being locked, go home and position lock
2.  Improvement on baro altitude hold above 2m.. improvement on auto-landing which was too fast .. improvement on the Ultrasonic altitude hold on long glass grounding
3.  Ultrasonic altitude lock changed back from 1.5m to 2.0 meters
4.  improvements on PTZ stabilisation
5.  Correct the control in fixed wing and delta wing mode
6.  include servo reverse and receiver channel reverse
7.  add servo signal update frequency options
8.  correct altitude change when applying rudder
9.  direction lock changed from reference being made while un-Arm to being made when switching on lock
10.  add more beeping advice tones while calibrating the compass
11.  correct the case after auto landing, the fc can only be un-arm after switching off auto landing

Brief Decription:

This Flight controller adopts 32 Digits ARM CPU and latest sensor with Independent research and development software, ensuring stable,safe and reliable flight in a simple setting suface.The board contains high precision tri-axis gyroscope and tri-axis accelerometer with compact structure and size.With stable and balance function without any aditional board.Multi-function: can be connect with ultrasonic, barometer,tri-axis magnetic sensor,GPS etc.,thus to realize height lock,direction lock, and self- lift-and- down function.8 Channel remote input and 8 Channel motor/servo output.Support aerial photography and PTZ Self-Balance.The output mode can be setted by user.With USB interface, Upgrades PC and adjusts parameters without Expansion Board.With PC upgrade tools,it can improve program and upgrades online according to majority user's requirements .

Features:
- 32 digits ARM CPU,50 MHZ frequency
- Support 140g mini quadcopter.
- With high precision tri-axis gyroscope and tri-axis accelerometer for self-stability and self-balance.
- 8 CH receiving ports,can set auxiliary switch channels or PTZ control channel except 4 main joystick channels.
- 8-CH 16 digits high precision PWM output channels,can set 50Hz～500Hz analog/didital servo or non- standard ESC singal.
-Supports mix-control:GIMBAL,BI,TRI,QUADP,QUADX,Y4,Y6,HEX6,HEX6X ,OCTOX8,OCTOFLATP,OCTOFLATX,FLYING_WING,FIEXD WIND mode and so on. can be added other modes according to users requirement.
- With USB interface and PC upgrade tools,convienent for users to set parameter,and download the newest program.
- 8 LED singal to indicate various mode, convinient to set parameters anytime even for a tiny adjustment. Can connect color LED strip, makes magnificant and unique night flight.
- Supports 4S battery Voltage test, ensure to test each battery.
- Provide alarm port,facilitate users to set low voltage alarm, the alarm sound will be quicker and quicker with the voltage is lower and lower.
- With ultrasonic port, makes precision height lock within 2 meters (the best effect with flat ground), switch to barometer height lock out of 2 meters.
- With equipment self-detection function, make sure safty flight . with sound and light signal during the self-detection.
- With high precision tri-axis magnetic sensor,barometer and GPS port etc.,facilitate users to add functions such as automatic lift and landing and return.(just buy additional board and upgrade the software online)
- With Independent research and development software, can improve or add new functions as users requirement.
