NEWBIES GUIDE to setting up and using the CRIUS MWC MultiWii SE Board Software
By ATXHELI rev. 12/26/11
1. Download and unzip the required software: -Arduino Compiler and Board Flashing Environment: http://arduino.cc/en/Main/Software -use the 0023 IDE not the 1.0 version -Latest MultiWii Software including Configuration Program: http://multiwii.googlecode.com/files/MultiWii_1_9.zip 2. Attach the FTDI USB board to the MultiWii SE board and plug in USB cable to PC 3. New Hardware dialogs will appear and point to the \drivers\ftdi usb folder in the Arduino folder for the driver. Driver should install and new device be recognized. 4. Start the MultiWii Configuration program.
5. See these tutorial videos on YouTube for operating the program: http://www.youtube.com/watch?v=qT3MlyRvy9w He has several other videos on the Configuration program that might be of interest also on his YouTube channel.
Some items in the program that might not be obvious (taken from Multiwii.com site):
RC rate and RC expo
RC rate: defines the sensibility of the multicopter for PITCH and ROLL RC stick. If you feel your multi too reactive, decrease it. If you want to improve its responsiveness, increase this parameter. RC expo: defines a smoother zone at the center of PITC and ROLL RC stick. With this function, it’s possible to have both a good precision and a good amplitude. 0 = no expo 1 = full expo If you don’t understand really those parameters, I encourage you to read your TX documentation, as those functions are also generally suported by the TX. It’s better to support them directly in Multiwii because the resolution is better this way.
P and I Level
Defines the acc influence in stable mode only (this parameter has no effect if the stable mode is disable) If the multi is not stable once activated, reduce P.
PITCH/ROLL/YAW PID and rate (see tuning section later)
For a very stable multicopter with a solid attitude, the PID settings must be set high. But if you want to
