There are various algorithms for digital control including Fuzzy Logic and ANN, note that ANN isn't the actual controller. It learns in time for the best constants to feed into PID control algorithm, hence we can start off with the default PID constants. pid+ann.PNG Adrian A. Hopgood "Intellige...

Hello All, I wonder, could Adaptive PID be implemented into MultiWii project instead of the current Conventional PID values. This would involve to incorporate Artificial Intelligence (some sort of a Neural Network) into digital control to make PID values adaptive in the closed loop. This question wo...

Dear All, I have flushed MultiWiiV1_8 and noticed on the Configuration GUI that when I have barometer enabled, I increase/decrease throttle, BARO is flickering by turning on/off. I've been wondering is it a bug or it is suppose to be since I haven't came across such behavior in previous releases! I ...

Hello, Has anybody done or came across an open source code to create a Glass Cockpit View in Java OpenGL? I know I should code it myself however if there is something out there, why to reinvent the wheel I am looking to control my quad via PC referencing the forum thread: http://www.multiwii.com/for...

Thanks guys for the answers! So I guess I might do some coding to change one of the unused digital channels on Arduino Pro Mini as an input for ch6, or else maybe purchase a different receiver in the future.

Hello, I've HK 6ch TX/RX and Pro Mini. How do I connect AUX2 from the RX ch6, since only mode (AUX1 ch5 on the receiver) is currently connected to PIN7? From the firmware code it says that AUX2 is also on PIN7 but not used! Do I have to modify the code in the current development version of MultiWii?...

Thanks for the post!

Hello, I'm building my quad and struggling to put it in the air. Yesterday I measured frequencies with regards to the image in FAQ http://static.rcgroups.net/forums/attachments/2/6/7/7/0/3/a3627948-90-freq.jpg?d=1291043990 . First I'm gonna outline my components: Motors: Hacker Style Brushless Outru...

Thank you Alex for your fast response, we'll do that:)

Dear All, I have 4ch transmitter and 6ch receiver. For my tricopter, I have connected MODE connection from the 6ch receiver to the Arduino Pro Mini pin 7. However I have no chance to switch a stable mode on or off, since I’ve only 4ch tx. Question: is the stable mode with such setup enabled through ...

Dear All, With the reference to http://wbb.multiwii.com/download/file.php?id=31&mode=view Has anybody tried to connect IMU Digital Combo Board - 6 Degrees of Freedom ITG3200/ADXL345 from Sparkfun http://www.sparkfun.com/products/10121 through LLC to Arduino Pro Mini? Unfortunately I couldn't get...

Thanks Alex:) I'll try that!

The only answer to my question I found is to reduce vibration to absolute minimum, however I am wondering, is it possible to do it programatically via firmware?

Dear All, Does anybody have an idea why tricopter tail servo is shaking during and after calibration via GUI, gyroscope/accelerometer calibration and accelerometer trim. While tricopter is positioned horizontally, tail servo turns the tail chaotically to both directions. I use Multiwii firmware vers...
