MultiWii MicroWii ATmega32U4 Flight Controller USB/BARO/ACC/MAG

MultiWii MicroWii ATmega32U4 Flight Controller USB/BARO/ACC/MAG
MultiWii MicroWii ATmega32U4 Flight Controller USB/BARO/ACC/MAG

The MicroWii is a complete multi-rotor flight controller. It is based on the ATmega32U4, which is the processor of the Arduino Leonardo. The MicroWii incorporates an MPU-6050 chip, which is a combined gyro and accelerometer plus a precise MS5611 barometer and HMC5883L magnetometer.

This is the ultimate solution for powerful flight performance with your multi-rotor project. The possibilities are endless with the MicroWii, only limited by your imagination!

Features:
• USB on chip (no FTDI or UART needed)
• Free serial port (it's possible to use a DSM2 satellite together with the GUI)
• 6 receiver inputs
• 6 high resolution (11-bit) PWM outputs
• Supports all configs up to OKTO with cam-stab support
• 2.5kB RAM
• ATmega32U4 based with Leonardo Bootloader
• 10DOF sensor array
• MPU-6050 (GYRO/ACC)
• HMC-5883L (MAG)
• MS5611-01BA03 (BARO)
• Bluetooth/GPS connector (on bottom; only GPS or DSM2 satellite can be used at one time since the 32U4 only has one UART)

Specs:
Main chip: ATmega32U4
CPU speed: 16MHz
Flash size: 32kB (3.3kB are taken by the Bootloader)
Input: 6 x high-res RX inputs (2 AUX channels)
Output: 6~8 motor outputs (motor 1-6 are 11-bit PWM)
Dimension: 50x50x16mm
Weight: 14g

Hi Guys, Anyone had any experience with this controller? I have been trying to set mine up for the last few days. I have calibrated my RC TX - Turningy 9 channel I have calibrated my ESC's - Afro 30 Amp SimonK's I have calibrated my Acc on level surface. I can see all controls moving correctly on GUI and are centered at 1500. I have balanced my props I have plugged motors up according to the GUI Picture.. using predator 650 frame. When i goto take off it starts to lift off and then starts to pitch backs wards rather quickly :( lit its going to flip... When i hold it and move craft around it appears to fight any movements I make.... using standard PIDs supplied with this board..... Im stuck... please any advice or suggestions would be great.. PS - I have posted this here to see if anyone specifically that purchased it has any advice.. Thanks in advance!

Hi there as part of my year 12 school project I have undertaken the task of building a quadcoter for my CAD (computer aided design) course. I have managed to do rather well until now, where I've got to the stage where I can get it into the air but after 1 sec the throttle seems to cut before reengaging, this ends up giving the effect of bunny hopping even thought the throttle is half way. ANY IDEAS? I believe that I might be something to do with the barometer, and have tried the "getto" fix of cotton wool which didn't seem to help. PLEASE HELP BTW I uploaded my quadcopter to the photos

Hi Scott. It doesn't sound like a baro problem to me. With multiwii it's not recommended to fly around with baro on like you can with a Naza or APM. Make sure your baro is turned off and try again. It almost sounds to me like your flight battery is flat. If the voltage of the pack is dipping a lot when you go to take off you'll hit the lower BEC limit and all of your speedies will turn off. It could be other things but try that first.

I can assure you that the battery is not flat when I try this, and I bought a brand new battery for this exact reason. I am interested however, how would I turn of the barometer off, is it in the "config.h"

No it's in the GUI. You need to set one of your aux channels for baro if you want to use it. You also need to set the other functions like auto level etc. You will most likely need to adjust the gain settings.

HI, I could not turn the engine, I suggested in the manual but not config.h league. use the Turnigy 9X 9ch and the lever to the left or down diretia not start the engine. through the tip "#define ESC_CALIB_CANNOT_FLY // uncomment to activate" could turn the motors Another doubt I have food as the flight controller 5 volts ?? that pin?

Pushed one config.h I got on google and my controller does not work properly. What would be the correct config.h to the plate? please give me the download

Unfortunately, this board does not work too. If you set "# define A32U4ALLPINS" so you otherwise transform function on pins 'input'. Also in version 2.1 MultiWii not work "common setting ESC". The problem is also with the USB driver in W7 (the problem is already described on the Internet). Tile not responsible Flyduino board layout components and thus not working.

I uncommented #define FREEIMUv043 and #define A32U4ALLPINS. (the first define identifies the FC and makes sure the new sensors are all made active, and the second one clobbers all the receiver pin-outs, if you want to use all pins) The receiver inputs change from what the labels say on the board to the followings: Throttle remains Throttle, Roll becomes Yaw, Pitch becomes Aux1, Yaw becomes Pitch and Aux1 becomes Roll. I don't use Aux2, but intuitively it should remain unchanged. I am using it on a scratch built Tri-Copter and it flies very well, using the stock PIDs. The sensors on this board are really good. I am very happy with this board. Make sure you install USB driver for Leonardo, in order to be able to connect to this board on Windows.

It is a good value. But the minimalistic manual is wrong. either you do not uncomment //#define a32u4allpins or you uncomment it and connect the corresponding channels from the receiver to the Flight Control in the right order (you can watch it in the MultiWii-Config Utility). When connecting the board to PC, try to connect it to an USB 2.0 Port, not USB 3.0. That can save you a lot of trouble. My Quadrocopter is flying pretty well. Check Video 61745350 on vimeo.

Uncomment #define A32U4ALLPINS #define FREEIMUv043 and #define RCAUX2PIND17 for AUX2 It works! sequence pins from thr: thr, yaw, aux1, pitch, roll, aux2

Ho montato questa Multiwii sul x230 mini quadcopter, finalmente sono riuscito a fare funzionare tutto. Ho usato il software multiwii 2.2, per fare andare la scheda e poter usare tutti i canali bisogna attivare questi valori nel file config.h #define FREEIMUv043 // same as FREEIMUv04 with final MPU6050 (with the right ACC scale) #define FORCE_MAG_ORIENTATION(X, Y, Z) {magADC[ROLL] = X; magADC[PITCH] = Y; magADC[YAW] = Z;} #define A32U4ALLPINS #define RCAUX2PIND17 facendo questo la pinnatura dell'input della rx sarà modificata risultera la seguente partendo dal THR: Thr - Yaw (Coda) - Aux1 - Pitch (Elevatore) - Roll (Alettoni) - Aux2 Cosa molto importante è anche mettere la scheda nel verso giusto, il senso della freccia e la lettera N serigrafata sulla scheda indicano il verso di montaggio, in pratica la scheda andrà montata col connettore USB rivolto nella parte posteriore del quad, e cmq non di spigolo come altri fight controller. Prossimamente montero anche un GPS, ma adesso devo prima affinare i settari, anche se con quelli di default il quad vola gia abbastanza bene.
