Thanks for the clairification. I am still confused over which selection to use in config.h with my Cloned Crius MultiWii AIO PRO VERSION 2. Should I use freeimuv4, AIO Pro ver 1, or what?

Heck I cant even verify the Mag chip through inspection.. the labeling is worn off, but it should be a HMC5883L. Any way to tell what components are on the board through software?

I have found that the RX, TX, rts and cts signals won't be damaged if miswired to each other. BUT you must be carefull with the 5 volt and 3.3 volt connections. In this case dont use 3.3 volts. The way I recomend is disconnecting all escs and other voltage sources from the board and use the 5 volt supplied by the USB connection to your PC to power the board. So in your case wire the vbus (5v) to the 5volt connection and ground to gnd. This will power the board. connect tx to tx and rx to rx . and plug in the usb port to the pc. You should hear the bong as the pc discovers the usb device.
Then fire up arduino 1.0.1 and open the Mutiliwii version you want to use. I have not had an issue with any version from 1.9 to the latest development veresion. once the script is in arduino go to the board and comm port setting and make sure that your using the correct comm and processor. Then open the config.h file and set it for the type of copter your want to run, and set the board to the crius se. Once the setup in config.h is set just, upload the sketch to the board. It takes a while, but you will see the progress bar at the bottom. this may be too much detail as there are several "how to"s on the Multiwii site.
Thanks for the response!

I've succesfully uploaded the firmware Multiwii 2.1 but with this adapter instead:



I had to install some drivers included in arduino IDE though... I think this adapter is quite new (doesn't use the FTDI usual chip) and it has issues with the serial port recognition.

Well, I'm now doing the connections to the ESC but I've seen written on the Crius Multiwii SE v1.0 that if you have Switched BECs you just HAVE TO CONNECT ONE ESC's V+, the others just need the signal wire and GND (the others with the red wire cut off), otherwise it would burn. Is this true?

And I have the HK BlueSeries 30 A ESC, it says here) that they are SBEC. Does that mean they are Switched BEC and that I must only connect one V+?

When I had them on Arduino Nano before they did well all connected, it seems strange to me that they could make any issue. Could you help me a little more? I promise then I'll stop asking

Thanks again.

Hi to all,

I have one of this FC and now I have a problem, it seems that the information about the ACC and MAG calibration disappears almost every time that I change to a recharged battery.

Is this happening to someone alse? Someone knows what may be the problem?

Regards,
Luis Sismeiro

I would bet that the sbec is indicating that they are switched rather than linear BECs, so I would advice using a straight pin to lift the tiny tab holding the pin with the red wire in the 3pin connector, on all but one of the ESC, then a piece of heatshrink tubing to isolate the red wire so it does not touch anything. That way you can put everything back if you need to.
Gordon2,
This is the Crius MultiWii AIO board thread. The Crius All in one Pro has its own thread in the forums. So if your looking for info on the PRO you might want to take a look there. http://www.rcgroups.com/forums/showthread.php?t=1677726 Also there appears to be a "Crius AIOP V2 "thread as well.
I have no experience with anything but the AIO SE board.

Hi,

I bought a Crius All in one pro v2 board from rctimer.com. I have uploaded the multiwii software. Everything is working corectly, but my pitch is reversed on my tx. I have an old tx without options to reverse channels. Is there a way to reverse the pitch channel in de software. Maybe in de config.h file? If someone can change this file for me that would be great.

Kind Regards,
Rienk

Thank you!

I'll then just connect one V+ and all the others without it.

I'll try to have it flying tomorrow.

I got it flying very smoothly!!

In GYRO mode it is very unstable and likely to crash, but if you take off in LEVEL mode it is perfect.

Thank you very much for your priceless help, you've saved me! This tuesday I do the demonstration of my project, and now I have pretty neat and cool videos to show!

Thanks!

multiwii guru`s i need advice

will this gps board work as a stand alone unit ?
or must i have the nav board?


looking to add this to a multiwii se

link to gps >>http://www.goodluckbuy.com/ublox-6m-...al-for-fc.html

the info

UBLOX-6M GPS Module with EEPROM Built in Antenna Support TTL IIC

- Ublox NEO-6M-0001 antenna integrated GPS module built-in ceramic antenna
- USART serial TTL or IIC communication;
- The module integrates a 3V button battery;
- The serial port baud rate default 9600,4800 and 38400 optional;
- Built In EEPROM can save some setting to avoid some setting when power on;
- Compatible with a variety of flight controller like MWC 2560 FC;
- Not need extra IIC to TTL signal convertor board,can be direct use on MWC SE with 328P FC;
- Module size: 44* 32*5mm
- Module weight:20gram

now it sounds like theres no need for convertor board it says .your thoughts?

has anyone tried this?

Nice module you find

It has a Atmega328 on board ... so you can install on it the GPS to I2C converter ... but ... it should have it already inside ....

So ... you can put it directly on the MultiWii

Still for 20$ I can get a GPS, and with little software hack I can get GPS on MultiWii without any additional cost

Yup, looks like it has I2C output, so you should be able to hook up straight to your multiwii.

I wish to buy a GPS board for my Crius SE but I don't know much about it.
Could you explain the difference between this board and the CN-06 ?

In order to connect a GPS to a multiwii, you need to have the GPS signal as I2C. The board in the previous post says it has an I2C output, this one doesn't.

So to use this one, you need another board to convert the signal to I2C, like one of these:
