OK Mooch and Maj,,sorry we had a freak snow storm roll threw here and raise hell with flying and doing anything else. Hobby King I know this is not relevent to parts but it is what we do after flying in the shop,,,,he he
When I can't figure out why my copter (or some other robotic or bean counter stuff....) zigs when it's suppose to zag ... music helps clear the nerve synapses that are not working correctly and more often than not, the "answer" just pops out of nowhere while the music is on .. why I cannot explain ... Anywhoo ... the weather here is not nice too ... windy, cold and raining ...
On some screens the config.h tab and others won't fit, on the very right edge of all the tabs there will be a hard to see arrow pointing downwards, click that and you should see a list of files that hopefully has config.h in it. If not the MultiWii download page is at hxxps://code.google****/p/multiwii/downloads/list just replace xx with tt.
no dice in that drop down menu their is no cofig.h but their is one in the documents this is what arduino tell me when i load the scrip
* Welcome to MultiWii.
* If you see this message, chances are you are using the Arduino IDE. That is ok.
* To get the MultiWii program configured for your copter, you must switch to the tab named 'config.h'.
* Maybe that tab is not visible in the list at the top, then you must use the drop down list at the right
* to access that tab. In that tab you must enable your baord or sensors and optionally various features.
* For more info go to www.link *
* Have fun, and do not forget MultiWii is made possible and brought to you under the GPL License.
i have tried every 2.3 code i could find does anyone have a ready made code that all i half to do is change the config.h settings i am using a f550 hex
DJ ... try it again ... config.h is on the drop down list very near the bottom ... which is very easy to miss. It's there as I just looked a few minutes ago while configuring a Hex. Another possibility is that your screen resolution may not be set to view the entire Arduino window ... try scrolling around....
Quick question for someone in the know! I have fitted this to my quad, wired up and loaded in the latest sketch, I fire up the GUI and no matter what I plug into the throttle channel on the flight controller it will not recognise any input.
Hence it will not work, any ideas?
Wayne .. need more info ... what a) MWC version did you upload ... b) What GUI are you using? c) the posted doc for pinouts is not "correct" for the Rx side, outer is ground, center is power and inner is signal. c) make sure your Rx is bound to the Tx/radio ... yes it happens. d) are you 100% sure your are connected to the FC board? Can you see sensor activity? e) did you calibrate your Accel in the GUI? If you can please post a YouTube video .. best diagnostic tool ever ...
Thanks Majik, all good points, I am running MWC 2.2, all options for an X copter, setup for Simonk esc's Multiwii WinGUI 2.2, all of which is working fine.
I do have the wiring correct, I got my magnifying glass out to make sure I had the right pinouts, it's labelled but in very small print, signal wire inboard, negative to the outside.
I did make sure I was bound to the receiver, I can see movement on all other channels, AUX 1 and 2, roll, ail, rudder all work fine, all motion is displayed on the graph, it's just not showing any response to throttle on the live rc data section, all other controls are moving and displaying correctly. I have taken the throttle lead off the FC and sat it on another channel and it works, the PPM signal is there, the flight controller just won't do anything with it. I suspect the board has a dead input. I can do a video if you really need one but it will be just as I've told you, there's not so much to see.
I really appreciate you replying, I'm not new to programming boards or flight controllers but the multiwii is new to me, I hear they are good and am sure some are but not so impressed at this stage :)
I assume any other channel connected to the Throttle input does not work either ... that eliminates bad cables, incorrect inputs and any obvious items. However, sometimes the MWC sketch gets corrupted and something fails to work properly. Try loading a new MWC 2.2 sketch but this time clear the EEPROM first. Go to Arduino > Files > Examples > EEPROM . eeprom_clear ... compile and upload. This blanks out the board's memory prior to loading a new sketch. Hopefully it works for you. If it still fails to work contact CS for a replacement .... they should be able to help.
Yeah I tried multiple leads, different receivers, channel changes, clearing the eprom and about 3 different itterations of sketches, all great advice and very much appreciated, seems I have a dud then!
Thanks got your advice, you've obviously spent some time with these things.
I'll have to wait another month now by the time this is replaced :-) who is CS by the way?
Maj have you seen any reason to incorporate the HC-SR04 ultrasonic sensor for an add on for altitude control?,,,or is this money not well spent? Has anyone tried it that you know of and what results did they have with low level accuracy? I'm thinking along the lines of low level sports video's while filming jet boats coming at me, passing by me,,,then speeding away upstream. Since the barometer over any level is sketchy at best (depending on the foam) then over water (only way to get the good stuff) would defiantly need a little more reliability or,,,,,splash,,,,lol
Enough said. Hey Mooch was up late last night ripping a few,,,,see which one to throw your way of my fiddle at work,,,,wanted to show you a little ditty I wrote,,,,and then of course rip one thats noisy (a regular hillbilly hoe down),,,,,lol I'll throw one of them up here. It is pouring here,,,and said to last for three days,,,so looks like I will be working on my boat today and tomorrow,,,no flying,,,***mer,,,, Stay safe, and thanks for the come back Mooch,,,see ya
Newey ... I have a sonar sensor but it is used for different FC .. Mooch is right, the baro takes care of heights above 3 M and the sonar below 3M .. but who flies at 3M? Interesting to see but has no real need ... except for auto landing to prevent the "bounce" .... Can't wait to hear your ditty .... I have some in my head and have used them for background in my earlier vids ....
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
