MultiWii

Compilation relies on having the correct board selected. For example you can't compile code that writes to eeprom if you have a board selected that doesn't have eeprom, you get errors similar to the ones you are describing.

P

This probably means you need to increase MINTHROTTLE. Bare in mind it's one of the * values that needs a eeprom reset to change (Note 1 at the top of config.h)

P

The only time I've seen these kind of errors is if I've got the wrong board selected in the the Tools | Board menu. Might be worth a look?
If not maybe try a fresh install of the Arduino IDE

I'm trying to get this working too. So far I ended up changing the battery code in MultiWii.ino to get it working. I'm not really all that familiar with this type of coding so forgive me if it's an awful hack; it does seem to work though. #if defined(VBAT) static uint8_t vbatTimer = 0; static uint8_...

However, this is not mentioned att all, neither in the link provided above, nor in hobbyking's description of the board The hobbyking board isn't the same I think, the DataFlash only got added to the Crius in v2 and the hobbyking board looks to be a copy of a v1. The RCtimer page says "Onboard...

I think it's more that the AIO Pro 2 has an Atmel 45DB161E 16Mbit DataFlash on it.
MegaPirateNG has a library to access it, I imagine though it's too niche to spend time trying to integrate it.

P

I don't think sonar is implemented yet to that extent (at least they seem to say as much here viewtopic.php?f=6&t=3364 )

I struggled with this. On v2.2 at least, any "spare" serial port just seems to sit there waiting for an MSP connection. So long as you have your baud rates set correctly you can have devices on each port at the same time without any additional configuration.

P

they are enabled by default Just knowing that allowed me to work it out thank you. Looks like I had my serial port numbers confused and had the wrong baud rate configured, but kept ignoring it because I didn't think it was the one I was connected to. So instead of checking the simple stuff I set ab...

(e.g) I have OSD on Serial 1, GPS on Serial 2, and "other" on Serial 3. Sorry, to jump in. I'm currently trying to do just that myself with my Crius AIOP v2 with no success so far. Is there some multiwii (I'm on 2.2) config that needs to be set or are all serials active on a mega by defau...

Seems whenever I post to a forum I end up feeling foolish thanks for pointing that out Hamburger, I knew I must have missed something. At least I know it's by design even though it seems very counter intuitive to me.I'm guessing long term these will need MSP messages defining for them and inclusion ...

I'm not sure if this is working as designed but I've found tweaking 2.2 very confusing until I realised a few of the values in config.h that appear to be static are actually written and read from eeprom. This looks to have come about due to the multiple configuration profiles feature, even when that...

I reeealy wanted to ask that but was too scared of an angry bicopter builder berating me for asking silly questions :p

I think the first step would be to work out if it's software or hardware.
What shield / sensors are you using?
Does the roll react correctly other than being upside down?

For me the bluetooth adapter issue is easily repeatable, I videoed it here for anyone interested: m The first time I plug the BT in while it's running it kills the Arduino and needs a reset, then the next time you hear the back two motors go full throttle for a couple of seconds before all motors di...

I've had this on my hex and finally worked out in my case it was down to the bluetooth module I had plugged into the serial port on my pro mini. With the copter on the ground and the props off I'd wiggle the bluetooth module and get the back two props on full power for a few seconds, then the pro mi...

If we're looking at the back of the copter in the video it's certainly the motor rather than the prop. I point it out as on my first go I thought naively that the firmware somehow told the motor which way to turn, as randomly 5 out of 6 went the right way by luck and the symptoms were similar to you...

It's tough to tell, but on this video http://www.youtube.com/watch?v=hWDgrO6Zc4U it looks like the bottom right motor is turning the wrong way. Could just be the video though.

P

When you say the motors on the right have a higher value do you see the value in the GUI or from observation?
In the GUI, is roll at 1500 when your transmitter stick is centered?
It could also be your ESCs not being synced up for throttle range maybe, might be worth setting it again.

P

It feels like I've got to the bottom of the twitching issue. Over paranoia about vibration all things When I first fixed the sensors after redesigning them the velcro must have been very stuck together, but I removed the sensors after the crash and must have loosened the velcro so now it doesn't hol...

Good points. I've recalibrated my transmitter and changed the code to up the interleaving delay which has pushed cycle time up to 8K. After doing that the slight pitch and roll offset in the screenie above has gone so I'm hoping its a good sign. I'll give it a go tomorrow and report back. Thanks for...

I'll have a play with that interleaving delay, I'd missed that thanks. I've been thinking vibration issues too, but I'm on my 4th go at a sensor mount with varying levels of dampening and some times it flys fine. Other times it's insane to try and keep up in the air and there have been very little d...

I believe I've correctly set up the ESC's and the transmitter. I did the routine with the ESCs to set the range and changed the throw in my DX6i to get all the sticks from 1000-2000 as best I can. WMP timing I've set at 100khz and I've calibrated the ACC many times but for the moment I'm in acro mod...

Hi there, I've built myself a hex; MW1.9, Pro Mini, no shield, original WMP+NCK, 3S 2200mah, 18A Hobbywing ESCs, CF2822 motors, 8x4.5 Props, MM6 type frame I can get it in the air, but it's incredibly twitchy and no amount of PID fiddling seems to tame it. The twitching seems generally limited to ro...
