MultiWii

TL;DR : This is about hardware in the loop simulation : having an multiwii flight controller running in a flight simulator .

Baseflight and Multiwii are supported along with FlightGear simulator .

There is a new msp_set_attitude message in the private range of the protocol.

You will find some more detailed information in the multiwii-mavlink-gc wiki. feel free to comment .

Here is a short maiden flight in horizon mode and some switch to accro mode .

very nice!
need to play with it.

Liking it. Nice work

the latest git stuff does not compile.
neither windows nor linux...

what does it says ?

if this is about __STRICT_ANSI__and -pedantic .. i wont change that

MAVLINK_SRC_CFLAGS := -lm

ähh!?
you mean linker flags, isn't it

you should not use this function in an mcu.
it is a pain what it uses in terms of resources.

edit:
before i forget it - write a cmake file.
make files are shit.

Great work on the groundcontrol mate,thanks for all the help in getting me up to pace with the workings
@brm the windows version should compile now ,i could put up the exe if needed
Ill soon edit this with a video of my quads

i removed lib math , please tries again

what mcu are you using ?


ps : make is everywhere .. cmake is not everywhere

oh, all mcu's which are decent.
8 bit is braindamaged to a certain extend.
but event with 32 bits it can happen to run out of cpu cycles.
and this happens often

love it to have a pelican in my hands...

and yes. it compiles

@treym
hmm,
je vriend uit amersfoort benut zo een flexbot.
is dat ding goed?

i dont knwo anything about that flexbot , but as far as it look , it dont look attractive to me .

I'm not using this for the flexbot yet, that needs a Bluetooth LE to serial bridge first.

flexbot sounds really dumb.
3D printing 100 frames was OK idea, proceeding with that plan after getting 10K+ orders was beyond retarded.
Using obsolete hardware on new product in 2014, even more so.

old 8bit 328p can now run in simulation


36h long fly away .....

Can someone please share a runnable version for windows?
I can't get it to compile.

Hi,

we have an issue with MWII that we cant reproduce in lab, so I'm curious if it could be simulated with HIL simulation?

As posted here http://www.multiwii.com/forum/viewtopic.php?f=8&t=364&start=450#p59144
flying an airplane acrobatic on a roll with several turns the plane doesn't stop but keeps on rolling
So I wanted to ask kindly if anyone having a working HIL could try that once which would be of great benefit?

THANKS!

i did not see anything weird yet , i am not using the most suitable planes for acro .. will do extensive testing later
