Hi,

I can't see register link either.
Only login option.
latest new member is from 1:st juli -17.

Maybe Alex locked for new registration to avoid the spam we had at that time?.

PatrikE

A tip can be to search for "brushed" in config.h

PatrikE

Hi I'm not sure what you want to do but this will not be a flyable thing as it is!... Just 4 separately controlled motors. rcCommand[x] have a range of -500 to 500 and center is zero so you have to add MIDRC to get it in correct range. motor[0] = rcCommand[ROLL] + MIDRC; rcData[x] is the "Raw&q...

It's not active by default In config.h
Just enable and it will work in 2.4.

Looks like another project we done here..

I have code for it if you want..

The model is Quadwing and the transaction is made by AUX2 if i remember correct

The two components is enough for building a flight controller. It's easier to use a commercial FC though. I started at the time hacking MWii controller was the only way to go. Most of my fails during flying have been those Fc's failing, Soldered cables vibrating off and similar issues. A ready FC al...

PatrikE

A 328 will be good enough until you start adding GPS etc.
Then it will be short of memory.
But you can easily config the setup and test to compile in Arduino ide to get a Idé of sketch size.

PatrikE

Maybe not plug n play but it's something to start with.

PatrikE

Should be possible to use the Dual Copter Mix.

PatrikE

MultiWii is still my first choice in my planes.

PatrikE

If you Short the GND and RST the board will reboot.

PatrikE

You need to calibrate the esc's.
Default setting in MWii is that motors spin at idle when it's ARMED.

Uncomment to change it.
#define MOTORSTOP

PatrikE

I guess a good start would be a Openlog. ex m And add a combined GPS/Mag. ex m You can probably find cheaper on Ebay You might have to solder some directly on the processor legs to get it to work though!. You need I2C for the Mag and a input for PWM/PPM on the Openlog. Most of the code you need is a...

Eclipse is open source and free.
Keil have a free version that have a limit size on compiler.
But there's always ways to unlock for the handy man..

PatrikE

You can use Eclipse to code.
It's not the easiest to setup though!

Easiest is to use Kiel light version.(32kb limit)
http://www2.keil.com/mdk5/install
And use gcc to compile as a free option.

Baseflight works nicely with Kiel or Eclipse.
Cleanflight with Eclipse

PatrikE

You can do like that. But the FC will never know it's in failsafe and continue to circle at home until the battery runs flat. A better option is to trim down Throttle to absolute minimum and save it as failsafe. leave all other channels neutral. You can probably trim it to around 990µs or lower. Adj...

PatrikE

No.
Multiwii is not compatible with NAZE32 Boards.

Better to get a Mwiii fc.

PatrikE

Sorry.
I don't have any experience of using Softserial.
But GPS should be OK to run at 38500 since only 5Hz is used.
I have been running a NMEA at 36k on MWii FixedWing.

Or you could just connect a push button as a jumper easy accessable.

PatrikE

You need to insert your code before the PID regulator.
https://github.com/multiwii/multiwii-fi ... .cpp#L1467

The paramerers you should manipulate is.
rcCommand[PITCH] += pitch_advoidance_Command
rcCommand[ROLL] += roll_advoidance_Command
rcCommand[THROTTLE] += hrottle_advoidance_Command
rcCommand[YAW] += yaw_advoidance_Command

PatrikE

There's servo Tab in the MWiiGui to.
Then you can connect it to PC normally.

PatrikE

Upload the code as usually with dynabalance activate temporarily in config.h Open Motors Tab in Gui. It's not visible in normal mode. Enable the motor you want to test in the Gui and run the motor from gui. Do i have to mention the risk of running motors with props on the bench? Comment dynabalance ...

PatrikE

In config.h

Code: Select all

#define MINTHROTTLE 1150 // Idle speed when armed without #define MOTOR_STOP 
#define MINCOMMAND  1000 // value sent when motors is stopped/DisArmed

If your FC is sending 1000 and the motors is still running i guess your esc's need calibration.

Hi,

There was a project for a couple of years ago on google code .
You can find it cloned on several places on Github

RX_RSSI is reading one of the incoming RC-channels as RSSI value.
You can add your RSSI to ex channel 8 with the range (1000 - 2000) like a normal servo PWM signal.

You can also read PWM with analog filtering like in your link.
The analog will remap voltage in to RSSI value instead.

PatrikE

you can find the stable releases here.
https://code.google.com/archive/p/multiwii/

they should all work on a 328.
2.4 can be tight to fit with too many sensors though.
but without Gps and baro it should work.

Actually you need to remove
static const
and leave

Code: Select all

float _filter = 7.9577e-3; // Set to  "1 / ( 2 * PI * f_cut )";

Because newer Arduino IDE does not support it like older did.
Or downgrade the Arduino IDE.

PatrikE

Try to remove "const"

PatrikE

I also ave a Mongoose so i will look at it and apply a fix.
Haven't thought much about it even though it't my most used FC.

It's perfect format for small airplanes.

You can send via MSP.
There's a separate msp for Rc.
Must be sent with about 20Hz update.

PatrikE

Just as a fun note on this old thread...
After almost 4 years this exists as a product!..
Let's agree we are a bit innovative!
Not as cool as a Humvee Quad anyway!...

http://www.gearbest.com/rc-quadcopters/ ... ign=FB1511

PatrikE

Not by default.
You need to custom build a mixer to handle it.

It's not complicated but takes some knowledge about the code.

If you can present some info i can probably help you to setup the mixer.

PatrikE

Start with clearing Eeprom.
There can can be some old scrap left..

PatrikE

To edit and upload MWii to a Flight Controller you need to open the source code in the Arduino IDE.
https://www.arduino.cc/en/Main/Software
File/open then open the mwii file int the project.

PatrikE

WinGui and EZ gui have log functions that can save the telemetry data during the flight.
A Bluetooth or another wireless Telemetry link is needed though.

PatrikE

It's just a change to integer in the code instead of Float!.
100% equals 1.0

No i have not flown iNav just made some bench tests of it.
I don't like the behaviour of the PID's it use though!..
It behaves more like a copter!
Will maybe test it when summer temperatures return.

PatrikE

Together with EZ-gui It should work without changes in MWII.

PatrikE

Load the latest dev and not the stable...
The servos is broken in the stable version!..

PatrikE

In Baseflight there's no autonomous flight.
You can look at the iNAV branch of cleanflight.

500 is 50 degrees.

Change it to 50 and it should limit the Tilt angle to 5 degrees.

PatrikE

Hi, Do you mean the Max allowed angle for PITCH/ROLL in Angle Mode? It's set static to 50 degrees in Multiwii.cpp and limits both Axis. if (f.ANGLE_MODE || f.HORIZON_MODE) { // axis relying on ACC // 50 degrees max inclination errorAngle = constrain(rc + GPS_angle[axis], -500,+500 ) - att.angle[axis...

PatrikE

No It will force Horizon if not Angle is set by AUX.

PatrikE

Nothing will save you after a brownout! The Gyros can not calibrate during the reboot since it's moving... But to force HorizonMode... In MultiWii.cpp Row 1085 is a blank row. Insert rcOptions[BOXHORIZON] = true; That should lock the controller in Horizon Mode Should look like this. for(i=0;i<CHECKB...

No you can control entirely with MSP_SET_RAW_RC . Rc gets overridden by MSP_SET_RAW_RC if the channel value is >0. In fact you can run RC in parallel with msp. Msp will act as a Dual command master. ex. handle the flight with RC and AUX with msp. Send msp channels as zero if you want RC to control t...

PatrikE

I have played around a little before to make a GroundStation/Variometer.
Have a MSP Rc transmitter built in to it.
It's a Arduino project but you might get some Idés from it.

PatrikE

Have not looked any closer at your code but...
You must send MSP_SET_RAW_RC repeatedly with a ~20hz timer.
