exaxtly as happul3 wrote.

It was easy enough to do an integration over time and assign the result to the debug[] variable. Then at the end of the flight one could see the accumulated error. Repeat for numerous flights to learn and see it will likely resemble noise only -:(

I need a change to MSProtocol in order to support 6S HV lipos. Todays HV lipo cells support 4.35V, soon to come 4.55V. For 6S, this equals 27.3V. At the moment, we use uint8_t for storage, which is no longer sufficient. Affected structs are typedef struct { uint8_t vbat; // battery voltage in 0.1V s...

Hamburger

the standard MultiWii gui (your screenshot) only polls values every so often - you would miss most values in a series.
Probably must write your own polling code and somehow check if you are fast enough to get all values of the series.

Hamburger

before we get excited - where does this come from, please? Under what licence?

Hamburger

not yet

Hamburger

those are defined for each mcu separately and differently.
You must create a new section for your mcu. Best to follow what gets done for the mega mcu in def.h

Hamburger

you could use my.private.settings. look it up in the wiki

Hamburger

hard to tell without the specs.
Anyway better to get a digole brand display.

Hamburger

okay, probably good catch.
Noted for further maintenance work.

Hamburger

I see.
In this case I concur with ezio - voltage under load is what kills batteries, so why worry about noload.equivalent?
Not convinced.

Hamburger

arduino mini pro is 328p?
In general, do not move around pin assignments unless you know your way around.
328p with MWii would allow for more than 3motors+1servo outputs, I think.
Try and find how additional gimbal servos are supported.

Hamburger

look for the lcd_* functions in lcd.h
Some push output over the serial interface just like printf()

Hamburger

about nominal voltage
can be set in config.h.
is used as reference point for bar graphs with lcd.telemetry.
is used for voltage drop compensation under load (if enabled in config.h)

Hamburger

The following would be true for original MWii ( for 32bit derivatives I do not know):
MWii does know current voltage and allows to define 3 alarm levels already. (also the nominal voltage aka resting voltage when charged can be defined)
I do not understand what it is you had to implement

Hamburger

no, not yet.

Hamburger

with 328p you only have one serial - also used for usb. So you cannot have both at the same time. While it was possible to run GPS on 328p in the past, it is not recommended - and I have no idea if/how it fits in the small memory. My advice is to get your GPS gadget working with a MEGA board first (...

Hamburger

when sensor as 6050 are positioned 'hanging on the wall' then you will get very different ranges in the raw data from the sensor already. Your best bet is to re-tune your PIDs.

Hamburger

shy would that be a problem? Simply do not force a new mag orientation in the config and be done?

Hamburger

Bluetooth would mean a wireless version of serial communication with your MWii fc.
Lookup the MSP documentation for what commands the fc does understand and how to create valid commands.

Hamburger

Hi Hamburger, Yes, we want to add support for our barometers into Multiwii. As I know, Bosch BMP085 and MSI MS5611 are both used by Multiwii platform. I have no idea how to contact the key person of Multiwii about accepting new barometers. Please give me a hand if you can help. Hey Maxwell, we have...

Hamburger

you want to see us adding support for your baro into MWii?

yes

Hamburger

at the moment we are waiting for Alex to setup the new official repository. so no changes atm. due to technocal read.only limitations. in general, it is a combo of tech and social you should create patches, post those here and contact one of the registered devs who is technically close to your patch...

Hamburger

If we did it right it wont matter.
I am quite sure we did.

Hamburger

that is for the free mem value @ runtime. (either EOSBANDI code or the other implementation already present in the code from arduino forums)

Hamburger

Below 100bytes free is a direct route to lockup.
With 200bytes free you should be good.
Pure e perience. 0 science.

Hamburger

you could enable the 'display free memory' feature maybe and check how much free memory your MWii reports once it is running. With all my incidents during testing where I enforced or somehow encountered 'low memory' condition it always caused complete lockup of the main loop. Not your symptoms, so m...

Hamburger

yes, but
at one point we decided to have all features off by default. So users are forced to go through config.h in any case. As Alex put it "MWii is not a product".
With some TX/RX combos it is easier to begin with when failsafe is off.

Hamburger

You will receive pm soon.

Hamburger

There is an older long thread titled wishlist with a collection of - wishes.
You understand this is an open source project driven by volunteers. So no guarantees your wishes get honored and implemented. But chances are ... chances.

Hamburger

In MWii you can override the default buzzer pin to whaever free pin you have.
Enable buzzer and in gui you can assign buzzer.on to an aux channel.

I do not know your board or alienwii. The 32u4 is capable of driving a buzzer.

Hamburger

In the works.

Hamburger

please check your voltage dividers. If sum of both resistors is too high (whatever that value may be) then the arduino input seems to float and provide phantasy values for analogRead(). One symptom is if arduino value changes drastically once you attach a voltmeter in parallel to the arduino input.

Hamburger

hey, the vbat cells code does need some fixing. I will get to that during winter. You may also have experienced that infamous side effect of too fast consecutive analog reads influencing results. Best advice for the moment is: if it works, fine. Else either try and fix it for yourself or leave it fo...

?

Hamburger

probably best to use patrikE's airplane implementation - it has gps support specifically tailored to airplane purposes.
Can always be found in his branch over at the googlecode repository.

Hamburger

you could try and join every two sid-by-side motors+escs and their servos and drive these from the same fc outputs.

Hamburger

with a quad (unless completely different in size etc. from anything we have seen) one should not have to ever use
#define GYRO_SMOOTHING {20, 20, 3}

Either you should reduce vibrations from drivetrain etc. or do more pid adjustments.

Hamburger

Does the fc receive the msp data or is another serial device obfuscating that port?
How do you create the msp commands with correct checksum? It is binary data.

Hamburger

Did you callibrate the escs to your (default) throttle range?
The huge copter body works as a giant dampener against all movements of pit h roll and throttle change. If too extreme you might have to use beefier power system
If you are lucky then a high P value for roll and pitch should do the magic.

Hamburger

maybe you should put yaw on all 4 servos? then yaw-corrections and -inputs could maybe have less unwanted differences in vertical thrust components.

Hamburger

good to hear you made it! Congratulations.
For once I will be looking forward to seeing a demonstration flight video.

Hamburger

can you please explain what 'rocking wings'would be or provide a link to show what you have in mind?

Hamburger

dunno if I understand what you want to do. But you could always do things like

Code: Select all

motor[0] = rcCommand[THROTTLE];
servo[5] = (SERVODIR(5, 1) * rcCommand[YAW] + get_middle(5);

Maybe the flying.wing and helicopter mixing code will give you an idea what is possible?

Hamburger

Cool. What was the problem or misunderstanding?

Hamburger

Yes. Looking good as a starting point.

Next you must write your mixing code for 4motors plus 4 servos in output.cpp.
It is rather straight forward.

Also you must make your quad.tilt become another option and value for multicopter.type variable.
You are on the right track now.

Hamburger

As starting point you need a type with 4 motors and 4 servos. This is possible but not setup yet.
From there it is only mixing stuff mostly.

Hamburger

Both the old google wiki and the official wiki look ok now. Seems to have been fixed by now.

Hamburger

Sounds convincing to me. It is now on my ever growing list
