The new KK2 FC, info and Q&A in first post. Read it before asking a question.


NEW FIRMWARE:
FW V1.1 here. (Do not use, but read page for information about the FW.)
FW V1.2 here. (Do not use, but read page for information about the FW.)
FW V1.3 here. (Do not use, but read page for information about the FW.)
FW V1.4 here. (Do not use, but read page for information about the FW.)
FW V1.5 here. (Same as V1.4, but with added camera stabilization support. See video below.) (Do not use, but read page for information about the FW.)
FW V1.6 here

Do not use metal hardware to mount your KK2. It may short out the PCB tracks and break the KK2.


Hi all, I designed this one to be easy to use for the noobs, and still be better than the KK1.

The gadgets-freaks will not pitch a tent over this one, It is the same, tired old AVR-chip. (Sorry TC ) However, it runs on a 20MHz crystal, so output resolution and jitter is better than before.

Some improvements:

-No confusing potmeter directions.

-No gyro reversing needed since the FW is for a fixed HW setup.

-Self-leveling. It uses acc tilt-angle measurement. Later I will try to add a full AHRS algorithm like the big boys use since it is better. (less delay) Done.

-No PC necessary. All adjustments and multicopter type selecting is done with the LCD and buttons.

-The transmitter setup can be checked before first test. (channels and direction)

-low drift gyros.

-graded low-voltage-alarm, adjustable in 0.1V increments.

-motor numbering and propeller direction is visible on the LCD.

-Custom mixer.


It will become open source when the first update is available. But beware, it is still written in Evil Assembly!!

Videos:

The first 17 seconds is with the KK1, the rest of the video it is with the KK2: (Self-level is not used)

KK2 Self-level toss test (1 min 31 sec)

Hobbyking KK2 board setup for gain and auto level with flight video (11 min 30 sec)


Calibrate ESC's using the KK2 Board (0 min 50 sec)


Gimbal set up on the KK2 controller with firmware version 1.5 (8 min 1 sec)


Roll/pitch P-tuning:

Set the gains and limits to the following values:

Roll/Pitch P-gain: 30 (For a small 25cm size set to 20)
Roll/Pitch P-limit: 100
Roll/Pitch I-gain: 0
Roll/Pitch I-limit: 20

Yaw P-gain: 50
Yaw P-limit: 20
Yaw I-gain: 0
Yaw I-limit: 10

Now, Increase Roll/Pitch P-gain by 10 (5 or less for a small aircraft) at a time, and test your aircraft response by hovering and move the left stick in short and fast movements.

See this video:
PI tuning: Response test (1 min 45 sec)


As you increase the gain you will notice:

1: The aircraft reacts faster and feels more connected to the stick movement and wander less on its own.
2: The aircraft may oscillate for a short time. Usually a few oscillations, but may be more if gain is high. If it oscillates continually the gain is too high.
3: The aircraft may be harder to land, it bounces back when touching down.
4: The aircraft may climb.

When the aircraft has a good response and does not oscillate or climb when testing, P-gain is good.


Roll/pitch I-tuning:

1: Trim it level.
2: Fly fast forward and center the stick.

If it level itself, increase I-gain.
If it stays in attitude, I-gain is good.

Alternatively setting I gain to 50-100% of P-gain does the trick.


Yaw P-tuning

Increase Yaw P-gain by 10 (5 or less for a small aircraft) at a time, and test your aircraft response by hovering and move the Yaw control stick until it have

yawed about a quarter of a circle, and then center it.

As you increase the gain you will notice:

1: The aircraft start and stops faster.
2: The aircraft overshoots less.
2: The aircraft may start to climb or descend.

When the aircraft has a good response, has a minimum of overshoot and does not climb or descend, P-gain is good.

Alternatively, set it to 100% of Roll/Pitch P-gain


Yaw I-tuning

Increase Yaw I-gain by 10 (5 or less for a small aircraft) at a time, do the same test as above.

When the aircraft overshoots even less, I-gain is good.

Alternatively, set it to 100% of Yaw P-gain.

If you have a small and not dangerous aircraft, you can disturb it around the yaw-axis and see if it returns. increase if not.


It is generally good to keep the gain values in the low range. Excessive gain may introduce vibration and control issues.

Also look at this video:
Multicopter PI-tuning: How to recognize different settings. (7 min 52 sec)



Airplane use:

1: setup the TX as described in the manual.
2: Connect the motor ESC to the RX as ordinary.
3: Connect a BEC to output#8, to supply the servos. Leave output#1 unused.
4: Using the mixer editor, find and connect the servos to the other outputs.
5: If you need to reverse a function (aileron, elevator, rudder), negate all mixing values for that function on all servos that are used by that function.
6: If you need to reverse a servo, negate the mixing value for that function on the servo in question.
7: adjust the stick scaling to get the required stick response.
8: adjust the mixing values to change the throw.

I recommend setting the I gains to zero when testing.

Alternatively, you can wait for HappySundays OpenAero firmware: https://www.rcgroups.com/forums/show...1568554&pp=100






Q&A: (Some of the text is borrowed from other users posts in this thread.)

#1
Q: It lists "Singlecopter 1M 4S", does that mean it could be used on say a Trex450?
A: No, but it is possible to configure the mixer for a heli. I will get me a cheapo 450 and see how well it works as a flybarless controller!

#2
Q: Is it possible to write FW on this controller to use as standalone Camera gimbal like the multiwii?
A: Yes, I will write a camera gimbal FW for it.

#3
Q: How does the low voltage alarm work? I can not see any connections for input V?
A: The Battery voltage input is the unpopulated hole to the left of the yellow component. Connect a cable from battery+ to this hole. The ground return is through Output #1's ground wire. Go to "Misc. Settings", "Alarm 1/10 volts:" to set the threshold. It is in 1/10 volts, so 10.5V is entered as "105". The LVC is only active when battery voltage is below the limit. When it goes above, it stops. Also it beeps faster the lower the voltage is below the limit.

#4
Q: Does the aeroplane mode also include autolevelling? or is that only available for copters?
A: It is available for planes too, but that combination is not tested. I will do it when I get more KK2's

#5
Q: CPPM input mode?
A: I will try to add CPPM mode. Done.

#6
Q: If the gyro can work on 2000 deg/sec, why not make the 2000 deg/sec as the working output? Which solder jumper need to be mod?
A: The 440 deg/sec gives a higher resolution. The jumpers is on a horizontal line below the two black chips at the top. From left to right: X, Y and Z axis. The pads already connected with a trace is 440 deg/sec. Cut this trace and connect (solder a thin wire) the center pad to the opposite pad to get 2000 deg/sec. Be careful not to short out the trace that runs in between the pads.

#7
Q: Why is Autolevel so slow?
A: The autolevel is based only on the ACC. It takes some time before the ACC registers tilt due to the horizontal acceleration of the craft when tilting. It needs some speed to get air resistance and a force on the ACC. Therefore the autolevel works best on draggy crafts. Later I will try to implement a AHRS algorithm, which uses both ACC and gyros to get a immediate tilt angle. Done.

#8
Q: What are the "limit" values in "PI Editor"?
A: About the "limit" values. They set the maximum of the available motor power to be used for correction. 100 is 100%. The "I limit" value is also known as "anti wind-up" in PID theory.
The limits is most important on the yaw axis. The prevent a large yaw correction from saturating the motors (giving full or no throttle), causing no control of the roll/pitch axis.
The default values permit 30% ("P Limit" 20 + "I limit" 10) of the motor power to be used to yaw correction, making 70% available for the roll/pitch axis, the most important ones.
You can increase "Yaw P Limit" for faster Yaw response. Note that Yaw response is also limited by the craft itself.
You can increase "Roll/Pitch/Yaw I Limit" for increased heading-hold "memory", that is how far it can deviate and still return to original attitude. Too large memory can cause problems if you have a "blow out" on one of the axis, tries to correct it with opposite control input and then when the blow-out conditions disappear, the craft will try to return to an unknown attitude.
Unless you know what you are doing, leave the limit values as default. Default values has no impact on The PI tuning process.
Also leave the self-level "I gain" and "I limit" at zero. The I part of the self-level algorithm does not work well, this will be fixed later. (Accelerometers is too slow)

#9
Q: Could you explain in detail how does the Height Dampening and Limit works?
A: "Height Dampening" in "Misc. settings" uses the Z accelerometer to dampen vertical movements caused by wind or tilting the craft. "Height D. Limit" Limits how much power available for dampening. Try 30 for the "Height Dampening" and 10 (10%) for "Height D. Limit".

#10
Q: Why does my Peizo buzzer keep making a beeping noise no matter what values I put on the "Alarm 1/10" voltage settings?
A: You must connect the battery voltage input to the battery. See question 3.

#11
Q: Can I use the KK2 with a cheap HK 4 ch radio?
A: That will be fine but if you want to turn on/off the auto level function you will need to do that at the LCD where as a 5th channel will enable you to do it from your transmitter.

#12
Q: I accidentally adjusted the contrast such that I cannot read the screen now.
Does anyone know how to do a reset to default contrast?
A: Turn the KK2 off and on again.
push button 4
push button 3 (four times )
push button 4
push button 3
push button 4
push button 1
push button 3 (36 times)
push button 4

#13
Q: In Tricopter configuration the LCD motor layout suggests that all the motors rotate clockwise. Is that correct?
A: On a Tri any combination of CW and CCW can be used, but the best is to have one of CW or CCW and the other two in the other direction.

#14
Q: How to reverse the yaw gyro for a tricopter?
A: Go to the "Mixer Editor" and change the channel (number to the upper right) to 4 where the yaw servo is connected. Then change the "rudder" mix value to -100.

#15
Q: Why that nut job of a ESC calibration sequence?
A: I know that some of you will try to calibrate the ESC with the propellers on, so by requiring to hold down buttons while calibrating, you will probably let go of the buttons and cause the motors to stop when the propellers start to slice through your arms. Also this makes it impossible to leave the ESC calibration on permanently. Why two buttons? In case some buttons get stuck, it will not enter ESC calibration mode accidentally. I see some defeats this by using clothes pins to press the buttons, but I recommend getting help from a friend. Of course, if you do remove the props, use the clothes pins!

#16
Q:
A:

Known bugs:
1: Arming LED stays on when entering the menu in "arming always on" mode.
2: LCD is sometimes blank on power up. Press menu to get the text to appear.
3: Bug in the flying wing mixing table. The offset on output#2 and 3 is zero, but should be around 50.

To do list:
1: Improve the Self-leveling.
2: Add configurable low pass filter for the servo outputs, to avoid excessive shaking and premature servo failure when using low-end servos.
3: Write a better tuning guide.

OK kapteinkuk, I realise you will open source it eventually but can you release the circuit to save me the effort reversing it? Pretty please?
What about the LCD? Can you point to any datasheets about driving it?
Any help is much appreciated.

Hello!
I am planning to enter the multi-rotor world, so I have ordered one of these, I hope I will be able to successfully make a tri-copter and a quad copter, I wonder which one is easier to maneuver for newbies.
Thank you for the buddy code, I apreciate all your hard work, and I hope more good things will com to this little board like magneto and barometers and gps hold and stuff

This is great! The "stick scaling" will make this great for those without expensive computer radios! Multicopters are getting so easy to get into!

And a ?

What are the flight characteristics with the autolevel? Do you still have control when it is on, or does it take control like an autopilot and level the multi until you turn it off?

If you have two then you may be able to use one for gimbal control if you set it to airplane mode. I would imagine you could also use the custom mixer to allow gimbal control, you may even be able to integrate gimbal control into any multi configuration up to 6 motors (8 total outputs).

Hi, kapteinkuk! Good to see that it has a 20MHz crystal and an ESC calibration mode! I'd probably want to add CPPM input mode so that we can just buy a simple receiver and only connect the one signal wire. It needs reordering support for some radios, but it's not that difficult otherwise.

Are the lines drawn between the motors not quite perfect in the picture, or is that just bad image scaling?

This one is from my account and hasn't been used yet. Remember, you have to be logged in first before you click on the link. It drops the price to $18.54 US.

Cheers!
the buddy codes did not work ...
and they have now limited it to 1 unit PER SALE !!!
that mean if u want 2 units u will have to make 2 orders
more shipping revenue for them
great ... no working buddy codes & 1 unit per sale

Sorry about that. Somebody must have already used it. I checked it to make sure it was working before I posted it. It appears to be dead now.

It lists "Singlecopter 1M 4S", does that mean it could be used on say a Trex450?

The gadgets-freaks will not pitch a tent over this one, It is the same, tired old AVR-chip. (Sorry TC ) However, it runs on a 20MHz crystal, so output resolution and jitter is better than before.

Some improvements:

-No confusing potmeter directions.

-No gyro reversing needed since the FW is for a fixed HW setup.

-Self-leveling. It uses acc tilt-angle measurement. Later I will try to add a full AHRS algorithm like the big boys use since it is better. (less delay)

-No PC necessary. All adjustments and multicopter type selecting is done with the LCD and buttons.

-The transmitter setup can be checked before first test. (channels and direction)

-low drift gyros.

-graded low-voltage-alarm, adjustable in 0.1V increments.

-motor numbering and propeller direction is visible on the LCD.

-Custom mixer.


It will become open source when the first update is available. But beware, it is still written in Evil Assembly!!


Here is a buddycode, get it for $19:

Y4 will be added. Also you can enter it yourself in the custom mixer. I will post more details on that later.

OK kapteinkuk, I realise you will open source it eventually but can you release the circuit to save me the effort reversing it? Pretty please?
What about the LCD? Can you point to any datasheets about driving it?
Any help is much appreciated.
I will send you a PM.

What are the flight characteristics with the autolevel? Do you still have control when it is on, or does it take control like an autopilot and level the multi until you turn it off?
Autolevel makes it very docile. But there is settings to adjust it.

It is available for planes too, but that combination is not tested. I will do it when I get more KK2's

Are the lines drawn between the motors not quite perfect in the picture, or is that just bad image scaling?
I will try to add CPPM mode. Round-off error

Why not ?

There are some configurable mixing possible, so maybe the 120S or 90S can be configured with the 1S

Looking forward to get this KK2 ... and looking to see the source code open up

e_lm_70

ps: The new chip in the KK2 has 2 serial port ... are these again unusable like it was with the original KK ? Looking at the HK photos, I even don't see the pin exposed for some custom changes ... at least old KK from HK was able to allow it ...

Rolf I love you man, why aren't there more like you!!!!!,thank you so much for this board even though this board is for noobs,it runs on a far better external 20Mhz osc,so I hope the geeks will take this more powerful system than the original board to new levels just keep up the good work man you are my inspiration >>>>>

So i plan on using this board on my spider quad. I am using a naza now but that will be going on my large hexa i just built.

What exactly can i expect from this one? Im not new to multi's, just new to the KK board. i eventually plan on going fpv on the quad and thought that this FC would be good for this type of flying.

that reminded me on this song: Jakatta & Seal - My Vision

There has been an arduino bootloader for Atmega324p developed as far as I know so even Multiwii could be ported on this hardware.

If there is gonna be some work done on the gps area by the good ol' kaptein, I suggest he works on this gps module: http://www.flytron.com/40-g-top-fgpm...ps-module.html

Since I a lot of osds use these modules and people already have them ..Plus this one has a good balance between performance and price.
In this case the gps functionality would be imo limited to plane use (because of the lack of baro and magneto on board)..And the chip probably wouldn't have enough room for all the code.

Hey kk please upload some videos of this new board in action I have to wait for my board to arrive but in the meantime i just want to see if this new board can give flights as stable as the multiwii platform,plzz upload some videos quick,,just want to see the feasibility of the new kk against the flight stability offered by the ardupilot 2.0 and multiwii projects,and one more thing 20MHZ external osc. should now be a licence for some hardcore hackers like happy and mike to modify this board for magnetometer/GPS/sonar and all the other great stuff...

The first 17 seconds is with the KK1, the rest of the video it is with the KK2: (Self-level is not used)

The annoying Mini UFO (6 min 1 sec)


Some more info:

- Each of the three gyro/acc chips has its own 3.3V Maxim low-noise voltage regulator.

- It has an option to use the Z axis Acc to dampen vertical movements. (not used in the video) Works very well in turbulent air.

- There is only one free IO pin, PortA0. It is tied to VCC, so a track must be cut. (it must not be used as a digital output during ADC operation) However, the ISP interface (three IO's) can be used with care as these is shared with three of the buttons. (For example, use only when armed, no buttons is supposed to be used then) Free output and input port can also be used of course.

- The gyros (IDG650 and ISZ650) has two outputs, 440 and 2000 deg/sec. It is selectable with a small solder jumper. It comes with 440 set.

- Output PWM rate is 400Hz.

Good work ! Very nice!
What about accelerometer? Is it ADXL335 or something better?

IDG650 gyros are no longer in production, but I hope HK has plenty of them .

Ordered one board. I will try to make a custom CopterControl board with these gyros .

My experiences with Maxim is that they are easy to get as sample but hard in larger quantities for production.
