MultiWii

Hi Alex, this is true but it is just useless for the YAW-Channel - for the Roll and Pitch-Channel the code would be the same like now. for(axis=0;axis<2;axis++) { uint16_t tmp = abs(rcData[axis]-MIDRC); #if defined(DEADBAND) if (tmp>DEADBAND) { tmp -= DEADBAND; } else { tmp=0; } #endif uint16_t tmp2...

Ok, this might be the final version. The code is even shorter than the old one. multiwii.pde (line ~246, right above the old deadband implementation, which then must be deleted) for(axis=0;axis<3;axis++) { uint16_t tmp = abs(rcData[axis]-MIDRC); #if defined(DEADBAND) if (tmp>DEADBAND) { tmp -= DEADB...

Hi Ziss_dm, I was trying to get a clean implementation without lowering the maximum signal on the axis where deadband is used. This is why I use scaling and not a simple substraction. I generally agree that there are more simple ways to get a deadband. But I would still suggest to apply the deadband...

It is really a pitty that no one seems to check that code out! The good news is: As I was very sure it would work flawlessly I testet the code in flight. 12 LiPo-Charges later I now can say: You ALL should try it! No TX is perfect and sends perfect Mid-Signals when the Sticks are centerd. The values...

Hi Community, I recently noticed an issue with our current Deadband feature. In the picture below you can see what happens to our rcData when it gets processed by the deadband code. deadband.jpg As you can see there is a "step" in the rcCommand. This step causes a significant loss in steer...

This tool is great!
Especially the feature to save PID-Settings with a short description to the sd-card is perfect!
Thank you!

I also have the problem with the 256Hz low pass! I was not aware of my Quad having this problem (I thought some older SW-Versions also used 256Hz LPF). Now I tested rev214 and had a crash because of oscillations. Within two seconds the quad was uncontrolable and flipped. My PID is 3.0 - 0.030 - 13 a...

I am going to try it, but I think it might be tuesday until I have enough time...

I'm not satisfied.. The issue with the gyro "passing out" for a moment when stopping from fast forward flight might be a little better now but I had still problems in flight-situations where the stabilisation has a lot of work to do like during fast direction changes (narrow turns with qua...

Hi Sandmen,

I'm really interested in your Source-Code to make the software campatible with the latest dev-Versions of the MultiWii-Software.
Would you mind emailing me your code?

Best regards,
Peter

My config is Quad+ with ITG3200 and a LLC. I use the 3,3V regulator on the Paris V3 Board.

In my case it occurs in acro-mode. (I dont use level-mode.)

Hi Frank, ok I tried the library you posted and implemented it in the MultiWii-Sketch. I edited the Pin-Mapping to Pin 3 (Front-motor-esc) to test the sketch. At first it worked and the startup speed was set to "very slow" . Then I tried to go a step further and use a variable for the pin-...

Hi, I was about to post the same! I recognised this problem with some dev-versions released in the last six weeks or so. I was never sure about it but after todays flying with the dev20110710 I am absolutely sure. I fly with P=3.2 I=0.033 D=11. My QuadroPlus flys stable with this settings but after ...

Now I have broken down the errors to their origin. The problems I cannot solve are all related to the following typedef: typedef struct TPC_settings_t_ { char brake; enum TPC_battType_t battType; enum TPC_cutoffType_t cutoffType; enum TPC_cutoffVoltage_t cutoffVoltage; enum TPC_startMode_t startMode...

Hi Frank, thanks for your reply! When trying to compile the code with the Arduino IDE I get a bunch of errors: ESC_Config:18: error: variable or field 'TPC_loadDefault' declared void ESC_Config:18: error: 'TPC_settings_t' was not declared in this scope ESC_Config:18: error: 'x' was not declared in t...

Hi folks! I found a very interesting article about programming turnigy compatible ESCs via an ATmega328P running at 12 MHz. http://frank.circleofcurrent.com/cache/escprogrammingcardhack.htm In the MultiWii-Project most of us use the same Processor, but at 16 MHz. My programming-knowledge ends when i...

Hi to all developers! I found an error in the Config-Tool of the last dev-Version (dev20110705). I set the Throttle PID attenuation to "0.20" and hit the "write" button. When I then click "read" everything seems to be ok - the field still shows "0.20" But when...

This is such a grat App!

Please keep developing it!
I hope you implement a feature to save a few PID configs on the phone.
But right now I'm also really happy with the features included already

Best regards!
