Before we lose the subject of this thread... Today I successfully tested Patrik's latest RTH code on my Flying Wing! The wing returned successfully every time (at least 5 times) from 100 to 150m from home and started to circle around home point. I did my tests into couple directions (into the wind a...

I was surprised that simple transition run -> break -> startup has quite good response and startup is relieble. What ESC/motor/prop combo have you tested? In my case Tgy TY-P1, KDA 20-28, 10x4.7 SF props startup after transition is much less than 100% successful. Tested on bench and much slower tra...

@Roman: I still have pass-thru enabled on my TX but in my case it is not really useful (never used) since my FW is now FrankenWing and it is not joy to fly it without gyro/acc support and specially hand-launch is (nearly)impossible without gyro support so after first starts/PID tuning you can remove...

I'm traversing posts thru "View active topics" link and quite often find topics thrown into random section (not rarely simple Arduino questions asked inside 32bit sections)

So yes I agree that some kind of moderation would be good.

Hello, promising video! Patrik: - Should I set #define GPS_RUDDCORR to 0 for Flying Wing (since it has no rudder)? - I have not yet tested current (before today) version, but with version from the end of the last year my wing often went into spiral turn (uncoordinated turn with losing lot of alt.) w...

Hi crashlander, Currently not, but it was easy to do, so I have created brunch "wii-esc-ng-3d". Which works surprisenly well.. If you want to test it - you welcome. ziss_dm Thank you! Any tips how to compile/configure: I'm using HK F-20A and F-30A so define of _BS_NFET is correct but what...

Hello!
With latest Warthox stunts in minde (viewtopic.php?f=9&t=3193) I'm asking if WII-ESC is capable of mid-flight reverse switching and if yes how to do proper eeprom (and maybe MultiWII) configuration for it?!

Really Cool!
Any chance to get those mods for testing?!

@gompf-2: So if I understand correctly time measuring functions in Energia are broken and your/TC's correction fixes it?! I have problems with simple delay() and/or millis() it only works with Micro's. From your fix I do not understand what you mean by "- copy the new wiring.c to the lm4f"...

What ranges are we talking about here? OpenLRS seems to use frequencies between 400 and 460 MHz AFAIK EZuHF uses 433 (m) on 600mW that is 60 times more than specified in m (on page 4) and most probably it normally transmits more than 10% Duty cycle. But the project is interesting since it does not ...

@Gimbal Thank you for answering!
I just found RCGroups thread about same issue: http://www.rcgroups.com/forums/showthre ... 04&page=51
After just removing burned cap the borad came to life

(LED is on) and it seems I'm getting some 2.36V out of regulator (65z5).
Have to change that cap and probably regulator also....

9.6k bps data rate is not much.

It can be set to 19200bps but not higher!

Alex I really like your idea/project and I'm looking forward to it.
If you managed to get it working with eg. APC802_43 we could get cheap LR system with telemetry.

The sliders being on the wrong channels is an easy fix. When you uncomment the define for ppm in just swap around the order of the channels. I do not use PPM and the wing fly just fine so channel mapping (TX/RX -> MWII) is O.K. only channel sliders in GUI are wrongly mapped (MWII -> GUI)! Regards A...

there are a lot of user, they only can change the config.h! Carsten I believe that not exposing too-much data in GUI is a good practice. There is also no special reason to invent too-many MSP commands just to read some rarely used data. But maybe it makes sense to move some/all of debug values into...

Often that kind of behavior can be tracked back to excessive vibrations.
Check/balance props, motors, check screws ... sometimes multy arms are to soft/long.
Increase LPF settings for your specific sensor (probably ITG3200 on your board).

BT module is basically just wireless serial cable and as such you don't need no code to use it! BT module is connected to Arduino serial pin's and when bound to computer it will create new (virtual) serial port that you will select in MWII GUI or MWII Windows GUI. Concerning VCC and GND those are ju...

When arming, the failsafe account will be check to see if stable signal available. Other wise, it refuses to arm. But after (and before MWII FAILSAFE_OFF_DELAY) TX signal is restored you should get full control back and in my case I only get some very delayed response and/or sporadic behavior. Rega...

crashlander

I disabled failsafe for RCSERIAL since I was getting strange results like: unable to arm my multi in the first place, unable to get full control back after failsafe was trigered and signal returned (failsafe was only partially canceled)... I was testing smart failsafe with nhadrian's code from that ...

crashlander

TX sends commands with constant but very slow rate (eg. 10Hz) when there is no need to change anything (or changes are small) and switches into higher rate when there is strong stick input (need to do big change). But with that principle you can get into situation that slow sending rate is considere...

For FAILSAFE only. What about just in config.h change (or some other higher value): #define FAILSAFE #if !defined(RCSERIAL) #define FAILSAFE_DELAY 5 // Guard time for failsafe activation after signal lost. 1 step = 0.1sec - 1sec in example #else #define FAILSAFE_DELAY 10 #endif Again if there is no...

crashlander

@Eric: Can you explain the usefulness of repeating same signal (but sending just repeat)! Since original MWII implementation keeps value of last MSP_SET_RAW_RC forever if necessary! In other words if nothing has changed on TX there is no need to send anything!? I'm using 50Hz in fast mode to get qui...

Hello!
Interesting project indeed!
@alexmos: use of brushed motors seems mechanically/electronically simpler so why you chose brushless (technical reasons or just availability)?

Hello! - use Scrat's advice (of using newer version) - make sure you are using recent version of Arduino (at least 1.0.1) - make sure Arduino opens all .ino files from MWII directory (13 tabs/files) - make proper defines in config.h (at least Multi type, board, TH minimum) - select proper board in A...

Setting to Arduino Mega definitely will not help on Crius SE board (we are not speaking of AIO Pro here).

Hello, on 2.1 you can use only one (first) serial port for connecting GUI and you set that port to desired baud, so you must connect your 3DRadio to RX0/TX0 (that one is AFAIK also shared with onboard FDTI/USB). On later _shared verisions you have option to use all serial ports.... and set speed for...

crashlander

Slightly off-topic question.
Would it be hard to implement failsafe routine also for RCSERIAL?

Basically we should be looking for timely arrival of MSP_SET_RAW_RC frames and if those are missing for short period (eg. 1 second) MWII should activate failsafe.

But be careful since those (flashed) ESC's are lacking soft start that is almost mandatory on CP heli.

Hello, due to fast moves I can not tell if the direction of movement is O.K. (but it seems to be) otherwise it looks as it should. It is normal that Yaw servo compensates for yaw movement. So the next logical step is to do "hand test" with armed (and some TH) to see if it counteract your m...
