I just flew R5 from Adrian on a Crius AIOP with Ublox 6M serial GPS. Remarks: -Alt Hold works as expected -Vario works also but some times has some bumps (tried throttle max and while rising the speed was not constant relatively) - The ALT HOLD position of throttle stick is the position in where ALT...

dramida

just uploaded R 5 to my tri and i am glad to see the latest release R1298 is present

good job . Now i am leaving to fly it:)

dramida

My "expensive" toy costs about 150 USD and i am ready to crash it every time it needs to evolve this software, so please, Adrian, don't bother to respond to all. And of corse, i need your R4 file as i downloaded only R2.

dramida

No, that Alt Vario test with Adrian's software is scheduled tomorrow, the day is too short

But as you well noticed, there is a basic Alt Vario implementation also in R1298 software. I have to test Adrian's more featured altitude mod before making a judgement about altitude vario implementation.

I just flew R1292 with GPS prediction filter and new mag calibration routine. I am using Crius AIOP with Ublos Neo 6M binary protocol GPS. In my opinion the positioning is twice as better than previous as i could stay on GPS PH on a narrow street between buildings. Anyway i made a test with my 1050 ...

Hi Folks, I just committed an update to the GPS parsers. it includes : - updated initialisation for MTK gps modules correct EGNOS init and set navigation threshold (Thanks for Crashlander for the help and test) - Added MTK binary protocol for both versions of DiyDrones binary MTK firmwares (v1.6 (A...

dramida

Great news Adrian! I'll test it today along with Eos patch for mag. Best regards, Mihai.

dramida

I just committed some rework on the HMC5883L gain calibration (init). The code is based on Fabio's FreeIMU code and I think this is as good now as it could be on this platform. After some experimenting I decided to keep the current offset calibration method (MAG DANCE) since the ellipsoid to sphere...

dramida

Bart, i like the new dashboard! Bigger text is better. How about setting a new home on map and then navigating to it? I made a mod on crius BT and i replaced the pcb antenna with a 30mm wire (lambda/4) and i had continous link until 174m with an galaxy s3. If i could use an external BT with the same...

dramida

Have you tried to connect with other android devices? I had a Samsung Galaxy S9000 witch i couldn't make it connect with Crius Bt regardless of what application used

dramida

The code is in MultiWii Controller already, you have to define one option witch allows to arm copter with motors stopped and they will spin only when you rise throttle. If i remember the code is #define motors_stop . I tested the throwing and somewhere on yaw code is an overflow. Here is the video:

I agree using MinimOSD with rushduino.I also bought one at 18$.

dramida

Helo Bart, i saw a new release of EZ-gui on my android. Thank you

Can you tell what changes it has?

dramida

Hi all, I tried the r1282 with the "vari" based altitude hold code. OK, basically I can move up or down, or stay in position. But it is far not exact . I modified the code ........... BR Adrian Adrian, my test with vario altitude mode with Mahowik code where look promising in altitude hol...

dramida

Hello Eos, a while ago someone called Mahowik achived to control the variation of altitude with a P-D loop.

Here is the result http://www.youtube.com/watch?v=7Sa-oyJ4Ljs

The code used is in this archive:

rssi on channel 2 is pwm signal. It is meant to be read by OSD or other pwm compatible device like FC. Ofcorse the rssi is coded in serial downlink also. I am not shure if i understood your question.

dramida

Hello EosBandi, please bring Santa earlier this year and write a single way-point (x-y-alt) implementation with WinGui.

dramida

Using minimum hardware OSD with Rushduino firmware on multiwii is easyer than we think: For RSSI and voltage/ current indicator we don,t need to use the analog inputs from rushduino MCU atmega 32 and to hard-wire the board to battery and receiver. All we need to do is to use MSP voltage, MSP current...

dramida

Last fw version of Frsky D8R II receiver has rssi on ch2 as pwm and ppm on ch1 (if you put a jumper between 3 and 4) OK thanks, I´m going to look into that. Is this the one? m You can find the new software witch works fine on all my receivers (with RSSI and PPM sum) in BETA TEST SECTION tab called ...

Hi ezio, i never used logging as i am an end-user. What bennefits brings logging to a flyer, not developper.

dramida

Hi eizo, i really like your android aplication, it helped me so much these days. What do you think about a feature like: put 3 secconds your finger on the Google map, enter an altitude, press execute, and the copter goes twards that point if you turn on "GPS Home" One of my customers needs...

I will test it for you as i am not satisfied with current vbat implementation.

Here you can buy MinimOSD with 18$

That is really nice. How does it work? We connect the BT device inside the Radio transmitter with frsky module? And the rx-tx ports of the radio receiver on the copter are connected on a free serial from FC@ 9600baud

This short range high accuracy button radar could revolutionize how the uav perceive the world

Multiwii is an open source project witch reach its maturity. It integrates all sensors you need for autonomous navigation. RIght now MWC is on the verge of Waypoint navigation through telemetry. You can contribute to that.

dramida

Welcome aboard Isac. You can use #define rcserial option in config.h to enable serial control over MWC.

dramida

I see so many interesting features outside this topic, many nice & kind developers, please help they test & improve, instead of waiting, arguing, asking for more here. +1 And one other fact: Multiwii got this rising momentum due to lo cost-high availability hardware doubled by an enthusiast...

dramida

I can't belive that Mahowik, Timecop and Crashpilot1000 argue each other for hall of fame MWC codding. It's room for everyone to be important in this project: gps waypoint navi, autolanding , failsafe routine, adding numerous improvements - lists are there,

dramida

I use Frsky receiver with latest software for D8R II has PPM sum on CH1 and RSSI as PWM on CH2 (only if you bridge CH3 with CH4 by a jumper, otherways it behaves normally). OLRS has the same signals.

dramida

Reading the RSSI in PWM/analog format directly by FC will be useful for:

- Automatic go-back or go higher routine in case of poor signal (not lost signal)
- new MSP command to help GUI/ OSD to display rssi

dramida

Mahowik, move your ass back here and stop fooling around with binary distribution nonsense witch contradicts the GPL licence. If you are not working in a team, you'll end up wasteing your time. If you want to do some good money with Multiwii, offer technical support for local/global users and/or do ...

The OSD hardware is already here at 18$, and i mean MinimOSD :

http://www.goodluckbuy.com/on-screen-di ... apm-2.html

Can be rushduino be used on the same hardware as minimOSD?

dramida

I don't get it: After successfully implementation of altitude variation control by Mahowik almost two weeks ago, the shared trunk code remains the same. Let me remind you how nice the altitude control works, here is the video: m And in case the code is no longer availabe on Mahowik branch, i attache...

dramida

The altitude control works very good, the only issues where about arming/disarming that could be inherited from main trunk.Specifically, on Crius AIO PRO board, quad mode with camstab, buzzer, GPS, Vbat- enabled, i couldn't arm the copter from the first time, i had to try several times. Also in Alti...

dramida

Hello, I noticed that latest MWC zip file that i previously tested it was removed from Mahowik branch due to some unresolved "issues". Do we have anything new to test this coming weekend?

dramida

You are right about different settings for different copters (Power/weight ratio regarding Pos Hold) but default P is 2 and i found that a value four times greater is far better for a precise position hold and a reduced wobble when yaw-ing.

dramida

I want to share a good finding about GPS pos hold PID parameters. Multiwii inherited the PosHold algorithm from ArduCopter through EosBandi implementation. We took the values from AC2 and ported "as is" to MWC. We saw the setings "works" and we let them more or less unchanged. To...

Has anyone the KiCad schematics of Rushduino?

dramida

BUG found in this useful amazing android application EZ-GUI :
In "dashboard 1" menu, copter mag arrow has Y axis invrted: When copter is facing north and rotate copter to the right (East) the mag arrow on my phone rotates twards left (west)

Does anyone tested the follow me function?

dramida

I tested in-flight altitude hold and in does a far better job than previous R1170. For me was good enough the altitude hold behavior during fast flight. I can see it compensate the throttle when leaning also. Improvement: setting hower throttle to the point where Alt Hold is activated is strange , ...

dramida

I think we have a bug regarding Vbat for 4S lipo: I can't change the voltage prescaller in software so regardless what VbatSCALE value i wrote, the voltage shown in GUI stays the same. Am i missingng something? What it does VBATNOMINAL...is it really necessary? Do i have to erase eeprom to change th...

It works fine that release. One point to mention, i observed in this last version that arming the copter with yaw right in not always working. Sometimes when i try to arm the copter, i hear a very short beep and green led from Crius AIOP blinks also shortly. Nothing happens after. After several ate...

dramida

And here is the video in witch the variation of altitude is controlled by throttle stick position, regardless of the mass and power of your copter like this: Throttle at about 50%= altitude hold Throttle more than 50%= altitude is increased at a rate proportional to throttle deviation from middle po...

dramida

I just tested the latest archive release with vario. It works very good with default pids. The video will post this night. A must se video with gps hold and vario baro mode and autolanding.

dramida

Anything new to test and make a video in this area?

dramida

I want to build this OSD, i need an clear schematic, a list of components and a PCB in 50x50 square, is anywhere i can find that? (i'll build another one to donate here )
