Hi, I would have direct command of the cam pitch with a TX pot assigned to AUX4 and working under MW 2.3 on my MEGA board( under 2.2 there was no issue ). So I see this post and I added the 2 lines at the end of Cam stabilize Servos , #define SERVO_TILT in Output.cpp , the following lines: servo[0] ...

Hi all Oled users, OK that is warm beer ! I tried to make my Crius V1.0 Oled working , i had just a snow storm on the screen. Then i tried to hack with different pins of the connector with no relevant results. I tried with a 1OO ohm resistor with success only at 25%. I tried with software mods, no r...

Hi i'm flying in mode 1 since a long time. I'm using this config, hope there isn't no error in there ! The profile select is a bit tricky in mode 1, perhaps some Defines in config.h can bring a improvment by swapping Throttle and Pitch ( mode 1 & 2) in the code of multiwii (#define MODE1, #defin...

@ nenno

try to comment analogReference(INTERNAL) , tie AREF to 5V (I suppose your board is supplied with 5V) and change the code like the previous post.
Nothing can break, if it's not working , take the old config anew.
Claude

flyman777

Hi nenno, if your sensor gives 5V by 50A, so the analogread input must give 1023. The voltage step is Vref/1023, if Vref is 5V so the step is by 5/1023 = 0.005V Your formula should be : ((Vref/1023)*analogRead)*10 , change that in the code you will have 50A reading: ((5/1023)*1023)*10 If you have 10...

Hi, for the newbees and others it happened to me something that I have not thought. I made a quadX sometime ago and absolved about 30 flights with no problems at all, Baro maintains altitude in 1 meter average, PosHold and ReturnToHome works with the params out of the box (MW v2.1). So today I mount...

flyman777

Hi, many thanks to Mahowik for his work. I tried the IMU_BMP085.ino (MW2.1) yesterday on my tri (900g) and after 10 flights I can say that it is a huge improvement. Never the altitude holding was so reliable and reproducible. My settings ended at PID: 8; 0.010; 50. The altitude hold is very strong i...

flyman777

I agree entirely with Alexia. It's now important to improve the baro mode and GPS. Don't waste your time with LED blinking and so on. The basis must be clean and safe with simply settings before charging uselessly the config.h with so much options. Remember, the origin of MWC was an arduino 328 and ...

flyman777

OK pm1, thanks for the reply.
I will try your mod in FC as soon as the weather will become better, it's stormy yet here.

flyman777

Hi @pm1: perhaps your right I tried the Poshold with genuine i2c_gps_nav rc2 from EOS but my copter speeded up after a few seconds forwards and backwards and begin to tilt so I must switch off the gps for avoiding a crash. In static conditions, there was also a huge drift over 50-100 meters in about...

flyman777

Hi, I had drastic drifts about 200 meters with my i2cGPS+LLC from Drotek. This was absolute unflyable. So after reading pm1 post, I tried his solution: x_target_speed = constrain(x_target_speed,-100,100); ... I leaved my board in static position about 30 minutes, the result is bluffy ! Only drifts a...

flyman777

Hi, I make my boards myself and it was more convenient to take D8 as input for a Promini. The Buzzerpin has then been moved on D12 , useless if you have other gyro+acc then WMP+NHK. So I modified the def.h accordingly. It works with MutiWii 2.0, 2.1 RCAUXPIN8 + BUZZER must be defined in config.h Att...

Hi all, Finally i got work the last gui, no more blackboxes ! Thanks to the tip given by Alex and Kad, I reduced the hardware acceleration to one before zero, reboot the PC and it is. I noticed that I must plug the FC board to USB and ARM the copter so that the AUX boxes and RCdatas appears finally....

flyman777

Hi Alex, unfortunatly, the gui is not working well for me. The AUX checkboxes and RC data bargraphes doesn't display on the screen on my PCs under XP 32 bits ( the same with Ubuntu), always black boxes. Is there a solution ? All MWConfs till dev20120605 worked well. What is the matter ? Sans rancune...

flyman777

Hi,

I updated controlP5 (last version).
It compiles now without any issue, but the checkboxes for AUX doesn't appear on the screen.
I have no solution for the moment for running this dev with Win XP.

Hi,

I tried to compile MWConf_20120622.pde with Processing 1.5.1 and I got an issue, see the Zip file.
Can this been the strange behaviour of that dev.

Claude

flyman777

Hi all, I come back, I tried to run the last MultiwiiConf_dev20120622, with no success. The program starts but the AUX check boxes don't appear on the screen. I'm running Java JDK_1.7.4 on my 3 PC's under WIN XP and I have always the same issue on all them. The Conf's (1.7 -> 20120522) are running w...

flyman777

But for using WinGui, you must have installed .NET
Otherwise, MultiWiiConf can run on all platforms that support Java and is lighter than WinGui.
This does not discredit the work of EOSBandi, his software runs very well.

hi,

it will be fine if you can integrate the saving and loading the whole copter config in a file, so I must no proceed printscreens to save a config and try another one ( like it is made in MultiWiiGUI).

Hi, I wish you a lot of success for your trials. I decreased the D factor from Roll & Pitch to 14, so my tri don't no more overshoot in roll or pitch. Flight training is important mainly in the learning phase, fly so much you can, have 4 or more batteries available. If you are a RC Modeller that...

Hi, You'r right. I did that with POWERPIN D12 changed in BUZZERPIN in def.h because I'm using D8 as input for AUX2 on my proMini board + AllinOne.

Hi Doblao, that can be that your bootloader is out. I had the same problem with an UNO 328P and I must reload the bootloader. See Arduino pages for this. I reloaded mine with an external programmer (WinPic800) with AtMegaBoot168_atmega328.hex (in bootloader file from Arduino 1.0) and reconfigured th...

Hi Doblao,

that can mean that your bootloader is out and is not reponding.
Perhaps you must reload the bootloader, see related Arduino's pages .
Good luck

Hi, I think for newbees that would be awesome to have an automatic config by using AUX2, not everyone dispose an PPM sum receiver. The IMU boards are more and more used , the prices are sinking, so we don't need anymore the POWERPIN output. BUZZERPIN is on the contrary usefull for low batt warning, ...

Hi, using a IMU board AllinOne + Promini , I needed a AUX2 entry and don't need further the POWERPIN. In this context, I changed the pinout for Buzzerpin in def.h and removed all occurences of Powerpin in the sketch. To make it more universal, I introduced some #if #endif in the sktech: - so RCAUXPI...

hi, it is not desirable to connect more 7805 paralell. No datasheet does evoke that possibilty. Effectively it's possible in a circuit but not recommanded. You must have ballast resistors (or diodes) about 1 - 0,1 ohm to perform the voltage balance between the regulators. That is only possible on a ...
