Yes its normal. When high current devices like motors draw current there will be a voltage drop on the main power source, i. e. the battery. The more current drawn the voltage drop will be more significant.

I can see from the video that the rotating directions of all the props are reversed, that's why you feel strong wind blowing upward from the quad. Though rudder should be on the left stick plus throttle should be on the right when in mode 1, which is correct. All I think Duhjoker need to do is 1)swa...

Ok this is working for me. But what are the optimal settings for baseflight? - 115200 baud - protocol in and protocol out only ubx - which messages are needed? i like to kick out everything else or at what baudrate do i have to configure it so autoconfigure will work in baseflight? My understanding...

then my gps must have been shipped with off settings. how do i reset my gps? I can't find the original text for the method but you may try this - m . Except that your gps doesn't have a USB port and you need a FTDI cable/adapter to connect it to your computer this instruction should work for you. I...

Mine is a stock crius neo 6m. Never hooked it up to anything than baseflight. I first tried with default settings in baseflight and it worked. Then i've set it to gps_type=1 and since it doesn't work anymore. If i set it back to gps_type=0 then it is working again. Is it possible, that this gps it ...

hey all !! I am new to this forum and a first time user of Multiwii ( Nanowii) and i am having an error when i compile the firmware in arduino.. the error is shown like this "IMU.cpp: In function 'void getEstimatedAttitude()': IMU.cpp:189: error: 'GYRO_SCALE' was not declared in this scope &qu...

Ha, you're correct Patrick. This is such a low lever mistake I made, see how new I am in C++... After a look again, it seems that the & operator in the concerned if statement is just to perform a binary AND manipulation between the variable _i2c_gps_status and the constant I2C_GPS_STATUS_3DFIX, ...

justk1w1, I haven't get that far, and am just trying to complete my little 240mm quad project using Crius MultiWii SE 1.0 and the i2c_gps_nav board with sonar module. Are you trying to connect more rx channels via the nav board? That's interesting Would you mind let me know which branches you prefer...

I believe what justk1w1 mentioned about is the code at around line 424 in GPS.h rev.1548, which involves a move of the #if defined(i2c_gps_sonar) block to 5 lines below its original location, and put the 3 lines of code below the comment "//GPS_ground_course" above that #if defined block. ...

The code concerned here is in Multiwii 2.2 - not i2c-gps-nav

Great thanks to you justk1w1! You have helped me fixed my i2c gps nav board which was producing endless i2c errors. Now the sonar on my nav board behaves correctly as well!

Hi Jono91,

I'm setting up my nav board and is having a lot of i2c errors once I got 3D fix. Would you like to share your modified version of code and let me try on my board?

Hi Mis, Simple add void Sonar_update(); line to sensors.h file before "void initSensors();" line. I gave this a quick try, but it doesn't seems changing the error message when build. I have deleted some dumb questions, sorry for my noobness After some searching I seems got that calling an ...

Thanks alll, never mind. I'm a beginner of C++ and even greener at Eclipse. When I learnt the port away from Arduino has happened I was a bit lost, but still believes this is the correct way for MultiWii so I'm learning to live with it. Thanks clough42 for the wonderful Eclipse guide, I (mostly) suc...

add extern int16_t sonarAlt; //to think about the unit in MultiWii.h and void Sonar_update(); in Sensors.h manu Just tried, now I get this: E:\Multiwii\EclipseWorkspace\MultiWii\Standard/../src/MultiWii/MultiWii.cpp:1106: undefined reference to `Sonar_update()' make: *** [MultiWii.elf] Error 1

Multiwii (latest multiwii shared) does not compile if i uncomment one of the sonar (for example # define srf02) ../src/MultiWii/MultiWii.cpp:1106: error: 'Sonar_update' was not declared in this scope Hi, I have this issue as well. MultiWii doesn't even compile under Arduino too when one of the sona...
