Setting up MS5611-01BA
Hi all, I've just bought an MS5611 board from drotek: m I soldered the jumpers as showed there, and for CSB-high (0x76) I have a Quadrino board with onboard BMP085 and I wan't remove that sensor (that's why I'm using CSB high because CSB low would mean the same address as for BMP085, if I'm right) A...

Re: I2C GPS
Hi,
first that was the idea. But once we have a secondary processor, why don't use its resources? It can do the complete calculations, later for waypoint flying can communicate with a memory card, etc... and provide the distance, direction values for the primary unit only.

Re: I2C GPS
I saw only one but was completelly useless, just some copy-paste from MW-code... I posted also my try-out but I'm not a programmer so it didn't work at all. Here is our idea about the software solution and basic working procedure: http://www.multiwii.com/forum/viewtopic.php?f=8&t=649&start=1...

Re: I2C GPS
Good idea.
But I think first we should have a software solution that really works. With an arduino mini or nano and a GPS receiver software can be tested.

Re: GPS integration
My oppinion is that first should be more than enough if it would do the same as EOSBandi presented some posts earlier. If RTH is activated, it starts to move towards to home position. When it reaches the home position it stays around there. For position hold, it also has to be able to go back to pos...

Re: GPS integration
Following the idea with secondary processor and i2c, position hold and RTH is the same situation, only coordinates are changing, because once you reached the home point you should stay around there. So the excersise is the same but only when on hold mode (I meant position hold) you starts from the d...

Re: GPS integration
Hi guys. After many hours of trying I had to realize that I should spend on lot of time to learn the programming basics properly, and figure out how multiwii code works. In lack of this it is almost impossible to do finalize my idea. But also I think it would be 2-3 afternoon job for somebody who kn...

Re: GPS integration
I suggest this GPS receiver: m cheap and works great, I already have three of them woth different OSDs. So, could anybody help me integrate my i2c GPS idea into the multiwii code? I think many of us with arduino mini would be really interrested in because then they only need a receiver, an Arduino m...

Re: GPS integration
Hi all, Finally, we rewrote the whole i2c GPS code. Here is how it works. There is a 10 byte block definied with GPS_fix, numsat, distToHome, dirToHome, distToPos, dirToPos. So it calculates the direction, distance from home position (home) and stored position (Pos, for position hold). On request fr...

Re: GPS integration
Hi everyone, I found Michael Maslik's work about i2c GPS integration. I'm planning to use a separated arduino nano for GPS serial reading and then sending via i2c to main board. I found a useful code by Ben_der on fpv-community.de for this. Unortunatelly, Michael's integration is only for the 1.8p1 ...

Re: HMC5883L YAW problem
I'm googleing continously and I found an article about something similar issue. Here you can read that HMC5883 and HMC5883L are different, there is something difference in adresses too. I think the multiwii code is for HMC5883 not 5883L so could this be the problem? Could somebody check it out? (I'm...

Re: HMC5883L YAW problem
I don't think so because debug2 stays 0 and everything just works fine except MAG YAW! But this is the situation from the first time.

Re: HMC5883L YAW problem
Yes, the other two axix works as it is described. I tried to swap two lines in mag raw adc, (change y,z axixes), and then the y axis number is constant, the yaw moves. So mainly it looks like to me that multiwii reads out a constant value from the sensor in raw2 and raw3. But I can't imagine why.......

HMC5883L YAW problem
Hi all, I have a quadrino adv. board in a mini hexa. My problem is that in the GUI the MAG_YAW was 1 or 2 constantly. First i thought it is a sensor problem so I removed the sensor from the board. Then I attached another sensor on a break out board to the i2c port. Now, the MAG_YAW is 51 or 52, but ...

Multiwii level back-drift
Hi all, I have a mini hexacopter with Quadrino adv. board, and MW1.9 on it. It works perfectly in acro mode, holds it's position in wind and calm air too. But in acro-mode, after flying in a direction for a while, it has a terrible back-drift. After back drift, slowly it returns to level. It is the ...
