MultiWii

I am setting up a simple quadcopter for a learner, and he only has a 4channel DSM2 transmitter. I would like to have Horizon mode enabled for him to make it easier, how can I enable it in the software as there is obviously no AUX channels?

A MultiWii port for the KK2 board would be nice. Need to have LCD drivers though to make it worthwhile.

What's the thing sticking up in the photo that look like a TO-220 package?

Nice, does it use the Arduino IDE and a compatible bootloader.

Wouldn't it be easier to just use one of the STM32 based flight controllers? They have more memory and run at a much higher clock speed than the Atmega328.

I tried velcro but it was no good, too loose. The best thing I have found is gyro gel tape

Magnetometer gets interference like you wouldn't believe from power wires. Many threads on it.

I just received one of those boards from flying-xys . My voluminous comments are at ... http://www.multiwii.com/forum/viewtopic.php?f=8&t=1598&start=40#p16169 I'd have to say that at this moment I am Not Too Happy. Bob Northwest Cutout Service Lol, you posted that in the Chinese IMU code de...

The color and writing looks like it was done by Crius. I would say it's an improved model by the same people. eg. it has a 328 on it where my Crius is only a 168 MPU. There is a new 40mm model of the Crius getting around too.

Never heard of ZMR are you sure you have that right?

Link please.

I would suggest a new chip too in that case. You don't really want a controller with a weakened chip suddenly falling out of the sky.

32bit looks interesting, but I will probably wait until the 32bit Atmega stuff starts hitting the market, as that's the one Arduino are going to use. They have the "Arduino Due" in beta testing atm. It's using the Atmega ATSAM3X8E 32bit chip. Pictures here: m Based on the ARM® Cortex™-M3 p...

please help.

Have you stuck a multi meter on the D3 pin of the Atmega chip and measures if there is conductivity to the D3 pin on the circuit board? It could simply be a bad contact.

Auto landing is important for AP or FPV when transmitter signal is lost or the battery gets too low. It will need something like a sonar to do the last couple of metres.

Check the GUI, make sure you are getting 100% throttle, check the battery make sure it's giving around 12 volts. 420gms is way too heavy for that size quad. I built a similar sized one recently and it came in at well under 300gms. The Gemfan 5.x 3 will be probably be only don't about 100gm thrust ea...

Very common try relocating your high current motor wires, make sure they are twisted. Get a compass and do some bench tests.

Should be yes as it is just a single sensor in its default orientation. Test and let us know. I hooked up the GY-521 IMU to an Arduino nano last night, just on the bench as a test. All I needed to do was #define MPU6050 in config.h and that worked. Just using the release MultiWii 2.0 verison atm. I...

The approach I will be using is to insert another micro controller between the receiver and the FC which will have additional sensors to auto pilot, thus leaving the FC to do the things which it already does well. ie. treat the MWC as a black box and leave it unchanged.

Has anyone tried hooking up a Inclinometer like the ADIS16209? http://www.analog.com/en/mems-sensors/m ... oduct.html

I also found a cheaper one, LCP-45.

Would and inclinometer simply be a double up on what the accelerometer is already doing?

I was just looking for ideas to auto calibrate the multi-copter.

+1 for the 1024x768 size - at least There are a lot of netbooks out there with 1024 x 600 resolutions. As netbooks lend themselves to being taken out onto the field it would be nice not to break the GUI for them. Things like Java apps become unusable when built beyond that native resolution. good p...

Sounds interesting. What kind of movements have you tried to automate so far?

could you explain how to setup DLPF ? There are some MPU-6050 LPF defines for the gyro in config.h perhaps that what he means? Specifically: //#define MPU6050_LPF_256HZ // This is the default setting, no need to uncomment, just for reference //#define MPU6050_LPF_188HZ //#define MPU6050_LPF_98HZ //...

I bought one of those Chinese GY-521 - MPU-6050 boards off eBay. I am hooking it up to an Arduino nano, I can't seem to find a schematic of the GY-521. Is the pin labelled VCC meant to take 5volts or 3.3volts? I see something that might be a voltage regulator on the board, but I can't make out the w...
