"Harry, little update. I looked through my stuff and have come up with a few options, the best two are; the arduIMU with the CERB40 (STM32F4 processor), or the STM32F1 IMU (same sensors as the APM 2.5)...
Wife just left for Texas for 10 days so I…"

Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"I managed to get Fabio's( poor guy, RIP) FreeIMU library running on the ArduIMU and that needs the I2CDev DMP stuff. He's accessed the DMP of the MPU60X0 and somehow got it to play nice. The processing GUI works sorta…"
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"I say it might need a different sensor board. The ArduIMU should be able to connect over serial if I can figure out a few things. I tried running the I2CDev DMP on it and it wouldnt connect to the MPU60X0. I could connect to the…"
Jeff Smith replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"I'm still interested :-) but it seems you are doing all the work LoL :-)
I have a few 10DOF sensor boards, I'll see what I have a pair of and shoot one to you to play with. I have a single 10DOF that has a STM32F1 processor, if I can get…"
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"Jeff, if youre still interested in where this might go. I got PPM to work on the pro micro. I have a feeling I'll end up getting a whole different sensor board that runs on I2C. Sparkfun has a few, but I'll be stuck if I…"
Harry replied to Al Toma's discussion Discussion Group for ArduImu V3 Applications Only?"According to the Invensense datasheet, they're identical except the MPU6000 also does SPI and the 6050 only has I2C. Now, I dont understand enough to manipulate code to do much but they're supposed to have same register adresses and…"
Harry replied to Al Toma's discussion Discussion Group for ArduImu V3 Applications Only?"Has anyone tried to get the I2Cdev MPU6050_raw.ino to work on an ArduIMU? I tried and it wont connect to the sensor on I2C, says connection failed and nothing but 0's for the sensor readings."
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"Jeff, I hope youre good.
I thought I'd tell you that the pro micro board you sent me from sparkfun will also run MultiWii. I made a minor accidental discovery with it too. I loaded the code and the started the GUI and when I…"
Harry replied to Al Toma's discussion Discussion Group for ArduImu V3 Applications Only?"Funny you should say that. I did that and it had issues, that's why I'm trying MultiWii to see if the issues go away but I'm having a tough time."
Harry replied to Al Toma's discussion Discussion Group for ArduImu V3 Applications Only?"Al, your .txt file has been useful to me. I'm trying to run MultiWii on the ArduIMU. I've been trying to get it to read PPM on D8. I've learned that PORTB bit 0 is pin 8 and that A3 is PORTC bit 3. I've…"
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"I still cant get it to read PPM, but I am able to get it to output to a servo. I tested each PORTC A# for output and it works. I'm tempted to try to use the original PPM Rx sketch by Jean Louis and shoehorn it into…"
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"That's cool.
I tried to get MultiWii to read the Rx. D8 is the only pin for Rx on the ArduIMU and I havent figured out how to get PPM to work, but I can get it to read a single channel. It has something to do with…"
Jeff Smith replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"Well, I ended up "volunteering" my weekend to the wife, we camped, hiked, and bird watched :-) It was a good break but kept me away from the computer LoL.
The multiWii thing does interest me as far as similar bits and pieces. I've…"
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"That'd be great, Jeff. Dont forget to fly your heli too.
I have to repair the tricopter again after a prop flew off and flipped it. I was only about a foot off the ground but it bent the good arm and now I have to get…"
Jeff Smith replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"Awesome! I think I can help with this :-)
In my studies of C code and embedded programming I came across this. I will make the time this weekend to sort out the PIN numbers vs. the Eagle files for the IMU and see if I can correct the code you posted…"
Harry replied to Harry's discussion Trying to adapt Jean-Louis' tricopter code to IMU V3"To change the pin assignments isnt easy. Take a look at this:

The Next Sensor was Invented by Vikings
Posted on March 11, 2013 at 4:00am 2 Comments 2 Likes
There have been discussions before calling for reliable and accurate alternatives to GPS. The Vikings may have had the answer without knowing the physics. They were adept navigators at latitudes where frequent cloudiness and low sun angle(winter) could have made direct observation of the sun difficult. Legend has it that they had a magic stone, called a…

Here's the plane I will install my Arduimu and Ardupilot(legacy) into. I still need to build a motor mount and wind the motor. It should be stable as it is based on a previous version which was very stable. I'm aiming for 10-12 ounces AUW and around…
