"Thanks Robero.
I am working on a light ground station on Matlab to plot in real time several paramaters but there is still a lot of work to do. In the same time I am working on the VTOL aircraft which should flight alone soon.
Then I will have…"

"Hi,
I started few weeks ago to make a cleaner code from Jose's mini quad project. I use a library for PPM decoder and command (through a Pololu Maestro but I am planning to use the ServoTimer2 library). The code is more generic (for PID and…"

"I uploaded sample datas : http://code.google.com/p/easy-imu-pilot/source/browse/trunk#trunk/T... The format is csv.
The bigger one is 200 000 samples at 107Hz so around 30 minutes. I also uploaded 50 000 samples at 160Hz (using a TX buffer) so…"

"Hi,
You made a great job! Do you plot the whole file? Because there is around 6000 samples so at 150Hz it should last 40s.
Could you try with the attached data file? It is in presence of noise.
Could you also try with right shifting (instead of…"

"I made some experiments last week. This graph shows the sum of 16 gyro samples
As you can see there is a lot of noise. If you right shift it 4 times, you remove a lot of noise but you keep the ADC resolution of 10bits. (so around 1°/s).
On the…"

"Hi,
I made several tests today. I read 16 ADC samples and I sent it to matlab at 20Hz (I also tried 100Hz but results are the same). Then I computed the mean and the variance for each sensors and for several right shifting. (0 = raw data, 1 = divise…"

"Hi,
This is my modification of the ADC reading. It took 16 samples to increase accuracy to 12 bits. However you also have to change your calibration values because output is now between 0 and 4095 (and not 0 and 1023).
The bandwidth is 83Hz. If…"

"Hello,
I used this IMU on a flying wing and it works great. I have some remarks and suggestions:
-You read 8 ADC channels but 6 is enough. With an ADC clock at 200khz, 6 channels and 16 samples you can have a bandwith of 80Hz and a resolution of…"
