Jordi,

Your Kalman implementation looks to be identical to tilt.c…so…

How do you solve lateral acceleration? In an aircraft z may remain constant (coordinated turn) and y or x may change proportionally when skidding (lateral acceleration) or forward acceleration or decleration. 5DOF+K-filter interprets lateral acceleration as pitch up/down (climbing, diving) or skidding )(roll in opposite direction of skid).

Jordi,

Thanks for the great job
Please let us have a link to the Labview code

greetings from Grenoble, France

Jordi,
Congratulations for this project!
But the link (http://jordii07.googlepages.com/ArduIMUFinal.txt) is not work... Could you send me?
Thank you.
Erick Netto.

Hola Jordi,
Felicidades por tu trabajo!!I hope you can help me. I'm trying to use a 3 axis accelerometer and a 3 axis gyroscop to track the movement of my arm. But I have doubts when setting the values of Q_gyro and Q_angle. The problem is that if I use a frecuency of 150 Hz to get the values of the devices, 6'6mseg, the minimum value of Q_angle I can use it's around 0'02. If I use values below I can't follow the movements of my arm because the angle value goes to infinity. However, when I use a frecuency of 50 Hz, 20mseg, doesn't matter what value I use for Q_angle, I don't have this problems. The question is, why this happens, and how I know what values I have to use for Q_angle and Q_gyro?
Thankx for your time.
Ion.

Can you provide the LabVIEW Code with kalman filtering?

Great job!!

Could you send me the labview code??

Thanks!!!

Hello Jordi,

are you still working on your ArduIMU project, everything I see seems quite dated now?

Bueno jordi lo primero, felicitarte por tu proyecto la verdad es que es asombroso. Estoy trabajando en un proyecto donde quiero impletar un filtro kalman utilizando tambien un giroscopio y un acelerometro para conseguir equilibrar un robot de dos ruedas. El problema es que trabajo con los programas Proton compiler y Pic basic. Por lo tanto me gustaria poder pasar tu cógigo kalman a alguno de estos ya que el tuyo esta c. Si es posible me gustaria que me lo enviaras en español para ver si puedo entender el filtro kalman ya que lo veo complicado. Si es posible me gustaria que me puedieras explicar como funcionan esas matrices de coviranza y como poder pasarlo a proton compiler y pic basic.

Muchas gracias
