Re: Subject: Re: [Paparazzi-devel] AHRS over SPI on Tiny

[David Conger]

Hi Juan, 

I think your comments are very common. It all seems good with the bench and even walking and orientation testing but the flight is not. The hardware does matter as does the filters and software if you want stable coordinated flight in an unstable airframe. 

The explanation from the guru here has been so valuable to understand why it is easy to make an IMU but difficult to fly with an IMU in a controlled coordinated way. 

I have a good feeling Antoine will soon have something small to  help me with my IMU headaches :)

Hi all,

 

We are currently using the dydrones imu v2 board along with papparazi , The needed Gps data is taken from the tiny and feed into IMU via SPI then the computed angles feed to the tiny by SPI. Currently there is some problems with SPI......

 

The razor is based on the IMUv2 and can run his code with some mods.

 

I have done static and dynamic test (roundabout driving) and the performance is very good..... and I get very good support as one of the developers is local to me.

 

By the way I don´t do any programming ,I´m only the pilot ....
