Hi,
The Quadrocopter speed of  rate sensors signals has to be larger than accelerator signals.
If backstepping is used , a  10ms rate  work for the point of stabilization.
Since the accelerator signals are only  used for bias correction  a rate of 20 to 50ms is working well.
The point is that the estimation of the angle can be done much slower than the basic stabilization without any problems.
Regards
Heinrich

Hi Christophe,

I'm still buying the BOM. Slow process. I have the LPC and other large parts. 

I'm curious. How did the flying with PPZIMU Go? Last I remember you said you were test flying last week I believe. I'm wondering what I can expect.

The YAI imu is software compatible with the Booz-imu (just need a different calibration). Please note that while the gyro's are relatively easy to solder, the accelerometer and magnetometer are not that simple with there pads not sticking out the sides.

The aspirin-imu at this moment only has a simple 100Hz driver for the LPC processor (on booz), good enough for fixedwing (way faster than thermopiles) but for quadrotors you probably want to improve the driver first.

Hi all,

I'm trying to make the paparazzi hardware. I have soldered the main and the GPS boards. I have soldered the IMU board too but I think I's going to fail due to the difficulty to solder Gyros and acceloremeters.
I would like to use another IMU. I'm thinking to buy Aspirin IMU or to make YAI IMU. Do they work with BOOZ? Has anyone try them?

Thanks in advance

 Regards,

Rafael Espino.
