Dear Imed LIMAIEM,
its differ from the processor type.
Currently i have the MPU6000 (spi)  and MPU6050 (i2c  drotek modules  )   in combination with processor (lpc2148)   i2c barometer (bmp085) and magnetometer running for the LPC2148 for fixed wing and multirotor (MPU6000 spi). It is difficult to hold the 500 Hz for multirotor with the MPU6050.
The base for the MPU6000 driver is the aspirin driver with a new spi interfasce for the spi  interface of the  lpc2148.
For fixed wing (60Hz) the driver aspirin2_i2c works fine with drotek modules.
I will send a push request soon.
It would be nice if we split the asperin driver in 2 parts. One for imu data  and a secound for additonal  i2c  sensors magnetometer and  barometer.

Hi all,

I have one simple question.

I see lot of IMU in the market with many combination of sensors (MPU60XX, Barometers ... Magnetometers ...) and many drivers been written for each sensor and each AP architecture with the following combinations:


My question is: Is PPZ code able to recognize each combination ? I mean if I plug an IMU in the I2C port and define well this my airframe code will it work ? or should I modify the drives and so ... ?
