Re: [Paparazzi-devel] aspirin2.1 I2C jumper configuration

[Piotr Esden-Tempski]

Hi Martin,

Sorry about the delayed answer.

It depends on what you want to accomplish.

The magnetometer is connected to the slave i2c interface of the MPU-6000 and 
the current aspirin 2.1 drivers are reading out the magnetometer using the MPU.

The jumpers make a connection between the STM32 i2c interface and the devices 
connected "behind" the MPU-6000. In the case when you really want the STM32 
rather then the MPU-6000 to directly talk to the magnetometer you have to 
remove R1 and R2 and connect J4 and J5.

I will try to update the documentation of Aspirin in the wiki to better explain 
the situation bit better.

Cheers Piotr
