Re: [Paparazzi-devel] Viewing BMP085 messages and fusion with GPS altitude

[Felix Ruess]

Hi,

There is no I2C0 on Lisa/M, use I2C1 or I2C2, see
http://paparazzi.enac.fr/wiki/Lisa/M#Pinout

These sensor modules were only meant as payloads (to log data, etc.).
And currently it's more the proper code that's missing and not
documentation... we should get rid of estimator.c, make a proper baro
interface, etc...
Pull requests always welcome ;-)

Cheers, Felix
