Hi Martin.  Thanks for the reply! Also, thank you for committing the new changes to the ms5611 driver.  I will be in the lab tomorrow to verify that it works.  Thanks again!

Hi,

I'm trying to get the Barometer (MS5611) from the Aspirin 2.1 to work
with Paparazzi 4.2.

What I've tried:
* Adding the module "baro_ms5611_i2c.xml" to my airframe file.
     -- this gave me errors such as 'i2c0' undeclared and 'ground_alt'
undeclared.
* After getting that error I added <define name="I2C0" /> to my airframe
file.
     -- that got rid of the first error but I still get the ground_alt
undeclared error.
* I also tried adding the I2C sub-module but that didn't do anything.

Has anyone been able to get the Aspirin 2.1 onboard barometer to work?
I really don't want to upgrade to the master branch.

The nav.h was missing for ground_alt in the ms5611 driver, added that to v4.2. Also changed the default I2C address to match a low CSB\ as most boards (Aspirin2.1, FreeIMU 0.4.3, ...) have that pin low.

You add i2c0 by having USE_I2C0 in your airframe file.

<target name="ap" board="<your_board_type>">
      <define name="USE_I2C0"/>
      ...

Martin
