Our docs are ahead of our release in debs (this will be fixed very shortly). In 0.1.0, this message was in the rosserial_arduino_demo package.

You can certainly do a:

rosrun rosserial_arduino <sketchbook> rosserial_arduino_demo

But I would really recommend you upgrade to the latest (soon to be 0.2.0) code by doing a source checkout:

cd <some directory on your ROS_PACKAGE_PATH>
hg clone
rosmake rosserial

Hi, first solution works out of the box ! I try source checkout after some more tests with current version.

BTW: For stress tests of the Arduino, I've added more functionality into the code...

Now, I have some questions about ADC handling. To use TWI/I2C for magnetic compass and 3D-accelerator sensors, I cannot use all ADC-channels. Currently the sources for ADC are hardcoded for all 6 channels, but where should I change it to use 4 channels only ? Do I have to modify Adc.h ?

Thanks for some ideas Cheers Christian

You could change the ADC message, but I would suggest instead defining either your own message type, or just not filling in the last 2 fields of the message. Either way, you will want to publish the compass/etc data as a new topic.
