It looks like when the Blue comes out of the box, running a current image it's all set up to run the Robotics stuff. You can access the ADCs, servos, etc. through the robot interface.
When I teach my Embedded Linux class I would also like my students to access the ADCs, PWM, etc in the Linux way. *How do I configure the Blue to boot up in "Embedded Linux" mode rather than "Robot Linux" mode*? --Mark On Wednesday, August 2, 2017 at 11:15:40 AM UTC-4, Mark A.
