Write nodes for PI [closed]
Hi,
I have hydro installed on a RPI. I'm trying to get my feet wet with this setup bu controlling a servo. I haven't been able to find any types of tutorials online for such a task. I know how to do this with an arduino, but I want to do this with the servo plugged into the PI directly. All I have done in the past is run rosserial at a specific usb port, then publish an angle to that. So, I think I need direction in two things. Control a servo without an arduino, and publish to a servo connected with pins and not a usb.
For interfacing with RPi pins to a servo I suggest you ask on a RPi forum. That's not a ROS question. Once you have a program to interface with the pins you just need to bring in a ROS client library like any other process to interact on the ROS network.
