Sometimes the solution would be easy….
…damn I swapped Rx and Tx and everything went fine,
and I was so sure I connected, documented and even checked multiple times that all is as it should.
At first I thought the level shifter isn’t working, but my brand new Open Workbench Logic Sniffer showed signals, same signals before and after shifting, and was even able to autobaudrate guess my GPS defaults which is 38400.
As I 3D printed a case for the cubieboard I needed to remove the board from the robot anyway so I had the chance to look at the tiny pin headers again, oh and yes I swapped the cables for Rx and Tx there…. damn.
I had to recompile the kernel on the cubieboard again, to enable USB CDC ACM support to be able to migrate the dynamixel servos over from the arduino to a dedicated USB2AX controller.
Meanwhile ROS hydro has it’s own gscam modules released, so I migrated from my own compiled module and also reconfigured the topic remapping.

<node pkg=”gscam” type=”gscam” name=”gscamptz” cwd=”node” respawn=”true”>
<env name=”GSCAM_CONFIG” value=”v4l2src device=/dev/video0 always-copy=false ! video/x-raw-yuv,width=320,height=240,framerate=15/1 ! ffmpegcolorspace”/>
<remap from=”camera/image_raw” to=”/camera/ptz/image_raw” />
<remap from=”camera/camera_info” to=”/camera/ptz/camera_info” />
Just upgraded ROS from groovy to hydro on my Cubieboard ARMHF.
As read on the forums ros-hydro-roslisp fails due to a missing LISP compiler on ARMHF,
so I injected a fake package without this dependancy to get ros-hydro-ros-comm installed.
Building Linux-Sunxi-Kernel 3.4.43 for Cubieboard and setup uboot-Image. Done.
Upgrading from Lubuntu Precise 12.04 to 13.08 Raring on my Cubieboard.
