We have pushed a more completed set of initialization parameters to the OLED display and also have a battery voltage now showing up if the ROS system has a /battery_state topic like our robot has.
While looking at this I also ran across one display that came up in an odd state even on my tried and true test rig for these displays. So I now will have to watch for quality control on these displays and get a test going in production so at least at the factory we have validated the display is good. We do not have an image that supports the display yet so we must have that then implement the production test.
