BackMain Prototype Final Objectives
Done
- USB[0,1,2,3,4,5] out from each computer. There are a few that does not work. It's listed on the top of the main electrical section.
- KVM power
- KVM USB - propeller control
- KVM VGA - propeller control
BackMain Prototype Final Results
No catastrophic error.
Bug List
- USB hub board hits the USB8 adapter board. Fixed by placing it below the back main board
- USB common signal for D+ and D- is flipped. We twist the ribbon cable that goes into it. The permanent solution should be changing the library part of the hub.
