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.


Logs

Soldered the components unto the boards. USB hub has to be soldered below the board instead because of conflict.


Friday, May 8, 2009 USB Hub can use 100mil pitch (instead of the 2mm pitch)
