PMT Controller Update

I have updated the PIC code for the PMT Controller board. I've uploaded the latest code and also a new version of the spec which reflects the recent changes. You can download these items (and any other MPM documentation) here.


Some highlights from the recent updates...

• The interface between the controller and the PC has been redefined. Now whenever the controller receives any USB command from the PC, it returns a 54-byte array which contains the current status or settings of every controller register.
  
  
• The controller now detects overload errors when a type 3 PMT (Hamamatsu H7422P with cooler and protection circuit) is connected to any of the ports.

• The controller resets the PMT when it detects an error.

• There is an error counter for each channel (which rolls over at 255).
