Virtual COM Port

The OSVR unit provides a com port on the USB interface. Commands begin with # and are terminated with \n. All command parsing is performed in SerialStateMachine.c Parsing functions generally work on one character, then pass control to a sub-parser.

Command Set

Commands can be given in upper or lower case. For the descriptions below, however, I've used upper case for the literal command and lower case to denote parameters of commands.

Parameters

  • n - single numeric digit
  • aa - two character hex address
  • xx, yy, zz, ww - two character hex value.
