  • C++ program
  • Single USB provides power, programming and control.
  • Solder-less construction.

Supported commands

  • ? - Help
  • T - Set time
    • Notation: HH:MM:SS or HH,MM,SS
    • HH can be either 12 or 24 hour notation. e.g. '03:00:00' is the same as '15:00:00'
    • Delimiter can be either ':' or ','. e.g. '15:00:00' is the same as '15,00,00'
    • MM is in the range 0<=MM<=59
    • SS is in the range 0<=SS<=59
    • Leading zeros can be omitted. e.g. '1:2:3' is the same as '01:02:03'
    • Trailing parameters can be omitted. e.g. '12:15' is the same as '12:15:00'
  • L - Set level
    • Notation: 2 digit percentage 0<=NN<=100
  • V - Version info
  • X - Invert X axis
  • Y - Invert Y axis

Limitations:

  • USB serial requires Windows (10 or later)
