Here is a simple example for controlling a Betabrite Prism via USB::

  import time
  import alphasign


  def main():
    sign = alphasign.USB(alphasign.devices.USB_BETABRITE_PRISM)
    sign.connect()
    sign.clear_memory()

    # create logical objects to work with
    counter_str = alphasign.String(size=14, label="1")
    counter_txt = alphasign.Text("counter value: %s%s" % (alphasign.colors.RED,
                                                          counter_str.call()),
                                 label="A",
                                 mode=alphasign.modes.HOLD)

    # allocate memory for these objects on the sign
    sign.allocate((counter_str, counter_txt))

    # tell sign to only display the counter text
    sign.set_run_sequence((counter_txt,))

    # write objects
    for obj in (counter_str, counter_txt):
      sign.write(obj)

    # (strictly) monotonically increasing counter
    counter_value = 0
    while True:
      counter_str.data = counter_value
      sign.write(counter_str)
      counter_value += 1
      time.sleep(1)
