Documentation and code for interfacing with SBB split flap display modules.

General

Most documentation in this repository is taken from old original documents or reverse engineered. It is far from being complete. If you have any additional information which you'd like to share, please contact us or even create a pull request.

Documentation

There are 2 types of single modules in this repo called old and new ones. The old ones do not have an integrated RS485 controller while the new ones do.

For complete units there only seems to exist an "Omega controller" which appears to to talk to old modules only.

Components

Panel Simulator

The panel_mock.py script can be used to simulate an alphanumerical panel with variable width.

Setup:

>>> from sbb_fallblatt import sbb_rs485, panel_mock
>>> from multiprocessing import Process
>>> mock_panel = panel_mock.MockPanel(10, 21)
>>> mockthread = Process(target=mock_panel.run)
>>> panel_control = sbb_rs485.PanelAlphanumControl(addresses=list(range(10,21)), port=mock_panel.get_serial_port())
>>> panel_control.connect()
>>> mockthread.start()
>>> panel_control.set_text("test01")
>>> panel_control.get_text()
'test01     '
>>> panel_control.get_serial_number(10)
b'\x01\x88?\x00'
>>> mock_panel.stop()
>>> mockthread.kill()
>>> mockthread.join()

Clock

>>> import time
>>> from datetime import datetime
>>> from multiprocessing import Process
>>> from sbb_fallblatt import sbb_rs485, panel_mock
>>>
>>> mock_panel = panel_mock.MockPanel(10, 12)
>>> mockthread = Process(target=mock_panel.run)
>>> mockthread.start()
>>>
>>> clock = sbb_rs485.PanelClockControl(addr_hour=10, addr_min=11, port=mock_panel.get_serial_port())
>>> clock.connect()

>>> clock.set_time(15, 35) # or use clock.set_time_now()
>>>
>>> clock.get_hour()
15
>>> clock.get_minute()
35
>>> clock.set_time(22, 9)
>>> clock.get_time()
(22, 9)
>>>
>>> mock_panel.stop()
>>> mockthread.kill()
>>> mockthread.join()
