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.

### New Modules

* [Electrical details](./doc/electrical_new_module.md)

* [Communication protocol](./doc/protocol_new_modules.md)

* [Char<->Blade mapping](./doc/char_mapping.md)

### Old Modules

* [Electrical details](./doc_omega_module/electrical_omega_module.md)

* [Char<->Blade mapping](./doc_omega_module/char_mapping.md)

### Omega Controller

* [Electrical details](./doc/electrical_omega_controller.md)

* [Communication protocol](./doc/protocol_omega_controller.md)

## Components

### Panel Simulator

The `panel_mock.py` script can be used to simulate an alphanumerical panel

with variable width.

Setup:

```python

>>> 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

```python

>>> 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()

```
