A set of python scripts to display near real-time RATP Metro station departure data on SSD1322-based 256x64 SPI OLED screens. Uses the open-source Unofficial RATP API. This project has been developed and simplified based on the work of others.
Just clone this repository, then copy it to a RaspberryPi using SSH or any other means. Tested with RaspberryPi Zero W.
Placing yourself in the root of the repository:
cp config.sample.json config.json- Fill the
config.jsonfile with the following variables:
| Key | Example Value |
|---|---|
name |
La Defense (examples) display name of the departure station |
slug |
la+defense (examples) url slug for API call to unofficial API |
line |
1 (examples) metro line code in unofficial API |
direction |
R (examples) direction of train ("A" or "R") in unofficial API |
refreshTime |
120 seconds between data refresh |
This project (without modification) requires the use of a SSD1322-based 256x64 SPI display, an OLED in yellow for the authentic look. I have used a display from AliExpress successfully.
The connections for the display to the Raspberry Pi GPIO header are as follows, but it would be a good idea to check the connections with the datasheet of your particilar display before powering on as there's no guarantee yours will match the pinout of mine.
| Display | Connection | Raspberry Pi |
|---|---|---|
| 1 | Ground | 6 (Ground) |
| 2 | V+ (3.3V) | 1 (3v3 Power) |
| 4 | D0/SCLK |
23 (BCM11 SCLK) |
| 5 | D1/SDIN |
19 (BCM10 MOSI) |
| 14 | DC (data/command select) |
18 (BCM24) |
| 15 | RST (reset) |
22 (BCM25) |
| 16 | CS (chip select) |
24 (BCM8 CE0) |
NB: In order to use the display with the 4-wire SPI protocol, you need to desolder the R6 shunt resistor and solder it on the R5 pads as indicated on the data table on the back of the OLED screen PCB
There are .stl 3D models for a case available in the assets directory.
A big thanks to Chris Hutchinson who originally started this project and inspired me to develop it further. Blake made some further improvements and this project was forked from there.
The fonts used were painstakingly put together by DanielHartUK and can be found on GitHub at https://github.com/DanielHartUK/Dot-Matrix-Typeface - A huge thanks for making that resource available!
