#Interop LED matrix display with HTTP and REST server ##1. Downloading and installing the libraries This project uses the rpi-rgb-led-matrix library.

Download it, move to the python directory, and build it by following the instructions noted in the README.

##2. Creating the database The interopLCD.py script uses a sqlite3 database to display all the posted texts.

Type the following to create a database.

$ python
>>> from interopLCD import init_db
>>> init_db()

The folder which the database will be created is written in interopLCD.py, so change it to whereever you want it to be.

##3. Starting the script Type sudo python interopLCD.py -b 25 -r 16 -c 2 in order to start the script.

Please refer the arguments from the wledmatrix.py file.

##4. Accessing the REST server The interopLCD.py script also uses Flask to create a REST server.

Test the REST server by typing curl -i -H "Content-Type: application/json" -X POST -d '{"background":"black","text":"Hello World!","color":"white"}' http://<Raspberry Pi IP address>:5000/api/lcd. ##5. Displaying the data from DooR The DooR program sends data via socket communication.

Run python doorpost.py in order to receive data from the DooR program and send that data to the REST server.
