MAPID – Malte's Arduino-Powered Info Display
Info display powered by two parts:
- Command line OS running on Arduino (MAPID/CP)
- Python pyserial script controlling the display over a serial connection
- Arduino libraries
- Python libraries
MAPID is configured using a dotenv file. Currently you have to set three options:
- Serial device file.
- Speed (in Baud) of the serial connection.
9600is the default value of the Arduino Sketch.
- File name for the FIFO. Note that systemd uses a private
/tmpfor services, so the Web-UI cannot access these files, and you have to use a different location.
An example file for GNU/Linux:
# Serial device SERIAL_DEV="/dev/ttyUSB0" # Serial baud rate SERIAL_SPEED=9600 # FIFO filename FIFO="/var/mapid/fifo"
An Arduino sketch containing the command line os MAPID/CP (CP=Control Program). It supports some commands to control a LCD and a LED (there are even a few more non-relevant ones):
- Turn the LED on/off:
- Turn the display on/off:
- Select a line for output:
- Display some text:
ECHO Foo bar
- Clear the display:
A Python library used by the other scripts
Displays a fake bomb countdown like in one of those action movies. Written as a first test for Pyserial communication with MAPID/CP.
A Python script that provides a FIFO file to pass commands to MAPID/CP. Each line read from that file is directly passed over a serial connection.
PHP based Web interface for
fifo_bridge.py supporting all commands of MAPID/CP (except for those without a real purpose, that only return some information relevant for interactive serial connections).
Use the LED and display to show a notification, the purpose of the whole MAPID project.
