MpDuino

A small project to interface an Arduino Uno with an OLED display, rotary encoder to a MPD server.

Idea is to have one script mpduino.py creating multiple processes to which one can attach

From PySerial to Arduino

A command looks like [ES][VTAarzxcusP].*. Where S stands for set and E is to echo a value. The [VTAarzxcusP] part selects what to set or echo. You can use S!.* to echo a message back.

Character	Property	.*
V	Volume	number
T	Title	text
A	Artist	text
a	album	text
P	Playing	empty(false)/text(true)
r	repeat	empty(false)/text(true)
z	shuffle	empty(false)/text(true)
x	random	empty(false)/text(true)
c	consume	empty(false)/text(true)
u	updating	empty(false)/text(true)
s	single	empty(false)/text(true)

From Arduino to PySerial instance

Since the Arduino has a rotary encoder for the volume and play/pause, we need to pass these through. Next tot this, we might reset the arduino, without resetting the pySerial script, so we need to set all values again.

R	Reset
V	Volume
P	Pause/Play
t	Temperature
h	Humidity
