Bare Conductive Pi Cap OSC Data Stream Utility

Example OSC data streaming code for the Bare Conductive Pi Cap. Streams touch and proximity data from the Pi Cap to a network target (default is 127.0.0.1) via OSC on a specified port (default is 3000). The target can be an IPv4 address or a hostname - but not an IPv6 address at this time. Can optionally interface with Bare Conductive's MPR121 grapher.

Requirements

• Requires python-dev (apt-get install python-dev)
• Requires WiringPi (apt-get install wiringpi)
• Requires Bare Conductive's MPR121 libary for WiringPi
• Requires python-liblo (apt-get install python-liblo)

Install / Build

• You should install this code as part of the Pi Cap Raspbian package: sudo apt-get install picap
• However, if you are doing this yourself, clone the repository and follow the usage instructions.

Usage

Sends Pi Cap readings through OSC - MUST be run as root.

Usage: python datastream-osc.py [OPTION]

Options:
  -h, --host   host address, defaults to 127.0.0.1
  -p, --port   port on which to send, defaults to 3000
      --help   displays this message
