====== arduino+python ======

(software determinants)

set up the SD card: http://arduino.cc/en/Tutorial/ExpandingYunDiskSpace (needs an Internet connection; set it up [[http://arduino.cc/en/Guide/ArduinoYun#toc13|like this]]

arduino >> python

upload an [[arduino-call-python|arduino sketch]] which calls a [[python-osc-arduino|python script]] using Process from the Bridge library

**! must open the Serial Monitor for the script to actually run !!!**

python >> arduino

[[bridgeclient.py]]
===== python OSC =====

install it the regular way:

<code>
opkg update #updates the available packages list
opkg install distribute #it contains the easy_install command line tool
opkg install python-openssl #adds ssl support to python
easy_install pip #installs pip
pip install python-osc #installs the osc module https://pypi.python.org/pypi/python-osc/1.4.1
</code>
not the module i wanted :(

install this module instead https://trac.v2.nl/wiki/pyOSC

<code>
### download the module from https://trac.v2.nl/raw-attachment/wiki/pyOSC/pyOSC-0.3.5b-5294.tar.gz
### untar, cd into the directory
### run
./setup.py install
</code>

works

===== problems =====
