A PCRE internal error occured. This might be caused by a faulty plugin
====== colour / brightness testing ======
(physical determinants)
{{::colour-test.gif?direct&200|}}
====== 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]]
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 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
