PyPRUSS is a Python binding for controlling the PRUs on BeagleBone.
For examples and inspiration: http://hipstercircuits.com/?cat=5
git clone https://[email protected]/intelligentagent/pypruss.git
cd pypruss
python setup.py install
export LD_LIBRARY_PATH=/usr/local/lib
Note that you must load the uio_pruss kernel module. There is a function for loading and unloading this in the library called modprobe() with an optional argument for the DDR size. To do it manually its "modprobe uio_pruss". This must be done on every boot.
Update: It appears there is trouble with the pasm compiler. The following might not work..
cd PyPRUSS/examples/blinkled
make
python blinkled.py
You should then see three of the user leds blink 10 times.
There are a few other examples in there as well, have a look at them for other functions.
