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 it's modprobe uio_pruss. This must be done
on every boot.
Also, you need to activate the PRU using:
echo BB-BONE-PRU-01 > /sys/devices/bone_capemgr.8/slots #activate the PRU
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.
