-====== Using the Python API on Linux ======
-====== Introduction ======
-Pixy now has a Python wrapper for libpixyusb. For now, this is only available for Linux-based controllers (e.g. Raspberry Pi, BeagleBone). The [[wiki:Building_the_libpixyusb_example_on_Linux|libpixyusb]] library provides a software application programming interface (API) for communicating with Pixy over USB. The following procedure will outline the steps to build libpixyusb as a Python module.
-This procedure assumes the following:
-  * Your system is Linux (with Debian package manager)
-  * Pixy firmware has been updated to 1.0.2 or higher
-  * Your system is connected to the internet (for getting packages)
-Instructions for updating the Pixy firmware are here: [[wiki:Uploading_New_Firmware|Uploading New Firmware]]
-====== 2. Procedure ======
-===== 2.1. Install dependencies for building Python SWIG module =====
-Start a terminal application.
-==== 2.1.1. Install SWIG ====
-In a terminal window type:
-''%%# sudo apt-get install swig%%''
-==== 2.1.2. Install libusb-1.0-0-dev ====
-In the terminal window type:
-''%%sudo apt-get install libusb-1.0-0-dev%%''
-==== 2.1.3. Install g++ (compiler) ====
-In the terminal window type:
-''%%sudo apt-get install g++%%''
-==== 2.1.4. Install libboost ====
-In the terminal window type:
-''%%sudo apt-get install libboost-all-dev%%''
-===== 2.2. Build the libpixyusb Python module =====
-==== 2.2.1 Download Pixy source code ====
-In the terminal window type:
-''%%git clone https://github.com/charmedlabs/pixy.git%%''
-==== 2.2.2. Build the Python module ====
-In the terminal window type:
-''%%cd pixy/scripts%%''\\
-''%%./build_libpixyusb_swig.sh%%''
-===== 2.3. Try it out! =====
-Make sure your Pixy is connected to a USB port on your computer. Then in the terminal window type:
-''%%cd ../build/libpixyusb_swig%%''\\
-''%%python get_blocks.py%%''
-If all goes well, you should see blocks:
-''%%Pixy Python SWIG Example -- Get Blocks%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=220 Y= 17 WIDTH= 43 HEIGHT= 35]%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=220 Y= 23 WIDTH= 42 HEIGHT= 47]%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=220 Y= 23 WIDTH= 42 HEIGHT= 47]%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=220 Y= 23 WIDTH= 42 HEIGHT= 47]%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=220 Y= 23 WIDTH= 42 HEIGHT= 46]%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=220 Y= 23 WIDTH= 45 HEIGHT= 46]%%''\\
-''%%[BLOCK_TYPE=0 SIG=1 X=219 Y= 23 WIDTH= 43 HEIGHT= 46]%%''
-If you don't see any block information, try running as superuser:
-''%%sudo python get_blocks.py%%''
