 +====== Building a libpixyusb Python module on Linux ======
 +
 +
 +====== Introduction ======
 +
 +The 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 update to 1.0.2
 +  * Your system is connected to the internet
 +
 +Instructions for updating the Pixy firmware are here: [[wiki:​v1:​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]%%''​
