+ | ====== 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:v2: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]%%'' | ||
