JAKE Drivers

This project contains drivers for the JAKE sensor packs. For more information on the devices and their capabilities, see the wiki.

This repo contains multiple drivers. The most feature complete implementation is a C++ driver that can be compiled for Windows, OSX and Linux (32/64-bit). This driver also has bindings for Python, C# and Java, although in some cases functionality supported by the C++ code has not yet been exposed through these bindings.

In addition, there are two separate implementations, one written in Python (with a dependency on pyserial) and one written in Java (probably most useful in that it supports Android).

NOTE: If you install both the Python/C++ bindings and the pure Python implementation in the same Python environment you may encounter naming conflicts, as both include a module called "pyjake".

Installation on Windows

The easiest way to get up and running quickly on Windows is to use the Python implementation. Install pyserial, then run python setup.py install from the jake-drivers/python directory.

If you want to use the C++ driver, you'll need to compile it first. Inside the jake-drivers/cpp directory, you'll find:

• jake_driver (the C++ code)
• pyjake (Python bindings for jake_driver)
• jake_cs (C# bindings for jake_driver)
• jake_java (Java bindings for jake_driver)
• jake_mex (Basic Matlab bindings for jake_driver)

Each of these should have a Visual Studio project file that can be used to compile them individually depending on which parts you need. They will probably also compile with gcc/g++ from MingW, but there are no build scripts for this at the moment.

Installation on OSX

Again the Python implementation is the easiest way to get started quickly:

• Install pyserial
• Run python setup.py install from jake-drivers/python

If you have the XCode/developer packages installed and want to compile the C++/Python bindings:

• Run sh build_osx_64.sh from jake-drivers/cpp/jake_driver
• Run python setup_osx.py install from jake-drivers/cpp/pyjake

Installation on Linux

Similar to OSX. For the Python implementation:

• Install pyserial
• Run python setup.py install from jake-drivers/python

For the C++/Python bindings:

• Run sh build.sh from jake-drivers/cpp/jake_driver
• Run python setup.py install from jake-drivers/cpp/pyjake

A basic example

(for more examples see the wiki page

Python / pyserial

from pyjake import *
jd = jake_device()

# connection details depend on platform
# Windows (virtual COM port number)
device = 10
# OSX (Serial Port Profile dev node)
# device = '/dev/tty.JAKESN0077-SPP'

jd.connect(device) # returns False if connection failed
print jd.acc() # current accelerometer output
print jd.mag() # current magnetometer output
print jd.heading() # current heading output
jd.close()

Python/C++ bindings

from jake import *
jd = jake_device()

# Windows: for non-Microsoft Bluetooth stacks
jd.connect(10) 

# Windows: if you're using the Microsoft Bluetooth stack, 
# you can instead connect by specifying the device address directly
jd.connect_rfcomm('aa:bb:cc:dd:ee:ff')

# OSX: always use this function
# TODO

# Linux: Bluetooth device address
jd.connect_rfcomm('aa:bb:cc:dd:ee:ff')

# access data...
print jd.acc(), jd.mag(), jd.heading()

jd.close()
