MAA - Low Level Skeleton Library for Communication on Intel platforms

Library in C/C++ to interface with Galileo & other Intel platforms over:

• I2C
• SPI
• GPIO
• PWM
• AIO

In a structured and sane API with port nanmes/numbering that match boards & with bindings to javascript & python.

The intent is to make it easier for developers and sensor manufacturers to map their sensors & actuators on top of supported hardware and to allow control of low level communication protocol by high level languages & constructs.

ENV RECOMENDATIONS

All of these are 'optional', however they are recommended. Only a C compiler, cmake and default system libraries are technically required to compile.

1. node.js 0.10.26
2. python 3.3.x or 2.7.x
3. swig-v8 3.0.1 (swig 2.x will work but you will not be able to build node.js module so comment out add_directories(javacsript) in src/CmakeLists.txt)
4. doxygen (needed to generate even python doc)
5. sphinx
6. pygments
7. pydoc

To install swig-v8 the swig-v8-git package from AUR is helpful.

COMPILING

NOTE: The only supported cmake build configuration is to have the build/ dir inside of the repo/tarball.

if swig-v8 is not in your default path you can try run cmake with "-DCMAKE_PREFIX_PATH="/path/to/swig-v8"

mkdir build/ cmake .. make

DEVELOPMENT

Please fork the code on github and then send pull requests. Please avoid merges in your forks. I will also accept patches sent in git style with signoffs to brendan.le.foll@intel.com

USING

see examples/

for node.js make sure that maajs.node is in the current dir and set export NODE_PATH=.

Simple python html documentation can be generated with make pydoc, this does not require the full doxygen/sphinx setup.

API Changelog

When the API breaks in a small way there will be a changelog listed here

0.2.5

• C++/Python/Node Enums/const names now do not contain MAA_GPIO
• Enum type declaration for C++ changed
• Python/Node get_version() -> GetVersion()
• i2c read calls don't use const char* and i2c write calls do

0.2.4

• All maa_ contexts now are pointers to the actual struct which is not delcared in the header. The only end user change is that instead of returning a type maa_gpio_context pointer maa_gpio_init() now returns a maa_gpio_context (which is actually a pointer to struct _gpio internally).
• C++ API is available, use the .hpp headers and add stdc++ to the linker flags.
• Initial SPI implementation is provided

0.2.3

• maa_aio_read_u16() -> maa_aio_read()
• maa_aio_read() now returns a uint16_t instead of an unsigned int

0.2.2

• First version with API considered 'stable'
