1 MAA - Low Level Skeleton Library for Communication on Intel platforms
4 Library in C/C++ to interface with Galileo & other Intel platforms, in a
5 structured and sane API with port nanmes/numbering that match boards & with
6 bindings to javascript & python.
8 The intent is to make it easier for developers and sensor manufacturers to map
9 their sensors & actuators on top of supported hardware and to allow control of
10 low level communication protocol by high level languages & constructs.
14 These interfaces allow you to interact with all libmaa functionality. The C++
15 classes directly wrap the C API and provide a near 1:1 mapping of

47 ## Supported platforms
51 ### ENV RECOMENDATIONS
53 All of these are 'optional', however they are recommended. Only a C compiler,
54 cmake, libm and pthreads are technically required to compile.
56 - Swig 3.0.1+ built with node.js & python support (0.10.x)
58 - sphinx (requires doxygen)
69 Please fork the code on github and then send pull requests. Please avoid merges
70 in your forks. I will also accept patches sent in git style with signoffs to
71 brendan.le.foll@intel.com
75 When the API breaks in a small way there will be a changelog listed here
78 * C++ API now uses basic types and not unistd types as C
79 * Clearer and consistent use of unistd tpyes in C api
82 * C++ examples added, using c++ headers/api.
83 * moved to open instead of fopen in all modules
84 * rename maa_check functions and made them internal to maa only.
85 * removed "export" functions from api
86 * Intel Galileo Gen 1 (rev d) fixes, incorrect definition of some items
87 * SPI, implementation completed.
88 * I2C internal function, completed.
89 * PWM fix bug in period set method.
90 * Swig upstream can be used for building.
91 * No longer builds docs on default cmake, needs flag
92 * GPIO/PWM ownership guard prevents closing on existing pins, still can be forced.
95 * C++/Python/Node Enums/const names now do not contain MAA_GPIO
96 * Enum type declaration for C++ changed
97 * Python/Node get_version() -> GetVersion()
98 * i2c read calls don't use const char* and i2c write calls do
101 * All maa_ contexts now are pointers to the actual struct which is not
102 delcared in the header. The only end user change is that instead of
103 returning a type maa_gpio_context pointer maa_gpio_init() now returns a
104 maa_gpio_context (which is actually a pointer to struct _gpio internally).
105 * C++ API is available, use the .hpp headers and add stdc++ to the linker
107 * Initial SPI implementation is provided
110 * maa_aio_read_u16() -> maa_aio_read()
111 * maa_aio_read() now returns a uint16_t instead of an unsigned int
114 * First version with API considered 'stable'
