Libmraa is a C/C++ library with bindings to Python, Javascript and Java to interface with the I/O on Galileo, Edison & other platforms, with a structured and sane API where port names/numbering matches the board that you are on. Use of libmraa does not tie you to specific hardware with board detection done at runtime you can create portable code that will work across the supported platforms.

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.

API

These interfaces allow you to interact with all libmraa functionality. The C++ classes directly wrap the C API and provide a near 1:1 mapping of functionality.

C API Modules	C++ API Classes
gpio	Gpio class
led	Led class
i2c	I2c class
aio	Aio class
pwm	Pwm class
spi	Spi class
uart	Uart class
common	common

Hello Mraa

#include "mraa.h"
int
main(int argc, char** argv)
{
    const char* board_name = mraa_get_platform_name();
    fprintf(stdout, "hello mraa\n Version: %s\n Running on %s\n", mraa_get_version(), board_name);
    mraa_deinit();
    return MRAA_SUCCESS;
}

Supported platforms

DEBUGGING

Sometimes it just doesn't want to work, let us try and help you, you can file issues in github or join us in mraa on freenode IRC, hang around for a little while because we're not necessarily on 24/7, but we'll get back to you! Have a glance at our Debugging libmraa page too

COMPILING

More information on compiling is Building libmraa page.
