MRAA

Low Level Skeleton Library for IO Communication on GNU/Linux platforms

C/C++ library with bindings to JavaScript and Python to interface with the I/O on the Intel® Galileo board, Intel® Edison board, and other platforms. With board detection done at runtime, you can create portable code that works across multiple platforms.

• AIO Sensors requiring an ADC value to be read

• I2C Modules using the i2c bus

• SPI Modules using the SPI bus

• GPIO Modules using GPIOs directly

• PWM Modules using a PWM capable GPIO pin

• UART Modules using a serial connection (RX/TX)
