WARNING This module has been deprecated in favor of Raspi.js. Raspi.js uses a more advanced mechanism for managing peripherals, and is considerably more performant. Bugs will not be fixed in this module. The raspi-llio (Low Level Input/Output) module exposes the Wiring Pi C library to Node.js, which provides access to GPIO, PWM, I2C, SPI, and UART capabilities. For more in depth information on how raspi-llio works, visit the Wiring Pi docs. All methods in this library map directly to a Wiring Pi method. Many of the methods are wrapped up in an object that must first be instantiated and handles file descriptors transparently.
