Racket interface library to WiringPi
WiringPi is a Raspberry Pi GPIO access library written in C. It provides an implementation of the Arduino Wiring functions for the Raspberry Pi.
This library provides access to some WiringPi functions using Racket's ffi (foreign function interface). At the moment it only covers those functions which might be used for simple I/O manipulation.
The function names follow the camelCase names used in the C library, rather than more idiomatic Racket names, for ease of familiarity.
