hpio provides support for writing GPIO programs in Haskell. It includes an embedded DSL for writing platform-independent programs, along with low-level monads and IO functions which provide direct access to each supported platform's native GPIO API.

Currently only the Linux sysfs GPIO filesystem is supported, but support for other Unix GPIO platforms is planned.

For details on usage, see the included tutorial module, or the examples directory in the source distribution.
