HPi
Library to access the GPIO pins on a Raspberry Pi from Haskell. Works with all Raspberry Pi versions up to and including v4.
===
HPi is a small library to access the GPIO pins on a Raspberry Pi from Haskell. It also includes some functions to use the I2C and SPI functionality of the Raspberry Pi, see the haddock documentation for details. It is constructed as a FFI wrapper around the bcm2835 library, which is written in C. Because this library accesses the GPIO pins directly via a memory map, it should be faster than libraries which access the GPIO pins via the /sys/class/gpio interface.
===
In order to compile programs including this library, you will need to have the bcm2835 library installed. It can be found at http://airspayce.com/mikem/bcm2835/index.html. When performing the cabal install for HPi you may need to pass the --extra-lib-dirs and --extra-include-dirs flags if you have installed bcm2835 at a non-standard path. This library has been tested to work with bcm2835 version 1.63. Note that you cannot access the memory map without root privileges, programs should be run with sudo.
