A Raspberry Pi GPIO library for newLISP
This library is pretty self explanitory, use the source, Luke!
Include the library at the top of your script with:
(load "raspi-gpio.lsp")
From there on, use it similarly to how you'd use Arduino/Wiring, with the exception that it's wrapped up inside the GPIO context:
(GPIO:enable-pin 4)
(GPIO:pin-mode 4 GPIO:out)
(GPIO:digital-write 4 GPIO:high)
(GPIO:disable-pin 4)
