This is a node.js module to use with node-red. It adds read/write nodes to acces bits of the Revolution Pi DIO Module.
It uses the getBit/setBit function of the piTest c-application.
Access via the ffi-module.
A shortended version of the piTest.c is compiled into a shared Library.
Please note, that there is no out of bounds check on the offset value... segmentation faults can be caused easily.
Idea for using ffi comes from this project: https://github.com/tmuellerWieland/revpi
