smioplus 1.0.6

Library to control Sequent Microsystems ioplus Card

libioplus

This is the python library to control the Home Automation Stackable Card for Raspberry Pi.

Install

sudo pip install SMioplus

Usage

Now you can import the megaio library and use its functions. To test, read relays status from the board with stack level 0:
