pymedioex

A Python extension for using MedIOEx card properly.

Installation

First of all, be sure you have python3-dev and build-essential packages installed. If they're not, install them first by typing:

sudo apt-get install python3-dev build-essential

That's all for dependencies.

Here are the steps of installation:

• Be sure you have bcm2835 library installed. Here is the install link.

  Steps to install bcm2835:

  pi@raspberrypi:~ $ sudo su
  root@raspberrypi:/home/pi# tar zxvf bcm2835-1.50.tar.gz
  root@raspberrypi:/home/pi# cd bcm2835-1.50
  root@raspberrypi:/home/pi/bcm2835-1.50# ./configure
  root@raspberrypi:/home/pi/bcm2835-1.50# make
  root@raspberrypi:/home/pi/bcm2835-1.50# make check
  root@raspberrypi:/home/pi/bcm2835-1.50# make install
  

  This will install the C dependencies for bcm2835.

• Download a proper release

• Unzip it.

• Go to library directory and open a terminal

• Check your python version to use

• Open a terminal and write sudo python3 setup.py install

Then you can open a shell and use library like this (Note that you might need to be superuser before opening the shell.)

>>> import medioex
>>> medioex.do_di_init()  # Need for using Digital Inputs/Digital Outputs initialization
>>> medioex.do_write(3, 1)  # Sets Digital Output 3 HIGH
>>> a = medioex.di_read(5)  # Reads from Digital Input 5
>>> medioex.do_write(13, 1)  # Sets Relay Output 13 HIGH
>>> medioex.ai_init()  # Need for reading from Analog Inputs initialization
>>> b = medioex.ai_read(4)  # Reads from Analog Input 4
>>> mediex.ao_init()  # Need for writing to Analog Inputs initialization
>>> medioex.ao_write(3, 4095)  # Writes 4095 to Analog Output 3

Notes

If you want to read analog inputs continuously, please put a sleeping time >= 0.2s
