Python parallel port windows

While the Raspberry Pi is the rave for learning Python and interfacing hardware, a much better alternative is sitting in most people's closets. This includes an 8-bit output data port, five individual input lines and four additional output lines.

There are even modules to allow use of I2C which I won't go into. Above Here in this series we will learn how to read an external analog voltage and operate a LCD display by using python's bitwise operators.

In using an older PC or even a new one I employ the very same fast desktop system I created for the Raspberry Pi and the setup of the system is nearly identical. Another advantage is these machines include real serial ports which we can use with python pyserial. I stayed with Debian based distributions and chose light weight systems such as Sparky Linux or Chrunchbang. The screens look and operate identical to my Raspberry Pi system.

In fact the Python programs I wrote for this with modifications will work on Raspberry Pi as far as the hardware interface. I design my programs to work across multiple platforms with minimal use of special libraries. I'll assume the user has some knowledge of Linux but I'll walk the process through step by step.

Read how to setup Raspberry Pi on my website for more information on Linux. It worked a little better than Raspberry Pi. I chose this obsolete machine to demonstrate how to reuse an older computer.

Update August a Linux live DVD is now available to allow one to experiment and use the programs presented here without installation to one's computer. If it isn't there then "sudo modprobe ppdev". This is default with most 2. The Parallel class described below will attempt to load whichever parallel port driver is first found on your system and should suffice in most instances. If you need to use a specific driver then, instead of using ParallelPort shown below you can use one of the following as drop-in replacements, forcing the use of a specific driver:.

There is also a legacy API which consists of the routines which are directly in this module. PP-Speaker is a linux kernel alsa driver parallel port audio, covox. If you construct one and flash it with the software here, this device should serve your realtime audio presentation needs sync'd with an EEG amp, especially if you're very concerned with jitter. To be compiled in mex. Device driver for small keyboards connected to the parallel port.
