#RASPBERRY PI PARALLEL PORT CNC HOW TO#

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

The screens look and operate identical to my Raspberry Pi system. I stayed with Debian based distributions and chose light weight systems such as Sparky Linux or Chrunchbang.

Another advantage is these machines include real serial ports which we can use with python pyserial.

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. (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. There are even modules to allow use of I2C which I won't go into. The advantage over the Raspberry Pi is a more powerful real computer, more I/O, 5-volt TTL level inputs/outputs, real data storage, and greater computing power. These are all at standard TTL 5-volt levels so we don't deal with the 3-volt mess from Raspberry Pi. This includes an 8-bit output data port, five individual input lines and four additional output lines. Using a Python module known as pyparallel we can access the 17 I/O pins on the printer port connector. I've even used it under GW Basic and Borland C++ for DOS.ĭOS is long gone, Windows XP forward is a mess, but Linux is here to stay. This can be tapped into to control external hardware in DOS, Windows, and Linux. The IBM PC has been around close to three decades and most older machines have a printer port. While the Raspberry Pi is the rave for learning Python and interfacing hardware, a much better alternative is sitting in most people's closets. Here we will learn how to use the IBM PC printer port to control external hardware.
