If you are a fan of the Raspberry Pi mini computer, then you probably know that the company released their updated Model B+ last month. This newest model has the same processor and RAM, and runs on the same operating system. However, the team at the Raspberry Pi Foundation was able to integrate several updates that had been requested by users of the Model B. To meet the needs of their customers, the company built in more GPIO, two additional USB ports (for a total of four), a micro SD slot, improved the audio output, and were able to reduce the power consumption of the unit. They did all this and managed to keep the price at a reasonable $35 per unit. Of course, an updated mini computer means you’ll be needing an updated Raspberry Pi enclosure, too!

In this article I will discuss popular operating systems for the Raspberry Pi. All of these systems are open source and free to use. A few of them are designed for more specific purposes, and may not be necessarily well suited for industrial applications. The majority of operating systems on this list are more generic desktop systems that can be adapted to run as an industrial control system. I will explain how you can utilize these OS’s in such a manner in each of their respective sections.

Raspberry Pi Camera Module Software

In my last article I discussed the Raspberry Pi Foundation’s Camera Module, but focused mainly on its hardware. In this article I am going to discuss the software that utilizes the hardware. The main ways to use the module is with raspistill and raspivid, which are Linux commands. They are used to record a still image or video in the Raspbian operating system. These Linux commands can also be called from a C program, and I’ll cover more on this later. You can also utilize the camera module using a Python library called picamera. Pyhton is a very easy to learn high-level language. It is much less like C and is more comparable to Java.
