In an attempt to get my Raspberry Pi talking to my Arduino I’m exploring various different options. The first was to just use the USB connection, but that was too simple. So, here is how to connect the two using the UART on the GPIO pins of the Raspberry Pi.
To make testing easier I wanted to keep the Arduino’s serial connected via USB to my PC so I can print messages there and read it with the Serial Monitor. This meant using the SoftSerial library to implement a second serial port to talk to the Raspberry Pi. To protect my Raspberry Pi and to convert the 5V of the Arduino to 3.3V the Raspberry Pi needs I used a CD4050.
To show how this works the Arduino is running a small program that reads from the Raspberry Pi’s and copies this to my PC via USB. By default the Raspberry Pi uses the UART in two ways: Console Messages (including bootup messages)A getty so you can login via serial To use this serial port for your own uses you need to disable these two services. Connected to PC. 0.3.1a. A module to control Raspberry Pi GPIO channels Latest Version: 0.5.4 This package provides a class to control the GPIO on a Raspberry Pi. Note that this module is unsuitable for real-time or timing critical applications. This is because you can not predict when Python will be busy garbage collecting. It also runs under the Linux kernel which is not suitable for real time applications - it is multitasking O/S and another process may be given priority over the CPU, causing jitter in your program. If you are after true real-time performance and predictability, buy yourself an Arduino !

The Raspberry Pi has some competition, in the shape of the BeagleBone Black. I thought it might be useful to compare these two boards and highlight their relative advantages. Both boards are Linux-based single board computers about the size of a credit card. You can attach monitors, networks, keyboards and mice to both of them and both of them have GPIO connectors that allow you to attach and control external electronics. This makes them suitable for all sorts of DIY projects, from home automation to robot control. About the Raspberry Pi The Raspberry Pi, managed to create a huge amount of interest around the world, even before its release.
While the project started in the UK as a platform for getting kids to learn to program, the board has been adopted around the world as a platform for hobbyists and educationalists. About the BeagleBone Black Historically, the BeagleBone Boards have been around for a while selling at around the $85 mark. Features Operating System Processor and Memory Price. RaspberryPi @Homelabs » RaspberryPi the Arduino Development Tool. Not really too much to say here. There has been much talk on the forums about using arduino and similar systems to provide additional IO capabilities for the RaspberryPi. So I decided to take things a little further and discover whats needed to use the RaspberryPi itself as a development platform using the Arduino IDE. Following the simple steps below, it is possible to install, and run the arduino IDE, and then re program your USB connected arduino. I’m not going to go into too much detail, but simply provide you with the recipe to replicate my success Firstly log on using the pi user (I did it over ssh).
