CHAPTER 2

INTRODUCTION TO ARDUINO/PINGUINO/MAPLE

2. What is Arduino?

Arduino is an open-source electronics prototyping platform, designed to make the process of using electronics in multidisciplinary projects easily accessible. The hardware consists of a simple open hardware design for the Arduino board with an Atmel AVR processor and on-board I/O support. The software consists of a standard programming language and the boot loader that runs on the board.

Arduino hardware is programmed using a Wiring-based language (syntax + libraries), similar to C+ + with some simplifications and modifications, and a Processing-based Integrated Development Environment (IDE).

The project began in Ivrea, Italy in 2005 aiming to make a device for controlling student-built interaction design projects less expensively than other prototyping systems available at the time. As of February 2010 more than 120,000 Arduino boards had been shipped. Founders Massimo Banzi and David Cuartielles named the project after a local bar named Arduino. The name is an Italian masculine first name, meaning "strong friend". The English pronunciation is "Hardwin", a namesake of Arduino of Ivrea.

More information could be found at the creators web page http://arduino.cc/ and in the Arduino Wiki http://en.wikipedia.org/wiki/Arduino

To make the story short - Arduino is easy for beginners who lack Electronics knowledge, but also does not restrict professionals as they can program it in C++ or mix of Arduino/C++ language.

There are thousands of projects which makes it easy to startup as there is barely no field where Arduino enthusiasts to have not been already.

Arduino has inspired two other major derivates - MAPLE and PINGUINO. Based on 8-bit AVR technology the computational power of Arduino boards is modest, this is why a team from MIT developed the MAPLE project which is based on ARM7 STM32F103RBT6 microcontroller. The board have same friendly IDE as Arduino and offers the same capabilities as hardware and software but runs the Arduino code much faster. The Maple project can be found at http://leaflabs.com

In parallel with Arduino another project was started called PINGUINO. This project chose its first implementation to be with PIC microcontrollers, as AVRs were hard to find in some parts of the world like South America so it is likely to see lot of PINGUINO developers are from that part of the

world. PINGUINO project founders decided to go with Python instead Java for processing language. For the moment PINGUINO is much more flexible than Arduino as it is not limited to 8bit microcontrollers. Currently the IDE, which has GCC in background, can support 8-bit PIC microcontrollers, 32bit PIC32 (MIPS) microcontrollers and ARM7/CORTEXM3 microcontrollers which makes PINGUINO very flexible because once you make your project you can migrate easily through different hardware platforms and not being bound to a single microcontroller manufacturer. The PINGUINO project can be found at: http://www.pinguino.cc.

2.1 First steps with Pinguino IDE

Download the latest Pinguino IDE distribution depending on your operation system and install it. Connect your device in bootloader mode to the computer (for PIC32-PINGUINO-MX220 hold BUT and press RST after connected). Start the IDE from it's shortcut. From Preferences choose board (for PIC32-PINGUINO-MX220 that would be PIC32-Pinguino_220). From File->Open navigate to the examples folder which is found in the Pingino IDE installation folder. Choose a simple example to begin with like BlinkWithoutDelay.pde and open it. Click “Compile” (blue arrow) and after it compiles click “Upload to Pinguino” (green arrow). Voila, you have uploaded code to your Pinguino device.

Now start exploring the world of Pinguino! More info and help on the software can be found and the official pinguino web site. You can leave your feedback on the project and report bugs at the forum: http://forum.pinguino.cc/.
