OLIMEX© 2013 OLIMEXINO-32U4 user's manual 1.2 Similar boards OLIMEXINO-32U4 is an ARDUINO-LEONARDO-like board with ATmega32U4. It is a powerful board considering its low price but yet a starter board for the Arduino family. The more powerful Arduino board we have in the range is OLIMEXINO-328 – based on Arduino Duenomilanove. It has a more sophisticated supply circuit, USB OTG connector and there are more Arduino projects available. 1.
OLIMEX© 2013 OLIMEXINO-32U4 user's manual CHAPTER 2 INTRODUCTION TO ARDUINO 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.
OLIMEX© 2013 OLIMEXINO-32U4 user's manual 2.1 First steps with Arduino IDE Depending when you purchased the board there are two scenarios since the PID (product ID) which is stored in the firmware and expected by the IDE is different between versions 1.0.0 and 1.0.1 (1.0.1 is the first release of the Arduino IDE with official support for Leonardo). 2.1.
OLIMEX© 2013 OLIMEXINO-32U4 user's manual From File->Open navigate to the examples folder which is found in the Arduino IDE installation folder. Choose a simple example to begin with like BlinkWithoutDelay.ino and open it. Click verify and after it compiles click “Upload”. Voila, you have uploaded code to your Arduino device. Now start exploring the world of Arduino! More info and help on the software can be found and the official Arduino web site: http://www.arduino.cc/.
