MICROCONTROLLERS & ARDUINO Tanya Vasilevitsky Tatyana
[email protected] Motivation Bridge the gap between real (analog) world and computer (digital) Process raw electrical data into computer logic Process computer logic to electrical signals Microcontroller • A small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. • designed for embedded applications (remote controls , appliances, power tools…) • Interrupts - real time response to events in the embedded system. • Two ATMega microcontrollers PIC 18F8720 microcontroller i n an 80-pin TQFP package. Microcontroller • 1971 - Gary Boone and Michael Cochran succeeded in creating the first microcontroller, TMS1000. Contained: ROM, R/W memory, processor and clock on single chip • 1976 - Intel develops Intel 8048 with massive success • 1993 – EEPROM introduced (Replacing EPROM & PROM) & Atmel introduces first microcontroller with flash memory • Today – 32bit Microcontrollers as cheap as 1$ Intel 1702A EPROM Single-board microcontroller • A microcontroller built onto a single printed circuit board (PCB) • Provides all necessary HW: microprocessor, I/O circuits, clock generator, RAM Cheap, especially for development Emphasis on IO (digital/analog) The Make Controller Kit with an Atmel AT91SAM7X256 (ARM) microcontroller. Dwengo Arduino Open source HW & Software company from Italy Started in 2005 as a project for students at the Interaction Design Institute in Ivrea, Italy Initial team Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis A family of microcontroller boards Atmel microcontrollers & microprocessors https://www.arduino.cc/ Arduino Boards Arduino Uno Arduino Mega Arduino pro Arduino pro mini Arduino micro Arduino Uno Arduino mega Arduino pro mini Arduino pro Arduino micro Arduino Boards Arduino Zero Arduino Due • Arduino Zero (with debugger!) • Arduino Due • Arduino Yun • LilyPad Arduino Yun Shields • Ethernet shield • GSM shield • WIFI shield Other Boards • Raspberry Pi – Single board computer, dev.
