Motivation

Bridge the gap between real (analog) world and computer (digital)

What can you create?

How to go about prototyping

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…)

• Two ATMega microcontrollers   PIC 18F8720 microcontroller in an 80-pin TQFP package.

• Interrupts - real time response to events in the embedded system.

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

Intel 1702A EPROM

• Today – 32bit Microcontrollers as cheap as 1$

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)

Example (if there’s time…) Bread board

Ex1• PWM – Pulse width modulation

• Light a led using PWM and video it – you will experience aliasing.

• Use the Aliasing to flash your ID• & record it. Have something to

indicate time units• Be creative!

• Submission- Email to Amit on behalf of team containing ID’s and a video with your solution.
