![]() ![]() PB2 PB3 also used as Analog Input 0 (AIN0) and Analog Input 1 (AIN1) 44 The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH) and further refined and developed at Atmel Norway, the Atmel daughter company founded by the two chip architects. The Atmel AVRTM is a family of 8-bit RISC microcontrollers produced by Atmel. AVR C compiler will integrate all required programs together – More about AVR C compiler when presenting Lab 1 10 – Provides many useful assembly programs used by your C programs. ![]() CodeVision AVR C Compiler Professional version – Installed in 20 PCs in room EN229 – Compile programs with more than a thousand instructions.Final Project – Hardware – Software – Presentation – Report.Labs – Lab 1: Introduction to AVR STK500 Hardware/Software, a couple of simple c programs – Lab 2: A/D converter – Lab 3: Optical Sensors – Lab 4: 4 bits D/A converter – Lab 5: Controls and Feedback – Lab 6: Motor Control - open loop – Lab 7: Motor Control - simple feedback control – Lab 8: Motor Control - proportional feedback control 8.Related Component Topics – Common Interfaces – Part Packages 7.Microcontrollers – Don’t have keyboard and monitor jacks – Must use ports to perform I/O.What makes a microcontroller: – Self Contained.Modems MPEG decoders Network cards Network switches/routers On-board navigation Pagers Photocopiers Point-of-sale systems Portable video games Printers Satellite phones Scanners Smart ovens/dishwashers Speech recognizers Stereo systems Teleconferencing systems Televisions Temperature controllers Theft tracking systems TV set-top boxes VCR’s, DVD players Video game consoles Video phones Washers and dryers Lots more of these, though they cost a lot less each.Ī “short list” of embedded systems Anti-lock brakes Auto-focus cameras Automatic teller machines Automatic toll systems Automatic transmission Avionic systems Battery chargers Camcorders Cell phones Cell-phone base stations Cordless phones Cruise control Curbside check-in systems Digital cameras Disk drives Electronic card readers Electronic instruments Electronic toys/games Factory control Fax machines Fingerprint identifiers Home security systems Life-support systems Medical testing systems Nearly any computing system other than a desktop computer – Billions of units produced yearly, versus millions of desktop units – Perhaps 50 per household and per automobile Embedded computing systems – Computing systems embedded within electronic devices – Hard to define.But there’s another type of computing system – Far more common.Most of us think of “desktop” computers – PC’s – Laptops – Mainframes – Servers.Lecture 1: Embedded Systems Overview, AVR Hardware/Software Introduction ![]()
