What is AVR ?

A CMOS 8-bit-microcontroller series from Atmel, based on RISC architecture. Most instruction are executed in a single clock cycle. The AVR consists of 32 general purpose working registers, flexible timer/counters with compare modes, internal and external interrupts and serial UART and programmable Watchdog Timer and power saving modes. The on-chip In-System Programmable Flash allows the program memory to be reprogrammed in-system through a SPI serial interface. Selected AVR can be self-programmed through a boot-loader.

AVR Hardware-Projects

I have designed and build the following projects:

• Build your own AVR Starter Kit
  Describes how to build your own AVR starter kit including the necessary adapter cable for in-system programming.

• Interfacing a HD44780 Based LCD to an AVR
  Explains how a character LCD module can be connected to an AVR

• Serial Port Interface for an AVR
  Interfacing an AVR with built-in UART to the PC using the MAXIM RS-232 driver.
