Implementation of USART on AVR Microcontroller Based Embedded System Platform

In Embedded systems communication between two devices is very important and is frequently required. Communication between 2 devices can be in parallel or serially. But in many cases serial communication is used. It is frequently required to use serial communication. Also we are unable to interface a memory device such as EEPROM to the AVR series of microcontrollers directly. For that we require a serial communication protocol either I2C or SPI. Also this project increases one’s knowledge on the protocols widely used.
