# ATmega238p to PC Serial Communication(RX/TX) using USART

A collection of sample codes for communicating with Linux/Windows PC from an ATmega328p microcontroller using USART in asynchronous mode.

## Code

- Sourcecode written in **Embedded C**. 
- Compiled using **AVR-GCC** using **Make** utility.
- Code can be uploaded using AVRDUDE and any compatible programmer.

## Hardware setup

- Code tested on ATmega328p (32 pin TQFP).
- ATmega328p Clocked with a **11.0592MHz external crystal**.
- USB to Serial Converter used to connect ATmega328p with PC 
- PuTTY used to receive and Transmit data
