#AVR-USART

AVR-USART is my collection of useful methods to configure USART on AVRs.

Currently supported AVRs are:

• ATMEGA164A
• ATMEGA164PA
• ATMEGA324A
• ATMEGA324PA
• ATMEGA644A
• ATMEGA644PA
• ATMEGA1284
• ATMEGA1284PA

Installation

1. Copy usart.h and usart.c to your project source folder.
2. Add #include "usart.h" into your source code

Usage Examples

Writing "Hello World"

usart_set_baud(&usart0, USART_BAUD_RATE_9600);
usart_enable_writing(&usart0);
usart_write(&usart0, 'H');
usart_write(&usart0, 'e');
usart_write(&usart0, 'l');
usart_write(&usart0, 'l');
usart_write(&usart0, 'o');
usart_write(&usart0, ' ');
usart_write(&usart0, 'W');
usart_write(&usart0, 'o');
usart_write(&usart0, 'r');
usart_write(&usart0, 'l');
usart_write(&usart0, 'd');
usart_write(&usart0, '!');

Reading

usart_set_baud(&usart0, USART_BAUD_RATE_9600);
usart_enable_reading(&usart0);
char c = usart_read(&usart0);

Note

This is a work in progress!
