AVR®: Sending "Hello, world!" from the USART
In this video:
- Provide relevant community developed training materials for a useful USART_putstring() function.
- Modify this to call our USART_Transmit() function.
- Use delays for testing purposes.
- Put additional functionality into USART_irq.c and the function prototype to USART_irq.h, so main remains clean.
