AVR®: Using an App Note to Implement IRQ Based USART Communications

 In this video:

  • Find AVR® MCU application notes and source code.
  • Provide an overview of "AVR306: Using the AVR USART in C".
  • Copy relevant code into the project.
  • Add the Libc.h header file for interrupts.
  • Modify the USART initialization function to auto calculate the baud rate register and to use one stop bit.
  • Adjust interrupt vectors written for IAR to AVR Libc.
  • Debug to understand what happens when we hit the data register empty interrupt.
