AVR®: Understanding the USART Baud Rate Macro

 In this video:

  • Baud rate equations to set the USART Baud Rate Register (UBRRn), based on a required baud rate and CPU frequency.
  • Tables of UBRRn settings for different CPU frequencies.
  • How to debug in order to check that the macro used to set UBRRn matches the recommendation in the tables.
