AVR ATMEGA BIT RATE-BAUD RATE CALCULATOR- ISR VECTOR NAMES ADDRESS



AVR ATMEGA 8 BIT RATE-BAUD RATE CALCULATOR- ISR VECTOR NAMES ADDRESS

          This EXCEL file consist of various calculations involved in AVR (Atmega 8) MCU system design.  This includes functions for calculating USART baudrate or UBBR values, TWI bitrate or frequency calculation, ADC values, ISR vectors, etc…
            The register description is also provided for guidance. 
            This helps in easier  debugging and designing of a AVR project.

List of calculations available in this file
  • USART
  • TWI
  • I2C
  • ADC
And also ISR vector names & addresses is included with this.
