Baudrate Divider Calculator for AVR Micros
An Excel spreadsheet is an extremely useful tool when you need to calculate a value to be loaded in the UBRR register of an Atmel AVR microcontroller. As most AVR programmers will know, these values depend on the crystal frequency used because they are derived from it. Without such a spreadsheet, such calculations are tedious.A Microsoft Excel spreadsheet called calcubrr.xls was developed for this purpose.
