This tool will help you to calculate SPBRG registrer values for the USART (used to implement RS232, LIN, RS-485 serial ports) module. The low power variants (PICxxLFxxxx) are not listed, but you can select corresponding PICxxFxxx variant - calculation is the same. If you do not see specific MCU - use Generic 8bit or 16 bit setup.
