    Closed: Re: Microcontroller selection - higher baud rate

    I guess the formula for calculating the baud rates are below.

    SPBRG = (Fosc / (16 x Baud rate)) - 1, BRGH = 1 High Speed
    SPBRG = (Fosc / (64 x Baud rate)) - 1, BRGH = 0 Low Speed

    With BRGH =...

    This means that the nearest baud rate to 115200 with 16 MHz crystal in PIC16F876 is 16,000,000/(16*(1+7)) = 125,000, right ? where SPBRG register has to be written with 7.
