Hi Manoj,

I discovered this site a short time ago, seems to be very intuitive.

At the end of the day much of this is simple math

You take the APB clock and divide it by the Prescaler, and then further divide by the sum of the bit-quanta settings.

ie bit rate = (APBCLK / Prescaler) / (a + b + c)
