hello everyone
I got the problem with the odd number of Clock to generate baudrate . I want to generate baudrate at 2400,9600,115200....and more ...
can u help me
best regard !
 

Re: How to generate Baudrate with the system clock 25.174 MH

25174000 * 6 /62935 = 2400.

25174000 * 24 /62935 = 9600.

25174000 * 48 /62935 = 19200.

25174000 * 96 /62935 = 38400.

25174000 * 288 /62935 = 115200.

Oh....
It's so easy..
Thank alots ...................................
 

How exactly are you going to mulitply and divide the system clock?
 

You can use a PLL to multiply.
But you don't need to multiply:
25174000 / 10489 = 2400
For serial communications, the baud rate doesn't have to be exact +/- 1% surely should be good enough.
