Re: UART0 and UART1 baud rate calculations

2006-02-26 by roger_lynx

Hi Sutton,

You might want to look at this LPC214x FractCalc I put together with a
PLL calculator, PDF and ASCII viewers.
It is a Win GUI applet; subject to continuous improvements, but usable.
Check the bottom of this page:

Hope this helps.
