UART0 and UART1 baud rate calculations

Started by dodge1955 February 23, 2006
Hi Roger,

Great program, thanks. One feature that would be great as well as
supporting non FBR LPC's is the ability to manually edit the required
baudrate field. i.e. if I wanted to run at 250000 baud (DMX) or 31250
baud (MIDI) or some other non standard rate. 

Thanks again for the tool, just some ideas for improvements.

Cheers

Martin

Thanks
