Serial Port

#1 Post by merlin » 28 Nov 2006 19:04

Hello users,

I made some tests with the UART Library it woks fine up to 19200 baud.
If I try to use a higher baud rate the routine will not work anymore.
Is there any particular reason for it?

Has someone use a higher baud rate without Problems?
Any help is appreciated.

Regards
Merlin

I havn't tried but you could try to use a oscillator with some higher frequency. It could work :)

by defualt all atmega microcontrollers are programmed for internal 1mhz. So you have to change the fuse bits to program for external crystal and for higher frequency the error should be low as possible
