polling or interrupt driven transmission and receiving.

2007-11-08 by bigningbo

Hi,

I try to write a routine for RS232 communication between PC and AVR.
Which  way is best if I transmit a string to PC by using a interrupt
driven transmission or not by using interrupt? How will performance
affects if a string is long by interrupt driven transmission? Will
interrupt occur character by character? Thanks in advance!

Best Regards
Alex
