Problem While Communicating between two Microcontroller using SPI

Started by dev_optiwave September 25, 2006
Hi All,
I am facing a problem while communicating
ATMEGA128 (Master) & ATMEGA325(sLAVE) using SPI.
i am able to send single byte properly but
whenever sending string ( 10 byte),same time
it's come properly same time not.
when i checked Master out & Clock it's reached
properly upto slave.
i am using AVR Application note 151 as a ref.
Please suggest same idea for Duplex communication
between two AVR Microcontroller.

Thank a lot.

i guess,,, u have to send one byte at one time.....for each data transfer
session....

so if u send a string u have to make a function thta will send by a byte...
