USI in ATTINY2313 for SPI

2005-01-05 by Ridho Alpha

hello

this is my first project with ATTINY, so compact...ok...i want to use 2 ATTINY2313 as slave and 1 ATMEGA16 for master...since for slave AVRs needs to make low the /SS for SPI...but the ATTINY2313 has no /SS pin....

so can i use EXTERNAL INTERRUPT 0 pin from ATTINY2313 (slaves) to be driven low by master????

like example below (only for /SS and SCK):

MASTER SLAVE 1 (ATTINY2313) SLAVE2 (ATTINY2313)

PORTB.0 ---------------------------------- INT0 (PD.2)

PORTB.1 -----------------------------------------------------------------------------------------INT0(PD.2)

PORTB.7 (SCK) ----------------------------PORTB.7(USCK) -------------------------PORTB.7(USCK)

is it true????please help me

thank you
