Hi , i have written a program with fastavr compiler to use spi ,
but if i coonect to SS pins of both avr together it works fine , but when i connect the SS pin of master avr to vcc and SS pin of slave avr to Ground , it does not work or it gets wrong numbers !?! why ?
(i do this because maybe i want to use multi slvae avrs)
please help me !
thanks in advance
