PIC SPI need help...!!!

[hussain_kiet]

hi i am want to interface 4 pic u controllers as slaves to a main master controller
also a PIC using SPI technique.
Can any one plzzz give me some related tutorials with hardware and programming issues disscussed...!!!!


plzzz help me...


thanx in advance..!!!!

First start reading your PIC's datasheet.Learn how to initialize SPI registers?
Which language/compiler do you use? If you write in C , check your compiler's libraries.There must be some SPI library functions.

i am using c language with "CCS C" compiler and it has built in SPI functions
my master controller will be PIC 16F877 but i am still not sure about the slave controllers obviously it will any PIC supporting SPI...

now can you plzz guide me about the topology in which they can be interfaced
i.e the hardware circuit..



and by the way thanx for your interest
