i build hardware that i will use a pic16f876 to interfacing the card, to read the passwoad on the card and check it. i want a help to write a programe to put the passwoard on the funcard(Ex: number (6423)
i will make the reset pin on the funcard active to disable the card by conected it with an active (i/o) line of the pic ,and when i put the card in the Smartcard socket the pic will sense that card by monitering the switch of the fun card socket whe it active the pic disable the reset i/o pin line , and active the card so the (atmel 90s8515) send that passwoard to the pic, so:
i want to write aprogramefor the (at90s8515)in first it make adelay for .5 second and send that password by the serial pin (mosi).i make atmel work as master mode of spi make the pins (mosi utput, sck ut put ,ss: output) and the buadrate is (f/4)
but i am just begining in learn assembly code of atmel but i dont have much time so i want a help in write that program that i will put it on the funcard

learn C, trust me it opens a whole new set of doors. Should be able to find a free c compiler for the atmel pros.
