[SOLVED] Due and SPI library and SPI pins?

Google DUE DAC SPI , and you will find a .pdf document which is a good example to show how one can use SPI on a DUE.

BTW, there is another way to use SPI protocole on a DUE, this is thru USART0 and USART1.

can someone teach me how to use MFRC522 in Arduino DUE? it is harder than using it on any other arduino boards. but my project requires me to use DUE. please i really need it.. TIA God bless
