    Hi

    I have been trying to connect two Atmel AT91 SAM7x512 microprocessors and establish data transfer between them... for this i need some help in addressing one microprocessor so that the other can call it to perform some actions

    Have you decided over what link you will connect the two ARM processors together? Are looking at using a serial link or a parallel link?

    A serial connection should work just fine. You have a couple of choices from which you can choose. You have SPI, USART, and TWI for example.

    Can you provide some details of what type of data you wish to transmit over this serial link and data-speed?

    How fast do you need the data to be transmitted between micros? Do you have large amounts of data to exchange?
