    Default External Eprom

    Hi guys,

    Just after a simple bit of advice as I've never hooked up an external Eprom to a PIC before.

    I have a 24LC256 and want to connect it to a 16F877A (possibly an 18F4550 - 40 pin). Can I connect the two data pins from the Eprom to any pins on the PC (RB7, RE0 etc) or do they need to be connected to dedicated pins in the same way as USB / RS232 ports are connected to dedicated pins ?

    any pins are ok for I2Cwrite or I2Cread functions.
