    i have fingerprint u.are.u modul, which has usb interface

    i need to transmit data from fingerprint modul to pc/server via lan/ethernet and display the feedback in lcd graphics

    i have idea , to connect my u.are.u fingerprint to avr via ft232, then to ethernet via enc28j60

    u.are.u -> usb -> ft232 -> avr -> spi -> enc28j60 -> lan

    but i have no idea how to implement it … could someone here help me?

    do i have to receive serial data from fingerprint modul, save in byte array and then send to enc28j60 using spi?

    or do you have any better idea?

    thanks in advance, sorry for my english

    Hi Alfia,

    Your implementation idea sounds perfect for me. Why don’t you proceed with it?

    The only concern is with the memory required to store the data of the finger print image. Please make sure that you can allocate that much amount of memory in your mirocontroller.
