Im about to start my first ever Propeller project and will be using a smartcard reader. Has anyone got any experience/examples of using such a device.

Thanks... Karl

    UPDATE! Since my last post i've got my card reader and serial display working but I am having problems with addressing the #32322 card? I can read some data from the card but dont yet understand fully the memory allocation and addressing.

    Can anyone help? Whats a good resourse of information and has anyone got some good examples of reading and writing to htese cards?

    Thanks Karl

    Hi Jon,

    I have looked at your code and it helped me lots but I could not work out what the structure of the memory and address allocation was. Do you have any other documentation?

    Thanks

    It's an EEPROM in disguise: http://www.issi.com/pdf/24C02A.pdf (locked at address %000 which is why you can't drop it onto the boot EEPROM buss).

    Hi Jon,

    Only just had time to look at my project again. Am I right in thinking there are just 8 pages (%0000 to %1110) that store any value from #00 to #FF?

    Thanks

    Yes, and that is handled by the putpage method.
