Hi!

I'm trying to design a smartcard reader for asynchronous cards (protocol T=0) and for synchronous cards (protocol S=9 as SLE4428 and protocol S=10 as SLE4442) with a PIC microcontroller, but I don't know how to implement really this, because all two prococoles uses different clock and protocol.

Then I need suggestions about the implementation, for synchronous, can be used a SPI peripheral if it is complemented with any I/O pin? For asynchronous, the power is using UART peripheral, but the uC must make the clock for card, then, how can I make this clock? And, how can I combine all two protocols using the same pins?

Thanks in advance

Hi


See PE electronic site they have full free project for read smart card hardwar + software + kit

All the best

synchronous smartcard

Hi!

What is PE Electronic site?? I try to find it by google but I can't find it...

Thanks in advance

example sle4442 program for pic

Hi Bobcat1

I also study something about T0 smartcard. Could pls show me exactly PE site ?

sle4442 pic project

Card Pardaz Pars has a full range of smart card reader products, you can contact them, they also have a reader that can work with SLE4442 and SLE4428 memory cards.
