Smart card reading writing.

james.t

I have a smart card slot and card from parallax. There was objects written in spin, but i have changed boards and now am working with the parallax board that uses c, can any one tell me where i might find information on how the smart card is accessed and how i can read and write data to it..

Thanks in advance

The board doesn't care. As long as it's a Propeller-compatible language, it will work with your board.

The smart cards use I2C to communicate with the Propeller. There's a SimpleI2C library included with the SimpleIDE. Have a look at that. Each card that Parallax sells has a datasheet that describes how to communicate with it using I2C, so it should be simple to write your communications routines in C with the datasheets, the SimpleI2C documentation, and the Spin code from the Object Exchange.
