Smartcard Communication

about all software i fond at source frog all work with alredy operating system in card
but i want 2 make a new operating system and new routeen
how can i do it

for that you will need to start from scratch.... design how you want it to work and then write code to make it work. commercial smartcard OS's are almost always written in C and/or assembler and they tend to be pretty complicated.

That said, designing an entire smartcard OS is as simple or complicated as you need it to be; it all depends on what features you need. there is going to be a general amount of knowledge in programming that is needed to do a project like this; basically the same as you would need to write code for 2 microcontrollers and have them talk to eachother. if you can do that then you should have no problem...

i have simpic v 6.5 . you can try it form

yes thats it a pic programer and a phoenix/smart mouse programer to program a gold wafer.

i have built reader / writer below,



could anyone share a code with me?
i really have no idea about the data transmission between PIC and gold wafer card

look at this schematic,


does anyone have idea about the communication between PIC and gold wafer card (represented by pic16F84)?

thanks for your help

mm, let me explain where i'm at...

i will build a gold pic card reader and writer using PIC16F877.
it means the gold wafer card doesn't connect to PC

i know about the configuration of the gold wafer, which is like figure below

there is vcc, mclr, rb7 (serial programming clock), rb7(serial programming data), and ground.

if i write the gold wafer card from PC, i use phoenix / smarthouse programmer (the circuit was posted before). i can write the gold wafer card as like as write an usual PIC. it means i may write it in assembly language, right? (please answer..)

then,
i want my PIC16F877 to read and write the gold wafer card. Look at the configuration pin of gold wafer card, there's only rb6 (sclk), rb7(sda), vcc, gnd, and mclr. if there're a TX and RX pin, i can communicate via USART. but there are not. I think, i communicate with gold wafer card using rb6 and rb7 pin only. here, i don't know how.

i need some help about the code or any theory. (i hope the code )
1. about the code that i write to gold wafer card from PC
2. about the code that i write ti my PIC16F877 (that use to read an write the gold card)

any idea?
i hope y'all understand about i explained above. (sorry, my English is bad)

here is the mentioned ebook "smartcard developers kit"

Hi,

What kind of help do you need?
