ok thanks
but
in the first websit you had given to me:
i know the function of the pins but i would like to ask you some questions because i am litte confused,,,,please be patient with me
1)at pin 4 ,,, if it is connect it means keeping the data and disconnecting it means not keeping the data? or if i only connect it for a while it erase the data? or what is it's use?
2)how to record data on it......i mean which pin should be (I) to record and which should be (I) to read the data.....or how can i read and write...not by using any language or software,,but by sending and recieving only (I or O) to the pins,,,,and how about order sequance and speed.
please........reply
thanks
