  • Sir, i just wanted to have an idea of the programming involved for 89c51 controller , where the controller must accept the incoming serial data at its serial port and write all the data to the External EEPROM (These data are nothing but the Active tag ID's attached to the objects nearer to a passive reader in an RFID System). After these data are stored into EEPROM, then the other task of controller is for comparing the incoming serial Tag ID's with the Tag ID's stored in the EEPROM, if they are same then convert these incoming Tag id's into a string and then send it to the output port., and controller also must be programmed such that there is a continuous updation of the data stored in the EEPROM .................Sir we have never worked before with External EEPROM interface, data access and Programming, kindly guide us about the programming and interfacing concepts .Thank you , seeking diligently for your reply..

  • So, as already suggested to you several times, have you actually spent any time doing any of your own research in this?

    Have you googled?

    Have you looked at the datasheets for the chips involved?

    Have you looked on the manufacturers website at the support materials available - examples, application notes, tutorials, etc,...?

    Have you reviewed your class notes, text books, etc?

  • more like 'asking dilligently'

    every post has resulted in an (often garbled) post asking the same question again.

    the twin posters have stated several times they are 'trainees', I wonder why do they not ask the 'trainer'.

  • Have you googled?
    Yes, We did it. Got information but still we are working on it.

    Have you looked at the datasheets for the chips involved?

    Yes, We have detail information abt our 89c51 abd EEPROM.

    Have you looked on the manufacturers website at the support materials available - examples, application notes, tutorials, etc,...?

    Yes, We have Interacted with them and we have got notes everything.

    Have you reviewed your class notes, text books, etc?

    Yes, We have done that all Time.

    Why I am here?

    We have idea, But we wanted Ideas and reviews from experts. Thanks for your replies. I think We are in right path in accomplish in this project.

  • "We have idea"

    You have not shown any evidence of that here.

    "we wanted ... reviews from experts"

    You should be talking to your instructors/tutors to review your progress on your assignment. Nobody else knows what the requirements are for your project!

    And, anyhow, nobody can review your ideas when you don't say what those ideas are!

    "I think We are in right path in accomplish in this project"

    Again, you should be reviewing that with your instructors/tutors
