    Hi,
    I want to do digital dictionary project. Project details are as follows...

    This will be portable device.
    Function:
    We have to enter the word from keypad. And the description of that word will be displayed on our LCD.

    Hardware:
    1. Controller
    2. Keypad ( Query or mobile keypad)
    3. Graphical LCD
    4. EEPROM

    According to me:
    We have enter the word from keypad. The controller will search the word from the dictionary database stored in EEPROM & if found then it will retrieve the related things from EEPROM and display on the LCD.

    MY Problem:
    1. Which MCU will be perfect for this project ?
    2. Is there any dictionary database available to be loaded into EEPROM ?
    3. What will be searching algorithm ?


    Request to all , if anyone can help me on above things then i will be ever grateful to him...

    You have to know how many pins you have to use for the keypad, same as the LCD display, in resume, the external peripheral I/O.
    Starting from this you may want a certain EEPROM memory.. I should take a look to PIC or some AVR.
    You can program both on Windows or Linux, an AVR does not need any IDE, with Linux you can program it in VI too :D you just need the correct header files..

    Hello,
    Is it possible if i take AT89S8252 ? EEPROM will be connected through I2C protocol.
