    Hello;
    Well I have been trying for few weeks of struggle with PIC to make a project encrypting/decrypting strings using rf modules tx433/rx433.

    So decideded to drop the idea and was wondering if I can use keyboard -> tx433 ->rf -> rx433 -> parallel port?
    1)What do I need exactly?
    2)Do I need ht12E/ht12D?
    3)Just general idea about the assembly program I am going to write?
    I know how to program parallel port just want to know how keyboard is going to work with rf and pc!
    Thanks =)

    You can use transmitter / receiver ICs from Micrel or Linx / Linx. They are very easy to handle.
    Are you talking about a PC keyboard? Here are some informations on how to interface it.
