Generate tone

  1. Hello everybody,

    I am new to this newsgroup and also new to microcontroller programming
    and electronics.

    I need to generate a tone with a PIC. It is attached to a codec that can
    play the sound.
    Ideally I would like to have a function that would get a frequency as
    input and that would generate a simple tone of that frequency.
    I know I have to generate a sin wave of a certain amplitude and
    frequency but I don't know how to do that in C for PIC and also what to
    send to the codec (I guess I have to sample the wave and send a certain
    amount of values of it).

    Any suggestion or advice would be greatly appreciated.

    Thanks a lot.
