    Hi All,

    Newbie has to control a FM module. What does he has to pay attention?

    For this FM audio function,

    1. I can save/load x channels.( x is a constant number )
    2. power on / power off
    3. switch to the specific channel of x channels.
    4. Only 3 PIO for host controller.

    Best regards,

    Dunno mate. That would depend on the application.

    This module major function is to pass audio ( not to receive FM radio
    broadcast ) through it.

    approximately, it is a very small power of FM broadcast device that
    broadcasting some audio/video data.

    The channel selecting is for select broadcast channel only. : )

  5. I believe this group should assign one person full time to interface,
    assist and distill information from Boki before introduction to SED. His
    multiple task are so interesting that it could keep this group
    delightlyfully busy . That person must be multi lingual and posses a wide
    technical base, My nomination is Sephro.

    How big is 'x'? 1? 1,000,000?

    How do you interface to the transmitter (or receiver, I couldn't figure
    that out) you want to control? If it has a control interface, hook to
    that with a PIC.

    x is <10.

    This is a FM transmitter.

    I have two choice, I2C and general PIO, I don't know how to decide it

    PIC ... do you mean pin control or ....

    Thank you very much for your advice!

    Best regards,

    It's irrelevant that it's an FM transmitter. How is the control of it
    done? How can you interface to it? Then look at how your controller or
    PC can interface, *then* decide on a link method.

    PIC -
