    Requirements

    >Resolution:Maximum 20mV
    >Range:--2.5Vto +2.5(should be adjustable 2 buttons-up/down)
    >Frequency Range:0 to 10 kHz (should be adjustable 2 buttons-up/down)
    >Waveforms:square/sinusoidal/Traingular(should be selected using toggling 1 button)
    >When the systen is powered on,the frequency,level and waveform shape used on the last use should be used as the default values

    Can u tell me which PIC is good for make this Signal Generator?

    You could use a PIC micro and an AD9833.

    The required frequency, waveform and level can be sent to the AD9833 over the three wire interface. They are quite easy to use, but you really must read the date sheet very well.

    He is trying to control output levels. How would you do that with the PIC and with the AD9833?
