Two ways to drive a Piezo or a speaker from a PIC, folks;

 1 pin - single ended (Other side of the speaker to Vcc or to Ground.)
 .and.
 2 pin - differential (pull pin1 low, pin2 high, or vice versa, gives
you twice the voltage swing - +- Vcc as opposed to half that.)

 The latter does take 2 pins (You can figure out a transistor or gate
buffer if IO pins are scarce, though <G>)
