I want to connect a Piezo-disk across two output pins of either a
pic84/pic71 and drive it directly by toggling the pins, ie pa0=1,pa1=0
pa0=0,pa1=1,,,pa0=1,pa1=0. can anbody see a problem with capacitance.
Would it be necessary to put a load resistor across the transducer..?
The 84/71 will be driven from a 2.5-3v psu.
Its function is to beep on a key press and use minimum power.
comercial dc units use more power than I have to spare.

,I've seen things you people wouldn't believe.
Attack ships on fire off the sholder of Orion.
I watched C-beams glitter in the darkness at Tan Hauser Gate.
All those moments will be lost in time,
like tears in rain.
Time to die.

Remember now, watch out for the Fairies......!
