In my case I'm using a piezo buzzer that needs a waveform to drive it.
I'm receiving a good sound in around 4KHz. So, 4KHz is 250uSec and for testing I write a endless loop:
while(1) {
P3^2=1;
nop(230);
P3^2=0;
nop(230);
}
This code is not good! I want to control the beeps - length/period and etc.
Please advice.
