Hi, what you want to do is called type casting,ie. you must explicitly
specify the type. I've included some sample code that uses it. Because the
beeper function expects a float but the knob function returns an integer,
you have to modify the value to a float.
ie.
/*
adjusts the frequency of the buzzer with the knob
*/
void main()
{
float h=0.0;
while(1){
printf("Press start to adjust pitch...\n");
start_press();
printf("Stop to quit\n");
while(1) {
h=(20.0*(float) knob()); <--see here
if (h<20.0){
h=20.0;
}
set_beeper_pitch(h);
beeper_on();
if (stop_button()) {
beep();
break;
}
}
}
}
Hope this helps, Duncan
