ultrasonic foggers

Hi

I want to make an ultrasonic fogger with pic 16f877
I currently know i need :
1,6mhz or 2,4 Mhz , 24-100v signal
and a special tyte of piezzo

I have this piezzo and i want to use mosfet witch give 24-100 voltage signal but i need the 1,6 or 2,4 Mhz driver signal....

So the problem is....

I have to make a program for the pic ...witch give in this signal....


thanx
 

Hi,
You Can use the PWM module in the Pic to generate the signal.

ok thanx...

but i have a problem..... i dont speak french.... because it is french doc...

if somebody understand page 276 will be interesting
 

I wrote a utility that writes the PR2 value and also the Prescaler value for T2CON in an array for Swordfish Basic. The utility shows all possible frequencies per oscillator and prescaler settings. It also shows the maximum possible resolution of the PWM duty cycle:
