well it seems Im having a conversation with myself, instead of busting the few neurones I have left, I used the second option (prescaler 1:16) and I made it work, but the glitches are still there.

I initialized the PMW before the main loop using: HPWM 0,0,1000

and the registers as:
T2CON = %00000110 ' timer2 on, prescale 1:16
PR2 = 62 'per pic calculator

and every time I wanted to adjust the duty cycle I entered the value in the duty variable and called this subroutine:

CCPR1L = duty>>2
CCP1CON=%00001100 | (duty<<5)

As I said...the glitches remain... if I stop reading the ADC they dissapear and the PWM is steady

HELP !
