    Here is the location for Steve's Multi-Calc. It is quite helpful.

    If you wanted 8 bit PWM using the hardware, you could shift your 8 bits to change it to 10, matching the hardware.

    something like this:
    Code:
    DUTY1 var word
 
DUTY1 = 255                    'put in some 8 bit value
DUTY1 = DUTY1 <<2          'shift your 8 bits to 10 bits
CCP1CON.5=DUTY1.1       ' load CCP1 duty value            
 CCP1CON.4=DUTY1.0       '      with Duty1 
CCPR1L=DUTY1>>2
