Power Control PWM, HELP needed

[Kloney]

Hi,
seems I should use Interrupt somehow which I don't have any idea about using it in such a thing..
anyway here's the code

DEFINE OSC 40
 portb = 0
 latb = 0
 TRISB = %11000000 ' pwm0-5 output
 PTCON0 = %00000000 '   (1:1) prescale , Free-running mode 
 PTCON1 = %10000000 'time base is on, Counting is up
PWMCON0 = %01000000 'Pwm0-5 enbbled for pwm output,Complementary
PWMCON1 = %00000001 
OVDCOND = %11111111
DTCON = %01110010 '5us dead-time
PTPERL = $E7
PTPERH = $03

I'm trying to generate 3 sinwaves with a 120 shift each to use it in a 3-phase inverter ,the output sinewave frequency should be 50Hz.
I think I can use the Lookup2 function to declare the array entries like this :

G VAR BYTE 
Arrayd VAR WORD   
 For G = 0 to 99     
LOOKUP2 [500, 531, 563, 594, 624, 655, 684, 713, 741, 768, 794, 819, 842, 864, 885, 905, 922, 938, 952, 965, 976, 984, 991, 996, 999, 1000, 999, 996, 991, 984, 976, 965, 952, 938, 922, 905, 885, 864, 842, 819, 794, 768, 741, 713, 684, 655, 624, 594, 563, 531, 500, 469, 437, 406, 376, 345, 316, 287, 259, 232, 206, 181, 158, 136, 115, 95, 78, 62, 48, 35, 24, 16, 9, 4, 1, 0, 1, 4, 9, 16, 24, 35, 48, 62, 78, 95, 115, 136, 158, 181, 206, 232, 259, 287, 316, 345, 376, 406, 437, 469], Arrayd     
duty[G] = Arrayd.LOWBYTE     
duty2[G] = Arrayd.HIGHBYTE   
NEXT

not sure if that is going to work

but I think this is not the problem here
