16F1828 HPWM and ADC

[midali]

Thx Richard, now I understand.

Now, AN6 work corectly. The value of CCPR1L is 2 x adval. If I divide adval to 2 , exist a little diference betwen PWM1 and PWM2 on outputs (~ 0,8 units)

t2con=4
PR2 = 255
ccp1con=12

pause 200
'========================PROGRAM=============================
main:
adcin 6 , adval 
pause 10

CCPR1L = adval/2            ;set pwm
duty1 = adval

hpwm 2 , duty1, 2000 

high inh1
high inh2

goto main
end
'=============================================================

some more things to consider

1.

Many devices allow a selection of Timer resource for some or all of the PWM
channels. The HPWM command will automatically determine the preset Timer
selection upon execution. Note that PWM channels that share a single timer may
not operate at independent output frequencies. While duty-cycle settings are
always independent from one channel to the next, independent frequency settings
require independent timer resources.

you have not set any individual timer resource options [ CCPTMRS0 ]
so

t2con=4
PR2 = 255

settings get overwritten by use of

hpwm 2 , duty1, 2000

2.
you have not specified how your "pot" is connected , if its connected between vdd an ground then use of a fvr of 2.048 v is totally inappropriate and
may even damage your chip. analogue in voltage should never exceed vref


3.
all your trouble was probably caused by incorrect adc settings , hpwm1 should now work
