HPWM does not work

[JVA]

Hello, I have a PIC 16F88 and the programme is:

   ;Chip Settings
   #chip 16F88,8
   #config OSC=INTRC_IO

   ;Defines (Constants)
   #define PWM_Freq 1
   #define PWM_Duty 50

   DIR PORTB.0 out

   'Main code
   do forever

'Turn up brightness over 2.5 seconds
For Bright = 1 to 255
HPWM 1, 1, Bright
wait 25 ms
next

'Turn down brightness over 2.5 seconds
For Bright = 255 to 1
HPWM 1, 1, Bright
wait 25 ms
next
   loop

This programme works well, but with PIC 16F1827 ¡Does not work! The programme is as follow:

;Chip Settings
#chip 16F1827,8
#config OSC=INTOSC

;Defines (Constants)
#define PWM_Freq 1
#define PWM_Duty 50

DIR PORTB.0 out

'Main code
do forever

'Turn up brightness over 2.5 seconds
For Bright = 1 to 255
HPWM 1, 1, Bright
wait 50 ms
next

'Turn down brightness over 2.5 seconds
For Bright = 255 to 1
HPWM 1, 1, Bright
wait 50 ms
next
loop

Can you help me?  Thanks

The 16F1827 has CCP1 on PORTB.3 by default. You can get CCP1 to use PORTB.0 using -

set  APFCON0.CCP1SEL on

or just set PORTB.3 as an output and use that.

Thank you very much.
And …  if I need PORTB.0 and PORTB.3 ?

Right. I see ….

For example:

set APFCON0.CCP1SEL , 0
DIR PORTB.3 out
set APFCON0.CCP2SEL, 0
DIR PORTB.6 out
