Lep pozdrav!

Spodaj pripenjam program za preizkus PWM na Atmega 16.
Zakaj mi deluje samo PWM od Timer1, PWM od Timer0 in Timer2 pa vedno sveti na polno, ne glede na to kkašno vrednost za širino pulza vtipkam (OCR0, OCR2).

Hvala.

Koda:

$regfile = "m16def.dat"
$crystal = 1000000
$hwstack=40
$swstack=16
$framesize=32

' TIMER0 PWM=B.3
' TIMER1a PWM=D.5
' TIMER1b PWM=D.4
' TIMER2 PWM=D.7

Config Timer1 = Pwm , Pwm = 8 , Prescale = 1 , Compare A Pwm = Clear Down , Compare B Pwm = Clear Down
Config Timer2 = Pwm , Pwm = On , Compare Pwm = Clear Up , Prescale = 1
Config Timer0 = Pwm , Pwm = On , Compare Pwm = Clear Up , Prescale = 1

Enable Timer0
Enable Timer1
Enable Timer2

Enable Interrupts
Start Timer1
Start Timer0
Start Timer2

Ocr0 = 10
Ocr1a = 10 'Pwm1a
Ocr1b = 10
Ocr2 = 10 'Pwm1b

Do

' Pwm1a = 255
'Pwm1b = 255

!nop
Loop

End
