simple xmas light project not behaving....

look into Darrel Taylor's 3 channel software PWM code - it's interrupt based. I'm not sure if it's ready to run on a 18F4550. Your main loop would look something like this:

FOR x = 0 to 255 STEP 5
red = x 'REd fade on,
PAUSE delay
NEXT x

FOR x = 0 to 255 STEP 5
green = x 'green fade on,
PAUSE delay
NEXT x

ect...

The code you showed has some problems for sure.

The variables Duty and Scale are set to 1 at start. Then you do this

POWERUPRED:
for Aloop = 1 to DUTY
FOR Bloop = 1 to REDSCALE
HIGH RED
pause Aloop
LOW RED
pause (duty-Aloop)
NEXT Bloop
NEXT Aloop
HIGH RED
return

Rewriting with your declared values it looks like this

POWERUPRED:
for Aloop = 1 to 1
FOR Bloop = 1 to 1
HIGH RED
pause Aloop
LOW RED
pause (1-Aloop)
NEXT Bloop
NEXT Aloop
HIGH RED
return

Perhaps you see the problem now.

Jerson;
Ok thats weird...
The scale var is their if i want to slow down the change... so setting this to 1 is normal
The duty var is actually set to 100 but for some reason it's shown as 1...
Where did my zero's go?

Max;
I'm aware of DT's 3 channel PWM, however, the 18F4550 is only the development hardware i use for testing everything...
I will be buying some lower grade pic's to do the job... i want approximately 5-10 of these running different patterns around the house both inside and out...
