Problem with intensity.. plz help

[Dwayne]

Hello Srig,

Srig>>I am performing software pwm . the following works on multiple pins at
the same time doing software pwm.

For Duty = 0 to 999

For cycles = 0 to Cycle1
Portb = %00000000
Pauseus 999 - Duty
Portb = %00100000
Pauseus Duty
Next cycles

but what I was trying to do is make three separate pins turn on at the
same time but all three of them need to be on a different intensities.
for instance one has to be on at LED1 = (20%)
LED2 = (30%)
LED3 = (80%)

here is what I have so far.. not sure if it is working but just need
someone to verify that this will work. I was hoping that you would do
this for me.

To make 3 separate pins to turn on at the same time with different intensities, you must use a PIC chip that has three PWM's built into the chip. That I know of, there is only one PIC chip out there that has 3 PWM's. (But could be more)

The software PWM will not work. It is only good for one pin at a time. You will need the chip that has 3 hardware PWM's.

Then your code will be something like the following:

x=256*.2
y=256*.3
z=256*.8


HPWM 1,x,2000
HPWM 2,y,2000
HPWM 3,z,2000
