Hi Jerson,

I understand your questions, let me explain some more :

I drive 3 powerled's directly from the mains using a led driver board. These led's are switched by FET's, each on it's own channel. The driver board itself is about 10x10mm, a pic with 3 pwm channels in a SO8 package is just not available. Everything larger won't fit the enclosure.

The driver cannot drive 2 or 3 led's at once, that's why i'm switching between the three. Doing so at a total delay (led1 delay + led2 delay + led3 delay)=1000Hz + some overhead.

Pauseus does it's work, and all is fading smoothly. Except for the first start of a color. This sticks to 12us. When a fade is started, the color that is being faded in does not start at 1 or 2 us but starts with an initial delay of 12uS.

Hope this makes my problem somewhat clearer ...

I did count the instruction cycles, i even did a cross comparison of the asm files, the one using a number @ wait 0 and the one using @ wait _ledRED both files are exactly the same and have the exact same length ! I played around with the variables, changed them to byte's, putting them in bank0 ....

Why would changing from a numeric value to a numeric value stored in a variable result in an overhead of 30uS, i just don't understand.
