It is smoother and easier to implement for me.
I have no limit on the number of pins to manage
I am using PCA9685 to control LED room illumination
And I set the smoothness with the help of time and the divider coefficient

On System#Boot do let,1,0 let,2,0 endon on Kitchen_Led#Led3 do if [Kitchen_Led#Led3]>0 timerResume,1 gpio,14,0 pcapwm, 14,3000 let,2,round([Kitchen_Led#Led3]/3) loopTimerSet_ms,1,50,[var#2] else timerPause,1 let,1,0 pcapwm, 14,0 pcapwm, 0,0 pcapwm, 1,0 pcapwm, 2,0 endif endon On Rules#Timer=1 do if...
