Hi Bruce,
Thank you for your detailed answer ! All is clear now.
I have adapted the code in a way that the led's never go below 12uS, that way the 'color' switch on and off effect (color switches on for 12uS instead of 1uS) does not occur. This makes the colors somewhat more pastel, but it is still a smooth fade and a cool effect.
And, yes, if i'm going to make a new design i will certainly use a larger external osc ..
Thanks for all your answers and information !
Best regards,
UB
