Why is black black? Itself has put out can make black again, there may be some different pulse signal lead to flicker, check code, normal black can make again black should not flash,

After you have assigned to once with give light color, the assignment of the next color (including lights) have to wait at least 24 us reset time, or it may cause the lights flash other colors,

CodePudding user response:

Specification book has mentioned among each data refresh cycle must be at least 24 us, if less than this value assignment again you this flash is likely to happen, you have a look at your code, is it middle color when switching time is too short,
