Hello. It sounds weird but I want to "copy" the effect of the first 20 leds to next 20 leds (and next 20...)
to run at them same time without adding another strips to other data pins
I'm using neopixel library and how can I setup this using library function
thanks
You simply copy the bytes in the buffer and transfer them to the next 20 led’s worth of bytes higher up the buffer.
You have to do this from back to front. That is transfer the bytes 20 from the end to the end twenty and then work your way back through the buffer in groups of twenty until you reach the front.
Each LED takes three bytes.
