When I connect chain of LED strips to power from both ends, do I need to make the power line disconnect in the middle?

And that does nothing else then combining the RGB components into on 32bit number and placing that integer in a pixel buffer at position px. Just like this #define LEDCOUNT 300 uint32_t pxBuffer[LEDCOUNT]; // actually for the APA102 protocoll you need some extra bytes for leadin/leadout //uint32_t pxBuffer[1 + LEDCOUNT + LEDCOUNT/16 + 1]; // element 0 (leadin) ... LEDs ... 1 leadout clock per 2 LEDs (ceil) bool needRefresh; volatile bool canRefresh = true; uint32_t setAPA102Color(int px, ui…
