Sharing a way how to setup neopixel, set color and send simple patterns - Many thanks to @Gordon who mentioned this possibility via Uint24Array().
// load module var np = require('neopixel'); // pin data line is attached to var NPP= D16; // number of neopixel var countNP = 100; // use Uint24Array to store an address single pixel var neopixelStrip = new Uint24Array(countNP); // set color for first and last pixel var color = {r:20,g:0,b:20}; var c = color.g + (color.r << 8) + (color.b << 16); neopixelStrip.buffer[0] = c; neopixelStrip.buffer[countNP-1] = c; // flip neopixel np.write(NPP, neopixelStrip.buffer);
Send a pattern all over the neopixel strip
// Solution A // simple pattern "_ _ Green _ _" var fiveLEDs = new Uint24Array(5); fiveLEDs[2] = 30; // fill buffer with a pattern array and count var nps = E.toUint8Array({data:fiveLEDs.buffer,count:20}); // Solution B // fill buffer with pattern for ( i = 2; i < countNP; i +=5 ) { neopixelStrip.buffer[i] = 30;
