OK, so my response was off target as much fun as it was to write. I need guidance in mapping 5 separate 8x8 WS2812b matrices Without the trouble and repetitive code that shows up in the switch/case code, that’s what arrays are for If you haven’t used them before now woukd be a good time to learn up on them. The switch/case could be an if/else chain, but this is what switch/case is good at if you haven’t used them.īetter: put the 5 real strips into an array of strip objects, then you can write it like tPixelColor(the Poxel, theColor) That might save some time depending on what you are actually doing with the entire combined display. You could set a flag to indicate that a real strip has been written to, then the strip shows could be skipped if no pixels had changed. When you would strip.show() (haha, strip show) elsewhere, you’d have to. / and so forth for the remaining 3 strips Int thePixel = theVirtualPixel - 64 * theStrip You posted no code, so the below is sketchy <- see what I did there? and makes lots of assumptions and is untested, but the ideas should be obvious: void mySetPixelColor(int theVirtualPixel, unsigned long theColor) In that case there would be 5 8x8 strips, each on its own pin. Writing is fairly fast, if you have the time this is the easiest way to go by far.Īnother way, what you have actually asked for, is to write functions that accept pixel numbers from 0 to 319, and within those functions figure out which strip to direct the data to. One way is to daisy chain them so they are now one longer strip of 5 * 64 (320) pixels, connected to one pin and declared in the code as one object. ![]()
