Tile Matrix question
hi , i'm trying to get the VU working , but i'm stuck with my display , i have four 8x8 ws2812 progressive board that i'm trying to tile them as 16x16 what would be the best wiring configuration to make 16x16 ??? ( i know esp to din 1st board , dout 1st board to din 2nd board etc...
i tried a few config but it's all mixed up
what should be the code config too ,also tried a few code similar to this ex:
NEO_MATRIX_TOP + NEO_MATRIX_LEFT + NEO_MATRIX_ROWS + NEO_MATRIX_PROGRESSIVE + NEO_TILE_TOP + NEO_TILE_LEFT + NEO_TILE_ROWS + NEO_TILE_ZIGZAG);
Can you show me a diagram of how your matrices are wired internally, and also to each other with the data path shown? It might not work for 2x2 anyway as I've never tried it.

the matrix board is cjmcu-8*8 (6 pins ws2812 led) top left din , +5 , gnd (depending on how you hold it in your hand) i took my multimeter to trace the wiring and from top left is the 1st led goes to the 8 led and goes back under the first led like a zigzag , same path as adafruit neomatrix [https://cdn-learn.adafruit.com/assets/assets/000/010/704/medium800/leds_hairy.png?1377844757]
