Tennsy OctoWS2811 Questions Counter

Hi,

I have 4 time a 32*16pixels WS2812B led matrix on my desk. I would like to show a 2 digit counter on this "matrix". So i connected the leds together.

So my question is if there is a libary to show something on the ws2812B leds. Im using the OctoWS2811 Adaptor to connect the "matrix" to the Tennsy.

Maybe someone has some experience with this leds ;-)

Thans Gibbedy, one line is working. But i put i put the 32x 8 matrix together as a square. So i have now 32x32 pixel. All the maxtrixes are connected in a row. I would like to drive it over on pin.

The text should go from the left to the right side over all 4. I would like to use it as one big matrix

no only the top matrix is doing some strange scroling but the text is not readable.

Code:
#include <Adafruit_GFX.h>
#include <Adafruit_NeoMatrix.h>
#include <Adafruit_NeoPixel.h>
#ifndef PSTR
 #define PSTR // Make Arduino Due happy
#endif

#define PIN 2

// MATRIX DECLARATION:
// Parameter 1 = width of NeoPixel matrix
// Parameter 2 = height of matrix
// Parameter 3 = pin number (most are valid)
// Parameter 4 = matrix layout flags, add together as needed:
//   NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
//     Position of the FIRST LED in the matrix; pick two, e.g.
//     NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
//   NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs are arranged in horizontal
//     rows or in vertical columns, respectively; pick one or the other.
//   NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns proceed
//     in the same order, or alternate lines reverse direction; pick one.
//   See example below for these values in action.
// Parameter 5 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)


// Example for NeoPixel Shield.  In this application we'd like to use it
// as a 5x8 tall matrix, with the USB port positioned at the top of the
// Arduino.  When held that way, the first pixel is at the top right, and
// lines are arranged in columns, progressive order.  The shield uses
// 800 KHz (v2) pixels that expect GRB color data.
Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(32, 8,4,1, PIN,
  NEO_TILE_TOP   + NEO_TILE_LEFT   + NEO_TILE_COLUMNS   + NEO_TILE_ZIGZAG +NEO_MATRIX_TOP     + NEO_MATRIX_LEFT +
  NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG ,
  NEO_RGB            + NEO_KHZ800);

const uint16_t colors[] = {
  matrix.Color(255, 0, 0), matrix.Color(0, 255, 0), matrix.Color(0, 0, 255) };

void setup() {
  matrix.begin();
  matrix.setTextWrap(false);
  matrix.setBrightness(40);
  matrix.setTextColor(colors[0]);
}

int x    = matrix.width();
int pass = 0;

void loop() {
  matrix.fillScreen(0);
  matrix.setCursor(x, 0);
  matrix.print(F("HELLO "));
  if(--x < -50) {
    x = matrix.width();
    if(++pass >= 3) pass = 0;
    matrix.setTextColor(colors[pass]);
  }
  matrix.show();
  delay(50);
}

With this code is starting on top and scrolls from top row to from right to left and then to the next part of the matrix.
 
i updated again..
the matrix declaration is wrong and needs to be ROWS not COLUMNS I think.

why is the 4,1 there?

Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(32, 8,4,1, PIN,
NEO_TILE_TOP + NEO_TILE_LEFT + NEO_TILE_COLUMNS + NEO_TILE_ZIGZAG +NEO_MATRIX_TOP + NEO_MATRIX_LEFT +
NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG ,
NEO_RGB + NEO_KHZ800);

see the example i posted and maybe google search videos on neoMatrix library
:)
