Hi
I have purchased an 8x32 pixels ws2812 flexible led panel screen and I have tested with this code.
#include <Adafruit_GFX.h>
#include <Adafruit_NeoMatrix.h>
#include <Adafruit_NeoPixel.h>
#ifndef PSTR
#define PSTR // Make Arduino Due happy
#endif
#define PIN 6
// MATRIX DECLARATION:
// Parameter 1 = width of the matrix
// Parameter 2 = height of the 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_GRBW Pixels are wired for GRBW bitstream (RGB+W NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(32, 8, PIN,
NEO_MATRIX_BOTTOM + NEO_MATRIX_RIGHT +
NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG,
NEO_GRB + NEO_KHZ800);
const uint16_t colors[] = {
matrix.Color(255, 0, 0), matrix.Color(255, 106, 0), matrix.Color(255, 255, 0), matrix.Color (0, 255, 0),
matrix.Color (0, 0, 255), matrix.Color (112, 39, 195), matrix.Color (255, 0, 255)};
void setup() {
matrix.begin();
matrix.setTextWrap(false);
matrix.setBrightness(10);
matrix.setTextColor(colors[0]);
}
int x = matrix.width();
int pass = 0;
void loop() {
matrix.fillScreen(0);
matrix.setCursor(x, 0);
matrix.print(F("Super Arduino"));
if(--x < -36) {
x = matrix.width();
if(++pass >= 7) pass = 0;
matrix.setTextColor(colors[pass]);
}
matrix.show();
delay(100);
}
But how do you write if you want 2 lines ?? and if you want more things, such as a face or a figure. Do not have a page where you can see / read all the commands you can use for all the things an 8x32 led panel screen can.
thanks
