Arduino sketch example: #include SPI.h #include Adafruit_GFX.h #include Max72xxPanel.h int pinCS = 10; // Attach CS to this pin, DIN to MOSI and CLK to SCK (cf http://arduinocc/en/Reference/SPI ) int numberOfHorizontalDisplays = 1; int numberOfVerticalDisplays = 4; Max72xxPanel matrix = Max72xxPanel(pinCS, numberOfHorizontalDisplays, numberOfVerticalDisplays); String tape = \Ayo belajar Arduino bersama DA Electronics\; int wait = 50; // In milliseconds int spacer = 1; int width = 5 + spacer; // The font width is 5 pixels void setup() { matrix.setIntensity(7); // Use a value between 0 and 15 for brightness // Adjust to your own needs matrix.setRotation(matrix.getRotation() + 1 ); // The first display is position upside down // matrix.setRotation(1, 1); // The first display is position upside down } void loop() { for ( int i = 0 ; i width * tape.length() + matrix.width() - 1 - spacer; i++ ) { matrix.fillScreen(LOW); int letter = i / width; int x = (matrix.width() - 1) - i % width; int y = (matrix.height() - 8) / 2; // center the text vertically while ( x + width - spacer = 0 letter = 0 ) { if ( letter tape.length() ) { matrix.drawChar(x, y, tape[letter], HIGH, LOW, 1); } letter--; x -= width; } matrix.write(); // Send bitmap to display delay(wait);
