Text Scrolling

Create animated scrolling text using the Parola library. This can, of course, be achieved with frame animation as well, but by using libraries, we don't have to re-invent the wheel. The Parola library builds upon the MD_MAX72xx library end expands it by adding several features, such as alignment, scrolling, animations and much more.

Info

Make sure to import the library into your platformio.ini:

lib_deps =
  MD_MAX72XX
  MD_Parola

Challenges

Challenge 1

Make it so that the text changes after it finishes the animation.

Challenge 2

Change the direction and speed of scrolling with each new message.

Example

#include <MD_Parola.h>
#include <MD_MAX72xx.h>

#define HARDWARE_TYPE MD_MAX72XX::FC16_HW
#define CS_PIN 10
#define SEGMENTS 1

MD_Parola display = MD_Parola(HARDWARE_TYPE, CS_PIN, SEGMENTS);

void setup() {
    display.begin();
    display.displayClear();

    ledMatrix.displayScroll("Capyboard", PA_CENTER, PA_SCROLL_LEFT, 100);
}

void loop() {
    if (ledMatrix.displayAnimate()) {
        ledMatrix.displayReset();
    }
}
