Display

The M5CoreS3 uses the M5GFX library as the screen driver. You can implement simple displays by referring to the API & examples below. For more API details, refer to the M5GFX source code.

Example Usage:

#include "M5CoreS3.h"

void draw_function(LovyanGFX* gfx) {
    int x      = rand() % gfx->width();
    int y      = rand() % gfx->height();
    int r      = (gfx->width() >> 4) + 2;
    uint16_t c = rand();
    gfx->fillRect(x - r, y - r, r * 2, r * 2, c);
}

void setup() {
    auto cfg = M5.config();
    CoreS3.begin(cfg);
    int textsize = CoreS3.Display.height() / 60;
    if (textsize == 0) {
        textsize = 1;
    }
    CoreS3.Display.setTextSize(textsize);
}

void loop() {
    int x      = rand() % CoreS3.Display.width();
    int y      = rand() % CoreS3.Display.height();
    int r      = (CoreS3.Display.width() >> 4) + 2;
    uint16_t c = rand();
    CoreS3.Display.fillCircle(x, y, r, c);
    draw_function(&CoreS3.Display);
}
