E-Ink Cubic M009F with GxEPD

Other Hardware Displays
1

Hello,
I have an e-ink display with an ESP32 board. I am trying to display some text on my screen, but I can't find a library that works consistently.
I have tried using GxEPD and GxEPD2, but they only work when I use #include <GxGDEW075Z09/GxGDEW075Z09.h> // 7.5" b/w/r, and then #include <GxGDEW075Z08/GxGDEW075Z08.h> // 7.5" b/w/r 800x480.
However, if I try using just the first one, it displays random things, and if I try using only the second one, it works the first time but doesn't work again after that.
I can't find any other good libraries or info for my display.

This is my hardware:

  display.init(115200);  // enable diagnostic output on Serial

  Serial.println("3");
  display.drawPaged(drawHelloWorld);

  display.powerDown();

  digitalWrite(LED_BUILTIN, LOW);

  Serial.println("setup done");
}

void loop(){};

const char HelloWorld[] = "test";

void drawHelloWorld() {
  Serial.println("drawHelloWorld");
  display.eraseDisplay();
  display.setRotation(1);
  display.setFont(&FreeMonoBold9pt7b);
  display.setTextColor(GxEPD_BLACK);
  int16_t tbx, tby;
  uint16_t tbw, tbh;
  display.getTextBounds(HelloWorld, 0, 0, &tbx, &tby, &tbw, &tbh);
  // center bounding box by transposition of origin:
  uint16_t x = ((display.width() - tbw) / 2) - tbx;
  uint16_t y = ((display.height() - tbh) / 2) - tby;
  display.fillScreen(GxEPD_WHITE);
  display.setCursor(x, y);
  display.print(HelloWorld);
  Serial.println("drawHelloWorld done");
}
