Could anyone help me. I want to know the simplest way to display a black circle on a nokia 5110 lcd screen using the adafruit GFX library. Can you call it using a simple ellipse function? I'm just not entirely whats in the library to call.

#include <Adafruit_GFX.h>
#include <Adafruit_PCD8544.h>
Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);
void setup() {
//Serial.begin(9600);
display.begin();
display.setContrast(60);
delay(2000);
// clears the screen and buffer
display.clearDisplay();
}
void loop() {
// draw circles with center pooint at the center of the screen
// upto "display.height()" pixel radius
for (int16_t i=0; i<display.height(); i+=2) {
display.drawCircle(display.width()/2, display.height()/2, i, BLACK);
display.display();
delay(100);
display.clearDisplay();
}
}
