Simple circle on Nokia LCD

Using Arduino Displays
1

Hi all,

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.

Cheers,

Ben
