Description

Draw a filled circle or an anti-aliased filled circle.

Signature

• void TFT_eSPI::fillCircle(int32_t x, int32_t y, int32_t r, uint32_t color)
• void TFT_eSPI::fillCircle(int32_t x, int32_t y, int32_t r, uint32_t color, uint32_t bg_color = 0x00FFFFFF)
• void TFT_eSPI::fillSmoothCircle(int32_t x, int32_t y, int32_t r, uint32_t color, uint32_t bg_color)

Parameters

• ìnt32_t x: center x coord.
• ìnt32_t y: center y coord.
• ìnt32_t r: circle radius.
• uìnt32_t color: filling color.
• uìnt32_t bg_color: background color; If bg_color is not included the background pixel colour will be read from TFT or sprite.

Result

None

Example

#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  tft.init();
  tft.fillScreen(TFT_BLACK); // clear the screen
}

void loop() {
  // Draw a filled circle with a white color. 
  tft.fillCircle(120, 120, 50, TFT_WHITE);
  delay(1000);
}

In this example, we use fillCircle to draw a filled circle with the following parameters:

• x: 120 (the x-coordinate of the center of the circle)
• y: 120 (the y-coordinate of the center of the circle)
• radius: 50 (the radius of the disc)
• color: TFT_WHITE (the disc color)

This will draw a circle with a border color, centered at (120, 120) with a radius of 50 pixels.

If you want to draw the circle with a border color, you can use the drawCircle or the drawSmoothCircle methods instead.
