tft.fillCircle(int16_t x0, int16_t y0, int16_t r, uint16_t color)
- Effect:
Draw a solid circle on the TFT screen
- Parameters:
x0：x coordinate of the center point
y0：y coordinate of the center point
r：radius of the circle
color：teh color of the circle
- Example:
#define sclk 13
#define mosi 11
#define cs 5
#define dc 4
#define rst -1 // you can also connect this to the Arduino reset
#include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_ST7735.h> // Hardware-specific library
#include <SPI.h>
#if defined(__SAM3X8E__)
#undef __FlashStringHelper::F(string_literal)
#define F(string_literal) string_literal
#endif
Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, mosi, sclk, rst);
void setup(void) {
tft.initR(INITR_BLACKTAB); // initialize a ST7735S chip, black tab
tft.fillScreen(ST7735_BLACK);
tft.fillCircle(40, 40, 20, ST7735_YELLOW);
}
void loop() { }
