Tft.fillTriangle()

tft.fillTriangle(int16_t x0, int16_t y0, int16_t x1, int16_t y1, int16_t x2, int16_t y2, uint16_t color)

• Effect:
  

Draw a solid triangle on the TFT screen

• Parameters:
  

x0：x coordinate of the apex

y0：y coordinate of the apex

x1：x coordinate of the bottom left point

y1：y coordinate of the bottom left point

x2：x coordinate of the bottom right point

y2：y coordinate of the bottom right point

color：the color of the triangle

• 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.fillTriangle(43, 30, 40, 90, 80, 120, ST7735_RED);
}

void loop() {  }
