tft.setCursor(int16_t x, int16_t y)

• Effect:
  

Sets the coordinates of the starting point of printing texts on the TFT screen

• Parameters:
  

x：x coordinate of the starting point

y：y coordinate of the starting point

• 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.setCursor(10, 40);
  tft.setTextColor(ST7735_YELLOW);
  tft.setTextSize(0);
  tft.println("Hello World!");
}

void loop() {  }
