1.47Inch 172×320 IPS LCD Display SPI ST7789V3 Wiki - DFRobot

Introduction

This exquisite little display is a good choice for projects requiring colorful and clear displaying effects!
Based on ST7789V3 driver chip, this 1.47" display has 172×320 pixels with IPS any-angle viewing and SPI interface for communication. It comes with a 1mm frame and rounded corners. The display can be used to display text messages, images, animations or videos. Also, with the supported Arduino GLD and LVGL libraries, more amazing dynamic effects can be achieved.
It is widely suitable for DIY projects like mini game consoles, weather stations, pendants, clocks, video players, etc.

Sample Code 1 - Chinese Font Display

#include "DFRobot_GDL.h"

#define TFT_DC  D2
#define TFT_CS  D6
#define TFT_RST D3
#define TFT_BL  D7

DFRobot_ST7789_172x320_HW_SPI screen(/*dc=*/TFT_DC,/*cs=*/TFT_CS,/*rst=*/TFT_RST,/*bl=*/TFT_BL);
void setup() {
  screen.begin();
}

void loop() {
  screen.setTextSize(4);
  screen.fillScreen(COLOR_RGB565_BLACK);//Background color
  screen.setFont(&SIMKAIFont72pt);//Font size（12pt 18pt 24pt 36pt 48pt 72pt)
  screen.setCursor(/*x=*/10,/*y=*/120);//Text Position 
  screen.setTextColor(COLOR_RGB565_BLUE); //Text color 
  screen.setTextWrap(true);
  screen.print("你好");//Chinese Character 
  delay(2000);
}

Expected Results

Burn the codes into the ESP32-E, then the screen shows “你好” in blue.

Sample Code 2 - English Font Display

#include "DFRobot_GDL.h"
#define TFT_DC  D2
#define TFT_CS  D6
#define TFT_RST D3
#define TFT_BL  D7

DFRobot_ST7789_172x320_HW_SPI screen(/*dc=*/TFT_DC,/*cs=*/TFT_CS,/*rst=*/TFT_RST,/*bl=*/TFT_BL);
/* M0 mainboard DMA transfer */
//DFRobot_ST7789_172x320_DMA_SPI screen(/*dc=*/TFT_DC,/*cs=*/TFT_CS,/*rst=*/TFT_RST,/*bl=*/TFT_BL);
void setup() {
  screen.begin();
}
void loop() {
  screen.setTextSize(2);
  screen.fillScreen(COLOR_RGB565_BLACK);//Background color
  screen.setFont(&FreeMono24pt7b);//Font size(9 12 18 24)
  screen.setCursor(/*x=*/32,/*y=*/200);//Text position 
  screen.setTextColor(COLOR_RGB565_LGRAY);//Text color 
  screen.setTextWrap(true);
  screen.print("DF");//English char 
  delay(1000);   
}

Expected Results

Burn the codes into the ESP32-E, then the screen shows "DF" in grey.
