Display-ul LCD SPI 128*160 cu chipset ST7735

Am cumparat de pe aliexpress.com un display LCD 128*160 cu chipsetul ST7735.

Pentru a-l folosi am folosit libraria TFT_ST7735. Aeasta poate fi descarcata de la acest link. 

Alimentarea acestui display se face cu 3,3V. 

Conexiunile sunt urmatoarele:

Display LCD -------------------Arduino Uno

CLK ---------------------------- D13

SDA ---------------------------- D11

RS ------------------------------ D8

RST ---------------------------- D7

CS ------------------------------ D9

O imagine cu spatele afisajului o voi posta mai jos.

Sketch-ul folosit este urmatorul:

#include <TFT_ST7735.h>
#include <SPI.h>
TFT_ST7735 tft = TFT_ST7735();
#define TFT_GREY 0x5AEB

void setup() {
  tft.init();
  tft.setRotation(2);
  tft.fillScreen(TFT_GREY);
  tft.setTextSize(1);
  
  tft.fillRect(2, 2, 122, 20, TFT_CYAN);
  tft.setCursor(4, 4, 2);
  tft.setTextColor(TFT_RED);  
  tft.println("www.");
  
  tft.fillRect(2, 25, 122,20, TFT_CYAN);
  tft.setCursor(4, 27, 2);
  tft.setTextColor(TFT_RED);
  tft.print("  electronicstore");
  
  tft.fillRect(2, 48, 122, 20, TFT_CYAN);
  tft.setTextColor(TFT_RED);

  delay(3000);
}
