Display-ul LCD SPI 128*160 cu chipset ST7735

    In acest articol voi folosi 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. 

    Pretul acestui display este de 47 lei si se poate cumpara de aici.

    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
