¿Cómo programar el TFT Display 1.3″ ST7789 con Arduino IDE?

Para programar este display es muy sencillo hay que utilizar dos librerías que podrás descargar a continuación:

• Adafruit GFX graphics
• Librería Arduino ST7789 Fast_master
  

Y a continuación realizar el siguiente código:

#define SCR_WD   240
#define SCR_HT   240
#include <SPI.h>
#include <Adafruit_GFX.h> 

#if (__STM32F1__) // bluepill
#define TFT_DC  PA1
#define TFT_RST PA0

#else
#define TFT_DC  8
#define TFT_RST 9
#include <Arduino_ST7789_Fast.h> 
#endif

Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST);
