User Manual

Second, we need to set the correct initializations sequence. In the graphicstest source code, look for the lines as

follows:

comment out the first line, and uncomment the fifth, so it looks like:

Now upload the sketch to your Arduino. You may need to press the Reset button to reset the Arduino and TFT. You

should see a collection of graphical tests draw out on the TFT.

// For 1.44" and 1.8" TFT with ST7735 (including HalloWing) use:

//Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);

// For 1.3", 1.54", and 2.0" TFT with ST7789:

Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST);

// Use this initializer if using a 1.8" TFT screen:

tft.initR(INITR_BLACKTAB); // Init ST7735S chip, black tab

// OR use this initializer (uncomment) if using a 1.44" TFT:

//tft.initR(INITR_144GREENTAB); // Init ST7735R chip, green tab

// OR use this initializer (uncomment) if using a 0.96" 180x60 TFT:

//tft.initR(INITR_MINI160x80); // Init ST7735S mini display

// OR use this initializer (uncomment) if using a 1.3" or 1.54" 240x240 TFT:

//tft.init(240, 240); // Init ST7789 240x240

// OR use this initializer (uncomment) if using a 2.0" 320x240 TFT:

//tft.init(240, 320); // Init ST7789 320x240
