Hardware Connection

• TFT_CS (Chip Select): Connect to digital pin 10 on the development board.
• TFT_RST (Reset): Connect to digital pin 9 on the development board. Sometimes this pin can be directly connected to the reset pin of the board or permanently connected to VCC if the screen always resets when powered on.
• TFT_DC (Data/Command): Connect to digital pin 8 on the development board.
• TFT_MOSI (Master Out Slave In): Connect to digital pin 11 on the development board (corresponding to the hardware SPI MOSI pin).
• TFT_SCLK (Serial Clock): Connect to digital pin 13 on the development board (corresponding to the hardware SPI SCK pin).
• TFT_MISO (Master In Slave Out): If the screen supports reading data from the Arduino board, connect to digital pin 12 on the development board (corresponding to the hardware SPI MISO pin). Not all TFT screens require this connection.
• VCC: Connect to 5V or 3.3V on the development board, depending on the voltage requirements of the screen.
• GND: Connect to GND on the development board.
• T_CS: Connect to digital pin 6 on the development board.
• PEN: This pin is optional and is used for touch interrupt signals. If the interrupt feature is not used, it can be left unconnected.

Usage Method

Installing Library Files (skip this step if already installed)

1. Open the Arduino IDE.
2. Go to “Tools” > “Manage Libraries…”.
3. Search for “Adafruit ST7735”, “ThingPulse XPT2046 Touchand” and “Adafruit GFX”, and install each library individually.

Enter the code:

Next, write the following code in the .ino file:
