• VDD / GND: Power supply (3.3V recommended) and ground connection.
• SCL / SDA: SPI clock and data signals for communication.
• RISORSE: Reset pin for initializing the display controller.
• CC: Data/Command selection pin (high for data, low for command).
• Servizio clienti: Chip Select pin (active low, enables SPI communication with the display).
• BL: Backlight control pin (typically for enabling/disabling or controlling backlight brightness).

5. Impostazione

Follow these steps to connect and prepare your display module for use with a microcontroller or development board.

1. Collegamento elettrico: Connect the VDD pin to a 3.3V power supply and the GND pin to the ground of your microcontroller. Ensure the power supply is stable and within the 2.8V-3.3V range.
2. SPI Signal Connection: Connect the SCL (Serial Clock), SDA (Serial Data), CS (Chip Select), DC (Data/Command), and RES (Reset) pins from the display module to the corresponding SPI pins on your microcontroller. Refer to your microcontroller's documentation for specific pin assignments.
3. Controllo della retroilluminazione: Connect the BL (Backlight) pin. This can be connected directly to 3.3V for constant backlight or to a PWM-capable pin on your microcontroller for brightness control.
4. Montaggio fisico: Secure the display module to your project enclosure or breadboard using appropriate standoffs or mounting hardware.

6. Istruzioni per l'uso

To operate the display, you will need to write firmware for your microcontroller that communicates with the ST7789 driver via the SPI interface.

1. Inizializzazione: After power-up, send the necessary initialization commands to the ST7789 driver. This typically involves a software reset, setting display orientation, color mode, and other display parameters.
2. Sending Commands and Data: Use the DC pin to switch between command mode (DC low) and data mode (DC high). All commands and pixel data are sent via the SPI data line (SDA) synchronized by the SPI clock (SCL).
3. Disegno grafico: To display graphics or text, define a drawing window (column and row address set) and then send the pixel data. The display supports 172x320 resolution.
4. Controllo della retroilluminazione: Control the backlight via the BL pin. For simple ON/OFF, set the pin high or low. For brightness control, use Pulse Width Modulation (PWM) on the BL pin.

Refer to the ST7789 datasheet for detailed command sets and programming sequences. Many open-source libraries are available for common microcontrollers (e.g., Arduino, ESP32) that simplify interaction with ST7789-based displays.

7. Manutenzione

Proper care and maintenance will extend the lifespan of your display module.

• Pulizia: Pulire delicatamente la superficie del display con un panno morbido e privo di lanugine. Per le macchie ostinate, utilizzare una piccola quantità di alcol isopropilico sul panno. Evitare detergenti abrasivi o spruzzi diretti di liquidi sul modulo.
• Gestione: Always handle the module by its edges to avoid touching the display area or sensitive electronic components.
• Scarica statica: Take precautions against electrostatic discharge (ESD) when handling the module, as static electricity can damage electronic components. Use an ESD-safe workstation if possible.
• Magazzinaggio: Conservare il modulo in un ambiente asciutto e privo di polvere, lontano dalla luce solare diretta e da temperature estreme.

8. Risoluzione Dei Problemi

If you encounter issues with your display module, consider the following troubleshooting steps:

• Nessun display / Schermo vuoto:
  • Verify power connections (VDD, GND) and ensure the module is receiving 3.3V.
  • Check all SPI signal connections (SCL, SDA, CS, DC, RES) for proper wiring.
  • Ensure the backlight (BL) pin is correctly connected and receiving power.
  • Confirm that the display driver (ST7789) is being correctly initialized in your code.
• Incorrect Colors / Distorted Image:
  • Check the color mode settings in your initialization code (e.g., 16-bit, 18-bit color).
  • Verify that pixel data is being sent in the correct format and byte order.
  • Ensure the display orientation settings match your desired view.
• Partial Display / Incorrect Resolution:
  • Confirm that the column and row address set commands are correctly configured for 172x320 resolution.
  • Check for any offset settings that might be shifting the display area.
• SPI Communication Errors:
  • Verify SPI clock speed is compatible with both the microcontroller and the display module.
  • Check for proper logic levels (3.3V) on all SPI lines.
