Precautions Before Use

• The GDI interface must be used with a main controller that has a GDI interface.
• It is recommended to use Arduino 1.8.10 or a later version.
• Poor contact of the SD card slot may cause initialization failure; reinserting the SD card may resolve the issue.

Hardware Preparation

• 1 × Firebeetle 2 ESP32-E Development Board (SKU: DFR0654)
• 1 ×3.5" 480×320 IPS Capacitive Touchscreen (SKU: DFR1092)
• 1 × 18-pin FPC Cable
• Several Dupont Wires

Software Preparation

• Download Arduino IDE: Click to download Arduino IDE
• Download Arduino Library: Click to download DFRobot_GDL Library File
• Click the link to view: How to Install the Library?

• All demonstration demos for this product are stored in the DFRobot_GDL->example->basic folder.
• Before burning the demo, enable the corresponding instantiation function (DFRobot_ST7365P_320x480_HW_SPI).

Sample Code

Program Description: This is a UI control demo—a numeric keypad. First, click the text box to display the cursor, then click the numbers to show the corresponding digits in the text box. The "x" in the bottom right corner of the keypad is used to delete content in the text box.
