    GPIO Configuration

    GDI Display Interface

    This interface is a DFRobot-specific GDI display interface, which uses an 18pin-FPC cable to connect to the screen, making screen connection more convenient.

    The pin mapping is as follows:

    FPC PINS Firebeetle 2 ESP32-C5 PINS Description
    VCC 3V3 3V3
    LCD_BL 15/D13 Backlight
    GND GND GND
    SCLK 23/SCLK SPI clock
    MOSI 24/MOSI Master output, slave input
    MISO 25/MISO Master input, slave output
    LCD_DC 8/D2 Data/Command
    LCD_RST 26/D3 Reset
    LCD_CS 27/D6 TDT chip select
    SD_CS 3/A2 SD card chip select
    FCS NC Font library chip select
    TCS 6/D12 Touch chip select
    SCL 10/SCL I2C clock
    SDA 9/SDA I2C data
    INT 7/D11 INT
    BUSY NC Tear-proof pin
    X1 NC Custom pin 1
