CrowPanel 2.01inch-HMI ESP32 Watch Display Wiring Pins:

SPI (Serial Peripheral Interface) display mode is a communication method that connects an MCU to a display via a serial bus. It requires only a small number of GPIO pins for data transmission and features a simple hardware connection.

The SPI interface is suitable for small- and medium-sized TFT, OLED, and LCD displays. It offers good compatibility, a well-established development ecosystem, and low cost; however, due to bus bandwidth limitations, its refresh rate is typically lower than that of parallel display interfaces such as RGB and MIPI DSI.

SPI Pin connection

constexpr uint8_t PIN_LCD_POWER = 40;        // Use GPIO40 to control the LCD power rail.
constexpr uint8_t PIN_PERIPHERAL_POWER = 47; // Use GPIO47 to enable the shared peripheral power rail.
constexpr uint8_t PIN_LCD_BACKLIGHT = 13;    // Use GPIO13 as the LCD backlight PWM output.
constexpr uint8_t PIN_LCD_TE = 21;           // Use GPIO21 for the LCD tearing-effect synchronization signal.
