The Magical Use of SPI Interface Display Screen on MCU

SPI interface display screens are widely used in single-chip microcomputers, mainly in the following aspects:

1. Liquid crystal display (LCD) driver

· Hardware connection: To connect the LCD display screen through the SPI interface, it is usually necessary to connect the SCK, MOSI, CS, DC, RESET and other pins.

· Initialization configuration: Configure the SPI peripherals in the single-chip microcomputer, set the clock frequency, mode, data bit width and other parameters to achieve communication with the LCD.

· Application scenario: The SPI driving LCD method is very common in embedded systems and is suitable for various applications that need to display information, such as instrumentation, smart home, etc.

2. High-speed data transmission

· Transmission rate: The SPI module transmission rate of modern single-chip microcomputers and PLCs can reach several megahertz or even tens of megahertz, which is very suitable for high-speed data transmission scenarios.

· Application example: In portable devices such as smart bracelets, the single-chip microcomputer communicates with flash memory chips, display screens, etc. at high speed through the SPI interface, which improves the performance and user experience of the device.
