2. EPS32 with Different Interface LCD
2.1 MIPI DSI Interface LCD
MIPI-DSI is a commonly used high-speed serial interface on LCDs with high resolution and refresh rates. ESP32-P4 boasts several advanced features in hardware interfaces and graphic processing. It supports the MIPI-DSI interface, capable of outputting images in 24-bit RGB888 color format. Additionally, ESP32-P4 integrates a JPEG hardware codec and features 2D-DMA and Pixel Processing Accelerator (PPA) modules for graphics acceleration, ensuring excellent performance in image processing tasks such as scaling, rotation, and layer blending. Furthermore, the HP core of ESP32-P4 is equipped with 768 KB of on-chip SRAM. When external PSRAM is available, it can be used as cache access, providing more cache space for HMI applications, effectively improving the real-time responsiveness of screen display applications.
