ESP32 LCD/Camera Mode. (Source:ESP32 documentation)

LCD/Camera mode is only supported on I2S0 over a parallel bus. For LCD mode, I2S0 should work at master TX mode. For camera mode, I2S0 should work at slave RX mode. These two modes are not implemented by the I2S driver. Please refer to LCD for details about the LCD implementation. For more information, see ESP32 Technical Reference Manual > I2S Controller (I2S) > LCD Mode [PDF Pg 323 “12.5 Camera-LCD Controller”].
