The process begins at the image sensor. The CX3 configures the ISI to match the output format of the sensor (e.g., MIPI CSI-2 or Parallel). The CX3-UVC firmware must be written to accommodate specific sensor timings—Horizontal Sync (HSYNC), Vertical Sync (VSYNC), and Pixel Clock (PCLK).
For advanced users, rebuild the CX3 firmware using the . Key parameters in the cycx3_uvc.h file: cx3-uvc driver
