You can customize your GPIF II state machine.
As per your comments, the start of the frame is detected by the pulse in the VSYNC line. However, the VSYNC will go low within a short duration of time and will not stay high during the active portion of the frame.
Can you please let me know how can we identify the blanking period of the frame in your case?
Can you please share sensor datasheet?
What is value of VS_H? Is it configurable?
the sensor is ov5642
Hello Mini Nano,
--Please let me know, What is the time between VSYNC going high and HSYNC going high?
-We didn't find VS_H value in the data sheet.measure the VS_H value and share it.
