Dear NXP,
I am trying to obtain CCIR656 format video signal with ADV7280a, and then process it through CSI of RT1052 and display it on LCD screen.The CSI setting codes are as follows:
camera_config.pixelFormat=kCAMERA_InterfaceCCIR656;//CCIR656 Signal from ADV7280a
camera_config.bytesPerPixel=APP_BPP;//APP_BPP=2
camera_config.resolution=FSL_VIDEO_RESOLUTION(lcddev.width,lcddev.height);
camera_config.frameBufferLinePitch_Bytes=lcddev.width*APP_BPP;
camera_config.interface=kVIDEO_PixelFormatYUYV ; // YUV422
camera_config.controlFlags=APP_CAMERA_CONTROL_FLAGS;
For RGB565 format, the parameter of APP_CAMERA_CONTROL_FLAGS is defined as follows:
#define APP_CAMERA_CONTROL_FLAGS (kCAMERA_HrefActiveHigh | kCAMERA_VsyncActiveLow | kCAMERA_DataLatchOnRisingEdge)
enum _camera_flags
{
kCAMERA_HrefActiveLow = 0U, /*!< HREF is active low. */
kCAMERA_HrefActiveHigh = (1U << 0U), /*!< HREF is active high. */
kCAMERA_DataLatchOnFallingEdge = 0U, /*!< Pixel data latched at falling edge of pixel clock. */
kCAMERA_DataLatchOnRisingEdge = (1U << 1U), /*!< Pixel data latched at rising edge of pixel clock. */
kCAMERA_VsyncActiveLow = 0U, /*!< VSYNC is active low. */
kCAMERA_VsyncActiveHigh = (1U << 2U), /*!< VSYNC is active high. */
};
My question is, if CCIR656 format is adopted and there are no HREF and VSYNC hardware synchronization signals, how to set this parameter of APP_CAMERA_CONTROL_FLAGS?
