DM8168 视频输出接口



你好, 视频输出接口VOUT0怎么找不到DE信号?没有吗?VOUT0只能使用内嵌同步模式吗?

谢谢

  • 你好;

            内嵌或者离散都是可以的;

            你查一下你的display init 的配置

            

    /**
     * \brief DVO Format
     */
    typedef enum
    {
        VDIS_DVOFMT_SINGLECHAN = 0,
        /**< Ouput data format is single channel with embedded sync */
        VDIS_DVOFMT_DOUBLECHAN,
        /**< Output data format is dual channel with embedded sync */
        VDIS_DVOFMT_TRIPLECHAN_EMBSYNC,
        /**< Output data format is tripple channel with embedded sync */
        VDIS_DVOFMT_TRIPLECHAN_DISCSYNC,
        /**< Ouptut data format is triple channel with discrete sync */
        VDIS_DVOFMT_DOUBLECHAN_DISCSYNC,
        /**< Output data format is dual channel with discrete sync */
        VDIS_DVOFMT_MAX
        /**< This should be the last Enum */
    } VDIS_DIGITAL_FMT_E;
  • 你好,谢谢回复,不过我是想找VOUT0的DE输出引脚,在文档和芯片的原理图封装里都没有找到这个引脚。

  • 你看一下 IO:AR8,  引脚 VOUT[0]_AVID ; 这个就是Vout0的DE信号的输出;
