Hello,

Do you know how to configure the bit mapping of ds90ub940-q1 when paired with ds90ub947-q1? OLDI mapping and SPWG mapping?

Thanks

    Hello Dongbao,

    You don't need to configure bit mapping on 940 to pair with 947. On the 947 side, ensure the input mapping corresponds to the RGB output format of the source. No matter how the 947 is configured, it will properly map the RGB data to CSI-2 according to the mapping schemes in the 947 datasheet. So just make sure that you use the right mode so that your source is outputting the right RGB positions for the 947 mode.

    Best Regards,
    Casey
