DS90UB953-Q1: How to generate Fsync for image sensor?

Other Parts Discussed in Thread: ALP

Dear Sir,

I had tested image sensor stream is ok in HOST mode(do not need external fync), I want to use Fsync to trigger image sensor which is working at slave mode(external Fsync is needed).

BUT, in ALP ,I cannot generate this Fsync, Can you give me some advice?  I use GPIO3(953 side) to output Fsync.

Thanks.

    Tiger,

    As you are using GPIO3 on the 953 side, its correct you choose BC GPIO3 as FrameSync. You then choose FSyncREf correctly as RX0 BC. Make sure in Registers tab, RX0 is chosen for "Select RX Port". After programming 953 GPIO registers 0x0D and 0x0E (as described below), press the START button.

    Also, on the remote registers tab, you have to set 953 registers 0x0D and 0x0E. In register 0x0D, set bit 7 (GPIO_RMTEN) to enable remote GPIO3 and in register 0x0E, set bit 7 (GPIO3_OUT_EN) to enable GPIO3 output.

    Thanks,
    Vishy
