DS90UB960-Q1: can not communicate with DS90UB935 via i2c

Hello Xuhui,

Is the 935 also pin strapped for synchronous mode? 

Thanks,

Casey 

Hi, Casey,

 935 alreay in synchronous mode, Mode pin's R high is NC, R low is 10k. But 960's sync mode called csi2 mode,it that right?

Hello

     Can you ensure that 960 is linked up first? Do you see stable lock on the channel you connected to 935?

Thanks

Vijay

Hi Vijay,

  There is no lock state show in 960's registers, and 0x5b register always 0x00.

  BTW,i already can use 960+913 get frames. For 960+935, i only change the mode pin to csi mode. 

Thanks

Hello Xuhui

   Looks like the receiver is not locked and that's the reason you dont have remote i2c access. LOCK status can be read from register 0x4D available on the 960

Thanks

Vijay

So, any idea why receiver is not lock?

Hi,Vijay

 I solved it, my pcb layout has some issure. Thank you very much.

 And i want communicate with camera sensor via i2c, which register i need config? 0x5d SlaveID or 0x65 SlaveAlias ??

Xuhui

    If you only have 1 imager, use slaveID. If you have multiple imagers with same i2c address, u can use aliasing to address the cameras

Thanks

Vijay
