Part Number: DS90UB934-Q1

Hi Team,

My customer now use 934 in their project and found that they can't visit the camera from 934.

The configuration is as following:

OV2718+OV491+DS90UB933

w 0x3E, 0x11;/*Open 934 spread spectrum function*/
w 0xB9, 0x1F;/*Configure 934 error rate*/
w 0x4C, 0x01;/*Allows writing to RX port 0 register*/
w 0x6E, 0x99;/*Pull up all GPIO ports of UB933*/
w 0x6F, 0x99;/*Pull up all GPIO ports of UB933*/
w 0x58, 0x58; /* Enable channel*/
w 0x5D, 0x48;/*Set CAMERA virtual ID*/
w 0x65, 0x48;/*Set the actual ID of CAMERA*/

Could you kindly help to check the configuration？

    Hello Amilie,

    Any reason why you pull-up all GPIOs of the UB933?
    In reg 0x5D is not setting the virtual ID, it is setting the Slave-ID, which is the I2C address of the Image sensor/ ro the companion chip or any other prepheral on the camera board.
    In reg 0x65 you define the Alias-ID of your slave.
    If you want to communicate with more than one slave, you need to define them all in other Slave-ID and SlaveAlias registers.
