DS90UB954-Q1: Configuration Consultation.

Part Number: DS90UB954-Q1
Hi,
For example, we want to read 933 sensor ID on module side.

933 address is 0xb0. Sensor or or ISP address is 0xda (both 8bit addresses)

The configuration is as follows:

Write (954_addr, 0x5c, 0xb0)

Write (954_addr, 0x5d, 0xda)

Write (954_addr, 0x65, 0xda)

Can you read and write the 0xda address directly after configuration?

Or how to read the address of 0XDA?

thanks.

    Hello Wu,

    This configuration is correct. It needs to be done on a per-port basis though, so if your camera is connected to RX0, then you must select RX0 in the FPD3_PORT_SEL register first before writing the above commands by setting 0x4C = 0x01. 

    Once all that configuration is done then you should be able to access the remote slave by reading/writing to address 0xDA (8 bit).

    Best Regards,

    Casey
