DS90UB954-Q1EVM: Why does DS90UB954EVM or DS90UB954EVM cascade Caps between Hole and GND?

these don't matter with ub954 application. pls ignore it in your design.

Dear Steven,



Can you share some deom code on accessing two 953 respectively?



Thanks.

I think you have similar issue before. regarding UB954 and UB964, they are similar when visiting different port's device. you can refer to the script in page22 of UB964EVM user guide. also, in UB954 d/s, it is clear on how to visit different port's camera, which is used to differentiate the camera. (set 0x4c = 0x01 for port0, and 0x4c = 0x12 to port1) thanks.

best regards,

Steven

Dear Steven,

It is just some section initialization code , not an entire initialization code. it is time consuming for designer to understand all 953 and 954 register maps and its initial procedure.

If TI can share an entire demo project, C is preferred,including 954 and 953 initialization and also an image sensor, that can save a lot of time to learn how to use 953-954.

Yes, it is right.
In DS90UB954 d/s, we provide many reg. setting reference for easy-to-use. Also, you can see our app. note inserted into d/s to share how to bring up our UB953/954, which helps our customer to understand how to better use our device and how to make our device in one better position. so unfortunately, we have no c code, but just need our customer and our support team to get to know the usage, and they can configure the UB953/954 based on their real use-case.

best regards,
Steven
