Compiler/DS90UB934-Q1: sensor

Hello, 

The 934 is a parallel output but the 964 is a CSI-2 output for starters. I'm not sure how you are connecting the 964/934 to a display, but you may want to check that.

0x4c,0x02  - this should be 0x01 for Port 0 

0x6d,0x7f  - are you using RAW10? (934+933)

And the register 0x58,0x5c,0x5d,0x65,0x6e of 934 is failed to set.How do i solve this? - what do you mean you can't write to it? You are locally connected to the 934 and trying to change it in ALP?

Thanks, 

Sally 

Thanks for replying.

We use to 934 receive the video from the camera (933+ISX019) which is 8bit output.We use RAW10 for this.

Now I can write 0x58,0x5c,0x5d,0x65,0x6e.

I have set 0x4c,0x01  0x6d,0x7f  for port 0.But there is still no data output from 934.

Did you make sure that you are operating in RAW10 mode when setting the mode select on the 934? Is the PCLK within the 50-100 MHz range? Is PASS high? Check the pin or register 0x04. 

Register 0x04 is 0xcc,

0x4e is 0x04,

0x4d is 0x13

0x4e is 0x04

0x4f is 0x31

0x50 is 0x6b

0x77 is 0xe5

0x6d is 0x7f

It looks like your PCLK is slightly under 50 MHz which is the minimum for RAW10 mode. Can you measure yourself and double check the PCLK frequency on the scope?
