DS90UB928Q-Q1: How to write White balance LUTs via I2C

Hello, we received your query. We will review and get back to you.

Hi Liam,

I have the similar question too. The datasheet did not explain properly the write sequence, it is too general. Can you explain more details about:

A)For initial LUT loading: I'm doing it in 5 write packets
1) [slave address] [white balance register = 0x2A] [white balance off = 0x00]
2) [slave address] [white balance register = 0x2A] [red page select = 0x40] [256 bytes red data......]
3) [slave address] [white balance register = 0x2A] [green page select = 0x40] [256 bytes green data......]
4) [slave address] [white balance register = 0x2A] [blue page select = 0x40] [256 bytes blue data......]
5) [slave address] [white balance register = 0x2A] [white balance on = 0x20]
am I correct?

B)for partial reloading, in datasheet mentioned about we are allow to update some part of the LUT, what is the sequence? can we select the specific address in the LUT page?

Thanks & Regards
