I2C multi-byte access through DS90UB913/914?

Gary Teng

Hi all,

My customer is using DS90UB913/4 to control his Aptina sensor. They can access sensor I2C register now, but they're failed to write multi-byte in I2C communication through 913/914 for device initialization.

Can FPD-Link process I2C multibyte communication? If yes, how to do that?

Hello Gary,

Yes it can - the writes have to be one after the other (i.e. a write followed by another write) in order to be sent as a multi-byte write over I2C. You will need a master controller that supports multi-byte writes such as an Aardvark adapter:

Hi Sean,

My customer want to update Aptina sensor's Flash through 913/914. We're checking aptina's document/I2C commend now. Do you have experience in updating Aptina SPI flash througt FPD-Link?
