DVP & Flex Bus

Is Digital Video Port interface same as Flex Bus interface?

Can I use K series MCUs to connect to camera module via Digital Video Port interface?

Hi Joseph,

Which DVP product you are referring to? FlexBus might fit with some of them but not all in the world. Would you please help to provide more details? Thanks for your patience!

Have a great day,
Kan

I've researched on the appnote, but it's talking about connecting via GPIO instead of Flex Bus. Also, I'm still not sure whether DVP output can be connected via Flex Bus or not.

Hi Joseph,

Just wanted to point that AppNote out to you and others and to say it has been implemented by more than one customer successfully.

Hi Joseph Chen,

I have looked into the data sheet of OV9712, but found its interface is different from flexbus signals, so I think this DVP interface can not be connected with flexbus, while the GPIO solution should be ok.

Have a great day,
Kan
