8bit grey scale

Postby OutoftheBOTS » Fri Aug 10, 2018 6:57 pm

I am helping a friend out with his STM32F4 Ardunio project and have a question I hope you guys don't mind helping me with.

I was reading the datasheet for the OV7725 and can't see how it can be setup to output 8bit grey scale.

Do you guys setup the OV7725 in 8bit grey scale or does the DCMI convert it from 565RGB on the fly or do you guys convert 565RGB in software??
