Hallow everyone!
I want to make a circuit that captures photo form webcam and saves it in to a sd card after about five minute interval.
I'm using the 18f8722 and max3421 chip.
I can write data to sd card but the problem is that i don't know nothing about OTG.

How to initialize the webcam and how to get the raw data form it ?

I want the raw data of the picture and then save it as a text file.
Why raw data instead of compressed data (jpeg or other compressed format) ?
->for simplicity.

How to get started with OTG form very beginning? Any advise will be very helpful.:grin:
