GrovePi I2C Commands

Hi,

This post is for GrovePi users.
As I had to write my own C/C++ code to communicate with GrovePi, I first analyzed I2C commands used to drive the GrovePi from the raspberry (the I2C master).
The analyzed data is from the firmware 1.1 (open source).

Hoping it may be usefull for you.

Regards,
JL

Re: UVC Camera support?

The more I read about USB video capture, the more I understand bandwidth in USB1.x is not enougth with Debian...

I didn't find anybody to capture video for a long time...
I hope it would be possible soon and easily.
