Re: Documentation on connecting?

There's a note that when in digital mode the PA5 pin is 5V tolerant. See the superscript note after the table.

Re: Flipping the camera up-side-down

We should be able to add vertical flip and horizontal mirror output to the sensor class. OmniVision sensors support this. The OV7725 does I know. For the OV2640 you can find the data sheet by googling for it here: http://www.uctronics.com/download/cam_module/OV2640DS.pdf See Page 22. There's a verti...

No, When Ibrahim did the initial development he didn't use the PYB module. As for the MLX code. That is all working now and has been tested.

If you want to bit bang the I2C... see this file for how to drive the lines perfectly:

Funny, but, we should just have python wrappers so you can call that code.

Live streaming is just JPEG compressed images. We don't have any fancy hardware encoder. h264 is usually implemented via a custom co-processor. You really only get that feature on super high end stuff.
