Driver for Arducam Mini 2MP Plus – OV2640

[nbellotto]

Description

Currently there is no support for cameras in RIOT, which would be very useful for many IoT applications with computer vision. To this end, I've implemented a simple RIOT program/module to grab JPEG frames from a rather popular SPI camera, the Arducam Mini 2MP Plus – OV2640, by reverse engineering the original Arduino libraries for this device.

I've tested the software successfully on two boards already: an Arduino Nano 33 IoT and a Mega 2560 rev3. The frames are sent via serial port and visualised by a simple Python program (using OpenCV). I've tested different resolutions: everything works fine and, for small resolutions, at a decent framerate.

Unfortunately, I don't have the time to convert my code into a proper RIOT driver, so I'd like to "pass the torch" to someone else who might be interested in doing so. I can provide all the (partly documented) code, including the Python program. I can also test any new drivers on my Arduino boards.
