MCU-MPU bridge emulation support

[KostyaEsmukov]

This issue is to keep track of MicroProcessor-MicroController bridge emulation support status.

On Arduino Yun and Intel Edison it's done with Serial interfaces. From Linux side it looks like a tty device (/dev/ttyATH0). At first sight it should be enough to simply pipe this device. However, this approach doesn't take into account MCU flashing.

Some related protocols:

• Firmata
• MCUIO
• Arduino Yun Bridge

Thanks for adding the issue. Actually, this is something we did not take into consideration in a first moment as it is not clear to me how to allow virtualization of the Arduino YUN in the case in which such a kind of technologies are used.

The MCUIO protocol is supported in Arduino YUN thought BathOS:

https://github.com/linino/bathos-mcuio

and through Linux-side libraries such as

https://github.com/ideino/ideino-linino-lib

which if I'm not wrong should be a wrapper around the on-off library.
