[PD] LibPd on microcontroller

[cyrille henry]

heavy compile pd patch in C code.
you can then compile this C code to whatever architecture/platform you wish.

cheers

However, I have only encountered LibPd in the context of other applications (processing, openFrameworks) and mobile devices so far. Do you think it could work on an ESP8266? I'm also a bit concerned about efficiency, as computation power is rather limited:
