How can I call a function from the PC and execute on micropython?

I found this,
viewtopic.php?f=6&t=1020&hilit=pc+control&start=10

and a few references to this,

I have a PC side Python application that needs to control the pyboard, and it seems silly to write a wrapper for every function in pyb.

That's pretty much what you need to do.

You could use pyboard.py to send python code over.

You could also send python code to be executed via eval, although this isn't generally very secure.

Thanks Dave,

`That's pretty much what you need to do.`

Of the 3 possibilities that I mention, which one were you referring to?

I have no security requirements.

All of them are basically variations on the same theme. The host has no way of directly controlling peripherals on the mivropython board. You need to send something across a link and have the micropython board actually control the peripheral.

Here is a solution that others may find useful,
