Arduino and kernel/OS

Hello,

I am not sure about the sens of my question but there it is:

What kernel/OS is arduino using to manage the code it runs? None? it just executes code?
Is is baremetal ?

I plan to buy a lcd screen (graphical, to make a one interface app, remotely like a tablet, but fitting small space).

So confused am I :slight_smile:

Thanks,

It's bare metal.

For something like that, you should look into a raspberry pi. Maybe the A+ without headers will be good to use.

good to know!

Thanks for your answers :)
