Added arduino-nano to BOARD_INSUFFICIENT_MEMORY/BOARD_BLACKLIST following suit of how arduino-uno is marked, as arduino-nano is mostly an Uno in a different form factor. |

Lua interactive interpreter
About
This example shows how to run a Lua Read-Eval-Print loop. It works in a similar way to the lua shell that comes with your operating system's default lua installation.
How to run
Type make all flash to program your board. The lua interpreter communicates
via UART (like the shell).
It is not recommended to use make term because the default RIOT terminal messes
up the input and output and the REPL needs multi-line input. Instead, use something
like miniterm.py from pyserial:
miniterm.py --eol LF --echo /dev/ttyACM0 115200
By default only some of the builtin modules are loaded, to preserve RAM. See
the definition of BARE_MINIMUM_MODS in main.c.
Using the interpreter
See the Lua manual for the syntax of the language.
Each piece of single or multi-line input is compiled as a chunk and run. For this reason, issuing "local" definitions may not work as expected: the definitions will be local to that chunk only.
